Datagridview First Row Skip

[maheshwag]

software use: c#, VS-2005

I am trying to calculation on datagridview as below

private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)
{
   double dd = 1.768901;
   dd = Convert.ToDouble(dd.ToString("f2"));
   DataGridViewCellStyle fixedstyle = 
   new DataGridViewCellStyle();
   fixedstyle.Format = "f2";
   dataGridView1.Columns[1].DefaultCellStyle =fixedstyle;

   try
   {
    decimal sum = 0.00m;

    for (int i = 0; i < dataGridView1.Rows.Count - 1;i++)
    if (dataGridView1[1, i].Value != DBNull.Value)
    {
    sum=sum Convert.ToDecimal(dataGridView1[1,i].Value);
    label12.Text = sum.ToString("f2");
     }

   }

    catch (Exception ex)
    {
       MessageBox.Show(ex.Message);
    }
   }

The Problem is Total count from 2nd row not from begining rows.
e.g. :-

1st rows column value=12
2nd rows column value=12
3rd rows column value=12

The total shows 24 where actual totals is 36.

I think the datagridview skip first rows. How can i solve it?.

Note:- I set ColumnHeaderVis ible property set to false.

why u have i < dataGridView1.R ows.Count - 1.either make it i <= dataGridView1.R ows.Count - 1 or make it i < dataGridView1.R ows.Count

[maheshwag]

1. With i<= dataGridView1.R ows.Count-1 result is 0.00
e.g. if 1st row column value i enter 12.00 the total count result is 0.00

2. With i<dataGridView1 .Rows.Count Result is Error like Index was out of range. Index Must be non negative and less than size of collection parameter name:index

I wants to Share a knowledge with solution of above problem

The solution is:

    private void dataGridView1_CellValidated(object sender, DataGridViewCellEventArgs e)
        {
            decimal sum = 0.00m;

            for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {
                if (dataGridView1[1, i].Value != DBNull.Value)
                {
                    sum = sum + Convert.ToDecimal(dataGridView1[1, i].Value);
                    textBox1.Text = sum.ToString("f2");

                }

            }
        }

Just change the event to dataGridView_Ce llValidated.
