Custom client-side logic implementation in the grid with multi-row editing

Custom logic implemented in this example allows the end-user to select a limited number of named columns via comboboxes. The maximum number of columns the user can select is defined by a numeric column value, which he can also change. The only callback is used to post the entire grid page data.
To work in multi-row-edit mode, scripts and ClientInstanceName property values are generated programmatically.
