尋呼無法在我的Telerik Grid中工作

Question

我正在研究當前與尋呼有關的問題。網格填充到它有15個項目的地步。這是最大頁面大小，但是，頁面不會被添加。我不完全確定它爲什麼不添加頁面。以下是我的代碼。

var gridPageSize = EngineContext.Current.Resolve<Nop.Core.Domain.Common.AdminAreaSettings>().GridPageSize; 
    <table class="adminContent"> 
     <tr> 
      <td>

        .Name("categoryunits-grid")

        { 
         keys.Add(x => x.Id); 
         keys.Add(x => x.CategoryId); 
         keys.Add(x => x.UnitId); 
        }) 
        .DataBinding(dataBinding => 
        { 
         dataBinding.Ajax() 
          .Select("CategoryUnitsList", "Category", new { categoryId = Model.Id })

任何幫助將不勝感激。謝謝大家。

沒關係，我想通了這個問題。在我的Controller中，當綁定網格時設置Total時，我使用綁定到Model的數據的計數，而不是實體帶回的總數。
