錯誤：「容量小於當前大小」與ASP.NET DataPager控件

Question

我有一個ASP.NET的ListView與DataPager的按本代碼：

 <asp:ListView ID="TicketsPerPersonListView" runat="server" DataSourceID="ObjectDataSource1"> 
     <EmptyDataTemplate> 
      -- No Records Found -- 
     </EmptyDataTemplate> 
     <ItemTemplate> 
      <tr style="display: table-row;"> 
       <td> 
        <a href="viewticket.aspx?id=<%#Eval("ticket_id")%>">#<%# Eval("TicketID")%>- 
         <%# Eval("ShortDesc")%></a> 
       </td> 
       <td> 
        <%# Eval("StatusName")%> 
       </td> 
       <td style="text-align: right; padding-right: 60px;"> 
        <%# Eval("StatusDescription")%> 
       </td> 
       <td style="text-align: right; padding-right: 60px;"> 
        <%# Eval("TimeLastAction")%> 
       </td> 
      </tr> 
     </ItemTemplate> 
     <LayoutTemplate> 
      <table> 
       <thead> 
        <tr> 
         <th> 
          Title 
         </th> 
         <th style="text-align: right; padding-right: 60px;"> 
          Current Status 
         </th> 
         <th style="text-align: right; padding-right: 60px;"> 
          Latest Action 
         </th> 
         <th style="text-align: right; padding-right: 60px;"> 
          Last Viewed 
         </th> 
        </tr> 
       </thead> 
       <tfoot> 
        <tr> 
         <td colspan="5"> 
          <div class="pagination">

              ShowPreviousPageButton="False" /> 
            </Fields> 
           </asp:DataPager> 
          </div> 
         </td> 
        </tr> 
       </tfoot> 
       <tbody> 
        <asp:PlaceHolder runat="server" ID="itemPlaceholder"></asp:PlaceHolder> 
        <tr style="display: table-row;"> 
        </tr> 
       </tbody> 
      </table> 
     </LayoutTemplate> 
    </asp:ListView> 
    <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" EnablePaging="True" SelectMethod="FindByUserID" 
     TypeName="Xyratex.XCS.Services.TicketService" StartRowIndexParameterName="startRowIndex" 
     MaximumRowsParameterName="maximumRows" SelectCountMethod="CountByUserID"> 
     <SelectParameters> 
      <asp:Parameter Name="userID" DbType="Int64" DefaultValue="79" /> 
      <asp:ControlParameter Name="custID" ControlID="DDCaller" ConvertEmptyStringToNull="True" 
       DefaultValue="" /> 
      <asp:ControlParameter Name="company" ControlID="DDCompany" ConvertEmptyStringToNull="True" 
       DefaultValue="" /> 
      <asp:ControlParameter Name="owner" ControlID="DDOwner" ConvertEmptyStringToNull="True" 
       DefaultValue="" /> 
      <asp:ControlParameter Name="action" ControlID="DDAction" ConvertEmptyStringToNull="True" 
       DefaultValue="" /> 
      <asp:ControlParameter Name="status" ControlID="DDCurrentStatus" ConvertEmptyStringToNull="True" 
       DefaultValue="" /> 
     </SelectParameters> 
    </asp:ObjectDataSource> 

的VB.NET代碼提供了與數據將ObjectDataSource因此：

''' <summary> 
''' Finds all the <see cref="Xyratex.XCS.Model.Tickets.Ticket" /> objects belonging to the specified user ID 
''' </summary> 
''' <param name="userID">The id of the user to find tickets for</param> 
''' <param name="startRowIndex">The starting index of the portion of the recordset</param> 
''' <param name="maximumRows">The maximum amount of rows to return</param> 
''' <param name="custID">The id of the customer to find tickets for</param> 
''' <param name="company">The company name to find tickets for</param> 
''' <param name="owner">The owner to find tickets for</param> 
''' <param name="action">The action to find tickets for</param> 
''' <param name="status">The status of tickets to find.</param> 
''' <returns>A <see cref="System.Collections.Generic.IList(Of Xyratex.XCS.Model.Tickets.Ticket)" /> object</returns>

當我加載頁面時，收到錯誤「容量小於當前大小」。堆棧跟蹤是每從而：

是否一個你知道該怎麼辦？

Answer 1

我解決它！

計數方法返回一個System.Int64。當這被修改爲System.Int32時，它就起作用了！
