Hello,

I'm trying to refresh my reportviewer so it can reload parameters values.
How to do that using MVVM in a Silverlight project ? It seems that no refresh method exists on report viewer control...

Thanks.

I guess RefreshReportCommand Property is what you're looking for.

It works fine for me. If you're still having problems opening the link, simply locate that property in the Telerik Reporting API (http://www.telerik.com/help/reporting/overview.html).

Yes the link works this morning... don't know why...
I had a look to this property but i can't see how to link this ReportViewerModel to the ReportViewer control.
Do you have any example using this RefreshReportCommand ?

Thank you.

Here is dummy code:

var model = (ReportViewerModel)this.ReportViewer1.DataContext;
model.RefreshReportCommand.Execute();

Thanks this should work fine but I'm using MVVM, so I have to refresh my report in the ViewModel, not in the code-behind of the View...
Any ideas on how to do that ?

Hi Equipe Info,

There is a possible solution described in your other support thread: RenderBegin method using Trigger.  Please, take a look at and let us know whether it fits in your case.

Best wishes,

Hi,

Yes I had a look to my previous thread and it gives a solution for those who don't use MVVM.
But in our case we need MVVM...
I will mark it as answered but it's not what we were looking for.

Thanks
