Batch edit data in grid across pages (server side paging) is only sending current page data

[Ed]

I am using MVC Complete v2013.2.918

I am working on supporting batch editing of a column (the percentage column - a decimal value) in the grid across pages when server side paging is used.  I am modeling my modifications based on this example:

When I click the save button (which calls grid.dataSource.sync()), it is currently only sending data for the current page (which is expected and why I'm trying to use something like the linked example above).  The issue now becomes: how can I modify the data sent from the client to the server to contain all the data across all pages instead of just the current page?  I now have the data (thanks to the example above), but don't know how to add it to the data sent to the server.

Thanks in advance

OK, I've got this working - saving the data as it changes in a variable and using that variable to populate an additional param on the AJAX POST that I use instead of the "models" param.  The only issue remaining is: if I'm on a page of data in the grid that doesn't have changes (and other pages do have changes - with those values stored in the global variable), dataSource.sync() doesn't call update.  How can I trick the grid into thinking there is data that needs to be updated in this case?

Thanks,

Hi Ed,

You could manually change the dirty flag of the dataItems you want to send, for example:  

grid.dataSource.data()[0].set("dirty", true)

Once you call the sync method every item with dirty flag will be sent to server.
