fit dataGridView size to row's and columns's total size

Question

I want to make a dataGridView's size to fit the columns and rows total size. About total height, I managed to fit it to columns's height like that:

const int datagridLines = 30;
s.Height = dataGridView2.Columns[0].HeaderCell.Size.Height;
for (byte i = 0; i < datagridLines; i++)
{
  dataGridView2.Rows.Add();
  s.Height += dataGridView2.Rows[i].Height;
}
dataGridView2.ClientSize = s;

I tried some things to also fit the width but no luck. Any suggestions?

Thanks.

This should work:

int height = 0;
foreach (DataGridViewRow row in dataGridView1.Rows) {
    height += row.Height;
}
height += dataGridView1.ColumnHeadersHeight;

int width = 0;
foreach (DataGridViewColumn col in dataGridView1.Columns) {
    width += col.Width;
}
width += dataGridView1.RowHeadersWidth;

dataGridView1.ClientSize = new Size(width + 2, height + 2);

The + 2 to the width and height values are a fudge factor to account for the width of the DataGridView's interior elements. I recall seeing code somewhere that will allow you to get this value without the hard coded numbers but I can't find it now.
