RadGrid Filter shows tiny empty box

[David]

I am attempting to enable the filtering on a radrid.  I have the MasterTableView.AllowFilteringByColumn set to true.  When I run the application I get no errors, but when I click on the filter icon next to each Column I get a tiny empty box about the size of a checkbox.  The filter does not appear.

Hello David,

I tried to reproduce the described issue but to no avail. I am sending you a simple example which shows that the filtering menu is works as expected. Could you please check it out and let me know what differs in your case.
Also at t meantime could you please verify that you do not have any custom css style which forces the menu to be shown as tiny line?

Looking forward for your reply.

I have looked at the example, but have not resolved my issue.  I have learned since my last post that I need to have events for the NeedDataSource and FilterCheckListItemsRequested since I am trying to use the CheckList filter.  The NeedDataSource events fires, but when I click on the FilterCheckListItemsRequested it never fires and I get the box that is in the attached screenshot.

Hello David,

The described issue is very strange and we have not encounter it so far and we are not sure what could be the reason for it. I tried to reproduce it on my side, but to no avail. Could you please post the RadGrid declaration with the related code behind? Also at e meantime could you please verify that you assign data source to the e.ListBox control into the FilterCheckListItemsRequested event and call DataBind() method as is shown into the following online documentation article:

Looking forward for your reply.

Not to butt in here, but I'm currently working on the same thing and I've encountered this when you're DataColumns are not marked with the "FilterCheckListEnableLoadOnDemand = true" attribute.

Thank you Erik, that solution worked for me

No problem, glad it worked.  Hopefully you can filter on more then one checkbox as in my case if I select more then one checkbox it ignores them and simply displays everything, but if I select just one checkbox it filters fine....

Just created my account to Thank you, it really saved me a day. 

Note: Surprised that Telerik engineers aren't aware of this issue. This step should be part of the tutorials on the site.

 Thanks.

Thanks Sohail.... I'm glad it helped someone else as well.
