スクリプトには、次のような列がいくつかあります。

  <script>
  $("#grid").kendoGrid({
              height: 400,
              columns: [
                 "ProductName", 
                 { field: "UnitPrice", format: "{0:c}", width: "150px" },
                 { field: "UnitsInStock", width: "150px" },
                 { field: "Discontinued", width: "100px" },
                 { command: "destroy", title: "Delete", width: "110px" }
              ]
  });
  </script>

ジェネリックとチェーンを使用して拡張メソッドを記述したいのですが、c# で次のようなものが必要です。

   <% Page.Grid<Product>()
     .Columns.Add(c=> {
       c.add("ProductName").Title("Product Name");
       c.add("UnitPrice").Title("Unit Price").Width("150px");
     }).Render(); %>

C# メソッド拡張を記述する方法 このメソッドを asp.net 形式で使用する必要があります。

私はついに自分の答えを見つけました：

Kend._2013.Extension.KendoGrid<string>.Name("KendoGrid1")
                                          .Columns(c => new Kend._2013.Extension.Column[]
                                          {                                                                                   
                                                c.Add("ProductID").Title("ID").Width(100),
                                                c.Add("ProductName").Title("Name").Width(150),
