Destroy(remote) - sending IDs

[Curt Rabon]

In the following documentation page: docs.telerik.com/kendo-ui/framework/datasource/crud

you state: "The destroy action submits the data item(s) that should be deleted, or just its ID(s)."

Please explain how we can choose to send just the ID(s) and not the data-items (models).  If it's a config setting, then please tell me where it should be set.  If it has to be done manually by me, please give an example.

Hello Curt Rabon,

The parameterMap function is responsible for sending data to the server-side. So you can modify the paremeterMap option and send only the information that you need. Here is the relevant documentation article:

Yes, I'm very familiar with the parameterMap feature, and I already know how to use that to send just the IDs when the "operation" argument to that function == "destroy".

 However, I'm using the MVC wrappers, and FOR THE GRID, it looks like you do some special things in this parameterMap function for the "read" operation, when server-side filtering is used.  For example, when the grid is using server-operations and a filter is applied to a column, it seems you put the filtering parameters in a special format before sending to the server. Even though I'm using the MVC wrappers, I can still wire-up the parameterMap feature using JavaScript. I did this for ONLY the "destroy" operation (for sending my IDs), but then the "read" operation no longer works when filtering, because my use of parameterMap overwrites what you are doing for "read".

If using the MVC wrappers and using server-side operation for the grid, can I still use the parameterMap feature for only "destroy", and not interfere with what you do with "read" ??

Hello,

With the MVC wrappers you can set parameters for every action separately using the .Data extension. The same approach is explained here:
