Hello Shiva,

I hope the following logic will help you in hiding the leaf nodes in self referencing hierarchy.

CS:

ArrayList list = new ArrayList();
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

    CreateExpandCollapseButton(e.Item, "EmployeeID");

 

    if (e.Item is GridDataItem)

    {

        string value = ((GridDataItem)e.Item)["ReportsTo"].Text;

        if (!list.Contains(value))

        {

            list.Add(value);

        }

    }

}

 

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

    foreach ( GridDataItem item in RadGrid1.Items )

    {

        if (!list.Contains(item["EmployeeID"].Text))

        {

            item.Visible = false;

        }

    }

}

The above example is based on the demo : Self-referencing Hierarchy
