1)  Enter the ListConverter name pairs for each list involved (e.g. Shipper and ShipperID) in the ListConverterNames.cs file in the Interface.Constants project/folder.

2)  Add the pair to the CreateServiceItemCore method of the ListConverterService (Foundation Module)

Market example:

 

3)  Create the MakeListConverter methods...one for each of the pair

Market example:

4) Bind the lists in the view's presenter

Market example:

EntityPropertyDescriptors.CustomerMasterPropertyDescriptor descriptors = EntityPropertyDescriptors.CustomerMaster;
SetBindingListConverter(descriptors.MarketMaster, ListConverterNames.MarketList);
SetBindingListConverter(descriptors.Market, ListConverterNames.MarketIDList);

 

 

 

 

 

The DevForce Object Mapper was used to create the business objects being referenced.  The ControlBindingManager is used to populate the view with loose controls based on the selected bound type.  I am following all DevForce protocols for creating a databound combobox...I have done this dozens of times in a non-CAB environments.  I drag the desired entitylist for autopopulation, then verify that the dataconverter is set to ListConverter, then (following the CAB example for TitleOfCourtesy) I set the DisplayMember to the appropriate property (valuemember is __Self).  The SetBindingListConverter (see above) *does* populate the combobox, but no item is selected when the main entity (Customer) is displayed on the view.  Even if I select a value from any combobox, then navigate away from the entity (or simply away from the combobox!), when I return no value is selected.

 

Somehow, I am not tying the ListConverter from the ListConverterService to the one created by the ControlBindingManager.

 

This seems contradictory--"EnablePreventFocusChange" will prevent shifting the focus away from the control while the value is invalid.  I.e., the cursor will be "stuck".  Which do you want?

 

It sounds like the list is working fine--the problem is that the bound value of the control isn't showing up.

 

Are you sure there is an entity to bind to and that its bound property has a legal value?

 

Was the binding created with the DevForce Object Mapper?

 

Is the bound property of the proper type?  Of the same type as the ValueMember specification of the ListConverter?

Several problems:

2)  EnableAllowFocusChange allows the user to move between controls (the "stuck" part is taken care of); however, the proper list item is still *not* selected.

3)  The Inherit and Disable options seem like they may violate other desireable features (validation, etc.).

 

So, I guess my original question about the binding still needs to be addressed.  How do I fill a list from a listconverter and select the proper item based on the object in view?  It just seems like the order of binding is swapped somehow.  Is there a different way to bind the lists earlier than the view?

 

Of course, I may not even be asking the right question, either.  I am still learning.  Thanks for being patient with me.

(AutoValidate is a property of System.Windows.Forms.UserControl)

 

Thanks,

I am following the Cabana example app.  The problem is that when the view is displayed, the list is filled properly; however, the screen is "stuck" in that combobox.  No value is selected for any combobox with an assigned ListConverter (total of three on this view).  I am forced to select an item from the list, then I can move to another field or even another page.

 

This is odd behavior.  I must be missing some little thing within the framework.

 

Thanks, in advance, for any help,

Bill
