Sorry, I don't think I understood the question. There is already a control above and below the results grid that allows you to jump through pages, but you probably mean something else. Can you please clarify? Thank you!
I could simply be missing it, but I mean that I can't jump to specific pages. In the following example (https://i.imgur.com/ebIIx5o.png), I am on page 5. How do I jump to page 110? Thank you.
I see what you mean now, thanks for the explanation. The result grid along with the pagination area are all part of an off-the-shelf user control that I am using on the site, and off the top of my head I can't think of a way to customize it to add a free form input for page number. I will look though, stay tuned.
