Update datasource?

[Kyle]

I have a datasource/grid that I would like to update depending on selected in a TreeView.

I have my datasource created like so:

        dataSource = new kendo.data.DataSource({
            transport: {
                read: {
                    url: "/api/items",
                    dataType: "json",
                    data: { id: "1" }
                }
            }
        });

When a user selected an item on the TreeView I want to update the datasource to change the id that defines its results. Can I just create a new dataSource with the new {data: {id: "newid"}}?

How would I then apply this to the grid that already exists?

Hi Kyle,

You may change a parameters defined through the transport's operation data by assigning a function which to return the updated value. Please refer to this online demo for more details. Note the q parameter's definition.

All the best,
