For a long time now I've used a dependable Javascript function to preselect the text in a textbox.  However I discovered today that when a textbox resides in an AJAXifield RadWindow, a more complex approach has to be used.  Here's the code showing both approaches:


I'm wondering if there's a way to test for whether the textbox sits within a RadWindow?  If so, then I could just call one function and let it decide which approach to use.

Sincerely,

Hi Robert,

I assume your textbox is in the ContentTemplate of a RadWindow. If this is the case then it acts like any other container - you can check, for example for its parent elements, yet this is an unsafe approach for a common function - you cannot be always certain what the page's layout would be.

The approach when you use the Sys.Application.Load event to make sure the response is received would also be applicable for a regular postback, so you can leave only this function.

Alternatively, you can create two functions - one to use with AJAX and one - with your current approach for the rest of the scenarios.

Marin,

You wrote: "The approach when you use the Sys.Application.Load event to make sure the response is received would also be applicable for a regular postback, so you can leave only this function."

I would have thought that too but I tested the Sys.Application only version on a page where the controls were not in a RadWindow.  It didn't work.

Marin,

My apologies for the delay in getting back to you.

In any case, your solution works perfectly in both RadWindow and non-RadWindow containers.  I'm really not sure why the approach didn't seem to be working for me before. But all is good now!

Robert
