Thank you for contacting Syncfusion support.
We have analyzed your query. In SfDataGrid.SelectedItems is a collection property, so whenever the SelectedItems collection is changed, the property bound with SelectedItems does not get notified for this change. However, you can achieve this by creating an attached property for SelectedItems. And SfDataGrid’s SelectedItems values are set to the attached property by handling SelectedItems.Collectionchanged event. For your reference, we have attached the KB link. Could you please refer to it.
