I have a WPF application using MVVM. I have some user controls that show some SSRS reports in a ReportViewer control hosted within a windows forms host control.
The User Control has a simple combobox where the user selects a criteria and therefore the report satisfying this criteria will be loaded, its data fetched from the database and then the report is shown to the user.
What is the best approach to implement such scenario in WPF using MVVM?
Look at this answer
He is creating the WindowsFormsHost and ReportViewer in the ViewModel
WindowsFormsHost windowsFormsHost = new WindowsFormsHost(); reportViewer = new ReportViewer(); windowsFormsHost.Child = reportViewer; this.Viewer = windowsFormsHost and then using a ContentPresenter to display it
<ContentPresenter Content="{Binding Viewer}" /> 
System.Windows.Forms.Integration.WindowsFormsHost type
Unfortunately, there is no native WPF Report Viewer control with similar functionality and there will not be one in .Net 4.0 (according to Jamie Rodriguez at Microsoft).
