Hi Alexander,

The window you are referring to is called the ColumnChooser. I don't think it currently supports displaying more than one line of text for each header.

This seems like a bug to me. The ColumnChooser should take on the same settings as the grid so the full caption displays. I'm going to forward this thread over to Infragistics Developer Support so they can writ it up for developer review.

In the mean time, you can probably work around this by explicitly setting the height of the rows in the ColumnChooser. Something like this:

        private void ultraGrid1_BeforeColumnChooserDisplayed(object sender, BeforeColumnChooserDisplayedEventArgs e)
        {            
            // Hook into the column chooser events. 
            UltraGrid columnChooserGrid = (UltraGrid)e.Dialog.ColumnChooserControl.Controls[0];
            columnChooserGrid.InitializeRow += new InitializeRowEventHandler(columnChooserGrid_InitializeRow);
            e.Dialog.FormClosed += new FormClosedEventHandler(columnChooserDialog_FormClosed);
        }

        void columnChooserDialog_FormClosed(object sender, FormClosedEventArgs e)
        {
            // Unhook from the column chooser events. 
            ColumnChooserDialog columnChooserDialog = (ColumnChooserDialog)sender;
            columnChooserDialog.FormClosed -= new FormClosedEventHandler(columnChooserDialog_FormClosed);
            
            UltraGrid grid = columnChooserDialog.ColumnChooserControl.Controls[0] as UltraGrid;   
            grid.InitializeRow -= new InitializeRowEventHandler(columnChooserGrid_InitializeRow);
        }

        void columnChooserGrid_InitializeRow(object sender, InitializeRowEventArgs e)
        {            
            e.Row.Height = 50;
        }
