如何找到這些頁面的DetailsView抱選擇GridView的行

Question

我設立HealthMonitoring，我寫了幾頁來管理事件日誌。

我有一頁有GridView，另一頁有DetailsView。 GridView在每行上都有一個模板按鈕，並帶有一個onClick事件，該事件可加載第二頁，其上面有DetailsView。

我想要做的是;當我單擊GridView上的模板按鈕時，它將加載第二頁與DetailsView，並將GridView中的特定記錄插入到DetailsView表中。

DetailsView必須啓用分頁功能。我被卡住試圖找出哪個頁面索引加載GridView正確的記錄。目前它只會加載第一頁索引，然後點擊我需要的記錄旁邊。

如果沒有啓用分頁功能，我可以讀取我的2個全局變量，然後將正確的記錄加載到DetailsView表中，但啓用分頁功能後，我不知道如何去做。

在GridView頁：

protected void Details1_ButtonClick(object sender, EventArgs e) 
{ 
    //I set 2 global variables here of the selected EventId and 
    //Details to read when the next page loads 
    Response.Redirect("ErrorDetails.aspx"); 
} 

在DetailsView頁面。

protected void Page_Load(object sender, EventArgs e) 
{ 
    //without paging I can set the SqlDataSource1.SelectCommand to select 
    //the correct record using one of the global variables 
} 

我曾嘗試使用DetailsView1_PageIndexChanged，DetailsView1_Load和Page_Load獲得第一行中的值，但由於某些原因，它是永諾後面的頁面。變量總是顯示加載前一頁的ID。我將嘗試跟蹤刪除記錄的頁面，但它也不起作用。

這是ErrorDetails.aspx數據源和DetailsView：

<asp:SqlDataSource 
    ID="SqlDataSource1" 
    runat="server" 
    ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" 
    ProviderName="<%$ ConnectionStrings:DefaultConnection.ProviderName %>"> 
    <DeleteParameters> 
     <asp:Parameter Name="EventId" /> 
    </DeleteParameters> 
</asp:SqlDataSource> 

<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" DataSourceID="SqlDataSource1" DataKeyNames="EventId" AutoGenerateRows="False" OnItemDeleted="DetailsView1_ItemDeleted" OnItemDeleting="DetailsView1_ItemDeleting" AllowPaging="True" OnLoad="DetailsView1_Load" OnPageIndexChanged="DetailsView1_PageIndexChanged" OnPageIndexChanging="DetailsView1_PageIndexChanging"> 
    <AlternatingRowStyle CssClass="alt" /> 
    <Fields> 

     <asp:CommandField ShowDeleteButton="True" /> 

     <asp:BoundField DataField="EventId" HeaderText="EventId" /> 
     <asp:BoundField DataField="EventTimeUtc" HeaderText="EventTimeUtc" /> 
     <asp:BoundField DataField="EventTime" HeaderText="EventTime" /> 
     <asp:BoundField DataField="EventType" HeaderText="EventType" /> 
     <asp:BoundField DataField="EventSequence" HeaderText="EventSequence" /> 
     <asp:BoundField DataField="EventOccurrence" HeaderText="EventOccurrence" /> 
     <asp:BoundField DataField="EventCode" HeaderText="EventCode" /> 
     <asp:BoundField DataField="EventDetailCode" HeaderText="EventDetailCode" /> 
     <asp:BoundField DataField="Message" HeaderText="Message" /> 
     <asp:BoundField DataField="ApplicationPath" HeaderText="ApplicationPath" /> 
     <asp:BoundField DataField="ApplicationVirtualPath" HeaderText="ApplicationVirtualPath" /> 
     <asp:BoundField DataField="MachineName" HeaderText="MachineName" /> 
     <asp:BoundField DataField="RequestUrl" HeaderText="RequestUrl" /> 
     <asp:BoundField DataField="ExceptionType" HeaderText="ExceptionType" /> 

     <asp:TemplateField HeaderText="Details"> 
      <ItemTemplate> 
       <asp:Label ID="Label1" runat="server"> 
        <%= EventVariables.EventDetails %> 
       </asp:Label> 
      </ItemTemplate> 
     </asp:TemplateField> 

     <asp:CommandField ShowDeleteButton="True" /> 

    </Fields> 
    <PagerSettings Mode="NextPreviousFirstLast" /> 
    <PagerStyle CssClass="pager" /> 
</asp:DetailsView> 

這是DataSource和從母體形式GirdView：

<asp:GridView 
     ID="ErrorGrid" 
     runat="server" 
     AutoGenerateColumns="False" 
     DataSourceID="SqlDataSource1" 
     DataKeyNames="EventId" 
     OnRowDeleting="ErrorGrid_RowDeleting" 
     AllowPaging="True" 
     AllowSorting="True" 
     Font-Size="Small" 
     CellPadding="10" 
     CellSpacing="1" > 
     <Columns> 
      <asp:TemplateField ShowHeader="False"> 
       <ItemTemplate> 
        <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete"></asp:LinkButton> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:TemplateField ShowHeader="False"> 
       <ItemTemplate> 
        <asp:LinkButton ID="Details1" Text="Details" runat="server" AutoPostBack="true" OnClick="Details1_ButtonClick" /> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:BoundField DataField="EventId" HeaderText="EventId" SortExpression="EventId" /> 
      <asp:BoundField DataField="EventTime" HeaderText="EventTime" SortExpression="EventTime" /> 
      <asp:BoundField DataField="RequestUrl" HeaderText="RequestUrl" SortExpression="RequestUrl" /> 
      <asp:BoundField DataField="ExceptionType" HeaderText="ExceptionType" SortExpression="ExceptionType" /> 
     </Columns> 
    </asp:GridView> 
    <asp:SqlDataSource 
     ID="SqlDataSource1" 
     runat="server" 
     ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" 
     SelectCommand="SELECT * FROM [aspnet_WebEvent_Events]" 
     DeleteCommand="DELETE FROM [aspnet_WebEvent_Events] WHERE [EventId]=@EventId"> 
     <DeleteParameters> 
      <asp:Parameter Name="EventId" /> 
     </DeleteParameters> 
    </asp:SqlDataSource>

我管理通過執行計算，以解決這個問題。由於有，每頁10行的GridView我能夠通過這樣來計算的頁面：

EventVariables.EventPage = ((((ErrorGrid.PageIndex + 1) * 10) - 10) + Row.RowIndex); 

然後從變量加載在DetailsView頁面加載時。
