Dynamic Grid inside a FormView Item Template

[Payal Mandalia]

Hi all,

I have been using RadControls for a while now and I really like them.But this dynamic Grid creation is driving me crazy.

Basically I have a page to generate dynamic reports and I am using Radgrid in a FormView to view report.
I have my grid statically declared in the markup and I create the mastertableview columns and detailtableview columns at runtime from code behind and it can have as many hierarchy level the user wants.The hierarchy mode is ServerBind.
I create the structure and properties on PageLoad.

Now the problem I am facing is I am not able to expand the detailtableview and cant navigate to the next page of the grid..
I have tried everyhting possible but cant figure wht the problem is??/
If anyone could help me with this issue it would be great...

The error im getting is : System.Data.SyntaxErrorException: Syntax error: Missing operand before 'Is' operator.
The stack trace looks like this:

Hello Payal,

I reviewed the setup, and the code seems correct.
If the issue persists, you can open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior. We will debug it locally, and get back to you with more information on the matter.

All the best,
Yavor

Hi Yavor,

Thanks for your reply.
I have worked my way around to this problem and now have my code working the way I wanted it to be .
The only thing I changed in my code is I removed the parent table relations and it works fine now..
I would also like to let  you and your team know that I like using RadControls and I think they are great , very helpful and handy.
Keep up your good work.

Thanks a lot for your support.
Payal Mandalia.
