Dropdownlist select value to datasource

[David Blok]

Hi,

I'm trying to change the datasource value on change api of the dropdownlist.
Anyone have suggestion?

Code:

$("#ddllanguage").kendoDropDownList({
        ...
        change: DropdownChange
    });

var dropdownlist = $("#ddllanguage").data("kendoDropDownList");

function DropdownChange() {
        $("#technicalspecs").data("kendoListView").dataSource.read(); // RELOAD DATASOURCE ON KENDOLISTVIEW
    };

var dataSourcetechnical = new kendo.data.DataSource({
        transport: {
            read: {
                url: "/api/someurl",
                data: { languageid: dropdownlist.value() }, //HOW TO CHANGE THIS VALUE ON CHANGE EVENT
                dataType: "json"
            }
        }
    });

Hello David,

I can suggest using the schema.parse property of the Kendo UI DataSource to modified the response from the server:

I hope this will help you to achieve the desired result.

Hi,

Thanks for the reply. But i'm not don't fully understand the example.

How do i change the transport Data with parse after DropdownChange?

Hello David,

The schema.parse is allowing to change the received data from the dataSource.

If the desired result is to change the data on the server, this can be achieved using the data method of the DataSource:

http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#methods-data

If both are not applicable in your scenario could you please share with me more information about the desired result.
