hello

I get a NullReferenceException when doing this:

RadDragAndDropManager.SetAllowDrag(this, true);

 


I tried with:

 

RadDragAndDropManager.SetAllowDrop(this, true);

 


This is working fine

I also tried:

this.SetValue(RadDragAndDropManager.AllowDrag,true);

This line crash as well

Does anybody have an idea?

The RadDocking control has properties and methods for working with Tabbed Documents quickly ?
Close/Open etc... Document programmatically.
I would like to perform a LINQ query (or for/foreach) to find the document that implements a particular interface, this is possible?

Example :

private IDebugEditor GetDebugEditor() {  
    var res = from w in radDocking.Documents where w is IDebugEditor select w;  
    if (res.Count() != 0)  
        return (IDebugEditor)res.First();  
    return null;  
}

Hello,

I am using telerik:RadGridView, my Items is set to a DataTable. 

the source Data tableis set to a SQL Query output, data is in a specific dateformat.

In case we setAutoGemerateColumns="true"; the data is displayed only in a modify format (thedata is date and time and the display automatic adds slashes, removes secondsand millisecond)

In the other case(AutoGemerateColumns="false") I have three columns specify and binded to each column;

the results are only visible by row count, the columns data is empty.

appreciate  your advise,

Thank you 

SaritHarel, IAI

I'm obviously having a dumb day, but I can't seem to easily add items to my Outlook bar? I've added the two references to my project, then gone to my toolbox, chosen the RadOutlookbar and then drawn it on to my Window. I get the main part of the Outlook bar, but no items within the component. When I go to Properties, and click on the three dots next to the Items property I get the dialog box appear, but there are no items I can add, and the 'Add' button is grayed out.

Hilp!
