Details table expand causes Main table color styling to disappear

[Chris]

I have a RadGrid with one Details table.  I have code-behind (ItemDataBound) that sets column colors based on data from the database.  Works great.

When expanding a Details table in any one row, the color styling in the Main table disappears.

Please see attached for a visual example.

Hello Chris,

The reason for that behavior is that the grid does call ItemDataBound event handler when expand/collapse command is fired and and in this case the applied styles are lost. A possible solution is to manually loop through all items on PreRender event handler and apply a styles to each item. For your convenience I prepared a small runnable sample and attached it to this thread.

Regards,

That did it, Kostadin.  I had forgotten about the ItemDatabound not firing for the main table when expanding a details table.  Your solution works perfectly.  Thank you very much!
