I have a grid implementing multiple bands, which I used to set RowSelectorHeaderStyle to NONE. But I wanted to allow users to remove/add back columns so I set it to ColumnChooserButton. So the chooser icon appears at the row selector position of the top left corner of the column header row. The problem is the header column row right below the child band will show when the child band is click to expand.
I would like it behave as it was before I set it to ColumnChooserButton, which will always show one header column row at the very top of the grid only.
Never mind, I fixed it. It has nothing to do with the setting of RowSelectorHeaderStyle to ColumnChooserButton.
I just need to set
ultraGridBand1.Override.HeaderPlacement = Infragistics.Win.UltraWinGrid.
HeaderPlacement.OncePerRowIsland;
