Can I set Node CheckState on Client Side

[Ryan]

Is it possible to set TreeNode CheckState in the client side. If yes how?

It seems that only retrieving the value is documented. I have also set the class of the created span elements to change display but when it goes back to the server, the check state remains at unchecked.

Hello Ryan,

Once you have a client-side reference to a Node, you can call function set_checked() to check/uncheck the node.

[ASPX]

telerik:radtreeview id="RadTreeView1" runat="server" CheckBoxes="true"
<Nodes>
<telerik:RadTreeNode runat="server" Text="Root RadTreeNode1">
</telerik:RadTreeNode>
   . . .
</Nodes>
</telerik:radtreeview>

[JavaScript]

<script type="text/javascript">
function checkNode()
{
    var tree = $find("<%= RadTreeView1.ClientID %>");
    var checkNode = tree.findNodeByText("Root RadTreeNode1");
    checkNode.set_checked(true);
}
</script>

Thanks,
Princy.
