Hi
I need some assistance with something I'm working on. I have a kendo grid that's populated by a datasource that queries a view in a sql database. (I use a view as it contains a join between 2 tables, getting the latest status of the parent record that was added in a child table). The grid has a custom command column that launches a window that uses a template. That template contains a form that binds to another datasource that's filtered by the id of the selected row in it's parent grid. That form binds ok and the values appear as they should, but the datasource will not sync. I get a 400 bad request error when I click the save button. Could somebody please look at the code below and see if they can figure out why it won't sync. Any help would be greatly appreciated.
Regards

I reviewed the provided code snippets, but I am still not sure what exactly is causing this. Would you mind sharing the request details and its response? You can do that either by examining the browser's network tab or record a session with Fiddler.

Hi Alexander
Thanks for your reply. I managed to get it to work yesterday. I took out the "batch: true" option in the 2nd datasource and the request works.
Oddly enough, the code that works puts double quotes around the number fields in the request to update when the batch option is taken out (maybe there's a reason for that?). Here is part of the request that creates the error:
Incident: "Bugs in rice! They were found when cooking."
IncidentDate: "2015-03-03T17:41:17.000Z"
IncidentID: 2517
IncidentOriginID: 5
IncidentsTypeID: 1
LoggedDate: "2015-03-04T17:41:17.000Z"
Logger: "Webster, Steven"
And here is the request that works. Note the quotation marks around the number fields:
Incident: "Bugs in rice! They were found when cooking."
IncidentDate: "2015-03-04T17:41:17.000Z"
IncidentID: "2517"
IncidentOriginID: "5"
IncidentsTypeID: "1"
LoggedDate: "2015-03-04T17:41:17.000Z"
Logger: "Webster, Steven"
The quotes might get added in case the field's type is not explicitly specified in the DataSource's schema.model option. If that is indeed the case, then the DataSource will treat those fields as strings, hence the quotes.

Hi there
They are specified! It's simply removing the "batch" option from the datasource that adds the quotes. But the funny thing is, by adding the quotes, the requests writes to the database!
I apologize for misleading you. In this case strings are added, because the DataSource type is OData and this is what the server would expect. Since the OData DataSource does not support batch operations out of the box, the code that adds the quotes is not executed when enabling the batch option. You can find more details and examples on that topic here.
