The Gridview Distinct Filters can't be reuse if the filtering panel is close.

When the filter panel is reopen selecting or deselecting distinct filter have no effect.

This is reproductible in telerik demo in any gridview with distinct filter.

the bug is present in browser and oob applications.

In addition the AutoExpandGroups="False" is not respected and it only occurs when the GroupRenderMode is set to "Nested". As a workaround you can set the GroupRenderMode to "Flat".

can you please expose when key enter is pressed on a grid? you're too selfish to just hid it for yourself! why do you make things so complicated for us??
