title: TableAdapter.Update don't update
body: <p>I tried to add data from data set to access database with TableAdapter.Update() method, but it doesn't function. Here is my code. I have DataGridView on my Windows Form, Table (Users) are binding to DataGridView.</p>
  
  <pre><code>private void btnScanGroups_Click(object sender, EventArgs e)
  {      
      foreach (UserGroup group in g)
      {
          string groupName = group.Name;              
          string groupID = group.Link;
          int userID = 1;
          groupsTableAdapter.InsertGroupsQuery(groupName, groupID, userID);
  
          text = text+"\n added "+groupName + " - " + groupID;
  
          richTxtBoxStatus.Text = text;   
      }
  
      groupsTableAdapter.Fill(facebookGroupAutoPostDBDataSet.Groups);
      groupsBindingSource.EndEdit();
      groupsTableAdapter.Update(facebookGroupAutoPostDBDataSet.Groups);
  } 
  </code></pre>
