asp.net - Ajax 控件工具包 Hover Menu with GridView

Question

您好，我正在尝试实现与 http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/HoverMenu/HoverMenu.aspx 上的示例悬停菜单相同的功能。

但是，当我的 GridView 显示并且我将鼠标悬停在菜单上时，菜单会出现，但仅针对整个 GridView ，而不是像示例中那样的每一行？目前菜单按钮没有任何作用。

    <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。 请提供任何帮助。谢谢。

有解决办法。 为每一行实现 HoverExtender 并不那么棘手，因为这在示例工具包示例中显示，为提供带有排序的列标题。

请注意，预订表中添加了代理主键，以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单独添加这些扩展程序以及 HoverExtender。
