Inline Row Editing allows end users to inline edit multiple rows.
In this example we used ZK's databinding to deliver the ability to edit the entire row purely using ZK's MVVM based databinding.
Using databinding to deliver this functionality ensures a clean and easy to read code which delivers a powerful feature. The feature works by making use of two templates, one which outputs textboxes so the values can be edited and one which outputs labels which doesn't allow editing functionality.
