Hi Team,
I have a peculiar problem and I am not sure if anyone had come across this problem earlier. however the issue goes like this..
I have a grid with combination of TemplateColumns and BoundColumns and when I filter the grid using the filters under template columns I can see the results in UI (grid) but when I do the same in BoundColumns I do not see any results.. !!!
Funny thing is I can see the output from the query and its returns the correct number of results from DB. and its also assigned to the GridDataSource in the NeedDataSource event. however I cannot find the GridDataItem in the ItemDataBoundItem, I can fetch only headeritem, filteritem and footeritem.
It shows "No records to display" even when there are lot of records assigned to the DataSource.
Here I am attaching the screenshot, where you can see that the records count is displayed but not the records.. !!
Any help is highly appreciated.
Thanks,
Preetham.

Hello Preetham,
I have created a sample RadGrid web site to test the described behavior. On my side everything works as expected and the GridBoundColumns are being successfully filtered as well as any other column. Please check out the attached application and try to distinguish the crucial differences between our projects.
Kind regards,

Hi Eyup,
Thanks for the investing some time on this query and creating a sample code for me, really appreciate it.
However, I have been using Telerik Grids from a long time and also a created many of them with both TemplateColumns and Bound Columns and all of them work fine while filtering and sorting and pagination as well, but I have never come across this kind of issue where in the filtering fails only when we do it on a BoundColumn.
Actually we are not using Template and Bound columns directly in our application,here we are creating more classes that inherit from them as per our requirement and all of the grid work fine but this particular scenario
Here we have the grid inside a RadAjaxPanel if that makes any difference?
Here I am adding the code snippet also if it helps in solving this issue.
and the server code goes like this
and the skin id

Hello Preetham,
Please note that custom created controls are not supported even if they are inherited directly from RadControls. Therefore, you will need to review your specific implementation logic since the case is out-of-scope for our support team.
We will be glad if we could help on issues related with the use of RadControls in a direct manner.
All the best,
Eyup

Hi Eyup,
Thanks for the reply, anyhow I could find the solution for the issue and we have fixed it..at first we changed all of the columns to TemplateColumns instead of BoundColumns but the issue was we were not clearing the filtervalue in the mastertable
Here is the fix,
adding this line
m_UIListingGrid.MasterTableView.FilterExpression = string.Empty;
in the NeedDataSource did the trick
Mark this as an answer.
