Hi.

I'm using grid and I can't find a normal solution to execute some code after successful item update on the server.
var ds = new kendo.data.DataSource({
 
  transport: {
        read: {
            url: 'stations',
            dataType: 'json'
               },
         update: {
            url: 'stations',
            dataType: 'json',
             type: 'PUT'
            },
         destroy: {
           url: 'stations',
           dataType: 'json',
             type: 'DELETE'
        },
        create: {
          url: 'stations',
           dataType: 'json',
            type: 'POST'
         },
     parameterMap: function (data, operation)
       {
          if (operation !== "read" && data)
          {
              return JSON.stringify(data);
           }
        }
   },
   batch: false,
 
    schema: {
         model: {
             id: "Id",
                 fields: {//some fields... }
 
                    }
                }
            });

The most obvious solution to me was to use update function with ajax (as in documentation samples). But it doesn't work. There are some work arounds on SO I found, but they seems not  good to me. Handling grid save event is not useful because it is raised before server update. Also I tried to use requestEnd event on ds, but it is not obviouse how to differentiate success and error request. And the more important thing is that I have no access to updated item in the requestEnd handler.

So the question: is there some mechanisms to execute some js code with updated item after successful server update within grid?

If it is important, I use angular-kendo.

Thanks in advance.

Hello Jose,

If there is error, the error event of the dataSource will be triggered. Inside the requestEnd event you have access to the response so if you have returned the updated item from the server then you should have it available.

Thank you!

It was obvious solution, but in my API I returned object id after it was updated instead of object. It is good idea to return object.

Thanks again.
