Hello,
I saw the same questions on this forum but they have had not replies so I'm asking the question again.
This is what I get when try to run app with grid:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I set DataSource property from codebehind and data source is a simple dataset.
Any ideas? I use v10.3
Thank you.
Hi,
Thank you for reply.
Now I'm using 2011.1 so problem perhaps somewhere in your code.
As I said previously, your code looked ok to me. Have you tried upgrading to the latest Service Release for 10.3 to see if the issue is resolved there. Or contact Developer Support so they can walk through your sample and attempt to locate the problem.
thanks,Dave
Do you have any news about this problem?
I got the same error in WebDataGrid. Problem starts when I set Hidden property to true on some columns which contain GUIDs. When all columns are visible, everything is ok. Any ideas?
I just tried all this with WebDataGrid and it runs fine. Problem starts when I try to use WebHierarchicalDatagrid
