I am running Telerik controls file version 1010.1.415.20.
In the NeedDataSource on my RadGrid, I am reformatting the FilterExpression to apply a Null filter. However, the Null filter is not being applied. Instead, I get all records from my DataSet (which is a generic list). Is the Null filtering broken in the version of the Telerik controls I am running?

Hi Sean,
Please, try replacing the FilterExpression in the ItemCommand event handler of RadGrid, as shown in Example 2 of this help article and see if it solves the issue on your side:
Custom option for filtering

Tsvetina,
My code does replace the filter expression with my own, but the isnull filter expression does not appear to work. I'm creating a filter expression of "([RelatesTo] == null)". The datasource for my grid is a generic list.

Hello Sean,
There might be a mistake in the filter expression syntax. The easiest way to check would be if you use the built-in filtering of the grid to create a IS NULL filter expression and compare it to yours. Have you already prepared this check? Also, have you set EnableLinqExpressions="false"?

Tsvetina,
I do not have EnableLinqExpressions="false". I plan to see how the built-in filtering formats an "is null" search expression and rework my search to match. I'll post again if I don't have any luck fixing this. Thanks.
