winform treeview 选择整行后，选择的默认颜色如何更改呢

Question

如题所述

Answer 1

您好，您试试这样：
public FrmMain()
{
InitializeComponent();
treeView1.HideSelection = False;
//自已绘制
this.treeView1.DrawMode = TreeViewDrawMode.OwnerDrawText;
this.treeView1.DrawNode += new DrawTreeNodeEventHandler(treeView1_DrawNode);
}

//在绘制节点事件中，按自已想的绘制
private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e)
{
e.DrawDefault = true; //我这里用默认颜色即可，只需要在TreeView失去焦点时选中节点仍然突显
return;

if ((e.State & TreeNodeStates.Selected) != 0)
{
//演示为绿底白字
e.Graphics.FillRectangle(Brushes.DarkBlue, e.Node.Bounds);

Font nodeFont = e.Node.NodeFont;
if (nodeFont == null) nodeFont = ((TreeView)sender).Font;
e.Graphics.DrawString(e.Node.Text, nodeFont, Brushes.White,Rectangle.Inflate(e.Bounds, 2, 0));
}
else
{
e.DrawDefault = true;
}

if ((e.State & TreeNodeStates.Focused) != 0)
{
using (Pen focusPen = new Pen(Color.Black))
{
focusPen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot;
Rectangle focusBounds = e.Node.Bounds;
focusBounds.Size = new Size(focusBounds.Width - 1,
focusBounds.Height - 1);
e.Graphics.DrawRectangle(focusPen, focusBounds);
}
}

}追问

//演示为绿底白字
e.Graphics.FillRectangle(Brushes.DarkBlue, e.Node.Bounds);

这句话只并没有改变整行的默认颜色，我想改变整行的默认颜色，如何来写呢？
