OnPageIndexChanging事件永遠不會在GridView上觸發

Question

我正在使用GridView控件並且分頁不起作用。在單步執行代碼時，當我單擊頁面時，將調用Page_Load事件，但我的OnPageIndexChanging事件從不會被調用。

<asp:GridView ID="FaxGrid" 
         runat="server"           
         BackColor="#FFFFFF" 
         HeaderStyle-BackColor="#CEDFF2" 
         HeaderStyle-ForeColor="#316495" 
         HeaderStyle-Font-Bold="true" 
         BorderColor="#CEDFF2" 
         AutoGenerateColumns="false" 
         OnRowCommand="FaxGridRowCommandHandler" 
         DataKeyNames="file_id" 
         AllowPaging="true" 
         PageSize="10" 
         PagerSettings-Mode="NumericFirstLast" 
         OnPageIndexChanging="FaxGrid_PageIndexChanging" 
         Height="222" 
         EmptyDataText="No faxes found." 
         HeaderStyle-Height="35" Width="1470" > 
          <Columns> 
           <asp:BoundField HeaderText="File Name" DataField="file_friendly_name" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:BoundField HeaderText="Dept. Name" DataField="department_name" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:BoundField HeaderText="Processed" DataField="processed" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="50"></asp:BoundField> 
           <asp:BoundField HeaderText="First Name" DataField="firstname" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:BoundField HeaderText="Last Name" DataField="lastname" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:BoundField HeaderText="DOB" DataField="dob" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="75"></asp:BoundField> 
           <asp:BoundField HeaderText="Ref. Physician" DataField="referringPhy" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:BoundField HeaderText="Reported" DataField="reported" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="75"></asp:BoundField> 
           <asp:BoundField HeaderText="Reported On" DataField="reportedon" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:BoundField HeaderText="Job Status" DataField="description" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="125"></asp:BoundField> 
           <asp:TemplateField HeaderText="Fax Options" HeaderStyle-Width="145"> 
            <ItemTemplate> 
             <asp:Button ID="btnCancel" runat="server" CommandName="CancelFax" CommandArgument='<%# Container.DataItemIndex %>' ToolTip="Cancel and delete fax" Text="Cancel" /> 
             <asp:Button ID="btnResend" runat="server" CommandName="Resend" CommandArgument='<%# Container.DataItemIndex %>' ToolTip="Resend an existing fax." Text="Resend" /> 
             <asp:Button ID="btnSendAsNew" runat="server" CommandName="SendAsNew" CommandArgument='<%# Container.DataItemIndex %>' ToolTip="Send as a new fax." Text="Send as New" /> 
            </ItemTemplate>     
           </asp:TemplateField> 
          </Columns> 
      </asp:GridView> 

這裏是隱藏文件我的代碼：

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (Page.IsPostBack == false) 
    { 
     this.sqlObj = new SqlServer(ConfigurationManager.ConnectionStrings["PdfReceiverConnectionString"].ToString()); 
     this.populateFaxGrid(); 
    } 
} 

protected void FaxGrid_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    this.FaxGrid.PageIndex = e.NewPageIndex; 

    this.FaxGrid.DataSource = this.Session["Faxes"]; 

    this.FaxGrid.DataBind(); 

} 

我明白任何幫助。

你的代碼看起來沒事，有時候複製粘貼代碼不會正確綁定事件，這發生在我身上不少時間。刪除該事件並重新綁定。
