How to delete selected nodes in TreeView

name001

protected void btnDelSub_Click (object sender, EventArgs e)
    {
        string strParentID = this.tvwType.SelectedNode.Value.ToString (). Trim ();
        string strParent = this.tvwType.SelectedNode.Value.ToString (). Trim () + ",";
        this.tvwType.SelectedNode.ChildNodes.Clear ();
    }

In this way, only the nodes below the selected node can be deleted, but the node itself cannot be deleted.

Big brother upstairs,

 System.Web.UI.WebControls.TreeNode does not contain the definition of RemoveAt,

Do you want to add USING?

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

Haha, it still doesn't work
This line tvwType.SelectedNode.Parent.ChildNodes.Remove (this.tvwType.SelectedNode);

Thank you anyway
