Question

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.ColumnIndex].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.

Answer 1

Formatting the string with ToString(“00”) worked fine.
