    Remove item gridView1 and gridView2 error Deleted row information cannot be access ?

    Remove item gridView1 and gridView2 error Deleted row information cannot be accessed through the row ?

    I use nested while command, to run two gridView1 and gridView1 if gridView1 record is equal to gridView1 record, delete them, but when running, I get an error: "Deleted row information cannot be accessed through the row"

    Code:
    private void cmdSSLoaiTru_Click(object sender, EventArgs e)
            {
                
                 while (x2 < gridView2.DataRowCount) //Gv.DataRowCount //Gv.RowCount
                 {
                     gridView2.SelectRow(x2);
                     DataRow row2 = gridView2.GetDataRow(gridView2.GetVisibleRowHandle(x2));
                     while (x1 < gridView1.DataRowCount && bStop == true) //Gv.DataRowCount //Gv.RowCount
                     {
                         gridView1.SelectRow(x1);
                         DataRow row1 = gridView1.GetDataRow(x1);//.GetDataRow(gridView1.GetVisibleRowHandle(x1));                      
                         if ((row2["HD"].ToString() == row1["HD"].ToString()) && (row2["SLUONG"].ToString() == row1["SLUONG"].ToString()) && (row2["DONGIA"].ToString() == row1["DONGIA"].ToString())) //error here
                         {
                             gridView1.DeleteRow(x1);
                             gridView2.DeleteRow(x2);
                         }
                         x1++;
                     }
                     x2++;
                     x1 = 0;
                 }
