The WPF Report Is Messed Up or Different from Design-Time Preview

Environment

Product	Progress® Telerik® Reporting
Version	Q2 2012 and later
Report Viewers	WPF

Description

The report in the WPF ReportViewer is messed up or is different from the design-time preview.

Cause

The WPF ReportViewer displays the rendered report in XAML format, so external styles may affect the produced XAML that contains standard elements like Canvas, TextBlock, and more.

Solution

Try to exclude styles to check if they change the displayed content. Alternatively, try to export the report in a format like PDF.
