I have a textbox control in a column template. When in edit mode (Popup), if I change the value of the text box and while leaving focus on the text box, click on update, the old value of the text box is posted back. If I tab out of the text box then click on update, the new value is posted back.
Is there a setting that I am missing, or has anyone else had this problem.
Our Telerik controls are the latest version.

Jayesh,
The code you supplied works fine. I found that the problem is that I am using template columns, and unless I load the datasource data into the template text box in the ItemDatabound event, is does not display in edit mode. When I do this (load the data to the text box), the same code runs before the ItemCommnd code and thus overwrites the data in the textbox that still has focus with the 'pre-edit' data.
How do I avoid this happening? I need the code to load the data or the text box is blank on edit.

Jayesh,
The code that I have in the item_databound event will load the template controls with data when in edit mode. If not in edit mode, it will load the grid fields. It is this latter operation that is overwriting the data as the databound event fires prior to the itemCommand event.
If I do not load the grid fields when not in edit mode, no data displays in the grid.
I think that I am missing something basic here, but I cannot figure out what it is.

Jayesh,
Given that I have a PopOut edit on my RadGrid row, and this contains three controls plus the Update and Cancel buttons, how does the user get the third control to update correctly when clicking the Update button? The only way that they can get the third field to update is to enter the data, click on the previous field (or any prior field) and then the Update button. This does not seem very intuitive and we have never had to deal with this problem with our other control sets. The currently focused field should blur and update the value when I click the Update button, but this does not appear to be happening. As I stated, it could be that I am missing something basic as this is the first project that we have used the Telerik controls on, but I feel that it should be easier than having to implement javascript events.

I found that I had another RadGrid in my application that worked as expected without the problems that this thread relates to. I changed the RadGrid definition to match the one that worked and it all started working as expected. The only change I made was to remove the following lines from the RadGrid definition :
