What is the best way to submit Empty values in the Two Grid Sample?

[YarikK78]

Hi

I'm trying to use approach from Two Grid Sample,
I move record from one grid to the second, click Submit, Submit was successfull.

Now I move record back, so second grid is empty, also I need to let server know about this event, but clicking on Submit do nothing.

It can be reproduced on Two Grid sample itself.

Should I check record count in the grid and if 0, then insert fake empty record and submitData, on the server side I will check fake record and clear appropriate table? Don't like this approach, maybe there is exists a better way?

Thanks

Hi,

If there is no data in grid, the .submitData() does nothing.

You could check grid.store.getCount(). If it's 0, you could use DirectMethod to pass this info on a server.

I thought this record will be moved to the deleted collection, and send to the server

so on server side I can extract it something like this

var data = dataHandler.ObjectData<...>();
foreach (var item in data.Deleted)
{
}

Repeat myself, .submitData() passes the grid's data to a server.

To pass modified, deleted, new records, you could use grid.save() method. But it doesn't pass records which was not changed.
