Hello,

We have created this new thread for you in reference to your question at the following one:
https://es.infragistics.com/community/forums/f/ultimate-ui-for-wpf/107252/how-to-add-contents-of-2-fields-to-get-summary-in-xaml-code

This way you can keep track of the separate issues depending on their specific context.

Would you please provide me with more detailed information on what you mean by saying row and column summaries when using the XamReportViewer? It would be great if you could provide me with a sample, which contains the current implementation of the functionality you are trying to achieve. Having this information will help me further investigate this matter for you.
