Grid edit

In the software factory I have a grid edit button and this button does the following; make the entire grid editable.

In Universal having autoedit enabled gives the same result.

But clicking on edit above the grid only makes one row editable.

I tried to get the behaviour of the windows interface using a workflow but it did not work.

Should this work? And could give someone an example?

Expected behaviour;

Default the user is not able to edit.
After clicking a button  the user gets into the autoedit mode.
When done the user clicks “stop editing” and returns back to the default mode.

Thank you,

Daan
