Would it be possible to explain this a bit further?
I am looking into the item template example here
but I was hoping to find an example where the user's double-click is captured, the label goes into some sort of 'edit' mode, and then when the label loses focus it moves back out of 'edit' mode.
The way I could think of doing this seems really complicated, though. It would be having two controls on every tab, one a text box and the other a label. The text box is initially set to visible=false, and the label set to visible=true. I would capture the label's double-click event and toggle the two control's visibility. This would then allow the user to enter a new name of the label. When the text box loses focus it toggles each controls visibility again.
Like I said, though, I am positive I saw an example of this functionality somewhere on the ASP.NET portion of the Telerik website. I've gone through a ton of the examples trying to find it again, but haven't been successful.
