Hello,

I am using RadAjax panel for the whole page. I am having listboxes and other labels in my page along with radgrid.

When I move listitem from one listbox to another listbox, I am using radajax panel not to postback.

But after that I see the columns in the RagGrid, 2 of them are disappearing which I am displaying Dynamically.

All other columns are bound columns. What is the reason ?

TIA

Atchut:

When you make the AJAX request to update the listbox controls, you inadvertently appear to also be causing the refresh of the RadGrid which then redraws itself based on the declarative markup, and this loses the columns added from the server-side.

You can follow the approach used in this online demo to fine-tune partial ajaxification of your page:

Ajax/Partial Ajaxification

And, you can reference the Exclude Controls from Ajaxifying documentation for insights.

I hope this helps!
