Getting Error on Postback
posted

Whenever my page posts back, I am getting the following error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I did a search for this and found a post here about hidden columns but I don't have any hidden columns.  I am also not using any <%...%> items on the grid anywhere.

Any idea what would be causing this??

    Hello Gary,

    I have created a support ticket with the following number :CAS-55298-N6P0TV . Could you post me your grid markup here please? Do you have WebDropDown editor  provider in the grid?

    Thanks.
