   I was reading the following but not sure that will work for me. What I want to do is manipulate the LookupDialogQueryString and LookupQueryString based on values in other controls in the viewer as well as a field from the viewers SmartDateSource:LinkDataSource

   Where is the best place do do this? I was trying in BeforePerformLookup as well as ShowLookupDialog.

   Maybe I just do not understand the syntax.
   
   I cant use the the ForeignFields of the lookup control as the values I want to use to manipulate the query are not defined as foreign fields in the viewers adapters.
   
   The SmartBusinessEntityLookup now provides support for Foreign Fields when performing the lookup on leave or after the timer interval and when opening the Lookup Dialog.
   
   >> This is exactly what I need but not based on ForeignFields. If ForeignFields are not specified then the logic does not appear to execute.
   
   Are you saying I can use this when they are not ForeignFields?

   The lookup or combo-boxes Foreign fields have nothing to do this the SmartBusinessEntityAdapter'sforeign fields.
   
   Similar concept - yes. But different use case here. 
   
   Rather than telling what you believe you can't do, can you please tell, what you want to do?

   I thought I did...
   
   I have disabled the lookup timer.
   
   I have defined in the lookup designed the following Lookup Query String as FOR EACH eItem WHERE eItem.ItemNum = "&1"
   
   This works....
   
   Now, I would like to include other values in that Lookup Query String. In one use case it would be from a value of a control in the viewer. In another use case it would be a value from the Viewer's adapters SmartDataSource:LinkDataSource
   
   I am asking what is the best way to do that?
   
   What I have tried is I defined the ProvideForeignFieldValue event for the lookup. This does not appear to get called unless I defined a value in the lookup ForeignFields property.
   
   If I add something to the ForeignFields property it will throw an error unless it is defined the same as the ForeignFields of the adapter or at least that is what it appears.

   The lookups and smartcombo's foreign fields method does not support to access field values from the viewers's smartdatasource's smartdatasource. If that's what you want to do.
   
   In that case, you need to subscribe to the ProvideForeignFieldValue event of the control and provide those values through your own code.
   
   "What I have tried is I defined the ProvideForeignFieldValue event for the lookup. This does not appear to get called unless I defined a value in the lookup ForeignFields property."
   
   That is expected.
   
   "If I add something to the ForeignFields property it will throw an error unless it is defined the same as the ForeignFields of the adapter or at least that is what it appears."
   
   Which error?
   
   That sounds like you are making a mistake somewhere and I'd like to see more details to help.

   Okay,
   
   I have subscribed to the ProvideForeignFieldValue . 
   
   I have added @PackNum@ as a ForeignField and I get the following as soon as I open the form
   
   Unable to subscribe CurrentChanged event for Foreign Field @PackNum@ or eBatchItem_ItemNum. The Viewer's SmartDataSource is not valid.

   Where/how are you setting the viewer's SmartDataSource property? Or LinkDataSource property? 
   
   That does not seem to be see early enough.

   The LinkDataSource is set in the designer.
   
   This viewer is on page 2 of an ultratabcontrol.

    Hey Mike,
    
    Any further thoughts on what I might be doing wrong?

    I'm afraid there's not a log you can do.
    
    What you should do is to create a support ticket and attach the Form's source code. There's not a lot we can do (and you can do) to influence the order in which EndInit is called on that viewer. Even though we have tested a bunch of possible layouts, something may be special in your form.
    
    So we might have to move the initialization of the events from the EndInit (where usually the links are set) to later in the OnLoad method. 
    
    But that will require a bit of testing again on our end.

    Okay, I will do that. For now I wrote around it by not defining a LookupQueryString in the designed and assigning it in BeforePerfomLookup. That seems to do the trick for now.
    
    Thanks.
