My fault. The
was set to false.
I have created a grid with enable grouping an filtering. Each column has a "google like" filter control as the KB article describes. I have added a reset button (ImageButton) to each filter right from the RadComboBox. The grid, the columns and the RadComboBox property EnableViewState is set to false. When I use a column filter all is working fine. The rest button will be displayed. When I reset the filter by clicking on the rest button the filter will be reseted fine and the reset button disapears as expected.
But when I have set a filter and then I have grouped by drag&drop a column into the group box, the text of the RadComboBox and the CurrentFilterValue are empty and the CurrentFilterFunction is NoFilter and the rest button don't will be shown. And the data is still filtered in the grid.
When I filter by one column and then by a second all is working fine. Only when I group the data the problem occur.
The grid will be used in a webpart in a SharePoint solution.
I'm using Telerik version 2011.2.712.35
Do anyone have a tip?
