When I click on a button in a control it removes all controls in the Panel which I have added dynamically. Can anyone help? int controlID = 0; List<Control> cc = new List<Control>(); ...

I have a WebForms UserControl that is used throughout the site and which contains presentational and business logic, and in particular some 'initizliation' logic (in the Page_Load) My understanding of MVC UerControls is that they have no dedicated controller and thus contain no logic, a...
(New to ASP.NET here.) I have a user control which should check for a value in the request query string before deciding what to render: <%# softLoaded ? "HELLO" : "GOOD BYE" %> This is the code-behind for the user control: public bool softLoaded { get; set; } protected void Page_Load(object sender, EventArgs e) { softLoaded = "...
Hello. I'm trying to split the drawing of a WPF UserControl onto two separate pages of a custom Paged Panel that I'm writing. I thought of using a VisualBrush to draw bits of the control. Is this the way to go? I presume I'll also have to put the controls that need to be visually split in an invisible container. Has anyone come across a...
I'm trying to add some JQuery to an ASP.Net User Control to check to see if checkboxes have been selected or not. It appears that scripting languages are not supported directly in user controls, but need to be added via the RegisterStartupScript() method. I found a post at this url describing this: http://www.codeproject.com/KB/aspnet/...
I have a User Control for typical CRUD like actions on my WinForm app. Validate, Insert, Update, Clear, Cancel, and Delete. On every form I put this on I end up adding the click event, ucPersonNav.btnValidate.Click += new EventHandler(btnValidate_Click);, for every button. What I am wondering is can I have the Events be on the User C...

Walter Rumsby provided a great answer to Where to place JavaScript in an HTML file. He references the work done by the Yahoo Exceptional Performance team and their recommendation to place scripts at the bottom of the page. Which is a hard and fast rule that I've been following for quite sometime now. In the same thread Levi Rosol pointed...
Hi guys, I have a User control (because I use the same in other page, so I thought I should reuse code and not double my work), but in this page I show a list of companies and each one has a company number, I need to pass this company number to that User Control and it has to reload using that passed company number. How can I accomplis...

Hi I've created an ASCX control with a GridView and a DetailsView associated to the GridView, both have a DataSource associated. The ASCX works fine when there's only one in the page, as soon as I add the second one (both with distinct event handlers and parameters) I start having problems with the second control. The first control ke...
The subject line says it all really! I have a user control which can be bound successfully to, say, a Fullname object - i.e. it works ok. I now need to show a list of these and, again, this works ok when the control is in a DataTemplate within ItemsControl.Template. But, the control has a property (InEditMode) that is not a property ...
I have a c# application that is composed of various screens which is each a respective user control. The application requires a lot of switching between the various screens and is also graphic intensive. Each control is disposed once the next control is invoked and the garbage collector is called to release the system resources. The thin...
In reality, I am trying to create a control showing price depths of a stock which needs to accept a large number of messages and summarizing them for display purposes. Will I get a better result if I create it in MFC and use that control in my .Net Winform application than writing the whole thing in .NET? ...
In a normal user control, we have .cs.ascx (code-behind) to assign the namespace we want our control to be in. But what if we don't have this code-behind to assign the namespace? Can we maybe assign the namespace of a user control in the headers? EDIT I was hoping I can do somthing like this: <%@ Control Language="C#" AutoEventWireup="...
I have a web user control (ascx) in my project and I would like to move it to a more general namespace that makes it easier to share the control across projects. The problem is, it seems that web user controls like to stay in a namespace named after the web application they're in. Is there some way to break out of the web app namespace...
