使用GridView的Ajax控件Toolkit Hover菜单

Question

您好我在http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/HoverMenu/HoverMenu.aspx

尝试实现示例悬停菜单的相同功能

然而，当我的网格视图显示和我鼠标悬停在菜单上时，但仅针对整个网格视图而不是像示例中的每一行？目前菜单按钮什么都不做。

    <asp:UpdatePanel ID="up1" runat="server">
        <ContentTemplate>

            <asp:GridView ID="GridView1" runat="server"
                AutoGenerateColumns="False" DataSourceID="BookingsSQL"
                ShowHeader="False" Width="100%" BackColor="Azure" GridLines="None" >
                <Columns>
                    <asp:BoundField DataField="programme_name" HeaderText="programme_name" 
                        SortExpression="programme_name" />
                    <asp:BoundField DataField="Start" HeaderText="Start" SortExpression="Start" />
                    <asp:BoundField DataField="Finish" HeaderText="Finish" 
                        SortExpression="Finish" />
                    <asp:BoundField DataField="Source" HeaderText="Source" 
                        SortExpression="Source" />
                    <asp:BoundField DataField="Destination" HeaderText="Destination" 
                        SortExpression="Destination" />
                    <asp:BoundField DataField="Comment" HeaderText="Comment" 
                        SortExpression="Comment" />
                </Columns>
            </asp:GridView>
            <asp:SqlDataSource ID="BookingsSQL" runat="server"
                ConnectionString="<%$ ConnectionStrings:BookingsConnectionString %>" 
                SelectCommand="SELECT [programme name] AS programme_name, [Start], [Finish], [Source], [Destination], [Comment] FROM [Bookings]">

            </asp:SqlDataSource>

            <asp:HoverMenuExtender ID="HoverMenuExtender1" runat="server"
             TargetControlID="GridView1"
                PopupControlID="PopupMenu"
                HoverCssClass="popupHover"
                PopupPosition="Left"
                OffsetX="0"
                OffsetY="0"
                PopDelay="50">
            </asp:HoverMenuExtender>
           <asp:Panel CssClass="popupMenu" ID="PopupMenu"  runat="server">
                <asp:LinkButton ID="LinkButton1" runat="server" CommandName="Edit" Text="Edit" />
                <br />
                <asp:LinkButton ID="LinkButton2" runat="server" 
                 CommandName="Delete" Text="Delete" />
            </asp:Panel>

        </ContentTemplate>

    </asp:UpdatePanel>

使用jquery悬停尝试了几种不同的方法，但这将是最好的解决方案。 请帮忙。谢谢。

有解决方案。 为示例工具包示例中显示的每行实现HoverExtender并不是那么棘手，因为它提供了带有排序的列标题。

请注意，在预订表中添加了代理主键，允许编辑所有字段值。此外，还使用jQuery datepicker插件来编辑“开始”和“完成”字段值。您可以使用AjaxControlToolkit中的DatePickerExtender，但在这种情况下，必须为网格中的每一行添加这些扩展程序以及HoverExtender。

感谢您提供了如此大的帮助......它为我工作我使用了SqlDataSource而不是使用objectDataSource ... 这是我正在运行的代码，对我来说非常有用....

<asp:UpdatePanel ID="up1" runat="server">
    <ContentTemplate>

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
 ShowHeader="False" Width="100%" BackColor="Azure" GridLines="None" DataKeyNames="PageAddID">

           <ItemTemplate>
                <table id="Table1" runat="server" visible="<%# Container.DataItemIndex == 0 %>">
                     <tr>
