Hello,

One way to do it is to use the CellValidating event.

See here: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellvalidating.aspx[^]

you could do it like that:

C#

private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
    if (e.ColumnIndex == _indexOfColumnTocheck)
    {
        int value;
        if (int.TryParse((string)e.FormattedValue, out value))
        {
            if (value > 100) { e.Cancel = true; }
        }
        else
        {
            e.Cancel = true;
        }
    }
}

Valery.
