Too Much Lost Time With ListView - HELP!

    Question

  • Background: 3 Tables: Table1, Table2, Table3. Table1 is the first in what amounts to a hierarchy. It has an Identity key. Table 2 is the second. It has an Identity key and also a field pointing to appropriate Key ID of table 1. Table 3 is the third table. It has an Identity key and also a field pointing to the appropriate Key ID of table 2. Using Entity Framework, Table 1 is loaded with a Dim t=from i in ef.T.Include(Table2). A stack panel with Textboxes displays data from Table1, good so far. A listview displays appropriate (i.e. data related to Table 1) data from Table 2, good so far. However, I cannot seem to define a binding that will load another Listview showing appropriate data from Table 3 based on a selection made from items displayed from Table 2 in the second listview. Any help resolving this would be much appreciated as I have spent mucho time searching and experimenting. Thanks.

  • Is the problem just defining the binding?  Have you tried something like this:

    "{Binding RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type YourTable2Type}}"

    Not sure if this is exactly what you mean but it sounds like it.  You might have to twiddle with the syntax if its what you are looking for.

  • Hi,

    You can bind the second ListView to the SelectedItem of the first ListView, there's a sample demonstrates how to do this on our All-In-One Code Framework project, you can check it here:

    If you have any questions, please feel free to let me know.
