title: Alternative to DataSourceRequest
body: <p>There is <code>DataSourceRequest</code> class in KendoUI framework. It has <code>Filters</code> collection that allows to get filtering <code>Expressions</code> for each filter configured in grid. Is there alternative class to <code>DataSourceRequest</code> that contains all the grid data in "plain", not parsed format, without ability to build expressions but with all the form data "as is"?</p>
