I have a grid that has been 'styled' where the column header background color is not 'default'. When I display the ColumnChooser the Header background is 'default' but the text color is from my 'style' (white). Due to this behavior the end users cannot read the columns (white on light grey). I have attempted to set the appearance in the BeforeColumnChooserDisplayed event with no luck.
Also, the column chooser seems to be ignoring the 'excludeFromColumnChooser' property.
Using 7.1
Answered my own questions I guess.
Issue 1: DisplayLayout.Override.HeaderStyle must not be 'Default' in order for the Chooser to style itself to the source grid.
Issue 2: Columns ignoring the ExcludeFromColumnChooser property.
Resolution: If you selected 'SingleBandSupport for MultipleBandSupport you MUST set CurrentBand.
Well, I too having the same problem with ExcludeFromColumnChooser property. Could you let me know the code on exactly what you did.
Resolved the issue. Thanks
