Question

I would like to allow users to scroll a DataGrid horizontally even if there are no row(s) in the DataGrid. Just to allow them to find out all the columns that exists in DataGrid. Is it possible to do?

I’m not sure if it is without redefining the template. I was able to get the scrollbar to show up (by accessing it directly) but not to actually scroll. I ended up going with the suggestion in a similar post of adding a dummy row and setting the row height to 0 when there are no rows. It’s ugly, but it works.

if (dtEnrollments.Rows.Count == 0)
{
    dtEnrollments.Rows.Add(dtEnrollments.NewRow());
    dgClassRoster.RowHeight = 0;
}
else
    dgRoster.RowHeight = defaultRowHeight;

dgRoster.ItemsSource = dtEnrollments.DefaultView;
