Thanks for reply Mike

now i little  modify my code:

protected override void OnLoad(EventArgs e)
  {
  base.OnLoad(e);
  // ->

  DataTable dt = new DataTable("dt");
  dt.Columns.Add("id", typeof(int));
  dt.Columns.Add("name", typeof(string));
  dt.Rows.Add(new object[] { 0, "sfd" });
  dt.Rows.Add(new object[] { 1, "abc" });

  ultraCombo1.DataSource = dt;
  ultraCombo1.ValueMember = "id";
  ultraCombo1.DisplayMember = "name";
  ultraCombo1.AutoCompleteMode = Infragistics.Win.AutoCompleteMode.None;
  ultraCombo1.RowSelected += new Infragistics.Win.UltraWinGrid.RowSelectedEventHandler(ultraCombo1_RowSelected);
  }

  void ultraCombo1_RowSelected(object sender, Infragistics.Win.UltraWinGrid.RowSelectedEventArgs e)
  {
  // Event is Fired!
  }

when i type "abc" RowSelected also fired.

Now is any way to avoid row auto select by typing value that equal to display member or value member? May be i should use reflection or override some protected method?

Hi worner,

I am facing the same situation my self. If you have a combo with a valuemember = 1 and a displaymember = "Money", when you type "1" into the combo Money is selected and this is not the way i want it to work. I only want the combo to select the Displaymembers when i type in the combo.

What i did to get around this was to set the displaymember as the valuemember .i.e., it has both roles. So now when i type "1" in the combo "Money" does NOT come up.

What is means how eva is that if u want the ID of the selected row you can't just say Combo.value, you have to  say Combo.SelectedRow.Cell[0].value.

it's a work around,  but it seems to work. Hopefully the infragistics team will be able to give us a better solution

There's no way to stop the event from firing in just that case.

How to prevent row selecting when you type text like ValueMember or DisplayMember?

Please help
