사용자 정의 컨트롤 내에서 GridView가 페이징하거나 정렬하지 않습니다.

Question

내 Gridview가 페이지를 정렬하거나 정렬하지 않습니다. 이것은 GridView의 데이터가 열별로 정렬하려고하거나 GridView를 통해 페이지하려고 할 때 변경되지 않는다는 것을 의미합니다.

사용자 정의 컨트롤 (.ascx)의 UpdatePanel 안에 있습니다. 아래 코드는 사용자 정의 컨트롤 외부에서 시도 할 때 잘 작동합니다.

<asp:GridView runat="server" ID="grdStats" AutoGenerateColumns="false" Width="100%" AllowSorting="true" 
     AllowPaging="true" PageSize="20" PagerSettings-Mode="NumericFirstLast" PagerSettings-Position="TopAndBottom"> 
     <Columns> 
      <asp:BoundField DataField="campaignname" HeaderText="Campaign Name" SortExpression="campaignname" /> 
      <asp:BoundField DataField="site_name" HeaderText="Outlet" SortExpression="site_name" /> 
      <asp:BoundField DataField="filename" HeaderText="Media" SortExpression="filename" /> 
      <asp:BoundField DataField="playinterval" HeaderText="Play Interval" SortExpression="playinterval" /> 
     </Columns> 
    </asp:GridView>

나는이 질문에 관련된 올바른 코드가 아니었지만, 그 질문에 붙여 넣은 코드에 대해 사과드립니다. 즉, 내 코드를 살펴볼 시간을내어 주신 것에 대해 감사드립니다. Icarus.

페이징/정렬이 작동합니다. 문제를 해결하기 위해 수행 한 작업은 PageIndexChanging 및 Sorting 이벤트 처리기 내의 GetCampaignData()에 대한 호출을 필요한 결과를 제공하는 데 필요한 SQL 코드 및 데이터 바인딩 메서드로 바꾸는 것이 었습니다.
