我需要在页面中显示主/子数据,我使用了多个 GridView 来实现相同的目的。因此,我创建了两个 GridView(父 subview ),现在我想从子 gridview 控件触发按钮单击事件(即 btnLock)并执行一些数据库操作。所以,我不知道如何实现这一目标。

请帮忙。

<asp:UpdatePanel ID="pnlUpdate" runat="server">
<ContentTemplate>
<asp:GridView Width="100%" AllowPaging="True" ID="gvCustomers" AutoGenerateColumns="False"
DataSourceID="sqlDsCustomers" runat="server" ShowHeader="False" OnRowCreated="gvCustomers_RowCreated">
<Columns>
<asp:TemplateField>
<ItemTemplate>

<div class="group" id='<%#String.Format("customer{0}",Container.DataItemIndex) %>' onclick='showhide(<%#String.Format("\"#customer{0}\"",Container.DataItemIndex) %>,<%#String.Format("\"#order{0}\"",Container.DataItemIndex) %>)'>
<asp:Image ID="imgCollapsible" CssClass="first" ImageUrl="~/Assets/img/plus.png"
Style="margin-right: 5px;" runat="server" /><span class="header">
<%#Eval("CustomerID")%>
:
<%#Eval("CompanyName")%>
(<%#Eval("TotalOrders")%>
Orders) </span>
</div>
<asp:SqlDataSource ID="sqlDsOrders" runat="server" ConnectionString="<%$ ConnectionStrings:Northwind %>"
SelectCommand="SELECT [OrderID], [OrderDate], [RequiredDate], [Freight], [ShippedDate] FROM [Orders] WHERE ([CustomerID] = @CustomerID)">
<SelectParameters>
<asp:Parameter Name="CustomerID" Type="String" DefaultValue="" />
</SelectParameters>
</asp:SqlDataSource>
<div id='<%#String.Format("order{0}",Container.DataItemIndex) %>' class="order">
<asp:GridView AutoGenerateColumns="false" CssClass="grid" ID="gvOrders" DataSourceID="sqlDsOrders"
runat="server" ShowHeader="true" EnableViewState="false">
<RowStyle CssClass="row" />
<AlternatingRowStyle CssClass="altrow" />
<Columns>
<asp:TemplateField ItemStyle-CssClass="rownum">
<ItemTemplate>
<%# Container.DataItemIndex + 1 %>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="Order ID" DataField="OrderID" ItemStyle-Width="80px" />
<asp:BoundField HeaderText="Date Ordered" DataField="OrderDate" DataFormatString="{0:MM/dd/yyyy}"
ItemStyle-Width="100px" />
<asp:BoundField HeaderText="Date Required" DataField="RequiredDate" DataFormatString="{0:MM/dd/yyyy}"
ItemStyle-Width="110px" />
<asp:BoundField HeaderText="Freight" DataField="Freight" DataFormatString="{0:c}"
ItemStyle-Width="50px" ItemStyle-HorizontalAlign="Right" />
<asp:BoundField HeaderText="Date Shipped" DataField="ShippedDate" DataFormatString="{0:MM/dd/yyyy}"
ItemStyle-Width="100px" />
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="btnLock" Text="Lock" CommandName="Lock" CommandArgument=<%# Eval("OrderID") %> runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>

谢谢

最佳答案

使用行命令:

 <asp:GridView AutoGenerateColumns="false" CssClass="grid" ID="gvOrders" DataSourceID="sqlDsOrders"
runat="server" ShowHeader="true" EnableViewState="false"
onrowcommand="gvOrders_RowCommand"
>
........
</asp:GridView >


protected void gvOrders_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="Lock")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
//dowork

}
}
