Is it possible to select leaf tree node programatically in asp.net

Question

I am working on TreeView with checkbox(Parent and leaf) where I have to make some leaf nodes selected programatically.

Is it possible ?

I tried forach loop on treeview node but can make selected(checkbox) particular node.

I tried following solution Is it possible to get one of the child node get selected programatically

but I am getting error on SelectedNode that its read only

Code is as below :

<asp:TreeView ID="TreeView1" runat="server" ShowCheckBoxes="Leaf">
</asp:TreeView>

Now I am adding treeview node

for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
    {
    TreeView1.Nodes.Add(new TreeNode(ds.Tables[0].Rows[i]["ModuleName"].ToString(), ds.Tables[0].Rows[i]["Id"].ToString()));

   DataRow[] result = ds.Tables[1].Select("ModuleId = '"+ds.Tables[0].Rows[i]["Id"].ToString()+"'");
                    foreach (DataRow row in result)
                    {
                        TreeView1.Nodes[i].ChildNodes.Add(new TreeNode(row["PageCode"].ToString(), row["Id"].ToString()));
                    }
                }

and Now how do make particular leaf node selected ??

Please add you code so we can understand and answer proper.

If no TreeNode is currently selected, the SelectedNode property is null.
