datagrid twoway programmatically

Question

I have a DataGrid that displays one of several tables:

C#

var db = new XXXXDataContext();
if(....)
 dg.ItemsSource = db.tableA;
else
 dg.ItemsSource = db.tableB;

This works, but the DataGrid is not updated with changes in the database. How do I set
the binding mode to TwoWay in code behind?

And what, if you use just one way, DataGrid updates changes in database automatically? Tell me about it!

Make sure you Bind again after making changes (CRUD operations. (Create, Delete, Update)).

I think you should have posted this as an answer, since I'd guess it's probably is the reason the OP is not observing two-way binding. Then I could vote for your answer :)

All of your data grid columns should be TwoWay mode enabled as:

C#

<datagridtextcolumn width="Auto" header="TableAID" binding="{Binding TableACode, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}" />
