WinForms Grid - How to Custom Draw Footer Cells.

Example

The example shows how you can perform custom painting of footer cells with the GridView.CustomDrawFooterCell event.

C#

using DevExpress.XtraGrid.Views.Grid;
using DevExpress.Utils.Drawing;

private void gridView1_CustomDrawFooterCell(object sender, FooterCellCustomDrawEventArgs e) {
    int dx = e.Bounds.Height;
    Brush brush = e.Cache.GetGradientBrush(e.Bounds, Color.Wheat, Color.FloralWhite,
      LinearGradientMode.Vertical);
    Rectangle r = e.Bounds;
    //Draw a 3D border
    BorderPainter painter = BorderHelper.GetPainter(DevExpress.XtraEditors.Controls.BorderStyles.Style3D);
    AppearanceObject borderAppearance = new AppearanceObject(e.Appearance);
    borderAppearance.BorderColor = Color.DarkGray;
    painter.DrawObject(new BorderObjectInfoArgs(e.Cache, borderAppearance, r));
    //Fill the inner region of the cell
    r.Inflate(-1, -1);
    e.Cache.FillRectangle(brush, r);
    //Draw a summary value
    r.Inflate(-2, 0);
    e.Appearance.DrawString(e.Cache, e.Info.DisplayText, r);
    //Prevent default drawing of the cell
    e.Handled = true;
}

VB.NET

Imports System.Drawing.Drawing2D
Imports DevExpress.XtraGrid.Views.Grid

Private Sub GridView1_CustomDrawFooterCell(ByVal sender As Object, _
ByVal e As FooterCellCustomDrawEventArgs) Handles GridView1.CustomDrawFooterCell
    Dim dx As Integer = e.Bounds.Height
    Dim brush As Brush = e.Cache.GetGradientBrush(e.Bounds, Color.Wheat, Color.FloralWhite, LinearGradientMode.Vertical)
    Dim r As Rectangle = e.Bounds
    'Draw a 3D border
    BorderPainter painter = BorderHelper.GetPainter(DevExpress.XtraEditors.Controls.BorderStyles.Style3D)
    Dim borderAppearance As AppearanceObject = New AppearanceObject(e.Appearance)
    borderAppearance.BorderColor = Color.DarkGray
    painter.DrawObject(new BorderObjectInfoArgs(e.Cache, borderAppearance, r))
    'Fill the inner region of the cell
    r.Inflate(-1, -1)
    e.Cache.FillRectangle(brush, r)
    'Draw a summary value
    r.Inflate(-2, 0)
    e.Appearance.DrawString(e.Cache, e.Info.DisplayText, r)
    'Prevent default drawing of the cell
    e.Handled = True
End Sub
