PivotGrid in Razor Pages

Razor Pages is an alternative to the MVC pattern that makes page-focused coding easier and more productive. This approach consists of a cshtml file and a cshtml.cs file (by design, the two files have the same name).

You can seamlessly integrate the Telerik UI PivotGrid for ASP.NET Core in Razor Pages applications.

This article describes how to configure the PivotGrid component in a Razor Pages scenario.

Getting Started

The PivotGrid component provides a convenient integration with the Grid and DataSource. This example will demonstrate how to configure them in a Razor Pages scenario so that the PivotGrid appear at the top of the Grid.

1. Create the Grid, DataSource and PivotGrid definitions.

   HtmlHelper_Index.cshtml

       @page
       @model IndexModel
       @using Kendo.Mvc.UI
   
       <div class="k-pivotgrid-wrapper">
          @(Html.Kendo().PivotConfigurator()
              .Name("configurator")
              .Filterable(true)
              .Height(500)
          )
       
          @(Html.Kendo().PivotGrid<CustomerViewModel>()
              .Name("pivotgrid")
              .Configurator("#configurator")
              .ColumnWidth(120)
              .Filterable(true)
              .Height(500)
              .DataSource(dataSource => dataSource
              .Ajax()
              .Transport(transport => transport.Read(r => r.Url("/Index?handler=Read").Data("forgeryToken")))
                  .Schema(schema => schema
                      .Cube(cube => cube
                          .Dimensions(dimensions => {
                              dimensions.Add(model => model.ContactName).Caption("All Contacts");
                              dimensions.Add(model => model.CompanyName).Caption("All Companies");
                              dimensions.Add(model => model.Country).Caption("All Countries");
                              dimensions.Add(model => model.ContactTitle).Caption("All Titles");
                          })
                          .Measures(measures => measures.Add("Contacts Count").Field(model => model.CustomerID).AggregateName("count"))
                      ))
                  .Columns(columns =>
                  {
                      columns.Add("Country").Expand(true);
                      columns.Add("CompanyName");
                  })
                  .Rows(rows => rows.Add("ContactTitle").Expand(true))
                  .Measures(measures => measures.Values("Contacts Count"))
              )
          )
       </div>

   TagHelper_Index.cshtml

       @page
       @model IndexModel
       @using Kendo.Mvc.UI
   
       <div class="k-pivotgrid-wrapper">
           <kendo-pivotdatasource type=@(PivotDataSourceType.Ajax) name="pivotSource">
               <columns>
                   <pivot-datasource-column name="Country" expand="true"></pivot-datasource-column>
                   <pivot-datasource-column name="CompanyName"></pivot-datasource-column>
               </columns>
               <rows>
                   <row name="ContactTitle" expand="true"></row>
               </rows>
               <schema type="json">
                   <cube>
                       <dimensions>
                           <dimension name="ContactName" caption="All Contact" />
                           <dimension name="CompanyName" caption="All Companies" />
                           <dimension name="Country" caption="All Countries" />
                           <dimension name="ContactTitle" caption="All Titles" />
                       </dimensions>
                       <measures>
                           <measure name="Contacts Count" field="CustomerID" aggregate="count" />
                       </measures>
                   </cube>
               </schema>
               <measures values='new string[] {"Contacts Count"}'></measures>
               <transport>
                   <read url="/Index?handler=Read" data="forgeryToken" datatype="json" content-type="application/json" type="POST" />
               </transport>
           </kendo-pivotdatasource>
       
           <kendo-pivotconfigurator name="configurator" datasource-id="pivotSource" filterable="true" height="570">
           </kendo-pivotconfigurator>
       
           <kendo-pivotgrid name="pivotgrid" column-width="120" datasource-id="pivotSource" filterable="true" height="570">
           </kendo-pivotgrid>
       </div>

2. Add an AntiForgeryToken at the top of the page.

   Razor

       @inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
       @Html.AntiForgeryToken()

3. Send the AntiForgeryToken with the Read request.

   Razor

       <script>
           function forgeryToken() {
               return kendo.antiForgeryTokens();
           }
       </script>

   Additional parameters can also be supplied.

   Razor

       <script>
           function forgeryToken() {
               return {
                   __RequestVerificationToken: kendo.antiForgeryTokens().__RequestVerificationToken,
                   additionalParameter: "test"
               }
           }
       </script>

4. Within the cshtml.cs file, add a handler method for the Read data operation.

   Index.cshtml.cs

       public static IList<CustomerViewModel> customers;
   
       public void OnGet(string culture)
       {
           if (!String.IsNullOrEmpty(culture))
           {
               CultureInfo.DefaultThreadCurrentCulture = CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo(culture);
           }
   
           if (customers == null)
           {
               customers = new List<CustomerViewModel>();
   
               Enumerable.Range(1, 50).ToList().ForEach(i => customers.Add(new CustomerViewModel
               {
                   CustomerID = "CustomerID " + i,
                   CompanyName = "CompanyName " + (i % 3),
                   ContactName = "ContactName " + i,
                   ContactTitle = "ContactTitle " + (i % 7),
                   Country = "Country " + (i % 3)
               }));
   
           }
       }
   
       public JsonResult OnPostRead([DataSourceRequest] DataSourceRequest request)
       {
           return new JsonResult(customers.ToDataSourceResult(request));
       }

   Model

      public class CustomerViewModel
      {
          public string CustomerID { get; set; }
          public string CompanyName { get; set; }
          public string ContactName { get; set; }
          public string ContactTitle { get; set; }
          public string Country { get; set; }
      }
