Hi,

I use the following code to set the columnchooser visible.

this.ultraGrid1.DisplayLayout.Override.RowSelectorHeaderStyle = Infragistics.Win.UltraWinGrid.RowSelectorHeaderStyle.ColumnChooserButton;
            this.ultraGrid1.DisplayLayout.Override.RowSelectorNumberStyle = Infragistics.Win.UltraWinGrid.RowSelectorNumberStyle.RowIndex;
            this.ultraGrid1.DisplayLayout.Override.RowSelectors = Infragistics.Win.DefaultableBoolean.True;

When i set all the columns invisible, the columnchooser button disappeared. Once I closed the column chooser dialog, I could not reset the columns to visible.

I found that when I set the ultraGridBand1.RowLayoutStyle property(whether RowLayoutStyle.ColumnLayout or RowLayoutStyle.GroupLayout), the columnchooser button disappeared.

But when I set  RowLayoutStyle property to RowLayoutStyle.None or just use the default setting, the columnchooser button didn't disappear.

The problem is that unless I set the RowLayoutStyle property, I cannot design complex column header.

Is there any way to keep the columnchooser button visible, when I set  RowLayoutStyle to ColumnLayout and all the columns invisible?

Thanks in advance.
