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-first": "«",
            "text-last": "»",
            "text-previous": "‹",
            "text-next": "›",
            "text-total-pages": "pages",
            "text-total-records": "records",
            "sr-text-first": "First",

            "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"
              }
        }
    }
