Changing in runtime the transport of a custom dataSource

[Peter]

Hi there,

 

I'm creating a custom datasource

01.@(Html.Kendo().Grid<Foo>()
02.    .Name("grid")
03.    .AutoBind(false)
04.    .DataSource(dataSource => dataSource
05.       .Custom()
06.       .Batch(true)
07.       .Schema(s =>
08.         s.Model(model =>
09.         {
10.            model.Id(p => p.ID);
11.            model.Field(x => x.ID).DefaultValue(0);
12.         })
13.       )
14.       .Transport(new
15.       {
16.          read = new Kendo.Mvc.ClientHandlerDescriptor() { HandlerName = "customRead" },
17.          create = new Kendo.Mvc.ClientHandlerDescriptor() { HandlerName = "customCreate" },
18.          update = new Kendo.Mvc.ClientHandlerDescriptor() { HandlerName = "customUpdate" },
19.          destroy = new Kendo.Mvc.ClientHandlerDescriptor() { HandlerName = "customDestroy" },
20.       })
21.    )
22.)

 

I need in runtime to change all the transport's handlers (in JavaScript).

I've read the documentation and some posts in the forum but I can't make it work. The last thing I tried was this

 

01.function anotherDestroy(e) {
02.    console.log("calling anotherDestroy()");
03.}
04.
05.let ds =
06.    $("#grid")
07.        .data("kendoGrid")
08.        .dataSource;
09.
10.ds.transport.options.destroy = anotherDestroy;

 

Can someone please tell me what I'm doing wrong?

Thank you.

Hello Peter,

In this scenario, I can suggest using the setOptions method of the Grid to programmatically changed the transport option of its dataSource.

http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#methods-setOptions

I made an example demonstrating how to change the dataSource transport.read.URL dynamically. It will require the jQuery syntax when the new options are passed, the same approach can be used in the provided MVC Grid:
