Is there a good way to tell how many items are visible at a
given point in a datagrid. For example I would like to have a
header that says: viewing items 4-8 of 23. I'm able to get the
total count, and that you are at position 4 though the scroll
location, however I cannot find any properties that tell me how
many items are viewable at that time. If anyone knows of a way to
approach this that would be great!
