推荐答案

向TreeView 控件添加TreeNodeCheckChanged Event Handler，在PostBack 上，您将获得选定的节点值和完整路径，如下所示:

Add a TreeNodeCheckChanged Event Handler to TreeView control and on PostBack you will get the selected node value and full path as follows:

protected void TreeView1_TreeNodeCheckChanged(object sender, TreeNodeEventArgs e)
{
        string nodePath = e.Node.ValuePath;
        string nodeValue = e.Node.Value;
}

基于nodeValue 选择(或nodePath 选择)，您从数据库中检索数据并填充在GridView中.

您可以在此处看到许多TreeView的示例: http://quickstarts.asp.net /QuickStartv20/aspnet/doc/ctrlref/navigation/treeview.aspx [ ^ ]

Based on the nodeValue selection (Or, nodePath selection) you retrieve data from the database and populate in the GridView.

You can see a number of examples of TreeView here : http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/navigation/treeview.aspx[^]
