I am using a asp.net TextBox control inside GridTemplateColumn and OnTextChanged event capuring the text entered by user.
save in memory and bind it back to the RadGrid onItemDataBound.
But after the Grid binds and shows up on screen. I cannot type in textbox control of any row and cannot type in the filter boxes, Radgrid is freezing.
It works after I click the mouse outside the grid and click on filter box or grid template textbox.

Please let me know, if any issues.
Appreciate your quick response on this.

As I just wrote in your support ticket, I am unable to replicate the problem on my side, using parts of your code. Can you please review the ticket reply and the attached project and post there what are your comments on my replication steps?

Is the issue resolved? I have a similar issue where in the RadGrid's search textbox on the column filter freezes after 2 attempts on the same column and does not allow the user to change the search or type in other serch textboxes.
Iam using telerik:RadGrid -> telerik:GridBoundColumn and DataField is set.
This is happening in IE8.
Quick reply on this is highly appreciated.
Thanks & Regards

As my colleague Tsvetina previously mentioned we were not able to replicate similar issue on our side. Could you please open a regular support ticket and send us runnable version of your application which demonstrates the problem you are facing? Thus we will be bale to debug it locally and advise you further.
Also in case you are ajaxifying your RadGrid control with RadAjaxManager or RadAjaxPanel please set RequestQueueSize property for the ajax control to a value grater than 1 and verify if this makes any difference.
