Hello,
we've upgraded to VS2022 and .NET 7.
The reports are giving us a lot of problems, it looks like we have too rebuild them in the Standalone Report Designer. Import fails
The default Telerik WPF ReportViewer has this
<tr:ReportViewer Grid.Row="0" x:Name="ReportViewer1" HorizontalAlignment="Stretch" EnableAccessibility="true">
<tr:ReportViewer.ReportSource>
<telerikReporting:UriReportSource Uri=""/>
</tr:ReportViewer.ReportSource>
</tr:ReportViewer>
Can we change the Uri programmatically in a MVVM project? Something like
<tr:ReportViewer Grid.Row="0" x:Name="ReportViewer1" HorizontalAlignment="Stretch" EnableAccessibility="true">
<tr:ReportViewer.ReportSource>
<telerikReporting:UriReportSource Uri="{Binding ReportSource}"/>
</tr:ReportViewer.ReportSource>
</tr:ReportViewer>
where reportsource is ExampleReport.trdp

Figured it out.
In the viewmodel I create the InstanceReportSource using
public static readonly PropertyData ReportSourceProperty = RegisterProperty("MyReportSource", typeof(InstanceReportSource));
public InstanceReportSource MyReportSource { get { return GetValue<InstanceReportSource>(ReportSourceProperty); } set { SetValue(ReportSourceProperty, value); } }
public ReportWindowViewModel(List<TargetGroupItem> targetGroupItem)
{
var reportPackager = new ReportPackager();
var reportProcessor = new ReportProcessor();
Telerik.Reporting.Report report = null;
using (var sourceStream = System.IO.File.OpenRead(AppDomain.CurrentDomain.BaseDirectory + "/Reports/CustListComment.trdp"))
{
report = (Telerik.Reporting.Report)reportPackager.UnpackageDocument(sourceStream);
}
report.DataSource = targetGroupItem;
MyReportSource = new InstanceReportSource() { ReportDocument = report };
And in the view
<Grid x:Name="LayoutRoot">
<Grid Margin="20" >
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<tr:ReportViewer Grid.Row="0" x:Name="ReportViewer1" HorizontalAlignment="Stretch" EnableAccessibility="true"
ReportSource="{Binding MyReportSource}">
</tr:ReportViewer>
</Grid>
</Grid>
I use the Catel framework for handling the INotifyPropertyChanged
