Filter Error

[Che]

I have three tabs in my grid. I am using filter for my 1st tab and whenever I click the filter I get this error. I tried EnableLinqExpressions="False" , no luck.

Hello Che,

Can you share the RadGrid and RadFilter controls declaration as well as the server-side code you are using? Also specify if the RadGrid and the RadFilter are in the same container.

Sincerely yours,

I will try to get the code by this weekend, for the time being I am sharing the below info

it has 5 tabs and two of them has child rows.
filter works fine for child rows but not for parent row
the only property I used for filter in child row is allowfiltering='true' which is not working for parent row

what do u mean by "specify if the RadGrid and the RadFilter are in the same container"??

Hello Che,

By "specify if the RadGrid and the RadFilter are in the same container" I was asking if the RadGrid and the RadFilter are plaiced in the same parent control, for instance in the same ASP:Panel, PageView, etc.

Are the child rows child tabs or you have hierarchical RadGrid?

All the best,
