can't render more than one report at a time

[Joe]

I have an app that requires me to display four reports simultaneously. But it blows up while rendering the second report, because, I believe, the first report is still rendering.
I looked at code to access the IsInProgress property, but this requires me to include a reference to telerik.reportviewer.wpf.dll, which this silverlight project does not allow.

I should mention that the four reports are all the same underlying report using different parameters.

I believe I could simply define four distinct reports to get around this, but is it possible to otherwise determine when one report is done rendering and then begin the next?

I cannot define four different reports, I need to either know when the report viewer has finished rendering or get some advice on how to make the report viewer reentrant.

Hello Joe,

There is no out of the box solution to your scenario. However it is possible to get the rendering completion event from the service client of a report viewer and trigger the next viewer rendering. Find attached a simple page with four report viewers demonstrating that approach.

We will consider providing such functionality in the future.
