        dt.Columns.Add("SOT", typeof(Decimal));
        dt.Columns.Add("SVT", typeof(Decimal));
        dt.Columns.Add("SCT", typeof(Decimal));
        dt.Rows.Add(12.22, 23.44, 22.00);
        dt.Rows.Add(2.20, 23.00, 22.23);
        dt.Rows.Add(12.00, 23.20, 22.05);
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
    catch (Exception d)
    {
        Response.Write(d.Message.ToString());
    }
}

DataTable can take values like {12,10.5} instead of {12.00,10.50}. Is there any method to insert into DataTable with exactly two decimal places.

Solution 1

You know, 12 and 12.00 are the same Decimal value.
You shouldn't bother about number representation inside the database and do your formatting job on the GUI.

Solution 2

VB

Try like below:

dt.Rows.Add(12.22m, 23.44m, 22.00m);

or

Math.Round((Double)12.22, 2)

Thanks dude. It's Working.

I know this answers the question at hand, but it is much better to do the formatting in the presentation layer using String.Format().
Just like Solution 1 suggests.
