推荐答案

以类似于以下内容的标记开始:

Start with mark-up similar to the following:

<asp:treeview xmlns:asp="#unknown">
    ID="tvRPM"
    runat="server"
    EnableClientScript="true"
    ExpandDepth="0"
    PopulateNodesFromClient="true"
    ShowLines="true"
    OnTreeNodePopulate="PopulateNode"/>
</asp:treeview>

然后，您将通过OnLoad事件填充父级，并从您附加到OnTreeNodePopulate事件的事件填充子级:在上述情况下，我调用了我的方法，而不是想象中的"PopulateNode".它具有以下签名:

You would then populate the parent from the OnLoad event and populate children from the event you attach to the OnTreeNodePopulate event: in the case above I have called my method, rather unimaginatively, ''PopulateNode''. It has this signature:

protected void PopulateNode(Object sender, TreeNodeEventArgs e)
{
	// Code to populate the child nodes...
}

这应该可以帮助您入门:您需要做一些进一步的研究，但这应该很有趣.

That should get you started: you''ll need to do some further research but that should be fun.
