TreeView的SelectedIndexChange事件怎么一点反应也没有啊？

[大可山人]

这个连 Response.Write("OOOOO");这个语句也没有输出？

<Script language="C#" runat="server">
......
private void TreeView1_SelectedIndexChange(Object sender,TreeViewSelectEventArgs e)
{
SelectedTypeIDs.Value = TreeView1.GetNodeFromIndex(e.NewNode).Text;
Response.Write("OOOOO");
}
....
</script>

<form runat="server">
<IE:TreeView id="TreeView1" runat="server" EXPANDLEVEL=2 OnSelectedIndexChange="TreeView1_SelectedIndexChange"
AutoPostBack="true" onexpand="TreeView1_Expand" oncheck="TreeView1_onCheck" />
<input type="text" id="SelectedTypeIDs" name="SelectedTypeIDs" runat="server">
</form>

autopostback = true

页面上有验证控件吗？

[大可山人]

AutoPostBack已设为true，见上面代码。

页面上也没有验证控件。但有onexpand及oncheck事件，谢谢 acewang()提醒，已经搞好！原来是由于Page_Load中有一个：
TreeView1.Attributes.Add("onselectedindexchange","return TreeView1_AfterCheck()");
隐掉后就正常了。
