iI want remove CheckBoxes where the Node.Type is 5 or 6. I use this code:
private void TvOne_DrawNode(object sender, DrawTreeNodeEventArgs e) { int type = (e.Node as Node).typ; if (type == 5 || type == 6) { Color backColor, foreColor; if ((e.State & TreeNodeStates.Selected) == TreeNodeStates.Selected) { backColor = SystemColors.Highlight; foreColor = SystemColors.HighlightText; } else if ((e.State & TreeNodeStates.Hot) == TreeNodeStates.Hot) { backColor = SystemColors.HotTrack; foreColor = SystemColors.HighlightText; } else { backColor = e.Node.BackColor; foreColor = e.Node.ForeColor; } using (SolidBrush brush = new SolidBrush(backColor)) { e.Graphics.FillRectangle(brush, e.Node.Bounds); } TextRenderer.DrawText(e.Graphics, e.Node.Text, this.TvOne.Font, e.Node.Bounds, foreColor, backColor); if ((e.State & TreeNodeStates.Focused) == TreeNodeStates.Focused) { ControlPaint.DrawFocusRectangle(e.Graphics, e.Node.Bounds, foreColor, backColor); } foreColor, backColor); e.DrawDefault =} false; ; e.DrawDefault = }false; } else { e.DrawDefault = true; } }
