I have run into a small problem here...
I have a usercontrol with a datagrid - this datagrid has a datasource, lets call it SourceOne.
Now, within this grid I have a custom cell template and in this I have a combobox that needs data from a different source, SourceTwo. BUT it only uses SourceOne which is assigned to the parent grid. The combobox must bind to true/false values converted to textual values using an IValueConverter. Is what im trying to do possible?
