Inserting Data

This article is relevant to entity models that utilize the deprecated Visual Studio integration of Telerik Data Access. The current documentation of the Data Access framework is available here.

In this task, you will modify CRUDPage.html to support insert operations.

1. Open CRUDPage.html.

2. Configure the DataSource for remote Create operations. Note that the resource you will use is the same - /api/categories. However, the type of the operation is set to POST.

   var categoriesDataSource = new kendo.data.DataSource(
      {
          transport: {
              read: {
                  url: "/api/categories",
                  dataType: "json"
              },
   
              create: {
                  url: "/api/categories",
                  dataType: "json",
                  type: "POST"
              }
   
          },
          // schema configuration....
      });
   

3. Set the Kendo UI grid editable configuration option to popup. Additionally, to enable new records insertion the grid toolbar should be configured.

   $("#grid").kendoGrid({
      dataSource: categoriesDataSource,
      columns: [
          {
              field: "CategoryID",
              title: "Id"
          },
          {
              field: "CategoryName",
              title: "Name"
          },
          {
              field: "ImageFileName",
              title: "ImageUrl"
          }],
      toolbar: ["create"],
      editable: "popup"
   });
   

4. To test the HTML page, right-click CRUDPage.html in Solution Explorer and select View in Browser.

   

   The complete Javascript for the ready() event is listed below:

   $(document).ready(function () {
      var categoriesDataSource = new kendo.data.DataSource(
          {
              transport: {
                  read: {
                      url: "/api/categories",
                      dataType: "json"
                  },
                  create: {
                      url: "/api/categories",
                      dataType: "json",
                      type: "POST"
                  }
              },
              // schema configuration....
              schema: {
                  model: {
                      id: "CategoryID",
                      fields: {
                          CategoryID: {
                              editable: false,
                              nullable: false,
                              type: "number"
                          },
                          CategoryName: {
                              type: "string",
                              validation: { required: true }
                          },
                          ImageFileName: {
                              type: "string",
                              validation: { required: true }
                          },
                      }
                  }
              }
          });
      $("#grid").kendoGrid({
          dataSource: categoriesDataSource,
          columns: [
              {
                  field: "CategoryID",
                  title: "Id"
              },
              {
                  field: "CategoryName",
                  title: "Name"
              },
              {
                  field: "ImageFileName",
                  title: "ImageUrl"
              }],
          toolbar: ["create"],
          editable: "popup"
      });
   })
   

In the next tutorial, you will modify the CRUDPage.html so it supports update operations.
