Set All Page Size in Grid for ASP.NET Core

Environment

Product	Progress® Telerik® UI Grid for ASP.NET Core
Product Version	2017.2.621

Description

How can I use an All page size in the Kendo UI Grid in ASP.NET Core projects?

Solution

After the document is ready, dynamically add the option for the All page size through the dataSource of the DropdownList to allow for selecting the page size.

        $(function () {

            var grid = $('#grid').data('kendoGrid');
            var pageSizeDropDownList= grid.wrapper.find('.k-pager-sizes').find('[data-role="dropdownlist"]').data('kendoDropDownList');
            console.log(pageSizeDropDownList)
            pageSizeDropDownList.dataSource.add({text:"All", value:'all'})
            pageSizeDropDownList.dataSource.sync()      
        })

Notes

This approach allows you to customize the text inside the drop-down list.
