                                  • We have subclassed the GridView and are trying to set the grid header panels icon at runtime in the view ctor as follows:

                                                    Appearance.HeaderPanel.Options.UseImage = true;
                                                    Appearance.HeaderPanel.Image = DevExpress.Images.ImageResourceCache.Default.GetImage("images/support/info_16x16.png");

                                    This does not work, despite a valid image having been obtained.

                                    I then found your KB article here:  https://www.devexpress.com/support/center/question/details/q314381/image-not-showing-in-grid-header

                                    So tried sinking the CustomDrawColumnHeader event instead. That did work for me for normal grid columns, but it does not fire for the HeaderPanel 'column'

                                    Please advise.

                                  We want to place an icon in the Grid HeaderPanel here:

                                  Because we have it set up to provide a right-click menu:

                                  image004.png
                                  image003.png

                                Hi,

                                Form what I gather, you need to set an icon in the indicator column header. If so, you need to manually draw the required icon in the GridView.CustomDrawRowIndicator event handler. For example:

                                [C#]
                                        private void GridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {            
            if (e.Info.Kind == DevExpress.Utils.Drawing.IndicatorKind.Header)
            {
                e.DefaultDraw();
                e.Handled = true;
                e.Cache.DrawImage(Properties.Resources.InfoIcon, e.Info.Bounds);
            }
        }

                                Please try this approach and let us know your results.

                                  Properties.Resources.InfoIcon does not resolve to anything – however, by replacing it with DevExpress.Images.ImageResourceCache.Default.GetImage("images/support/info_16x16.png") it now works perfectly.

                                  Thanks for the swift response.
