winform 中 怎样点击treeview节点 对应节点变色?

[itliyi]

如题

[jwdream2008]

 
 private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
        {
            e.Node.ForeColor = Color.Red;
        }

[itliyi]

但是要点击下一个节点效果才会出来？怎么解决?

[h_w_king]

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
e.Node.ForeColor = Color.Red;
this.Refresh();
}

[h_w_king]

写错了，是
　this.treeView1.Refresh();

[itliyi]

还是不行啊 ，是不是也要改下背景？

[h_w_king]

一般情况下，点击treeview节点，　节点呈选中状态．是蓝底白字．
你可以设置该treeview的节点不被选中．

[levinstong]

namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
e.Node.ForeColor = Color.Red;
this.treeView1.Refresh();
}
}
}

怎样设置节点不被选中？

單擊事件~~
點擊出現變色~！
private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
e.Node.ForeColor = Color.Red;
}
或是其他的顏色 你自己設置

[itliyi]

不行 点击下一个节点后才出现变色

[zgke]

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
TreeView _TreeView =(TreeView)sender;
Control _SetLabel =_TreeView.Controls["SelectLab"];
if(_SetLabel==null)
{
Label _Label =new Label();
_Label.Name = "SelectLab";
_Label.AutoSize=false;
_Label.BackColor=Color.Yellow;
_Label.ForeColor=Color.Red;
_Label.Font = _TreeView.Font;
_TreeView.Controls.Add(_Label);
_SetLabel=_Label;
}
_SetLabel.Size=new Size(e.Node.Bounds.Width+5,e.Node.Bounds.Height);
_SetLabel.Location = new Point(e.Node.Bounds.X, e.Node.Bounds.Y);
_SetLabel.Text = e.Node.Text;
}
不知道你要的是不是这个效果

[itliyi]
