Extend grid parameterMap in Asp MVC context

[Victor]

Hi!

I have a serverbound (ajax) grid and want to add a custom argument when fetching data.

After some searching I found the option to alter the parameterMap function. However, when I try to extend that function I extend the original functionality, not the one provided by kendo.aspnetmvc.js. This means that my custom argument works, but sort/filter/... does not anymore. When I remove my code sort/filter/... works but of course my custom data does not get through.

Is there any way to add my custom argument? Below is the code I tried for reference:

$("#myGrid").data("kendoGrid")

    .dataSource.transport.parameterMap = function (data, operation) {

        return $.extend(data, {

            myCustomData: true  //Actually client-side calculated data, not static

        });

    };

Thanks

Hello Victor,

 The officially supported way to send additional data is documented here.

Thanks so much for that, much better solution!

For others looking I after some digging found that it can also be configured on the dataSource like this

$("#myGrid").data("kendoGrid")

    .dataSource.transport.options.read.data = function (e) { ...}


Thanks again Atanas!
