OK, Mike,

I have solved the problem.

I got some thinkings from other posts and wrote simliar code in my project.

Infragistics.Win.UltraWinGrid.Resources.Customizer.SetCustomizedString("ColumnChooserButtonToolTip", ".......")

So, thanks all the same.

Hi Mike,

I encountered the same problem and wanted to change the tooltiptext as well.

However, where could I find the ResourceStrings, please tell me with the detailed instructions.

Or ,could you tell me what event will be handlered when I click the RowSelectorHeader region except that RowSelectorHeaderStyle is set to ColumnChooseButton.

Hi

sorry about not responding so long, thanks for the answer - yes was talking about that button and i thing your suggestion will be very helpfull :)

Thanks
