Change page size

Default page size is 10, it can be changed to any other number. When a differet page size is used we have to specify the query string key name for page size parameter.

  • page-size-nav-block-size : The block size for the dropdown items.
  • page-size-nav-max-items : How many items to display in the dropdown.
HTML Code

    <paging total-records="Model.TotalRecords"
            page-no="Model.PageNo"
            page-size="Model.PageSize"
            max-displayed-pages="5"
            page-size-nav-block-size="15"
            page-size-nav-max-items="5">
    </paging>
Result
85 pages841 records

Query String Key Names

Current page number and page size values are added to the query string by the keys "P" and "S".
e.g. /index?p=1&s=10.

To change the query string key names use below attributes:

  • query-string-key-page-no : key name for page number. default is "p".
  • query-string-key-page-size : key name for page size. default is "s".
HTML Code

    <paging total-records="Model.TotalRecords"
            page-no="Model.PageNo"
            page-size="Model.PageSize"
            max-displayed-pages="5"
            query-string-key-page-no="pageNo"
            query-string-key-page-size="pageSize">
    </paging>
Result
/index?pageNo=1&pageSize=10

Json Settings

All default settings can be overrided in appsettings.json file and it will affect all paging tag helpers in the application. Any settings defined inside the tag helper will override the default and json settings.

the default json settings can be overrided in appSettings.json, below is a full list of all settings in json format:


{
    "lazziya": {
        "pagingTagHelper": {
          "default": {
            "page-no": 1,
            "page-size": 10,
            "total-records": 0,
            "max-displayed-pages": 10,
            "gap-size": 3,
            "page-size-nav-block-size": 10,
            "page-size-nav-max-items": 5,
            "query-string-key-page-no": "p",
            "query-string-key-page-size": "s",
            "show-first-last": true,
            "show-prev-next": true,
            "show-page-size-nav": true,
            "show-total-pages": true,
            "show-total-records": true,
            "show-first-numbered-page": true,
            "show-last-numbered-page": true,
            "text-page-size": "Page size",
            "text-first": "«",
            "text-last": "»",
            "text-previous": "‹",
            "text-next": "›",
            "text-total-pages": "pages",
            "text-total-records": "records",
            "sr-text-first": "First",
            "sr-text-last": "Last",

            "class-info-div": "col-2",
            "class-page-size-div": "col-2",
            "class-paging-control-div": "col-8",
            "class-paging-control": "pagination",
            "class-active-page": "active",
            "class-disabled-jumping-button": "disabled",
            "class-total-pages": "badge badge-secondary",
            "class-total-records": "badge badge-info"
          }
        }
    }
}

More than one settings collection can be defined inside appSettings.json file, so each paging helper element can read settings from different collection.

it is not necessary to override all the settings inside json file, it is possible to mention only the settings we want to override.

e.g. below there is two settings collections "basic" and "custom", each can be applied to different set of paging helpers inside your application.


{
    "lazziya": {
        "pagingTagHelper": {
            "basic": {
                "show-first-last": true,
                "max-displayed-pages": 7,
                "class-active-aage": "disabled"
              },
              "custom": {
                "show-first-last": true,
                "show-prev-next": true,
                "show-first-numbered-page": true,
                "show-last-numbered-page": true,
                "max-displayed-pages": 2,
                "text-first": "go first",
                "text-last": "go last",
                "text-previous": "one step back",
                "text-next": "one step forward",
                "class-paging-control": "pagination pagination-lg"
              }
        }
    }
