LoadItems 事件

當控制項自訂重新編頁且需要更多資料時發生。

public event LoadItemsEventHandler LoadItems

備註

控制項是自訂重新編頁時，您可明確繫結控制項。重新編頁後，控制項引發此事件，指示所需的資料部份。應用程式可處理此事件，並且使用必要資料繫結控制項。

範例

下列範例示範如何截獲已重新編頁之 List 控制的 LoadItems 事件，在這個控制項中，使用者可指定要顯示在頁面上的項目數。

Sub loadNow(sender As Object, e As LoadItemsEventArgs)
   
   CType(myForm.Header.FindControl("label1"), System.Web.UI.MobileControls.Label).Text = "Maximum Item Allowed In " + "page is " + e.ItemCount.ToString()
   list1.Items.Clear()
   Dim arr As New ArrayList()
   
   ' Display items.
   Dim i As Integer
   For i = 0 To e.ItemCount
      arr.Add(e.ItemIndex)
   Next i
   list1.DataSource = arr
   list1.DataBind()

End Sub

<Mobile:Form runat=server id=myForm Paginate=true>
  <DeviceSpecific>
   <Choice>
      <HeaderTemplate>
         <Mobile:Label runat=server id=label1 
            StyleReference="title" />
      </HeaderTemplate>
   </Choice>
  </DeviceSpecific>
  <Mobile:List id="list1" runat=server ItemCount=2000
     onLoadItems ="loadNow"/>
</Mobile:Form>
</Script>

<script language="c#" runat="server">
void loadNow(object sender, LoadItemsEventArgs e)
{

   ((System.Web.UI.MobileControls.Label)myForm.Header.
      FindControl("label1")).Text = "Maximum Item Allowed In" +
      "page is " + e.ItemCount.ToString();
   list1.Items.Clear();
   ArrayList arr= new ArrayList();

   // Display items.
   for(int i = 0; i <= (e.ItemCount); i++)
   {
      arr.Add(e.ItemIndex);
   }
   list1.DataSource=arr;
   list1.DataBind();
}
