Combo box works differently with UDO

Question

Hi guys,
I have created a combo box on a UDO. I am trying to catch the event of when a value is selected in the combo box, but it is not working as it should. I have used the same code on a simple form and it works. It doesn't work on the UDO however. Here is my code:
I declare the combo box:
            oItem = oForm.Items.Add("CntDetails", SAPbouiCOM.BoFormItemTypes.it_COMBO_BOX);
            oItem.Left = 300;
            oItem.Width = 60;
            oItem.Top = 290;
            oItem.Height = 14;
            oItem.AffectsFormMode = true;
            oItem.FromPane = 1;
            oItem.ToPane = 1;
            oCombo = ((SAPbouiCOM.ComboBox)(oItem.Specific));
            oCombo.DataBind.SetBound(true, "@CENTRIX_OJEA", "U_CENTRIX_CntDetails");
            oCombo.ValidValues.Add("All", "All");
            oCombo.ValidValues.Add("None", "None");
            oCombo.ValidValues.Add("More", "More");
            oCombo.Select(0, SAPbouiCOM.BoSearchKey.psk_Index);
The in the ItemEvent part I use this code:
        if (pVal.ItemUID == "CntDetails" && pVal.EventType.Equals(SAPbouiCOM.BoEventTypes.et_COMBO_SELECT) && pVal.Before_Action == false)
            try
                Globals.SBO_Application.MessageBox("test", 1, "OK", "Cancel", "");
            catch
                Globals.SBO_Application.MessageBox("Error", 1, "OK", "Cancel", "");
Am I doing something wrong?
Thanks

Hi Costas,
Put a breakpoint in this line of code
if (pVal.ItemUID == "CntDetails" && pVal.EventType.Equals(SAPbouiCOM.BoEventTypes.et_COMBO_SELECT) && pVal.Before_Action == false)
See if it is reached.
