Hi Tommy Mailhot,
Thanks for contacting Syncfusion support.
You can use getSelectedItems API to achieve your requirement which will return text, item and data . From that data, you can get ID of the selected list item, using the below code snippet.
|
listviewInstance.getSelectedItems().data["id"] |
We have prepared sample for your reference. Refer to the below sample.
Please let us know if you need any further assistance on this.
Thanks,
Karthick T
