Hi, I am sure I am missing the obvious but...

 

Is there a way to obtain the current parameter values from a reportViewer on the client (html) side?

I have a report viewer that works along side a menu that offers several reports that are fundamentally related and all share the same parameters.  When the user makes a change (for example the date range), and then chooses one of the other reports, I want to ensure the same date range is pre-selected.

Is this possible? or do I have to supply my own parameter controls and steal the values from that, seems a lot of work in comparison to just having access to a collection of current parameter values, something like ..

 

var viewer = $("#reportViewer1").data("telerik_ReportViewer");
var currentParams = viewer.reportSource.parameters;

viewer.reportSource( { 

                                report: reportDefinition
                                , parameters: currentParams
                            });

Many thanks

Hello krisdoff,

You can get the parameters already assigned to the client reportSource by calling reportSource() that will return an object with properties 'report' and 'parameters'.
The code would rather look like:
var viewer = $("#reportViewer1").data("telerik_ReportViewer");
var currentParams = viewer.reportSource().parameters;

Check this article for details.

Note that reportSource(rs) (i.e. the same function with an argument) would assign new values to the client reportSource.
