  • ASP.net repeater, scroll 3 at a time

    - by Christo Fur
    I have a list of data that I need to display in a web page 3 at a time The first needs to be displayed in a div called "left" , the second in a div called "centre" and the third in a div called "right". And I need to be able to scroll through the data with a pager. And so the next 3 results will be displayed in a similar way, and so on till the end of the data set Obviously the alternating templates in the repeater are not suitable for this. Is there a smarter way to achieve this?

  • ASP.NET UserControl not defined?

    - by BryanG
    I've just inherited an app that utilizes usercontrols in a couple ways which I'm not too familiar with. The problem I have right now is that when I attempt to publish this code base, I get a few errors which boil down to where some referenced usercontrols are not defined. Here's an example of one line: Private clientControl As New ASP.usercontrols_clientcontrol_ascx This is a tab strip usercontrol which references other usercontrols to dynamically create the tabs. Now, on the surface I get what is going on here...but the compiler is not accepting this. This tab strip usercontrol is in the root of the project, and the other usercontrols are in a sub folder. error BC30002: Type 'ASP.usercontrols_clientcontrol_ascx' is not defined. I'm sure this is 101 stuff here, but the build works and the publish fails. Any direction would be appreciated.

  • Writing csv file in asp.net

    - by Keith
    Hello, I'm trying to export data to a csv file, as there are chinese characters in the data i had to use unicode.. but after adding the preamble for unicode, the commas are not recognized as delimiters and all data are now written to the first column. I'm not sure what is wrong. Below is my code which i wrote in a .ashx file. DataView priceQuery = (DataView)context.Session["priceQuery"]; String fundName = priceQuery.Table.Rows[0][0].ToString().Trim().Replace(' ', '_'); context.Response.Clear(); context.Response.ClearContent(); context.Response.ClearHeaders(); context.Response.ContentType = "text/csv"; context.Response.ContentEncoding = System.Text.Encoding.Unicode; context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fundName + ".csv"); context.Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble()); String output = fundName + "\n"; output += "Price, Date" + "\n"; foreach (DataRow row in priceQuery.Table.Rows) { string price = row[2].ToString(); string date = ((DateTime)row[1]).ToString("dd-MMM-yy"); output += price + "," + date + "\n"; } context.Response.Write(output);

  • ASP.NET MVC NullReferenceException when inheriting from a Base Controller

    - by rockinthesixstring
    I've got a base controller that I inherit all of my Controllers from. It's job is to basically set caching and error handling as well as check for mobile browsers. My UI works fine, but my Unit Tests are failing. Imports System.Web.Mvc <HandleError()> _ <CompressFilter()> _ <OutputCache(Duration:=30, VaryByParam:="id")> _ Public Class BaseController : Inherits System.Web.Mvc.Controller Protected Overrides Function View(ByVal viewName As String, ByVal masterName As String, ByVal model As Object) As System.Web.Mvc.ViewResult Dim ismobile As Nullable(Of Boolean) = Request.Browser.IsMobileDevice If ismobile Then Return MyBase.View(viewName, "Mobile", model) Else Return MyBase.View(viewName, "Site", model) End If End Function End Class The error I'm getting in my Unit test is on Dim ismobile As Nullable(Of Boolean) = Request.Browser.IsMobileDevice saying Object Reference Not Set To An Instance Of An Object.

  • ASP.NET MVC Viewmodel trouble...

    - by ile
    I've already started similar topic, but still didn't find final solution... So here I am with new one :) ... I'm developing NerdDinner from scratch and now I came to point where I define DinnerViewModel. Following these instructions (starting from Listing 5) I came to this: namespace Nerd.Controllers { // View Model Classes public class DinnerViewModel { public DinnerViewModel(List<Dinner> dinners) { this.Dinners = dinners; } public List<Dinner> Dinners { get; private set; } } public class DinnerController : Controller { private DinnerRepository dinnerRepository = new DinnerRepository(); .... public ActionResult NewDinners() { // Create list of products var dinners = new List<Dinner>(); dinners.Add(new Dinner(/*Something to add*/)); // Return view return View(new DinnerViewModel(dinners)); } } } Also, the Dinner table in this new version of NerdDinner is a bit shortened (it contains of DinnerID, Title, EventDate and Description fields). No matter what I try to add here dinners.Add(new Dinner(/*Something to add*/)); I always get following error Error 1 'Nerd.Model.Dinner' does not contain a constructor that takes '1' arguments C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\Nerd\Nerd\Controllers\DinnerController.cs 150 25 Nerd Because I'm total beginner in C# and generally OOP, I have no idea what to do here... I suppose I need to declare a constructor, but how and where exactly? Thanks, Ile

  • Where has MS Charting gone in .NET 4.0?

    - by zotty
    Forgive me for being a little naive perhaps, but it seems that System.Windows.Controls.DataVisualization.Charting has vanished from VS2010, and blend 4. I'm trying to make a bar graph with a line overlayed, but can't even get started because I can't find the appropriate controls. I know I could use an external graphing package, but I'd like to try the inbuilt controls first.

  • .Net Designer assemblies, C++\C# error

    - by greggorob64
    I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

  • If .net sha1 hash expects a byte array, and php sha1() wants a string, can I match the results?

    - by lynn
    I have a set of bytes I want to apply an sha1 hash to. One hash will be in .net, the other in PHP. Then I'll test to see if they match. In .net, you can create a byte array and use sha.ComputeHash(). byte[] data = new byte[DATA_SIZE]; byte[] result; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data); In PHP, you call sha1($string). I can't do anything about the .net side of the code, but how can I get the same hash out of PHP that .net will generate? Please note: I am ONLY able to work on the PHP side of this. The .net stuff is fixed and can't be modified. Thanks!

  • .Net Remote Log Querying

    - by jlafay
    I have a Win Service that I'm working on that consists of the service, WF Service (using WorkflowServiceHost), a Workflow (WorkflowApplication) that queries/processes data from a SQL Server DB, and a Comm Marshall class that handles data flow between the service and the WF. The WF does a lot of heavy data processing and the original app (early VB6) logged all the processing and displayed the results on the screen of the host machine. Critical events will be committed to eventlog because I strongly believe that should be common practice because admins naturally will look there and because it already has support for remote viewing. The workflow will also need to write logging events as it processes and iterates according to our business logic. Such as: records queried, records returned, processed records, etc. The data is very critical and we need to log actions as they occur. The logs are currently kept as text files on disk and I think that is ok. Ideally I would like to record log events in XML so it's easier to query and because it is less costly than a DB, especially since our DB servers do a lot of heavy processing anyways. Since we are replacing essentially a VB6 application with a robust windows service (taking advantage of WF 4.0), it has been requested that a remote client also be created. It receives callbacks from the service after subscribing to it and being added to a collection of subscribers. Basic statistics and summaries are updated client side after receiving basic monitoring data of what is going on with the service. We would like to also provide a way to provide details when we need to examine what is going on further because this is a long running data processing service and issues need to be addressed immediately. What is the best way to implement some type of query from the client that is sent to the service and returned to the client? Would it be efficient to implement another method to expose on the service and then have that pass that off to some querying class/object to examine the XML files by whichever specification and then return it to the client? That's the main concern. I don't want the service to processing to bottleneck much while this occurs. It seems that WF already auto-magically threads well for the most part but I want to make sure this is the right way to go about it. Any suggestions/recommendations on how to architect and implement a small log querying framework for a remote service would be awesome.

  • How to Select Multiple Records from Multiple Tables at Once - SQL Server/C#/.NET/T-SQL

    - by peace
    I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers. As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record. What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

  • OpenNETCF.Net.Ftp Behaving Flaky

    - by gnomixa
    I tried posting on their boards (authors of this library), however it literally takes months for them to reply when it comes to the free software (can't blame them). But anyways I have found that this library is behaving weirdly - for instance, a major problem with my application is when someone is trying to sign in (through FTP), they provide a correct login and mistype the password, no reply is received from FTP server. I tried doing the same from command window just to verify that it's not the FTP server's fault; and FTP commands were received instantaneously. It almost looks as though this library eats the commands. The same actions often times will yield different results. Can anyone recommend a stable, reliable library to use with Compact framework? Or shed some light on this issue...?

  • a href nested in DIV element in ASP.NET C#

    - by Gal V
    Hello all, My question is quite simple, I created a DIV, with a HyperLink control in it. As following: I created an 'onclick' event in jQuery for the DIV as well: $('#divOne').click(function() { alert('You clicked on the DIV element'); }); My goal is to trigger this event when the DIV area is clicked (working fine), BUT- When the HyperLink is clicked, I need the page to redirect WITHOUT triggering the DIV 'onclick' event (can use JavaScript or jQuery as needed). Thanks all!

  • Would it be faster to use CMS for building the first site in ASP.NET?

    - by rem
    I need an opinion and advise from experienced ASP.NET people, what way to go. Assuming that a developer has some practical background with HTML/JavaScript/PHP on one side and some .NET/C#/WPF experience on the other side. No previous hands on experience with ASP.NET - only theory and some read books on the topic. The task is to build ASP.NET web site with User Managment functionality (user authentication, user account, user buying history, user points and so on) and E-commerce functionality with shopping cart, checkout and all needed for this. Is it worth, i.e. will it be faster, more reliable and secure in the result to use a ASP.NET CMS system (for example Sitefinity from Telerik as declared developer friendly) to build such first site? In what case the learning curve will be more steep and it will take more time to achieve similar results? Notes to take into consideration: 1) Price of the CMS matters not very much 2) E-commerce module should be written from scratch in any case (and integrated in case of using CMS) due to very specific requirements

  • Update Message on ASP.NET ModelPopupExtender

    - by John
    Hi, I have a form in a MS AJAX ModalPopup Extender, which is in a UpdatePanel (for async loading). Everything works as expected. There is one thing that I am trying to do but not sure how to do it. On form submission, there is server side validation on top of client side validation. My question is: what is the best way to display validation error messages if any? It would be ideal if the messages could be written to the popup asynchronously so that the popup is still there. If this is not possible, I am thinking of displaying the messages using the JavaScript alert box. Any insight and suggestions are greatly appreciated. John

  • Capture and handling the tab/Textchanged event in a textbox in asp.net MVC

    - by Icerman
    I have the following code th handle a user name validation on the server side. But the event seems not firing since break points in js or C# code didn't hit. Can anyone point out where I did wrong? Here is the user control which has a user name textbox: <%: Html.TextBox("UserName", Model.Username, new { maxlength = "40", size = "20", tabindex = "1", @onchange = "CheckAvailability()" })% CheckAvailability() is defined in the User.Validation.js and included in the above user control: $(document).ready(function () { function CheckAvailability() { $.post("/Home/Survey/CheckAvailability", { Username: $("#UserName").val() }, function (data) { var myObject = eval('(' + data + ')'); var newid = myObject; if (newid == 0) { $("#usernamelookupresult").html("<font color='green'>Available :-D</font>") } else { $("#usernamelookupresult").html("<font color='red'>Taken :-(</font>") } }); } }); Here is the survey controller function which will have server side validation: [HttpPost] public ActionResult CheckAvailability(string Username) { int Taken = 0; // This is where you add your database lookup if (Username == "abc") { Taken = 1; } return Json(Taken); }
