Hi Jared,
Thank you for your update.
Yes, you can show images in
the CaptionSummaryRow of the GridDataControl by using the Data Templates. You have
to set the template key in QueryCellInfo event and you cannot set in XAML. And
also, we already have sample for this in our dashboard, please check the sample
in the below location,
Sample Location Path: $Installation-directory\Syncfusion\EssentialStudio\10.2.0.56\WPF\Grid.WPF\Samples\3.5\GridDataControl\Summaries\Customizing
CaptionSummaryRow Demo\CS
For your reference, you can
download the sample in the below location,

Please let us know if you have
any queries.
Thanks,
