[Solved] I am using 25 check boxes with 5 in a column and want to restrict to user select only one in a column ?

$("#btnSubmit").click(function(){

    var vCheckedCBCount =  $("input:checkbox").filter(function(index){ 
    return $(this)[0].checked == true;
    }).length;
    if(vCheckedCBCount > 1)
    {
        alert('You cannot check more than 1 check box.');
        return false;
    } 
});

        Dim i As Integer = 0
        While (i <> Me.DataGridView1.Rows.Count)
            Me.DataGridView1.Item(e.ColumnIndex, i).Value = False
            i = i + 1
        End While
    End Sub
