        sql = "select * from color_mas"
        Dim dt As DataTable
        dt = DataTable(sql)
     
        If dt.Rows.Count > 0 Then

            'For j As Integer = 0 To dt.Rows.Count - 1

            Dim col As New DataGridViewComboBoxColumn
            col.DataPropertyName = "Color Name"
            col.HeaderText = "Colorname"
            col.Name = "Colorid"

            col.DataSource = dt
            col.DisplayMember = "Colorname"
            col.ValueMember = "Colorid"
            DataGridView1.Columns.Insert(0, col)
