Creating a DataGrid with Inline Editing
Using the techniques for dynamically creating controls and utilizing the AJAX
features in QCubed, we update our Person datagrid to include functionality for
We must first add a $intEditPersonId in the FormBase to keep track of which
Person (if any) we are currently editing. We then must define the First
and Last Name TextBoxes, as well as Save and Cancel Buttons.
Note that we only need to define one of each, because only one Person can be edited
at a time. The textboxes have EscapeKeyEvents defined on them to
perform a "Cancel", and the "Save" button is set to be a PrimaryButton. This
allows the textboxes to be sensitive to the Enter and Escape keys for
saving and cancelling, respectively.
We also define render methods for each of the columns
to properly display either the name or the TextBox, depending on the row we are
rendering and which Person we are editing.
And finally, we add a btnNew at the bottom to allow the user to create new
Person objects. If they want to create a new person, the $intEditPersonId
is set to -1, and we get the datagrid to basically act as if it's editing a blank person.
