Dgrid update data store

Question

I am using DGRID to display data. I am aware i can query records in the store using store.query and insert records into the store using store.put and so on however i would like to do an update of the store. How can i update a record in the store?

I would prefer updating the memory store and then push that back into the database instead of updating the database first and then refreshing the memory store.

Data

 var data = [
            { id:"1", idType: "Passport", idNumber: "12121545WWW" },
            { id:"2",idType: "Drivers Permit", idNumber: "11212154515 FF"},
            { id:"3",idType: "Electoral Identification", idNumber: "425123123121"}
        ];

Functions

Add data

Store.put({id: enteredId, idNumber:enteredIdNumber,idType:enteredIdType})

Query data

Store.query({idType: enteredIdType})

Update data - i am confused how this is done

Store.update({idNumber:enteredIdNumber,idType:enteredIdType})

You seem to be a bit confused about the dojo/store API.

store.add(item) is used to add new items
store.put(item) is used to update items, but can often also be used to add new ones with a specific ID
store.remove(id) is used to delete items

If you wrap your store with dojo/store/Observable, e.g. new Observable(new Memory({ data: ... })), then the grid will update automatically when add / put / remove are called.

See the dojo/store documentation for more information.

If you are wondering how to update records via the grid itself, have a look at the editor column plugin.
