BrowseDialog - How to show in list the value of other table

Sure you can. In the main StatesBO create a Custom Property CountryName, this property will have code to get the country name based on the StateBO.CountryFK, then in the Dialog Browser add the CountryName property to be shown in the ListView. Of course, first re-build the BO library project or the solution so the new property will show up in the designers.

Protected Overrides Function GetCustomBindablePropertyDescriptors() As FieldPropertyDescriptor()
     ' Create and return a new array of FieldPropertyDescriptor objects that contains 
     ' the ReflectionPropertyDescriptor for the Custom Fields.
     Return New FieldPropertyDescriptor() _
          {New ReflectionPropertyDescriptor("CountryName", GetType(StatesBO))}
End Function

     Get
          If String.IsNullOrEmpty(Me.FK_Country) Then
               Return String.Empty
          End If
          Dim loLookupBO As New CountryBO
          loLookupBO.FillByPrimaryKey(Me.FK_Country)
          If loLookupBO.Count = 1 Then
               Return loLookupBO.CountryName
          Else
               Return String.Empty
          End If
     End Get
End Property

There are a lot information about Custom Field Properties in the help file and in these forums, so please check it out for better technical understanding. This is just another feature I fall in love to Tongue
