GridView's RowDataBound equivalent event in Windows DataGridView

The DataGridView doesn't have the same event handling as in ASP.NET.

What you could do is handle RowsAdded event, but note that more than one row can be added when this event fires. An example:

C#

private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
    for (int i = e.RowIndex; i < e.RowCount + e.RowIndex; i++)
    {
        Console.WriteLine("Row " + i.ToString() + " added");
    }
}

Also, this event is a bit 'buggy' - at the moment when it's databound it may fire more than once for each row, but afterwards it behaves correctly - when you add a new row to data source, it's fired only once.

But, I should probably mention (even if that's not your original question), that if you used this event in ASPX to handle output formatting, than here an equivalent would actually be CellFormatting event - this event is called whenever the cells needs to display it's value.

2. RowDataBound for DatagridView Windows Forms[^]

I found that if the cell was not visible, ie off the right-hand edge of the screen, the row was not painted.

I've instead linked the code to RowPrePaint event.

private void dataGridView1_RowPrePaint ( object sender, DataGridViewRowPrePaintEventArgs e )
{
  if ( (bool)dataGridView1.Rows[e.RowIndex].Cells[userColumn].Value == true )
  {
    dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.MistyRose;
  }
}
