  • Is possible to set generic type by another class?

    - by Soul_Master
    I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code? Thanks,

  • Viewstate seems to be hijacked inadvertently

    - by dvr
    Hi, we are using asp.net 2.x, we use session state stored in sql server, 2 web servers in loadbalance, iis6. our issue is that in the last 3 months we have had 2 cases where some one using our enquiry form has seen someone else's info e.g. first name and last name. We are not populating the form from objects in session so I have come to the conclusion that the second user has somehow received the viewstate from the first user, after that user has tried to submit and got an error e.g. has posted view state and returned the the same page and the other user has requested that page at the same time (must have been on the same server I am guessing if it is a viewstate issue). have any of you experienced this before? some questions mulling around in my head is how does the worker process know to retun view state to a unique request and how does it determine a unique request etc..

  • What would be the best approach for this?

    - by chobo
    I have a site which has an area that requires authentication. Right now I use the roles attribute on all the controllers in that area, and I run a query to retrieve that users ID, and all their settings. It seems like a code or design smell to me that I am retrieving the userid and settings each time a controller in that area loads up? I'm not sure if I should be using sessions, or if ASP.Net MVC 2.0 provides some unique way to handle this. Another concern is security. Overall, I don't really know which way to turn. Design wise I would like the userId and settings retrieved only once when the user logs into the area. Right now I grab the userId each time a controller loads up, and then if required, I query the database for their settings each time as well.

  • Apply CSS class to invalid controls on web form

    - by user137639
    I need to apply a css class to invalid controls on a web form. I'd like to make it a resusable class. This is what I have so far: public class Validation { public static void ApplyInvalidClass(Page page, string className) { foreach (System.Web.UI.WebControls.BaseValidator bv in page.Validators) { if (!bv.IsValid) { Control ctrl = page.FindControl(bv.ControlToValidate); if (ctrl != null) { if (ctrl is TextBox) { TextBox txt = ctrl as TextBox; txt.CssClass = "invalid"; } if (ctrl is DropDownList) { DropDownList ddl = ctrl as DropDownList; ddl.CssClass = "invalid"; } if (ctrl is CheckBox) { CheckBox cb = ctrl as CheckBox; cb.CssClass = "invalid"; } if (ctrl is HtmlGenericControl) { HtmlGenericControl html = ctrl as HtmlGenericControl; html.Attributes.Add("class", className); } } } } } } The problem is what I call this on a .Net user control, I guess because I'm passing in Page, page.FindControl(bv.ControlToValidate) is always null. Is there a better way to do this?

  • Field annotated multiple times by the same attribute

    - by Jaroslaw Waliszko
    For my ASP.NET MVC application I've created custom validation attribute, and indicated that more than one instance of it can be specified for a single field or property: [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)] public sealed class SomeAttribute: ValidationAttribute I've created validator for such an attribute: public class SomeValidator : DataAnnotationsModelValidator<SomeAttribute> and wire up this in the Application_Start of Global.asax DataAnnotationsModelValidatorProvider.RegisterAdapter( typeof (SomeAttribute), typeof (SomeValidator)); Finally, if I use my attribute in the desired way: [SomeAttribute(...)] //first [SomeAttribute(...)] //second public string SomeField { get; set; } when validation is executed by the framework, only first attribute instance is invoked. Second one seems to be dead. I've noticed that during each request only single validator instance is created (for the first annotation). How to solve this problem and fire all attributes?

  • SqlCeCommand ExecuteNonQuery performance issue

    - by Michael
    I've been asked to resolve an issue with a .Net/SqlServerCe application. Specifically, after repeated inserts against the db, performance becomes increasingly degraded. In one instance at ~200 rows, in another at ~1000 rows. In the latter case the code being used looks like this: Dim cm1 As System.Data.SqlServerCe.SqlCeCommand = cn1.CreateCommand cm1.CommandText = "INSERT INTO Table1 Values(?,?,?,?,?,?,?,?,?,?,?,?,?)" For j = 0 To ds.Tables(0).Rows.Count - 1 'this is 3110 For i = 0 To 12 cm1.Parameters(tbl(i, 0)).Value = Vals(j,i) 'values taken from a different db Next cm1.ExecuteNonQuery() Next The specifics aren't super important (like what 'tbl' is, etc) but rather whether or not this code should be expected to handle this number of inserts, or if the crawl I'm witnessing is to be expected.

  • ASP.NET Speed up DataView sorting/paging

    - by rlb.usa
    I have a page in ASP.NET where I'm using a Repeater to display a record listing. But it's slow as molasses, I've been tasked with speeding it up (sorting,paging). I've got it set up as follows: When user enters page, grab all of the data from the database (500 records, up to 4 relation'ed records) Store it all in Application["MyDataView"] On sort or paging, simply use the data view's internal sort/page method (no db calls) and rebind. I understand that databases can take time to query, but simply to have the DataView call it's sort method (no db calls) takes 10ish seconds, that's an alarmingly slow. Two questions: Why is it taking so long? How can I speed it up? A gridview is not possible.

  • How can I hide a property from going into the form designer file?

    - by user460334
    I am working in VB.NET 2010 Framework 2.0. I don't want to allow some properties from going into form's designer file but the those properties will present on the form(property grid). The behavior of these properties will be same always. I used the following code: <DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> Public Property GradientBegin() As Color = Color.Red But the problem I am facing is that - on the property grid after changing the "GradientBegin" color to other than RED and compiling the program, it is replacing the new changed value to RED again. So I am not able to change the color actually. How can I achieve this? Thanks for any reply in advance.

  • Allow users to enter a variable length list of items in asp.net form

    - by EJB
    I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?

  • ASP.net: Efficient ways to convert DataSets to GenericCollection (Of ObjectType)

    - by jlrolin
    I currently have a function that gets some data from the database and puts it into a dataset. The return type on my function is GenericCollection (Of CustomerDetails) If I do this: Dim dataset As DataSet = Read(strSQL.ToString) 'Gets Data from DB What's the most efficient way to map the dataset results to an collection of objects. More importantly, since I'm using GenericCollection, is there a way to do this in which I can call a function from the ObjectType class (CustomerDetails) that would have a means to converting that specific object. Or is there a way in which I can use a function that would handle all types? Is there a way to do something like: Return returnedResults.TransformDataSet(dataset) In which returnedResults is an object collection Of CustomerDetails, or would it simply be easier to have TransformDataSet return an object collection Of CustomerDetails by itself? Thanks for any help.

  • Cannot locate record in delphi ADO query

    - by Danatela
    I can't locate any record in TADOQuery using PK. First, I was trying to use standard Locate method: PPUQuery.Locate('ID', SpPlansQuery['PPONREC'], []); It always returns False, but manual search (passing the whole query matching ID with given PPONREC which is really slow) finds the desired row. I tried using loPartialKey and switched CursorLocation of query to clUseServer, but it didn't help. Next, I tried to filter my PPUQuery: PPUQuery.Filter := 'ID = ' + VarToStr(SpPlansQuery['PPONREC']); PPUQuery.Filtered := True; PPUQuery.First; But after that the PPUQuery.Eof is True and PPUQuery.RecordCount equals 0. Underlying database is Oracle 9 and the ID is of type INTEGER and is PK of table TPORDER_CMK. PPUQuery.SQL is: SELECT tp.*, la.*, lm.*, ld.*, ld1.*, to_cmk.* FROM ppu_plan.tporder_cmk tp JOIN PPU_PLAN.LARTICLES la ON TP.ARTICLE = LA.ID JOIN PPU_PLAN.LMATERIAL lm ON TP.MATERIAL = lm.id JOIN PPU_PLAN.LCADEP ld ON TP.CADEP = LD.ID JOIN PPU_PLAN.LCADEP ld1 ON TP.PRODUCER = LD1.ID JOIN PPU_PLAN.TORDER_CMK to_cmk ON TP.order_id=TO_cmk.ID WHERE TP.PLAN_ID = :pplan_id What should I try next and how to solve this problem?

  • jQuery AJAX & an ASP.NET web service works locally but not remotely

    - by Alex
    Interesting one here. I have an ASP.NET 1.1 project that contains a web service in it. I'm using jQuery's AJAX functionality to call some services from the client. This is what my code looks like: $.ajax({ type: "POST", url: 'foo.asmx/functionName', data: 'foo1=' + foo1 + '&foo2=' + foo2, dataType: "xml", success: function(xml) { //do something with my xml data }, error: function(request, error){ //handle my error } }); This works great when I run the site from my IDE on localhost. However, when I deploy this site to any other server I get a parsererror error from jQuery. It does not appear to even call my service as I dropped in some code to write a log file to disk and it's not making it there. The same exact XML should be returned from both my localhost and the server I deployed to. Any ideas?

  • Need advice on multitab form in ASP.NET MVC

    - by Sasha
    Hi all, i need an advice on how to implement my form. I have a requirement: i need a form that spans through 5 tabs. Each tab has around 10 fields, some of them empty, some of them must contain data from db and be non editable. Each of these tabs must be a part of one form that is submitted to my controller. The question is: what is the best way to implement this? I was thinking about having partial views on each tab, each view would have its own model class. After form gets filled all data from all partials would go to action that will take care of all of it. Any advices? I am using ASP.NET MVC 1, Entity Framework 1, mvc extensions from Telerik and jQuery

  • open program once with multiple files as arguments from explorer

    - by Jonathan
    I have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio. So how do I open multiple files from explorer context menu in a single instance.

  • I set a global bug catcher in my application for unhandled exceptions and it is picking up all exceptions

    - by user1632018
    I am trying to figure out why this is happing. In my vb.net application I set a global handler in the ApplicationEvents.vb which I thought would only pick up any unhandled exceptions, although it is picking up every exception that happens in my application whether or not they are handled with try catch blocks. Here is my code in applicationevents Private Sub MyApplication_UnhandledException(ByVal _ sender As Object, ByVal e As _ Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) _ Handles Me.UnhandledException e.ExitApplication = _ MessageBox.Show(e.Exception.Message & _ vbCrLf & "The application has encountered a bug, would you like to Continue?", "An Error has occured.", _ MessageBoxButtons.YesNo, _ MessageBoxIcon.Question) _ = DialogResult.No End Sub In the rest of my application I set normal try catch blocks like this: Try Catch ex as exception End Try Can anyone tell me why this is happening?

  • .net load balancing for server

    - by user1439111
    Some time ago I wrote server software which is currently running at it's max. (3k users average). So I decided to rewrite certain parts so I can run the software at another server to balance it's load. I can't simply start another instance of the server since there is some data which has to be available to all users. So I was thinking of creating a small manager and all the servers connect and send their (relevant)data to the manager. But it also got me thinking about another problem. The manager could also reach it's limits which is exactly what i'm trying to prevent in the future. So I would like to know how I could fix this problem. (I have already tried to optimize critical parts of the software but I can't optimize it forever)

  • How to Best Setup a Website Project in VS.NET

    - by Jason
    I have very little experience with setting up a website from scratch in a .NET environment. As I am doing this now, I am wondering - what's the best way to go? Is it better to create a new Website Project, and include the various backend services and database code as part of that project, or is it better to split out the various aspects of the project? If the second, how would I go about doing that? I want to ensure that this project is easy to manage in the future (in terms of source control, deployment, etc), so I want to make sure I'm starting off on the right foot. I was unable to find any tutorials online, but if you have any, I would appreciate those as well. Thanks!
