I have a number of regular MVC grids that make their requests to controllers with additional data, and they make use of the Data attribute to call a function which returns an object. For example:

@(Html.Kendo().Grid<Model>()
                .Name("Grid")
                .DataSource(dataSource => dataSource
                    .Ajax()
                    .ServerOperation(true)
                    .Read(read => read
                        .Action("ActionName", "ControllerName")
                        .Data("FunctionName")
                    )
                )

...and this works fine, but for the PivotGrid I can't seem to find a matching equivalent. The configuration seems to be quite different in fact:

@(Html.Kendo().PivotGrid<Model>()
                .Name("pivotGrid")
                .DataSource(dataSource => dataSource
                    .Ajax()
                    .Transport(transport => transport
                        .Read("Action", "Controller")
                    )
                    .Events(ev => ev.RequestEnd("onRequestEnd").RequestStart("onRequestStart"))

I cannot seem to use the same configuration (Transport instead of Read), and I cannot find anywhere the "Data" action can be assigned. I can set this attribute to the relevant javascript function after page load using:

$("#pivotGrid").data('kendoPivotGrid').dataSource.transport.options.read.data = pivotSync;

...but I would like to be able to set this during the initial configuration of the pivot grid. Is this possible?

Hello,

The Data method should work as expected since the PivotDataSource does inherit from the DataSource object, which provides the data function. 

Actually I did modify the DataSource configuration for our PivotGrid / Remote binding demo as shown below: 

.DataSource(dataSource => dataSource
        .Ajax()
        .Transport(transport => transport.Read(read => read.Action("Customers_Read", "PivotGrid").Data("test")))
<script>
    function test() {
        return {
            test: "test"
        }
    }
</script>

and it worked fine. The test: test was sent along with the request to the server.

I have tried this, and get the following error:

 

Compiler Error Message: CS1061: 'PivotAjaxDataSourceTransportBuilder' does not contain a definition for 'Data' and no extension method 'Data' accepting a first argument of type 'PivotAjaxDataSourceTransportBuilder' could be found (are you missing a using directive or an assembly reference?)
