Setting Indeterminate check state - this time - on server side

[Aykut]

Hi,
Is it possible to set a node's checked state to indeterminate even if it doesn't have child nodes?
And I want to do it on server side this time.
I tried to use your previous reply but it couldnt find the node :

ScriptManager.RegisterStartupScript(Page, typeof(Page), "aa", RadTreeView1.Nodes[i].ClientID+".get_checkBoxElement().className = 'rtIndeterminate';", true);

Regards.

Aykut,

I tried different approach for achieving this functionality. I have added an HiddenField control and passed the value to client side in order to apply the desired class for RadTreeNode in client side. Here is the code which I tried.

ASPX:

<telerik:radtreeview id="RadTreeView1" runat="server" CheckBoxes="true">
<Nodes>
 . . .
</Nodes>
</telerik:radtreeview>
<asp:HiddenField ID="HiddenField1" runat="server" />

CS:

protected void Button3_Click(object sender, EventArgs e)
{
    int i = 0;
    HiddenField1.Value = i.ToString();
    string script = "<script language='javascript' type='text/javascript'>Sys.Application.add_load(test);</script>";
    ClientScript.RegisterStartupScript(this.GetType(), "test", script); // Call the client function to apply CSS
}

JavaScript:

<script type="text/javascript">
function test()
{
    var value = document.getElementById('HiddenField1').value; //Get value passed from server
    var tree = $find("<%= RadTreeView1.ClientID %>");
    var node = tree.get_nodes().getNode(value);
    node.get_checkBoxElement().className = "rtIndeterminate";
}
</script>

Thanks,
Shinu.
