You can easily expand/collapse TreeNodes when you click on their text. To achieve the task, you should subscribe to the BeforeClientClick event and use the client-side Toggle() method that expands/collapse the nodes. An example is shown below:
Example:
| ASPX |
 Copy Code |
|
...
<rad:radtreeview
runat="server"
ID="RadTreeView1"
BeforeClientClick="ToggleNode"
...
/>
<script language="javascript">
function ToggleNode(node)
{
node.Toggle();
}
</script>
...
|
