Javascript 在树视图中选择父节点时，如何选择所有子节点？（当从usercontrol使用treeview时）

javascript jquery asp.net .net vb.net

Javascript 在树视图中选择父节点时，如何选择所有子节点？（当从usercontrol使用treeview时）,javascript,jquery,asp.net,.net,vb.net,Javascript,Jquery,Asp.net,.net,Vb.net,我有一个usercontrol，它只有Treeview控件 <asp:TreeView ID="Tree_Index" Style="font-size: 11px; font-family: Tahoma; font-weight: bold; text-align: left;" runat="server" Width="10px" EnableClientScript="False" ShowCheckBoxes="All" ShowLines="True"> </

我有一个usercontrol，它只有Treeview控件

<asp:TreeView ID="Tree_Index" 
Style="font-size: 11px; font-family: Tahoma; font-weight: bold; text-align: left;" runat="server" Width="10px" 
EnableClientScript="False" ShowCheckBoxes="All" ShowLines="True">
</asp:TreeView>
假设我的aspx页面上有6个TreeView。选择父节点时，我希望选择父节点的所有子节点。树视图将有三个级别的节点。因此，应该为该特定树选择父节点内的所有节点

我如何实现这一点，因为ID是由我在aspx页面中设置的。如何使用javascript、jquery或用户控件的代码隐藏来实现这一点
