How to fix length of characters in DataGrid cells

I have a datagrid with a column, ID with values like 1,2,3,4,5....10,11,12,13... I want all the values should be of length two, means i want the values as 01,02,03....10,11,12... How to do it?

EDIT I am using Winforms.

EDIT

    if (dg.Columns[e.ColumnIndex].Name == "Id")
    {
        try
        {
            //e.Value = String.Format("{0:00.0}", e.Value);

            DataGridViewCellStyle ca = new DataGridViewCellStyle();
            ca.ForeColor = System.Drawing.Color.Red;
            ca.Format = "d2";

            dg.Columns[e.Co开发者_开发技巧lumnIndex].DefaultCellStyle = ca;
            e.FormattingApplied = true;
        }
        catch (FormatException)
        {
            e.FormattingApplied = false;
        }
    }

Here iam able to change backcolor and forecolor but the text format remains the same, no matter what i do. I even tried using String.Format (commented line) but its not working either. I tried your code also, its not working. don't know whats wrong.

(DataGridView)

For a DataGridView, try setting the Format property of the DefaultCellStyle like this:

this.dataGridView1.Columns["COLUMN_NAME"].DefaultCellStyle.Format = "d2";

(WinForms DataGrid answer)

In WinForms, MSDN says there's a Format property on the DataGridTextBoxColumn; I don't use WinForms often enough to verify that that's the correct type of column.

(Web Forms answer)

You can use the DataFormatString property on the column:

DataFormatString="{0:D2}"

Formatting the string with ToString("00") worked fine.
