Simple trick: replace day for each date with 1 and now you can validate
In a DataGridView DataBindingComplete[^] event:

C#

foreach (DataGridViewRow i in dataGridView1.Rows)
{
    String s = i.Cells[Index].ToString;
    DateTime d = DateTime.Parse(s);
    d.Day = 1
    i.Cells[Index].Value = d.ToString();
}

I don't have C# compilator, so excuse me if i made an error in above code.

As seen from the question it seems that the requirement is to validate the entry in the TextBoxColumn of DataGridView such that only month and year is entered. For this purpose I think the the CellValidating event of DataGridView can be used as follows:

C#

dataGridView1.CellValidating += (s, args) => {
    //If the column index is not the index of the desired column then return
    if (args.ColumnIndex != 2)
        return;
    if (!Regex.IsMatch((string)args.FormattedValue,@"\d{2}/\d{4}", RegexOptions.CultureInvariant)){
        MessageBox.Show("Please enter month and year as 05/2012");
        args.Cancel=true;
    }

};

In the above example the MM/yyyy format is used. You can check any other format including the valid ranges with appropriate regular expression pattern.
