C# Wrong Loop On My DataGridView

Good day, I'm having an error. I choose the August 5, 2015 on the date picker with the loop count of 3. But I'm having a problem. I'm using add 15 prior to the given output. But the first count is wrong.

THE OUTPUT IN THE FIRST COUNT IS

8/20/2015
but it should be 
8/05/2015 because I use the 8/05/2015 on the datepicker.

I don't know what's the problem here.

Here's my code (This will be execute when the button "Calculate Schedule" is click"

private void execute_Click(object sender, EventArgs e)
{
   var fromDate = date_from.Value; // Getting the value from DatePicker

   int count;

   for (count = 0; count < 3; count++) {
      dgv_result.Rows.Add(1);
            int numrows = count + 1;

            fromDate = fromDate.AddDays(15); 

            dgv_result.Rows[count].Cells[1].Value = numrows; // Just for numbering the rows
            dgv_result.Rows[count].Cells[0].Value = fromDate.ToShortDateString();
   }
}

Here's my Screenshot

NOTE: Just check the Month only

You are adding days before you write your first row. So you need to .AddDays(15) at the end line of for loop.

You just have to put this line at the end of the loop:

for (count = 0; count < 3; count++) 
{
    dgv_result.Rows.Add(1);
    int numrows = count + 1;

    dgv_result.Rows[count].Cells[1].Value = numrows; // Just for numbering the rows
    dgv_result.Rows[count].Cells[0].Value = fromDate.ToShortDateString();

    //add days after adding the row, so next line will be effected by it
    fromDate = fromDate.AddDays(15); 
}

I am considering you're not using fromDate anywhere else and it is just for the loop.
