ASP.net中的GridViews; C＃

我使用C＃和ASP.net創建gridviews ...我需要幫助創建2個gridviews，他們有相同的processID，並從同一個數據庫中的不同SQL表獲取數據。當我點擊第一行第一個gridview應該給我在第二個gridview中具有相同processID及其細節的文件列表ASP.net中的GridViews; C＃

一個進程ID有許多不同的xml文件存儲在其中例如processID = 7A413EA4-8ECE-472D-92BE- F58C22E5C567第一gridview的因此，所有的用戶名，日期，登錄其第二個表相同的ProcessID日的XML文件應該出現在第一表中選擇的行

這是我迄今所做的：

你可以做下列方式：

當您從網格線1在一行上點擊你應該觸發代碼隱藏文件的事件（看下面顯示的SelectedIndexChanged）。這裏面的事件，你應該查詢您的XML文件表發現，對電網1.選擇有了這樣一個查詢結果的行的相同的進程ID，你把它綁定到柵2

void LOG_GridView_SelectedIndexChanged(Object sender, EventArgs e) 
    { 
    // Get the currently selected row using the SelectedRow property. 
    GridViewRow row = CustomersGridView.SelectedRow; 

    // Do your logic here to query and databind to Grid 2... 
    }

寫的那些這在你的GRID1聲明：

<asp:GridView ID="LOG_GridView" runat="server" AllowPaging="True" AutoGenerateColumns="False" 
      CellPadding="4" DataSourceID="FS_PS2FS" ForeColor="#333333" Height="300px" Width="943px" HorizontalAlign="Center" CssClass="AlternatingRowStyle" PageSize="6" SelectedIndex="0" OnSelectedIndexChanging="LOG_GridView_SelectedIndexChanging" BorderColor="#999999" onselectedindexchanged="LOG_GridView_SelectedIndexChanged">

有關GridView控件的事件的更多信息，看看這些頁面在MSDN：

基本上你想要創建一個主/細節屏幕......這是作業嗎？無論如何，你想添加一個事件（選擇索引改變）到第一個網格。然後在那裏添加代碼，可以設置數據源或者「過濾」第二個網格中的數據，如果還沒有，也可以選擇使第二個網格可見。

第二個網格的數據源需要一個「WHERE」子句，它將比較數據源中的processID與第一個網格中選定的那個。您可以將第一個網格的數據鍵設置爲該字段（processID）以便於檢索。

祝你好運！

沒有它不是我的功課，我的工作，並就卡住不使用C＃.NET IM大多是用java – sweetsecret 2010-03-25 15:46:59

酷工作！這是更多的J/K :) – 2010-03-25 15:50:19

我真的需要幫助它...因爲我卡住了，無法弄清楚該怎麼做。這是一個主/細節grdview我wud說 – sweetsecret 2010-03-25 16:51:20

你應該能夠從標記中完成這一切。下面是使用Northwind數據庫

定義主GridView的工作示例：

<asp:GridView ID="master" runat="server" DataSourceID="sdsMaster" 
     AutoGenerateColumns="False" DataKeyNames="OrderID" AllowPaging="True" > 
    <Columns> 
     <asp:CommandField ShowSelectButton="True" /> 
     <asp:BoundField DataField="OrderID" HeaderText="OrderID" InsertVisible="False" 
      ReadOnly="True" SortExpression="OrderID" /> 
     <asp:BoundField DataField="CustomerID" HeaderText="CustomerID" 
      SortExpression="CustomerID" /> 
     <asp:BoundField DataField="EmployeeID" HeaderText="EmployeeID" 
      SortExpression="EmployeeID" /> 
     <asp:BoundField DataField="OrderDate" HeaderText="OrderDate" 
      SortExpression="OrderDate" /> 
     <asp:BoundField DataField="RequiredDate" HeaderText="RequiredDate" 
      SortExpression="RequiredDate" /> 
     <asp:BoundField DataField="ShippedDate" HeaderText="ShippedDate" 
      SortExpression="ShippedDate" /> 
     <asp:BoundField DataField="ShipVia" HeaderText="ShipVia" 
      SortExpression="ShipVia" /> 
     <asp:BoundField DataField="Freight" HeaderText="Freight" 
      SortExpression="Freight" /> 
    </Columns> 
    </asp:GridView>

定義細節GridView控件：

<asp:GridView ID="detail" runat="server" DataSourceID="sdsDetail" 
     AutoGenerateColumns="False" DataKeyNames="OrderID,ProductID" > 
    <Columns> 
     <asp:BoundField DataField="OrderID" HeaderText="OrderID" ReadOnly="True" 
      SortExpression="OrderID" /> 
     <asp:BoundField DataField="ProductID" HeaderText="ProductID" ReadOnly="True" 
      SortExpression="ProductID" /> 
     <asp:BoundField DataField="UnitPrice" HeaderText="UnitPrice" 
      SortExpression="UnitPrice" /> 
     <asp:BoundField DataField="Quantity" HeaderText="Quantity" 
      SortExpression="Quantity" /> 
     <asp:BoundField DataField="Discount" HeaderText="Discount" 
      SortExpression="Discount" /> 
    </Columns> 
    </asp:GridView>

這裏是主表中的SqlDataSource。只是基本的東西，選擇並顯示記錄：

<asp:SqlDataSource ID="sdsMaster" runat="server" 
     ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" 
     SelectCommand="SELECT [OrderID], [CustomerID], [EmployeeID], [OrderDate], [RequiredDate], [ShippedDate], [ShipVia], [Freight] FROM [Orders]" />

現在，在細節的SqlDataSource，使用where子句綁定到主GridView中選擇主鍵的SQL：

<asp:SqlDataSource ID="sdsDetail" runat="server" 
     ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" 
     SelectCommand="SELECT [OrderID], [ProductID], [UnitPrice], [Quantity], [Discount] FROM [Order Details] WHERE ([OrderID] = @OrderID)" > 
    <SelectParameters> 
     <asp:ControlParameter ControlID="master" DefaultValue="0" Name="OrderID" 
      PropertyName="SelectedValue" Type="Int32" /> 
    </SelectParameters> 
    </asp:SqlDataSource>

通知的SelectParameters和使用ControlParameter在主GridView中查找所選記錄的數據鍵。

編輯由於您正在使用您自己的數據庫與不同的字段名稱，然後相應地修改SQL。

FROM [FS_LOG_PS2FS_Validation] WHERE ([P2FV_ProcessId] = @LOG_ProcessId)

，改變SelectParameter

<SelectParameters> 
    <asp:ControlParameter ControlID="master" DefaultValue="0" Name="LOG_ProcessId" 
     PropertyName="SelectedValue" Type="Int32" /> 
</SelectParameters>

此外，您將需要設置的DataKeyNames在主GridView控件屬性

<asp:GridView ID="master" runat="server" DataSourceID="sdsMaster" 
      AutoGenerateColumns="False" DataKeyNames="LOG_ProcessID" AllowPaging="True" > 
     <Columns>

我不認爲你需要設置的DataKeyNames的細節GridView。爲了完整性，您也可以在那裏更改它。我在Visual Studio 2008設計視圖中使用智能標記來生成示例代碼。讓我知道如果這不明確。

在你的例子中，你有兩個表中的OrderID mycase我的意思是在第一個表中的問題processID被命名爲LOG_ProcessId，並在第二個表P2FV_ProcessId如何能這樣做 – sweetsecret 2010-03-25 17:37:02

我已經更新了我的答案。我希望這使事情更清楚。 – DaveB 2010-03-25 17:58:22
