how can i change the background color of a gridTemplate Header.

thanks

andré

which may be why collapseAll doesn't work.
i give the command collapseAll after filling the grid but all subgrids are still visible.

            this.dgvOrder.Templates.Add(dgvOperationTemplate);
            dgvOperationTemplate.DataSource = Sql.Dashboard_listOperationHierarchy();

            // layout
            dgvOperationTemplate.ReadOnly = true;
            dgvOperationTemplate.ShowRowHeaderColumn = false;
            //templateOperation.AutoScroll = true;
            dgvOperationTemplate.MasterTemplate.AutoGenerateColumns = true;
            dgvOperationTemplate.MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None;
            dgvOperationTemplate.BestFitColumns(BestFitColumnMode.AllCells);

            GridViewRelation reletionOrderOperation = new GridViewRelation(dgvOrder.MasterTemplate, dgvOperationTemplate) { RelationName = "OrderOperation" };
            reletionOrderOperation.ParentColumnNames.Add(ColumnTitle.GridOrder.WNNr);
            reletionOrderOperation.ChildColumnNames.Add(ColumnTitle.GridOperation.WNNr);
            this.dgvOrder.Relations.Add(reletionOrderOperation);

            dgvOperationTemplate.CollapseAll();
            dgvOperationTemplate.CollapseAllGroups();

Hi, 

I've tried many things to display the 1st row top cell border in a gridview when ShowColumnHeader is set to false (like screenshot).

Do you have an idea pls ?

Thanks

I've got a RadSplitButton setup on a ribbon.  Initially when clicking I'd always get the dropdown menu regardless of where I was clicking.  Then I read you have to set the DefaultItem property which I did like this:

btnTest.DefaultItem = btnTest.ActionButton

This works great...except now the UI stops updating the button when the mouse is clicked.  The entire button turns white when you mouse over and remains white as you click (on either the Action Button or the Arrow Button)

BTW I'm using VisualStudio2012LightTheme.

Can you explain how to correct this?

Thank you!

I have used this code to generate barcode to excel.   I tried Code 39 and EAN128.  But the barcode scanner cannot read.  What is missing in here?  Where can I find demo & documentation for winform barcode to excel?  Thanks.

                Telerik.WinControls.UI.Barcode.Symbology.EAN128 code39Extended1 = new Telerik.WinControls.UI.Barcode.Symbology.EAN128();
                RadBarcode rBL = new RadBarcode();
                rBL.Symbology = code39Extended1;
                rBL.Value = "EE4698";
                rBL.LoadElementTree();
                Image imgBL = rBL.ExportToImage();
                imgBL.Save("c:\\temp\\img.jpg");

                oSheet.Cells[1, 1] = "EE4698";
                oSheet.Shapes.AddPicture("c:\\temp\\img.jpg", MsoTriState.msoFalse, MsoTriState.msoCTrue, 50, 50, 300, 45);
