i try to automatic execute rows in datagridview the use thread.sleep. while i execute button StartAuthorization, i want execute the data Rows one by one and remove rows if rows after executed; i tried this code :

private void button7_Click_1(object sender, EventArgs e)
{
 Thread.Sleep(10000);
 while (dataGridView1.Rows.Count > 0)
 {
  RunAtomationRun(); // method to execute rows in datagridview
  int selectedrowindex = dataGridView1.SelectedCells[0].RowIndex;
  DataGridViewRow selectedRow = dataGridView1.Rows[selectedrowindex];
  DataGridView1.Rows.RemoveAt(this.dataGridView1.SelectedCells[0].RowIndex);
 }
}

but not works ? any idea?

Answer 1

You should check if there are actually rows selected before using selectedrowindex . But how does your function select the row to work on?

You should really pass the row to the function and remove it when the function succeeds:

private void button7_Click_1(object sender, EventArgs e)
{
 Thread.Sleep(10000);
 while (dataGridView1.Rows.Count > 0)
 {
  DataGridViewRow currentRow = dataGridView1.Rows[0];
  RunAtomationRun(currentRow); // method to execute rows in datagridview
  DataGridView1.Rows.Remove(currentRow);
 }
}

Or let the function remove the row on success, I suppose it already knows wich one it is working on:

private void RunAtomationRun()
{
 // Find row to work on
 DataGridViewRow currentRow = ...

 // Work on row...

 // Delete Row on success
 DataGridView1.Rows.Remove(currentRow);
}

Both variants should fix your problem.
