我有一個按鈕(Bearbeitung_Click)來禁用/啓用我的列表視圖,它具有批量行內編輯。這是這樣,它並不總是可編輯的。我希望LayoutTemplate中的DataPager始終處於啓用狀態,以便即使在禁用編輯時,用戶仍可以瀏覽頁面。禁用列表視圖時,在列表視圖中啓用分頁。 ASP.NET C#

我對含有DataPager的模板的.aspx代碼:

<LayoutTemplate> 
      <table runat="server"> 
       <tr runat="server"> 
        <td runat="server"> 
         <table ID="itemPlaceholderContainer" runat="server" border="1" 
          style="background-color: #FFFFFF;border-collapse: collapse;border-color: #999999;border-style:none;border-width:1px;font-family: Verdana, Arial, Helvetica, sans-serif;"> 
          <tr runat="server" style="background-color: #E0FFFF;color: #333333; font-size:smaller;"> 
           <th runat="server"> 
            </th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
           <th runat="server"> 
            Example</th> 
          </tr> 
          <tr ID="itemPlaceholder" runat="server"> 
          </tr> 
         </table> 
        </td> 
       </tr> 
       <tr runat="server"> 
        <td runat="server" 
         style="text-align: center;background-color: #5D7B9D;font-family: Verdana, Arial, Helvetica, sans-serif;color: #FFFFFF"> 
         <asp:DataPager ID="DataPager1" runat="server" Enabled="true"> 
          <Fields> 
           <asp:NextPreviousPagerField ButtonType="Button" ShowFirstPageButton="True" 
            ShowNextPageButton="False" ShowPreviousPageButton="False" /> 
           <asp:NumericPagerField /> 
           <asp:NextPreviousPagerField ButtonType="Button" ShowLastPageButton="True" 
            ShowNextPageButton="False" ShowPreviousPageButton="False" /> 
          </Fields> 
         </asp:DataPager> 

        </td> 
       </tr> 
      </table> 
     </LayoutTemplate> 

我的代碼背後的按鈕,並改變頁面大小爲:

protected void PageSize_Changed(object sender, EventArgs e) 
    { 
     DataPager pager = ListView1.FindControl("DataPager1") as DataPager; 
     if (string.IsNullOrEmpty(tb_page.Text) || tb_page.Text == "0") 
     { 
      label.Text = "Number required"; 
     } 
     else 
     { 
      /*pager.PageSize = Convert.ToInt32(page_size_dropdown.SelectedValue);*/ 
      pager.PageSize = Convert.ToInt32(tb_page.Text); 
      label.Text = ""; 
     } 
    } 

    protected void Bearbeitung_Click(object sender, EventArgs e) 
    { 
     DataPager pager = ListView1.FindControl("DataPager1") as DataPager; 

     if (ListView1.Enabled == true) 
     { 
      ListView1.Enabled = false; 
      cmdUpdate.Enabled = false; 
      btn_Bearbeitung.Text = "Bearbeitung"; 
      cmdDelete.Enabled = false; 
      LinqDataSource1.DataBind(); 
      ListView1.DataBind(); 
     } 
     else 
     { 
      ListView1.Enabled = true; 
      cmdUpdate.Enabled = true; 
      cmdDelete.Enabled = true; 
      btn_Bearbeitung.Text = "Disable Editing"; 
     } 
    } 

我已經試過Datapager.Enabled =真正;和這種變化,但沒有成功。它似乎沒有啓用屬性。

找到了解決方案。我將Datapager從列表視圖中取出,並使用PagedControlID =「IdOfListView」。這意味着listview被禁用的事實不會影響數據讀寫器,因此它仍然可以完全正常工作。
