How can we just clear radgridview

Hi All,

How can we just clear radgridview, clear row, column, relation also on their template ?. Then radgridview being like the first time it loaded when then application run. So we can define columns on it over and over. Instead of using those :

        RadGridView1.DataSource = Nothing
        template.DataSource = Nothing
        template1.DataSource = Nothing

        While Me.RadGridView1.Rows.Count > 0
        Me.RadGridView1.Rows.RemoveAt(Me.RadGridView1.Rows.Count - 1)
        End While

        While Me.RadGridView1.Columns.Count > 0
            RadGridView1.Columns.RemoveAt(Me.RadGridView1.Columns.Count - 1)
        End While

        While template.Rows.Count > 0
        template.Rows.RemoveAt(template.Rows.Count - 1)
        End While

        While Me.RadGridView1.Relations.Count > 0
            Me.RadGridView1.Relations.RemoveAt(Me.RadGridView1.Relations.Count - 1)
        End While

Thanks in advance
