Hello,

It has been a while since you have made your post, in case you still need support I will be glad to assist you further. I suppose the other community members can benefit from this answer as well. I have been looking through your post and I suggest you use the following code in your XamDataGrid’s RecordActivating event:

DataRecordPresenter drp =  DataRecordPresenter.FromRecord(e.Record) as DataRecordPresenter;
ContentPresenter cp = Utilities.GetDescendantFromName(drp, "PART_RecordContentSite") as ContentPresenter;
if (!cp.IsMouseOver)
{
    e.Cancel = true;
}

Feel free to write me if you have further questions.
