I tried to find but no solution.
Anyone plz help me.......

Thanks in advance.

There is no direct access to disable column sorting in the datagridview.
But you can try this:

For Each dgvCol As DataGridViewColumn In Me.DataGridView1.Columns
    dgvCol.SortMode = DataGridViewColumnSortMode.NotSortable
