  • Demo_Base

  • These forms will allow you to modify the properties for this object.

  • Pagination

  • -

  • Demo_Base

  • Often a long list of items are to numerous to fit on one page. Pagination breaks up the items into manageable chunks.

  • Properties

  • Show Pagination: Info

  • Paginate

  • The number of items is typically at least 10 up to 200 items.

  • Pages: Provide a direct link to a particular page and links to the next/previous page that allow 'stepping' through the pages. If there are more pages than this default, a 'Next Page' link will be displayed. This prevents large recordsets from creating too many links.

  • Rows: Shows this many rows in the grid. The number of items is typically at least 10 up to 200 items. A smaller number will return results to the browser faster.

    • Rows per Page Listbox:

  • Style

  • Hide unavailable links: The "previous/next" or "start/end" are only shown when there is a page to navigate to.

  • VCR - Display with controls that resemble buttons on VCR's or remote controls.

    •       1 2 3 4 5      

    • Page Numbering: Pages.

      • Current Page: Current page is displayed between the images.

      • Current Page in the center: Current page will remain centered between pages.

      • Current Page moving: pages will remain staticly displayed at one time. The "next" or "previous" navigation must be clicked to get the next set of pages.

      • Totals: Show the total number of items and use a title to say what kind of items they are.

      • Enlarged Click Area: Summarize the results (e.g. '11-20 21-30') - Depending on the font size for the page numbers, the size of the page number is quite small and therefore hard to click on. The downside of this is that you may run out of space when there are too many items.

      • Jump To: When there are many pages of items that could all be meaningful to users, e.g. a list of emails, the list of page numbers can become too long. In that case, consider adding an edit-box that allows users to type in the page number directly.

  • Numerical: Numbered text links.

  • Rolodex: Alphabetical text links.

  • HTML Button: Form controls created by the browser.

  • Custom:

  • Placement

  • The navigation bar tells the users the most important information about the list; how many items there are, how many they see now and how to get to the rest. By placing the navigation above AND below the list they always have access to the navigation even when scrolling through the current page.

  • Above: Place Pagination above the grid.

  • Below: Place Pagination below the grid.

  • Above and Below: Show navigation of the pages above and below the list of items. This makes it easy to go to the next page, because navigational links are positioned to minimize having to scroll back to the top of the page for navigaiton.
