C-Sharp (C#) Group: Treeview Node Selection : Show arrow instead of highlighting

Hi
Got a doubt.
In C# Treeview on selecting a node its backcolor changes to
blue (i.e
it turns blue and gets selected)
Now i want to override this property and show an arrow
instead of the
blue color for the selcted node.
Please let me how this can be done. 

Regards,
Gouri K.

Hi Gouri,

You'll have to override the DrawNode event of the TreeView
like this:

TreeView view;

private void setUpCustomDraw() {
	// The TreeView will still take care of drawing the lines,
pluses,
minuses, etc...
	view.DrawMode = TreeViewDrawMode.OwnerDrawText;
	view.DrawNode += new
DrawTreeNodeEventHandler(view_DrawNode);
}

void view_DrawNode(object sender, DrawTreeNodeEventArgs e) {
	Graphics g = e.Graphics;
	TreeNode node = e.Node;
	int arrowWidth = 10;
	g.DrawString(node.Text, view.Font, Brushes.Black,
e.Bounds.X +
arrowWidth + 2, e.Bounds.Y);
	if(e.State == TreeNodeStates.Selected) {
		// Draw arrow
		Point[] p = new Point[3];
		p[0] = new Point(e.Bounds.Left, e.Bounds.Top + 2);
		p[1] = new Point(e.Bounds.Left, e.Bounds.Bottom - 2);
		p[2] = new Point(e.Bounds.Left + arrowWidth, (e.Bounds.Top
+
e.Bounds.Bottom) / 2);
		g.FillPolygon(Brushes.Black, p);
	}
}

I haven't tested it but the code should look a lot like
this 

Cheers,
Bram Fokke
