Disable Checkbox Server Side on Node

[Mike]

My scenario is this, I have a parent check box and when it gets checked, I want to set its child checkboxes to checked and disable the checkboxes. I have seen many posts on how to do this client side, but none on server side. How can I do this server side? Thanks.

Hi Mike,

Give a try with following code in order to disable child nodes on checking a node.

C#:

protected void RadTreeView1_NodeCheck(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
    if (e.Node.Checked)
    {
        for (int i = 0; i < e.Node.Nodes.Count; i++)
        {
            e.Node.Nodes[i].Enabled = false;
        }
    }
    else
    {
        for (int i = 0; i < e.Node.Nodes.Count; i++)
        {
            e.Node.Nodes[i].Enabled = true;
            e.Node.Nodes[i].Checked = false;
        }
    }
}
