DataAnnotation on multiple user controls displaying on wrong control


I have a table that displays a user control on each row. The user controls are strongly typed to a viewmodel which contains DataAnnotation style validation. If one of the rows has invalid data entered (lets say the 3rd row) the data annotation validates display agains the first row/user control.

How do I get the data annotation to show against the relevant user control?

I'd post a pic to show what I mean except it will not display it!.:/

SPSWC:ProfilePropertyValue and multiple values user properties


Hi, I'm trying to customize the profile.aspx page in My Profile (SP 2010). All works fine except for the fact that I can't see the values of the user properties configured as multiple-value fields.

I'm using spswc:ProfilePropertyValue and what I get is a list of value separator (comma or semicolon, as configured in the user property) without values.

Do you know how to display multiple value user properties?

Thank you

Problem with having multiple user controls in 1 app


I have some problems with User Controls when they are used in conjunction with TabControl bound to a ICollectionView (from a ObservableCollection<TabViewModel>). The UserControls all seem to act as 1 and content I enter in 1 will also appear in other UserControls.

Suppose I have TabViewModel, a simple class with properties for Tab Title and Content

public class TabViewModel : ObservableObject
  protected string _tabTitle;
  protected string _text; 

  public string TabTitle {
    get { return _tabTitle; }
      _tabTitle = value;
  public string Text {
    get { return _text; }
      _text = value;

Multiple Instances of User Control


I have a user control that I place on a page severl times.  When I make a selection on a ddl in one one control the SelectedIndexChanged event fires for all the control on the page for that ddl.  So I get duplication of an insert that I do.  Is there a way to make sure these events are isolated so this doesn't happen.


UI Datepicker and web user controls



I have developed an application using the Master-Detail pattern described in this Matt Berseth article.

The only difference between Matt's article and me is that I am using a FormView object in place of a DetailsView.

Everything works fine except that the formview object, in my case it's inside a user control and I can't figure out how to use the jquery datepicker UI plugin.

I have tried to put the script block for the datepicker either in the aspx page as well as inside the user control but in both cases the calendar does not come up when the related textbox get the focus.

Any suggestion on how to work with the datepicker inside an ascx?

thanks in advance!

Advanced Basics: Adding New Features with User Controls


In past versions of Visual Basic, there were rudimentary graphics controls. In Visual Basic .NET you have the GDI+ library, which enables you to draw lines, circles, and most anything else. But how can you use the functionality of GDI+ to create lines and other graphics that respond to user mouse clicks and events? Find out.

Windows Forms: Developing Compelling User Controls that Target Forms in the .NET Framework


In the beginning, writing controls meant dealing with Windows messages. Then came Visual Basic controls, which introduced methods, properties, and events. Later, ActiveX controls, which ran atop COM, became popular. While each innovation in control writing brought more flexibility, nothing has matched the versatility of the new .NET Windows Forms controls and Web Forms controls. This article, the first of a two-part series, introduces the reader to Windows Forms, beginning with their inheritance from one of the .NET CLR base classes, which makes control creation much faster than before. Control programming is illustrated through the development of a login control. The equally flexible Web Forms controls will be covered in Part 2.

asynchronous loading user controls


I have 3 user controls that I have to load at the same time.  They each contain a gridview that pulls data from the database.  They are doing a "delay" load of the data so there is a progress bar template that shows that the data is loading however the first gridview fires and loads, then the second, then the third and I need them to all fire at the same time.  Any ideas? 

User Controls and Control Extenders


Two separate questions, but sufficiently intertwined that I'm going to try the two together....

Firstly - User Controls and Behaviours

I have a User Control which contains a few visual controls.  I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences.  That is all rock solid and working well.  However, when developing, I did discover that I couldn't attach the behaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control.  So, I have attached my behaviours to a "random" TextBox within the User Control. 

So - first question, is there a better way to do that?  For example, should I always be rendering a SPAN as an element to surround the control?  Not sure what that would do to the robustness of the rendering.  What is the right way to attach a behaviour to a User Control.

Secondly - Accessing those same Behaviours later

Assume I have placed a User Control on the page.  That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour).
