85.                $("#menu").kendoMenu({dataSource: data });
86.            });
87.        });
88.    </script>
89.</html>

 

In the following example , there are the following problems:

  1. The delete button does not ask for confirmation. PUT generates rather than a DELETE.
  2. When updating generates a PUT rather than POST .
  3. If I remove <kendo:dataSource-transport-create> nothing works .​ Only GET (READ)
  4. <kendo:dataSource-transport-parameterMap>​ I've also moved from after the last <kendo:dataSource-transport-...> site and has the same behavior.

I 'm testing with the trial version .

Thank you for any help.​

 update: {
                        url: "api/salas", dataType: "json", type: "POST",
                        complete: function(e) {
                            $("#grid").data("kendoGrid").dataSource.read();
                        }  
                    },

What is the equivalent in ASP? this is what is wrong with me ..

Hi Lucas,

I would recommend subscribing to the DataSource's requestEnd event instead. The same could also be achieved by using a Custom DataSource and specifying the functions for CRUD operations manually. For example: 
.DataSource(dataSource => dataSource       
    .Custom()   
    .Transport(transport =>
    {
        transport.Read("GridRead"); //JavaScript function which performs the Ajax request and its event handling
        transport.ParameterMap("parameterMap");
    })
)
