One of them is a custom class containing all UI Strings, the other a OpenFileDialog: class MyControl: Control { // ... private OpenFileDialog m_dlgOpen = new OpenFileDialog(); public OpenFileDialog DialogOpen { get { return m_dlgOpen; } } } Thi...

I'm building a custom control in Silverlight by deriving from ContentControl and doing some special formatting to put a dropshadow behind the contents. I've nearly got it working but have recently ran into a bizarre error. It works fine if it contains anything besides a Border, or a Grid/Stackpanel/etc that does not have an explicitl...
There is a program with a long list, from which I would like to take screen shots from. The Problem is, that there are only 14 of about 100 shown. How can I take a screen shot of the entire list? The one approach that comes to my mind is basically send a PG-Down click to this list, take a new screen shot and merge them together. Are the...
This is partly in reference to this: http://stackoverflow.com/questions/485390/why-isnt-the-selectedindexchanged-event-firing-from-a-dropdownlist-in-a-gridview/641715#641715 I thought it different enough to ask another question. My thought is that instead of adding a dropdownlist (ddl) to a gridview and then using the technique above ...
I need a way to for a custom control (descended from TCustomControl) to tell if it is currently visible. I'm not talking about the .Visible property; I mean whether or not it's actually being displayed on-screen at the moment. Does anyone know how to do this? ...

I could probably put them in the the web.config of the application where I'm using the control, but that seems a bit messy to me. What should I be doing? EDIT: The configuration data will typi...

Basically, what I'm trying to create is something akin to the infamous 'Coda Slider' but i just don't know enough to get started properly. Can anyone either point me i...

To give a concrete example, say i have a property called 'Title' which i can set using property syntax like this - <local:myControl Title="the title"/> But the...
I know that it is possible to define custom tags in ASP.NET with User Controls. But as far as I know you can only add attributes to these controls. I would like to be able to embed more complex data, a bit lite this: <myControls:MyGraph id="myGraph1" runat="server"> <colors> <color>#abcdef</color> <color>#123456</color> ...

Hello! I have such task - to create control that union two controls (DataGrid from WPFToolkit and standard Toolbar). On a large scale, it doesn't matter what particular controls it unions, I need to find out the common practices that can be used to build what I need.

The generated HTML code for my custom ASP.net server control generates the name attribute for child controls, instead of the id attribute. Something like this : <span id="GridView2_ctl02_editdis"> <input type="text" name="GridView2$ctl02$editdis$ctl00"/> </span> The ID for the custom control itself is apparently proper. What is e...
