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 “Yes” version 10.3 support this, so I suggest you use the following code in order to iterate trough the XamDataGrid’s Records and set their height:

foreach (var item in xamDataGrid1.Records)
{
    DataRecordPresenter.FromRecord(item).Height = 50;
}

Feel free to write me if you have further questions.
