Custom function call from Grid Update event

[Naga]

is it possible to call a Jquery/Javascript function from an update ​section of a grid ?

 i want to perform some actions before calling the controller method, My code looks like below. Please help me

        dataSource: new kendo.data.DataSource({
            transport: {
                read:  {
                    url: crudServiceBaseUrl + "/Products",
                    dataType: "jsonp"
                },
                update: {
                    url: crudServiceBaseUrl + "/Products/Update",                                     // instead of URL i want to  call a custom Javascript function here
                    dataType: "jsonp"
                },

            },​

Hello Naga,

What you want to do is indeed possible, you just have to subscribe to the requestStart event during initialization and then check that the type of the request is actually update instead of read, create, or destroy. You code would look as such: 

01.dataSource: new kendo.data.DataSource({
02.            transport: {
03.                read:  {
04.                    url: crudServiceBaseUrl + "/Products",
05.                    dataType: "jsonp"
06.                },
07.                update: {
08.                    url: crudServiceBaseUrl + "/Products/Update",
09.                    dataType: "jsonp"
10.                },
11.            },​
12.            requestStart: function(e) {
13.                if (e.type == "update") {
14.                    //YOUR LOGIC GOES HERE
15.                }
16.            }

Hope this helps!
