Datatable row deletion in Gridview

Hi,
 I have a gridview, which is binded to datatable. I too have a checkbox in each row in gridview. Now, i would like to delete the selected rows by selecting the checkbox in button click event. I have tried as follows.
           foreach (GridViewRow row in GridView1.Rows)
            {                
                bool ischecked = ((CheckBox)row.FindControl("chkDelete")).Checked;
                if (ischecked == true)
                {                    
                    row.Cells.Clear();
                }
            }    

 It worked fine.But, when i add a new row to gridview i see that the deleted rows are getting displayed back again. so, can anybody help me out to delete a row in datatable in gridview?

add a bit column to ur data table

then that check box will automatically come

if not u can manually add that

then on row change event of the datatable u can do this
FTable.RowChanged += new DataRowChangeEventHandler(FTable_RowChanged);


private void FTable_RowChanged(object sender, DataRowChangeEventArgs e)
            {
                  if(Convert.ToBoolean(e.Row["CHK"]))
                  {
                        e.Row.Delete();
                  }
            }

Am I wrong in thinking that there is no code in there to actually delete the row from the database, so when the control is re-bound the data will still appear?
