Hi there

I have a C# .NET 4.5.2 WinForms app using the Infragistics UltraWinGrid v16.1.20161.2033 control

It is using a grid with the ViewStyleBand.OutlookGroupBy in play and we are also make use of the UltraGrids built in column chooser via

this.ultraGrid1.DisplayLayout.Override.RowSelectorHeaderStyle = RowSelectorHeaderStyle.ColumnChooserButton;
this.ultraGrid1.DisplayLayout.Override.RowSelectors = DefaultableBoolean.True;

The Column Chooser displays fine when there are columns in the GroupByBox but dissappears when you remove all columns from the GroupByBox i.e when you see the "Drag a column header here to group by that column." text the Column Chooser is no longer available

My question is what is the appropriate technique for always showing the Column Chooser?

Is there a particular event I can use when a column is removed from the GroupByBox that I can use to force the Column Chooser to be displayed?

Thanks in advance

Geoff
