     How does the selection and pagination of search results work?

    Users can optimize the number of search items per page by selecting a value from the Items Per Page drop-down; this number ranges from 10 to 50 per page. The default number is 20.

    The selected number of search items is displayed in the grid below the drop-down.

    The search items per page can be changed and viewed at any time for the user's convenience.

    The search results are listed on multiple pages according to the selected number of Items Per Page in the drop-down, if the total number of search items resulting from the search criteria exceeds the selected number of items per page.

    The user can also directly jump to another page of the search results grid by clicking its corresponding link above the search results grid.

    The Selection drop-down in the left of the header row has four selection options: None, Some, Page, and All.

    This Selection drop-down is present on pages in which users need to select multiple search items for use such as viewing, modifying, etc.

    The Selection drop-down options perform the following functions:

    ColumnDescription
    NoneAll items in the list across all pages of the search results grid are deselected.
    Page

    All items on the currently visible page of the search results grid are selected.

    If you move to another page of the search results grid, you will see that none of the items on that page are selected, but the items selected on the earlier page are still retained.

    Some

    This selection appears when you manually select a few items from the list by selecting their corresponding check boxes. This selection also appears if you select Page from the drop-down and then increase the Items per page, or if you select All from the drop-down and then deselect any item on the search results page.

    It is also possible to select items across multiple pages of the search results grid by simply making the selection on one page and moving on to another - the item selection made on the earlier page is retained even if you move to another page to make additional selections.

    All

    All items in the list across all pages of the search results grid are selected.

    Even when moving to any other page of the search results grid, all the items on that new page are also selected.

    The selection drop-down remains as All if any of the items are not deselected, and it changes to Some if any of the items on any of the pages of the search results grid are deselected. Furthermore, if the deselection is made on the first page of the search results grid, then all the items on other pages are deselected. However, if you move to another page of the search results grid while the selection drop-down is All and deselect any item, the selection drop-down for that page changes to Some, while all items on the remaining pages remain selected with the selection drop-down selection showing as Page on those pages.
