QuestionTreeview in a thread [modified] Pin

Hi all, I am trying to populate a treeview from a webservice through a thread and get an invoke error when I call the function in the thread - outside the thread it works perfectly - but is too slow to be used outside a thread.

So wondered if there were anyone who have some experience on Invoking in treeviews?

my code is as follows:

private void ThreadingGroups()
{
    Thread TsGroups = new Thread(ThreadGroups);
    TsGroups.Start();
}

private void ThreadGroups()
{
    DataTable dt = DOCTemp.GetGroups();
    DataRow dr = dt.NewRow();
    dr[0] = "";
    dr[1] = "Default";
    dt.Rows.InsertAt(dr, 0);
    frmTemplateManager.treeView1.Nodes.Clear();
    for (int i = 0; i < dt.Rows.Count; i++)
    {
        TemplateManagerTreeView(dt.Rows[i]["id"].ToString(), dt.Rows[i]["name"].ToString());
    }
}

private void TemplateManagerTreeView(string id, string name)
{
    frmTemplateManager.treeView1.Nodes.Add(id.ToString(), name.ToString());
}

The function is basically updating a treeview located in form named frmTemplateManager and it iself it works quite well. Just need to find a way to get the Invoke to work in a way..

Cheers,
