  • C# DataSet CheckBox Column With DevExpress DataGrid

    - by Goober
    Scenario I have a DevExpress DataGrid which is bound to a DataSet in C#. I want to populate each dataset row to contain a string in the first column and a checkbox in the second. My code below doesn't work quite how I want it to, and I'm not sure why..... The Code As you can see I've declared a dataset, but when I try and pass in a new checkbox object to the 2nd column it just displays the system name for the checkbox. DataSet prodTypeDS = new Dataset(); DataTable prodTypeDT = prodTypeDS.Tables.Add(); prodTypeDT.Columns.Add("MurexID", typeof(string)); prodTypeDT.Columns.Add("Haganise",typeof(CheckBox)); //WHY DOES THIS NOT WORK? //(Displays "System.Windows.Forms.CheckBox, CheckState: 0") //Instead of a checkbox. CheckBox c = new CheckBox(); prodTypeDS.Tables[0].Rows.Add("Test",c); //This doesn't work either.... prodTypeDS.Tables[0].Rows.Add("Test",c.CheckState); ......I hope this is just because it's a DevExpress datagrid....

  • Excel VBA Text To Column

    - by Pat
    This is what I currently have: H101 John Doe Jane Doe Jack Doe H102 John Smith Jane Smith Katie Smith Jack Smith And here is what I want: H101 John Doe H101 Jane Doe H101 Jack Doe H102 John Smith H102 Jane Smith H102 Katie Smith H102 Jack Smith Obviously I want to do this on a bigger scale. The number of columns is between 1 & 6, so I cant limit it that way. I was able to get a script that allows me to put each individual on one row. However, I am having a hard time getting the first column to copy over to each row. Sub ToOneColumn() Dim i As Long, k As Long, j As Integer Application.ScreenUpdating = False Columns(2).Insert i = 0 k = 1 While Not IsEmpty(Cells(k, 3)) j = 3 While Not IsEmpty(Cells(k, j)) i = i + 1 Cells(i, 1) = Cells(k, 1) //CODE IN QUESTION Cells(i, 2) = Cells(k, j) Cells(k, j).Clear j = j + 1 Wend k = k + 1 Wend Application.ScreenUpdating = True End Sub Like I said, it was working fine to get everyone each on their own row, but can't figure out how to get that first column. It seems like it should be so simple, but it's bugging me. Any help is greatly appreciated.

  • Skipping one item in the column

    - by zurna
    I created a simple news website. I store both videos and images in IMAGES table. Videos added have videos and images added have images stored in a column called ImagesType. Images and Videos attached to a news is stored in ImagesID column of the NEWS table. My problem occurs when I need to display the first image of a news. i.e. IMAGES table: ImagesID ImagesLgURL ImagesType 1 /FLPM/media/videos/0H7T9C0F.flv videos 2 /FLPM/media/images/8R5D7M8O.jpg images 3 /FLPM/media/images/0E7Q9Z0C.jpg images NEWS table NewsID ImagesID NewsTitle 1 1;2; Street Chic: Paris ERROR 2 3; Paris Runway NO ERROR The following code give me an error with the 2nd news item because the first ImageID stored in the list is not an image but a video. I need to figure out a way to skip the video item and display the next image. I hope I made sense. SQL = "SELECT NEWSID, CATEGORIESID, IMAGESID, NEWSTITLE, NEWSSHORTDESC, NEWSACTIVE, NEWSDATEENTERED" SQL = SQL & " FROM NEWS N" SQL = SQL & " WHERE NEWSACTIVE = 1" SQL = SQL & " ORDER BY NEWSDATEENTERED DESC" Set objNews = objConn.Execute(SQL) Do While intLooper1 <= 3 And Not objNews.EOF IMAGES = Split(Left(objNews("IMAGESID"),Len(objNews("IMAGESID"))-1), ";") SQL = "SELECT ImagesID, ImagesName, ImagesLgURL, ImagesSmURL, ImagesType" SQL = SQL & " FROM IMAGES I" SQL = SQL & " WHERE ImagesID = " & IMAGES(0) & " AND ImagesType = 'images'" Set objLgImage = objConn.Execute(SQL) <div> <a href="?Section=news&SubSection=redirect&NEWSID=<%=objNews("NEWSID")%>"> <img src="<%=objLgImage("ImagesLgURL")%>" alt="<%=objLgImage("ImagesName")%>" /> </a> </div> <% objLgImage.Close Set objLgImage = Nothing intLooper1 = intLooper1 + 1 objNews.MoveNext Loop %>

  • Finding Common Phrases in SQL Server TEXT Column

    - by regex
    Short Desc: I'm curious to see if I can use SQL Analysis services or some other SQL Server service to mine some data for me that will show commonalities between SQL TEXT fields in a dataset. Long Desc I am looking at a subset of data that consists of about 10,000 rows of TEXT blobs which are used as a notes column in a issue tracking (ticketing) software. I would like to use something out of the box (without having to build something) that might be able to parse through all of the rows and find commonly used byte sequences in the "Notes" column. In other words, I want to find commonly used phrases (two to three word phrases, so 9 - 20 character sections of the TEXT blob). This will help me better determine if associate's notes contain similar phrases (troubleshooting techniques) that we could standardize in our troubleshooting process flow. Closing Note I'd really rather not build an application to do this as my method will probably not be the most efficient way to do it. Hopefully all this makes sense. Please let me know in the comments if anything needs clarification.

  • SQL Server - Multi-Column substring matching

    - by hamlin11
    One of my clients is hooked on multi-column substring matching. I understand that Contains and FreeText search for words (and at least in the case of Contains, word prefixes). However, based upon my understanding of this MSDN book, neither of these nor their variants are capable of searching substrings. I have used LIKE rather extensively (Select * from A where A.B Like '%substr%') Sample table A: ID | Col1 | Col2 | Col3 | ------------------------------------- 1 | oklahoma | colorado | Utah | 2 | arkansas | colorado | oklahoma | 3 | florida | michigan | florida | ------------------------------------- The following code will give us row 1 and row 2: select * from A where Col1 like '%klah%' or Col2 like '%klah%' or Col3 like '%klah%' This is rather ugly, probably slow, and I just don't like it very much. Probably because the implementations that I'm dealing with have 10+ columns that need searched. The following may be a slight improvement as code readability goes, but as far as performance, we're still in the same ball park. select * from A where (Col1 + ' ' + Col2 + ' ' + Col3) like '%klah%' I have thought about simply adding insert, update, and delete triggers that simply add the concatenated version of the above columns into a separate table that shadows this table. Sample Shadow_Table: ID | searchtext | --------------------------------- 1 | oklahoma colorado Utah | 2 | arkansas colorado oklahoma | 3 | florida michigan florida | --------------------------------- This would allow us to perform the following query to search for '%klah%' select * from Shadow_Table where searchtext like '%klah%' I really don't like having to remember that this shadow table exists and that I'm supposed to use it when I am performing multi-column substring matching, but it probably yields pretty quick reads at the expense of write and storage space. My gut feeling tells me there there is an existing solution built into SQL Server 2008. However, I don't seem to be able to find anything other than research papers on the subject. Any help would be appreciated.

  • How to write to a varchar(max) column using ODBC

    - by andyjohnson
    Summary: I'm trying to write a text string to a column of type varchar(max) using ODBC and SQL Server 2005. It fails if the length of the string is greater than 8000. Help! I have some C++ code that uses ODBC (SQL Native Client) to write a text string to a table. If I change the column from, say, varchar(100) to varchar(max) and try to write a string with length greater than 8000, the write fails with the following error [Microsoft][ODBC SQL Server Driver]String data, right truncation So, can anyone advise me on if this can be done, and how? Some example (not production) code that shows what I'm trying to do: SQLHENV hEnv = NULL; SQLRETURN iError = SQLAllocEnv(&hEnv); HDBC hDbc = NULL; SQLAllocConnect(hEnv, &hDbc); const char* pszConnStr = "Driver={SQL Server};Server=127.0.0.1;Database=MyTestDB"; UCHAR szConnectOut[SQL_MAX_MESSAGE_LENGTH]; SWORD iConnectOutLen = 0; iError = SQLDriverConnect(hDbc, NULL, (unsigned char*)pszConnStr, SQL_NTS, szConnectOut, (SQL_MAX_MESSAGE_LENGTH-1), &iConnectOutLen, SQL_DRIVER_COMPLETE); HSTMT hStmt = NULL; iError = SQLAllocStmt(hDbc, &hStmt); const char* pszSQL = "INSERT INTO MyTestTable (LongStr) VALUES (?)"; iError = SQLPrepare(hStmt, (SQLCHAR*)pszSQL, SQL_NTS); char* pszBigString = AllocBigString(8001); iError = SQLSetParam(hStmt, 1, SQL_C_CHAR, SQL_VARCHAR, 0, 0, (SQLPOINTER)pszBigString, NULL); iError = SQLExecute(hStmt); // Returns SQL_ERROR if pszBigString len > 8000 The table MyTestTable contains a single colum defined as varchar(max). The function AllocBigString (not shown) creates a string of arbitrary length. I understand that previous versions of SQL Server had an 8000 character limit to varchars, but not why is this happening in SQL 2005? Thanks, Andy

  • Magento Set Grid to Filter Automatically by Current Day using Existing Datetime Column in Grid

    - by Tegan Snyder
    In Magento I'm creating a custom module and would love to be able to filter automatically by the datetime column so that the intial grid listing shows only entities related to "todays" date. Here is my datetime column: $this->addColumn('ts', array( 'header' => $hlp->__('Activated'), 'align' => 'left', 'index' => 'ts', 'type' => 'datetime', 'width' => '160px', )); I'm think there should be a way for me to just add a filter to the collection like so: $now = Mage::getModel('core/date')->timestamp(time()); $dateTime = date('m/d/y h:i:s', $now); $collection = Mage::getModel('mymodule/items')->getCollection() ->addFieldToFilter('ts', $dateTime); But this doesn't work? Am I using the wrong filter? My "ts" field in the database is a "datetime" field, but the default magento "From: " - "To:" date range selectors don't use hours, minutes, seconds. Any ideas? Thanks, Tegan

  • How to make Jtable column contain checkboxes?

    - by theraven
    Preface: I am horrible with java, and worse with java ui components. I have found several different tutorials on how to add buttons to tables, however I am struggling with adding checkboxes. I need to have a column that draws a text box ticked on default (cell renderer i think handles that), then on click of tickbox, unticks the box, redraws said box, and fires off an event somewhere I can track. currently I have a custom cellrenderer: public class GraphButtonCellRenderer extends JCheckBox implements TableCellRenderer { public GraphButtonCellRenderer() { } public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if(isSelected) setSelected(true); else setSelected(false); setMargin(new Insets(0, 16, 0, 0)); setIconTextGap(0); setBackground(new Color(255,255,255,0)); return this; }} Which currently handles drawing the tick box, but only ticks and unticks the box if that row is selected. But I don't know how to handle the events. Really what I am asking is possibly a link to a good tutorial on how to add checkboxes cleanly to a JTable. Any assist is greatly appreciated :)

  • Fluent NHibernate mapping List<Point> as value to single column

    - by Paja
    I have this class: public class MyEntity { public virtual int Id { get; set; } public virtual List<Point> Vectors { get; set; } } How can I map the Vectors in Fluent NHibernate to a single column (as value)? I was thinking of this: public class Vectors : ISerializable { public List<Point> Vectors { get; set; } /* Here goes ISerializable implementation */ } public class MyEntity { public virtual int Id { get; set; } public virtual Vectors Vectors { get; set; } } Is it possible to map the Vectors like this, hoping that Fluent NHibernate will initialize Vectors class as standard ISerializable? Or how else could I map List<Point> to a single column? I guess I will have to write the serialization/deserialization routines myself, which is not a problem, I just need to tell FNH to use those routines. I guess I should use IUserType or ICompositeUserType, but I have no idea how to implement them, and how to tell FNH to cooperate.

  • Query column and everything subordinate (hard to describe, non native speaker, PLS let me explain)

    - by MAD9
    A few weeks ago, I asked a question about how to generate hierarchical XML from a table, that has a parentID column. It all works fine. The point is, according to the hierarchy, I also want to query a table. I'll give you an example: Thats the table with the codes: ID CODE NAME PARENTID 1 ROOT IndustryCode NULL 2 IND Industry 1 3 CON Consulting 1 4 FIN Finance 1 5 PHARM Pharmaceuticals 2 6 AUTO Automotive 2 7 STRAT Strategy 3 8 IMPL Implementation 3 9 CFIN Corporate Finance 4 10 CMRKT Capital Markets 9 From which I generate (for displaying in a TreeViewControl) this XML: <record key="1" parentkey="" Code="ROOT" Name="IndustryCode"> <record key="2" parentkey="1" Code="IND" Name="Industry"> <record key="5" parentkey="2" Code="PHARM" Name="Pharmaceuticals" /> <record key="6" parentkey="2" Code="AUTO" Name="Automotive" /> </record> <record key="3" parentkey="1" Code="CON" Name="Consulting"> <record key="7" parentkey="3" Code="STRAT" Name="Strategy" /> <record key="8" parentkey="3" Code="IMPL" Name="Implementation" /> </record> <record key="4" parentkey="1" Code="FIN" Name="Finance"> <record key="9" parentkey="4" Code="CFIN" Name="Corporate Finance"> <record key="10" parentkey="9" Code="CMRKT" Name="Capital Markets" /> </record> </record> </record> As you can see, some codes are subordinate to others, for example AUTO << IND << ROOT What I want (and have absolutely no idea how to realise or even, where to start) is to be able to query another table (where one column is this certain code of course) for a code and get all records with the specific code and all subordinate codes For example: I query the other table for "IndustryCode = IND[ustry]" and get (of course) the records containing "IND", but also AUTO[motive] and PHARM[aceutical] (= all subordinates) Its an SQL Express Server 2008 with Advanced Services.

  • FluentNHibernate, getting 1 column from another table

    - by puffpio
    We're using FluentNHibernate and we have run into a problem where our object model requires data from two tables like so: public class MyModel { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual int FooId { get; set; } public virtual string FooName { get; set; } } Where there is a MyModel table that has Id, Name, and FooId as a foreign key into the Foo table. The Foo tables contains Id and FooName. This problem is very similar to another post here: http://stackoverflow.com/questions/1896645/nhibernate-join-tables-and-get-single-column-from-other-table but I am trying to figure out how to do it with FluentNHibernate. I can make the Id, Name, and FooId very easily..but mapping FooName I am having trouble with. This is my class map: public class MyModelClassMap : ClassMap<MyModel> { public MyModelClassMap() { this.Id(a => a.Id).Column("AccountId").GeneratedBy.Identity(); this.Map(a => a.Name); this.Map(a => a.FooId); // my attempt to map FooName but it doesn't work this.Join("Foo", join => join.KeyColumn("FooId").Map(a => a.FooName)); } } with that mapping I get this error: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has invalid child element 'join' in namespace 'urn:nhibernate-mapping-2.2'. List of possible elements expected: 'joined-subclass, loader, sql-insert, sql-update, sql-delete, filter, resultset, query, sql-query' in namespace 'urn:nhibernate-mapping-2.2'. any ideas?

  • CSS column height different on Opera/IE to FF

    - by Infiniti Fizz
    Hi all, Thanks to everyone who helped with my last question but I've got a new browser-independent problem: For some reason, the image navigator (not yet functioning) on a website I'm working on is currently not displaying in the correct place on Firefox. It appears in the right place in IE8 and Opera but Firefox seems to have a problem with it. As can be seen in the below image, the imageContainer div (the image and the left/right arrows) appears on top of the footer, this is how it should look i.e. how it looks in IE8 and Opera. But in the image below, the imageContainer div is cutting into the footer div for some reason, and I don't know why. imageContainer has a margin-top: 110px; to get it in the right place at the bottom of its column. There are 2 columns, the left housing the paragraphs and imageContainer and the right housing the Calendar and contact details. The footer div also has clear: both; Also, it's not just the image that is falling into the footer, it's the arrows as well only they are the same colour as the footer so this isn't immediately apparent. Any ideas why it isn't displaying correctly? Is there a better way of aligning the imageContainer to the bottom of it's column (to keep the box shape of the website) other than using the margin-top to position it? Thanks in advance, infinitifizz

  • Two column layout, navigation div on the right, solution from previous thread didn't seem to work

    - by Tom
    I tried the solution from this thread, but I must be missing something because it doesn't work: <div style="float:left;margin-right:200px"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p> </div> <div style="float:right;width:200px"> <p>navigation</p> </div> It works when the text in the content div (the left one) is short, but when it's long then the div takes up the whole width of the browser and the margin is there, but the right div is pushed below the first one nevertheless. What am I missing? Edit: The goal is to have a fix sized navigation column on the right of the browser window and the left div should get all the space left by the right navigation column (liquid layout).

  • How to determine one to many column name from entity type

    - by snicker
    I need a way to determine the name of the column used by NHibernate to join one-to-many collections from the collected entity's type. I need to be able to determine this at runtime. Here is an example: I have some entities: namespace Entities { public class Stable { public virtual int Id {get; set;} public virtual string StableName {get; set;} public virtual IList<Pony> Ponies { get; set; } } public class Dude { public virtual int Id { get; set; } public virtual string DudesName { get; set; } public virtual IList<Pony> PoniesThatBelongToDude { get; set; } } public class Pony { public virtual int Id {get; set;} public virtual string Name {get; set;} public virtual string Color { get; set; } } } I am using NHibernate to generate the database schema, which comes out looking like this: create table "Stable" (Id integer, StableName TEXT, primary key (Id)) create table "Dude" (Id integer, DudesName TEXT, primary key (Id)) create table "Pony" (Id integer, Name TEXT, Color TEXT, Stable_id INTEGER, Dude_id INTEGER, primary key (Id)) Given that I have a Pony entity in my code, I need to be able to find out: A. Does Pony even belong to a collection in the mapping? B. If it does, what are the column names in the database table that pertain to collections In the above instance, I would like to see that Pony has two collection columns, Stable_id and Dude_id.

  • A GUID as the MySQL table's Primary Key or as a separate column

    - by Ben
    I have a multi-process program that performs, in a 2 hour period, 5-10 million inserts to a 34GB table within a single Master/Slave MySQL setup (plus an equal number of reads in that period). The table in question has only 5 fields and 3 (single field) indexes. The primary key is auto-incrementing. I am far from a DBA, but the database appears to be crippled during this two hour period. So, I have a couple of general questions. 1) How much bang will I get out of batching these writes into units of 10? Currently, I am writing each insert serially because, after writing, I immediately need to know, in my program, the resulting primary key of each insert. The PK is the only unique field presently and approximating the order of insertion with something like a Datetime field or a multi-column value is not acceptable. If I perform a bulk insert, I won't know these IDs, which is a problem. So, I've been thinking about turning the auto-increment primary key into a GUID and enforcing uniqueness. I've also been kicking around the idea of creating a new column just for the purposes of the GUID. I don't really see the what that achieves though, that the PK approach doesn't already offer. As far as I can tell, the big downside to making the PK a randomly generated number is that the index would take a long time to update on each insert (since insertion order would not be sequential). Is that an acceptable approach for a table that is taking this number of writes? Thanks, Ben

    I have a matrix like A= 4.0000 120.0000 92.0000 0 0 37.6000 0.1910 30.0000 10.0000 168.0000 74.0000 0 0 38.0000 0.5370 34.0000 10.0000 139.0000 80.0000 0 0 27.1000 1.4410 57.0000 1.0000 139.0000 60.0000 23.0000 846.0000 30.1000 0.3980 59.0000 5.0000 136.0000 72.0000 19.0000 175.0000 25.8000 0.5870 51.0000 7.0000 121.0000 0 0 0 30.0000 0.4840 32.0000 I want to replace the values of the first column that are greater than '5' to 0, also in the second column if the values are in range 121-130 replace them by 0, if they are in range 131-140 replece by 1, 141-150 by 2, 151-160 by 3... so the result matrix would be A= 4.0000 0.0000 92.0000 0 0 37.6000 0.1910 30.0000 0.0000 4.0000 74.0000 0 0 38.0000 0.5370 34.0000 0.0000 1.0000 80.0000 0 0 27.1000 1.4410 57.0000 1.0000 1.0000 60.0000 23.0000 846.0000 30.1000 0.3980 59.0000 5.0000 1.0000 72.0000 19.0000 175.0000 25.8000 0.5870 51.0000 0.0000 0.0000 0 0 0 30.0000 0.4840 32.0000 How to acomplish this? I was trying something like counter=1; for i = 1: rows if A(i,1) > 5 A(i ,1) = 0; end if A(i,2) > 120 && A(i,2) < 130 A(i ,2) = 0; end counter = counter+1; end Using a case could do the trick?

  • MS SQL - Multi-Column substring matching

    - by hamlin11
    One of my clients is hooked on multi-column substring matching. I understand that Contains and FreeText search for words (and at least in the case of Contains, word prefixes). However, based upon my understanding of this MSDN book, neither of these nor their variants are capable of searching substrings. I have used LIKE rather extensively (Select * from A where A.B Like '%substr%') Sample table A: ID | Col1 | Col2 | Col3 | ------------------------------------- 1 | oklahoma | colorado | Utah | 2 | arkansas | colorado | oklahoma | 3 | florida | michigan | florida | ------------------------------------- The following code will give us row 1 and row 2: select * from A where Col1 like '%klah%' or Col2 like '%klah%' or Col3 like '%klah%' This is rather ugly, probably slow, and I just don't like it very much. Probably because the implementations that I'm dealing with have 10+ columns that need searched. The following may be a slight improvement as code readability goes, but as far as performance, we're still in the same ball park. select * from A where (Col1 + ' ' + Col2 + ' ' + Col3) like '%klah%' I have thought about simply adding insert, update, and delete triggers that simply add the concatenated version of the above columns into a separate table that shadows this table. Sample Shadow_Table: ID | searchtext | --------------------------------- 1 | oklahoma colorado Utah | 2 | arkansas colorado oklahoma | 3 | florida michigan florida | --------------------------------- This would allow us to perform the following query to search for '%klah%' select * from Shadow_Table where searchtext like '%klah%' I really don't like having to remember that this shadow table exists and that I'm supposed to use it when I am performing multi-column substring matching, but it probably yields pretty quick reads at the expense of write and storage space. My gut feeling tells me there there is an existing solution built into SQL Server 2008. However, I don't seem to be able to find anything other than research papers on the subject. Any help would be appreciated.

  • Dynamic evaluation of a table column within an insert before trigger

    - by Tim Garver
    HI All, I have 3 tables, main, types and linked. main has an id column and 32 type columns. types has id, type linked has id, main_id, type_id I want to create an insert before trigger on the main table. It needs to compare its 32 type columns to the values in the types table if the main table column has an 'X' for its value and insert the main_id and types_id into the linked table. i have done a lot of searching, and it looks like a prepared statement would be the way to go, but i wanted to ask the experts. The issue, is i dont want to write 32 IF statements, and even if i did, i need to query the types table to get the ID for that type, seems like a huge waist of resources. Ideally i want to do this inside of my trigger: BEGIN DECLARE @types results_set -- (not sure if this is a valid type); -- (iam sure my loop syntax is all wrong here)... SET @types = (select * from types) for i=0;i<types.records;i++ { IF NEW.[i.type] = 'X' THEN insert into linked (main_id,type_id) values (new.ID, i.id); END IF; } END; Anyway, This is what i was hoping to do, maybe there is a way to dynamically set the field name inside of a results loop, but i cant find a good example of this. Thanks in advance Tim

  • ASP.NET javascript embed in template column

    - by Mahesh
    Hi, I am developing a web page in which a rad grid displays the list of exams. I included a template column which shows count down timer when the exam is going to expire. Code is as given below: <telerik:RadGrid ID="radGrid" runat="server" AutoGenerateColumns="false"> <MasterTableView> <Columns> <telerik:GridTemplateColumn HeaderText="template" DataField="Date"> <ItemTemplate> <script language="JavaScript" type="text/javascript"> TargetDate = '<%# Eval("Date") %>'; BackColor = "white"; ForeColor = "black"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; FinishMessage = "It is finally here!"; </script> <script language="JavaScript" src="http://scripts.hashemian.com/js/countdown.js" type="text/javascript"></script> </ItemTemplate> </telerik:GridTemplateColumn> </Columns> </MasterTableView> </telerik:RadGrid> I am giving DataTable as datasource to this grid. But my problem is , the template column is showing data only for the first record and the value taken is from the last row in the DataTable. For Ex: If I give data as given below, I can see 3 records but with only the first record displaying the counter with last value(10/10/2010 05:43 PM). 02/02/2011 01:00 AM 08/09/2010 11:00 PM 10/10/2010 05:43 PM Could you please help in this?? Thanks, Mahesh

  • Return the Column Name for row with last non-null value "Ms Access 2007"

    - by bri1969
    I have a Table, which contains a list of league players. Each season, we record their Points per Dart. Their total PPD for that season is stored in other tables and extracted through other queries, which in turn are imported to the master table "Player History" at the end of the season for use as historical data. The current query retrieves each players PPD for each season they played, when they played last, and how many seasons played. The code for Last season Played has become too long and unstable to use. it was originally created, and split into two separate columns because a single SQL was to long. (LSP1) and LSP2) which work, but as I add seasons, Access does not like the length of code. In short, i need to find a more simple code that will look at each row, and look in that row for the last non null cell and report which column that last non null value is in. So if a player played seasons 30 & 31, but did not play 32..but did play 33, the Column with the code should be titled Last Season Played, and for that Player, it would state "33" in that cell, indicating that this player last played season "33" I will provide both tables and the query.. Please help
