Waoula, Check the connection type your report uses internally when you designed it. Crystal likes to flake out when using certain connections. Try using the OLE DB (ADO) connection as a datasource when designing the report. Easiest way to change the datasource internally is by using the Set Datasource Location function, otherwise you will have to recreate some of the report. Let me know if that helps at all.

Thanks Guys. in fact i found it, all i have to do is: declaring a new event to my user control Public Event Selected_Index_Changed() and this Public Sub My_ComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles My_ComboBox.SelectedIndexChanged Index = Me.My_ComboBox.SelectedIndex RaiseEvent Selected_Index_Changed() End Sub so when the combo box change index the user control raiseevent Selected_Index_Changed this way i can use it in the original form sorry if my post was to long just wanted to share my ideas and make the code much more better thanks again. waelhawari
