I want to add an image on a grid over a row. I want to keep my background image appearance on the others rows following and preceding the selected row. The cells where the image has been added must stay editable. Some cells are comboboxes and others are textboxes. I''ve tried that without result: Dim style As GridStyleInfo Dim grid As GridControl = Me.grid style = grid(Me.grid.CurrentCell.RowIndex, 2) grid.BanneredRanges.Add(GridRangeInfo.FromTlhw(Me.grid.CurrentCell.RowIndex, 2, 1, 5)) style.BackgroundImage = GetImage("img.jpg") style.BackgroundImageMode = GridBackgroundImageMode.StretchImage style = grid(Me.grid.CurrentCell.RowIndex, 2) style = Nothing grid = Nothing AND this with the same result : grid.FloatCellsMode = GridFloatCellsMode.OnDemandCalculation grid.CoveredRanges.Add(GridRangeInfo.Cells(Me.grid.CurrentCell.RowIndex, 2, Me.grid.CurrentCell.RowIndex, 6)) grid(Me.grid.CurrentCell.RowIndex, 2).BackgroundImage = GetImage("img.jpg") grid(Me.grid.CurrentCell.RowIndex, 2).BackgroundImageMode = GridBackgroundImageMode.StretchImage I''m out of ideas. And I didn''t found something that could help me in the samples. Thank you.

You want to set the background of a row to a particular bitmap, is that correct? Take a look at the Grid\Samples\Quick Start\BannerCells sample. It shows how you can set the background of a range of cells to a bitmap using BanneredRanges.

Yeah, but I would like, for example, to put a gradiant bar (one row) in the middle of the essential grid box. Here is a picture attached of what I''m looking for. box_7101.zip

You could try handling the grid''s paint event and do the drawing there yourself.
Private Sub gridControl1_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles gridControl1.Paint
            Dim range As GridRangeInfo = GridRangeInfo.Cells(11, 2, 11, 5)
            Dim rect As Rectangle = Me.gridControl1.RangeInfoToRectangle(range)
            If rect.IntersectsWith(e.ClipRectangle) Then
                Dim br As New System.Drawing.Drawing2D.LinearGradientBrush(rect, Color.FromArgb(200, Color.Black), Color.FromArgb(100, Color.White), Drawing2D.LinearGradientMode.Horizontal)
                e.Graphics.FillRectangle(br, rect)
            End If
End Sub
