I have a grid whose datasource has a filter set on a foreign key. It's a remote datasource to a SharePoint 2010 list odata service. The create command in the grid's toolbar does not do anything. As soon as I remove the filter from the datasource, the create command works again. How can I get the create command to work with the filter set? I assume I need to find a way to set the foreign key on the newly created object to the same value as the filter and only then will the new object show up in the grid.
