Hello TheLostLeaf,

Currently there is no easy way to do that.

We have a plan to add a special "x" button on the right of the filter editor, i.e. the text-box. This "x" will assign null as the value, since there is no other easy way to enter null in a text-box. This will look like just the "Search Programs and Filter" text box when you click the Windows7 Start Button.

What do you think? Will this be the best approach? In case you have some ideas on how to implement filtering by null from the UI, could you please share them with us and we will log them.

Thanks in advance.

Sincerely yours,
Ross

Thanks for the quick reply. I currently develop with RadAjax, WinControls, Reporting, and WPF. The way you have null filtering in the WinControl grid is perfect just select IsNull or IsNotNull.

I develop for large government projects and in reporting they always want to filter null fields. I intergrated telerik reporting with a popup radgrid that allows to you filter data then apply it to the report.

Note: my workaround in WPF grid was to temporarily populate the null fields with the word 'null' then remove them before applying to report. This allowed for filtering on the text.

Thanks for all of your great efforts and products ! They make me shine with my clients.
