ASP.NET（4.5）GridView分頁HTML標記缺失href鏈接

我在我的ASP.Net WebForms應用程序的一個頁面上有一個正確的工作asp:GridView，並且在另一個頁面上的一個非常類似的頁面不工作。問題在於分頁;我在asp:GridView控件上有AllowPaging=true，並在代碼隱藏中正確設置了OnPageIndexChanging="searchResultsGridView_PageIndexChanging"方法。運行時，分頁顯示正確（即使使用我在PagerStyle上的自定義css），但後續頁面的編號鏈接按鈕沒有在生成的標記中設置任何href=""。ASP.NET（4.5）GridView分頁HTML標記缺失href鏈接

這裏是生成的標記：

<tr align="center" class="gridViewPager"> 
     <td colspan="10"> 
      <table> 
       <tbody> 
       <tr> 
        <td> 
        <span>1</span> 
        </td> 
        <td> 
        <a>2</a> 
        </td> 
        <td> 
        <a>3</a> 
        </td> 
        <td> 
        <a>4</a> 
        </td> 
        <td> 
        <a>5</a> 
        </td> 
        <td> 
        <a>6</a> 
        </td> 
        <td> 
        <a>7</a> 
        </td> 
       </tr> 
       </tbody> 
      </table> 
     </td> 
</tr>

顯然，應該對<a>標籤的href=""屬性每個<td>但沒有。下面是來自具有正常工作分頁asp:GridView頁面的標記：

<td><a href="javascript:__doPostBack('ctl00$ModalPanelContentPlaceholder$designerSearchResultsGridView','Page$2')">2</a></td>

這裏是我的.aspx代碼：

<div id="searchResultsTableGridViewDivContainer" runat="server"> 
     <asp:GridView CssClass="table table-hover table-bordered" ID="searchResultsGridView" 
      AutoGenerateColumns="false" SelectedRowStyle-CssClass="info" 
      OnRowDataBound="searchResultsGridView_RowDataBound" 
      OnSelectedIndexChanged="searchResultsGridView_SelectedIndexChanged" AllowPaging="true" 
      PageSize="15" OnPageIndexChanging="searchResultsGridView_PageIndexChanging" 
      runat="server"> 
      <Columns> 
       <asp:BoundField HeaderText="Tracking #" DataField="TrackingNumber" /> 
       <asp:BoundField HeaderText="Product Type" DataField="ProductType.TypeName" /> 
       <asp:BoundField HeaderText="Design Type" DataField="DesignType.TypeName" /> 
       <asp:BoundField HeaderText="PWA #" DataField="PWAProductNumber" /> 
       <asp:BoundField HeaderText="PWB #" DataField="PWBProductNumber" /> 
       <asp:BoundField HeaderText="Rev" DataField="Revision" /> 
       <asp:BoundField HeaderText="Designers" DataField="DesignersCSV" /> 
       <asp:BoundField HeaderText="Status" DataField="Status.StatusName" /> 
       <asp:BoundField HeaderText="# Times Released" DataField="NumTimesReleased" /> 
       <asp:BoundField HeaderText="Queue Date" DataField="FormattedQueueDate" /> 
      </Columns> 
      <PagerStyle HorizontalAlign="Center" CssClass="gridViewPager" /> 
     </asp:GridView> 
    </div>

而且我的相關代碼隱藏：

/// <summary> 
    /// EVENT HANDLER: Handles the RowDataBound event of the customerSearchResultsGridView control. 
    /// 
    /// Allow the entire row to be clicked as a "Selector". 
    /// </summary> 
    /// <param name="sender">The source of the event.</param> 
    /// <param name="e">The <see cref="GridViewRowEventArgs"/> instance containing the event data.</param> 
    protected void searchResultsGridView_RowDataBound(object sender, GridViewRowEventArgs e) 
    { 
     if (e.Row.RowType == DataControlRowType.DataRow) 
     { 
      e.Row.Attributes["onclick"] = 
       ClientScript.GetPostBackClientHyperlink(searchResultsGridView, "Select$" + e.Row.RowIndex); 
     } 
    } 

    protected void searchResultsGridView_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     aboutProductBtnPanel.Enabled = (searchResultsGridView.SelectedRow == null) ? false : true; 
    } 

    /// <summary> 
    /// EVENT HANDLER: Handles the PageIndexChanging event of the searchResultsGridView control. 
    /// 
    /// Increment the next page of the GridView for results > 15. 
    /// </summary> 
    /// <param name="sender">The source of the event.</param> 
    /// <param name="e">The <see cref="GridViewPageEventArgs"/> instance containing the event data.</param> 
    protected void searchResultsGridView_PageIndexChanging(object sender, GridViewPageEventArgs e) 
    { 
     searchResultsGridView.PageIndex = e.NewPageIndex; 

     // don't refetch the data, just get it from the session 
     searchResultsGridView.DataSource = SessionWrapper.Current.CaptureProductSearchResults; 
     searchResultsGridView.DataBind(); 

     // new page, clear the selection 
     searchResultsGridView.SelectedIndex = -1; 
     aboutProductBtnPanel.Enabled = false; 
    }

任何想法爲什麼自動生成的HTML標記無法添加href鏈接？

只是爲了比較，你還可以發佈工作GridView的標記？ – Andrei

什麼是您的searchFormView對象？您對searchResultsGridView的所有其他引用都沒有此前綴。你可以嘗試刪除它在這一行：'searchFormView.SearchResultsGridView.DataBind（）;' – gotmilk13531

啊，@ gotmilk13531，因爲我的應用程序遵循MVP設計，所以我最初在外部演示者類中擁有searchResultsGridView_PageIndexChanging（）方法的內容模式。爲了簡化顯示的代碼，我將外部演示者的輔助方法的內容從代碼隱藏複製到事件方法中，但忘記擺脫演示者所看到的視圖的句柄。對於這個問題抱歉，但是searchFormView不應該，也不會涉及這個問題。我自更新了代碼以反映這一點。 – bradykey

事實證明，這個問題是一個雜交行，設置searchResultsGridView.Enabled = false;。因此，ASP.NET仍然會導致頁面的標記被渲染，但是爲了「禁用」asp:GridView，它只是巧妙地忽略了每個<a>標記的href=""。

小女孩，這是浪費了幾個小時。感謝您的時間，@ gotmilk13531和@Andrei。
