Control: TreeViewAdv |

Customize the node background

This can be done by customizing the node background in the NodeBackGroundPaint event.

C#

private void treeViewAdv1_BeforeNodePaint(object sender, Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintEventArgs e)
{
   e.Active=false;
}
private void treeViewAdv1_NodeBackgroundPaint(object sender, Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintBackgroundEventArgs e)
{
   Pen p=new Pen(Color.Red);
   p.DashStyle=DashStyle.Dot;
   if(this.treeViewAdv1.Nodes[0]!=e.Node)
   {
      if(e.Selected)
      {
         // Draw the beige background.
         e.Graphics.FillRectangle(new SolidBrush(Color.RosyBrown), e.Bounds);
         e.Graphics.DrawRectangle(p,e.Bounds);
      }
   }
   else
   {
      if(e.Selected)
      {
         e.Graphics.FillRectangle(new SolidBrush(Color.RosyBrown), e.Node.TextBounds);
         e.Graphics.DrawRectangle(p,e.Node.TextBounds);
      }
   }
   e.Handled = true;
}

VB

Private Sub treeViewAdv1_BeforeNodePaint(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintEventArgs)
   e.Active=False
End Sub
Private Sub treeViewAdv1_NodeBackgroundPaint(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintBackgroundEventArgs)
   Dim p As Pen = New Pen(Color.Red)
   p.DashStyle=DashStyle.Dot
   If Me.treeViewAdv1.Nodes(0)<> e.Node Then
      If e.Selected Then
         ' Draw the beige background.
         e.Graphics.FillRectangle(New SolidBrush(Color.RosyBrown), e.Bounds)
         e.Graphics.DrawRectangle(p,e.Bounds)
      End If
   Else
       If e.Selected Then
          e.Graphics.FillRectangle(New SolidBrush(Color.RosyBrown), e.Node.TextBounds)
          e.Graphics.DrawRectangle(p,e.Node.TextBounds)
       End If
   End If
   e.Handled = True
End Sub
