I am performing a text search in the cells of the GridView.  As I enumerate the cells, I set the row visibility to false.  However, the 'selectedrow' can never be set to false.  How do I make SelectedRows empty.  Nada.  And this is not a webcontrol, where you can set SelectedIndex to -1.

Are you using a foreach? If so, you cannot modify the collection referenced in the foreach. You could use a while loop:
while (this.dataGridView1.SelectedRows.Count > 0)
{
    foreach (DataGridViewCell cell in this.dataGridView1.SelectedRows[0].Cells)
    {
        // search cell
    }

    this.dataGridView1.SelectedRows[0].Selected = false;
}

Open in new window

>>  you cannot modify the collection referenced in the foreach

I should state this as, "you cannot remove/add elements to the collection referenced in the foreach within the foreach itself."

Use the Grid's ClearSelection() method

It is still not effective.  Try this:  if you enumerate all rows in a datagrid, setting them to Visible = False ... the first row (or whichever row has the carat beside it)  will still show.  How do we prevent this?
