HoverMenu控件

HoverMenu控件的功能是实现鼠标移过显示一个自定义的菜单，把一个控件作为一个目标的菜单显示。如Panel控件。

属性列表：
TargetControlID： 显示的Plane的ID
HoverCssClass： 显示的Plane的CSS
PopupPostion： 悬浮的位置：Left (默认), Right, Top, Bottom, Center
OffsetX/OffsetY： 相对于默认值的偏移值
PopDelay ：出现Plane的延时，默认是100.
Animations ：参照前面动画控件Animations

实例解析一、当移动到文本框上显示菜单，选择其中一项文本框获得相应值

1.UI界面：
<form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>   
    </div>
        <asp:Panel ID="Panel1" runat="server" Height="50px" Width="125px">
            <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">LinkButton1</asp:LinkButton><br />
            <asp:LinkButton ID="LinkButton2" runat="server" OnClick="LinkButton2_Click">LinkButton2</asp:LinkButton><br />
            <asp:LinkButton ID="LinkButton3" runat="server" OnClick="LinkButton3_Click">LinkButton3</asp:LinkButton></asp:Panel>
        <cc1:hovermenuextender id="HoverMenuExtender1" runat="server" offsetx="-1" offsety="-1"
            popupcontrolid="Panel1" popupposition="Bottom" targetcontrolid="TextBox1"></cc1:hovermenuextender>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </form>
2.后台：
    protected void LinkButton1_Click(object sender, EventArgs e)
    {
        TextBox1.Text = LinkButton1.Text.ToString();
    }
    protected void LinkButton2_Click(object sender, EventArgs e)
    {
        TextBox1.Text = LinkButton2.Text.ToString();
    }
    protected void LinkButton3_Click(object sender, EventArgs e)
    {
        TextBox1.Text = LinkButton3.Text.ToString();
    }

实例解析二、使用此控件实现GridView的编辑和删除

注意：
四个按钮的CommandArgument="Update" CommandName="Update"必须准备的写
SqlDataSource数据源必须指弄索引主键并启用INSERT,UPDATE,DELETE功能

 <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" Width="623px">
            <Columns>
                <asp:TemplateField HeaderText="UserName" SortExpression="UserName">
                    <EditItemTemplate>
                   
<asp:Panel ID="PanelUpdate" runat="server" Height="50px" Width="125px">
            <asp:LinkButton ID="LinkButtonUpdata" runat="server" CommandArgument="Update" CommandName="Update">更新/asp:LinkButton>
            <br />
            <asp:LinkButton ID="LinkButtonChanel" runat="server" CommandArgument="Cacel" CommandName="Cancel">取消</asp:LinkButton>                     </asp:Panel>
                   
                        <asp:Panel ID="PanelEdit" runat="server" Height="50px" Width="125px">
                        <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("UserName") %>'></asp:TextBox>
                        </asp:Panel>
                       
                        <cc1:HoverMenuExtender ID="HoverMenuExtender2" runat="server" OffsetX="1" OffsetY="-1" TargetControlID="PanelEdit" PopupControlID="PanelUpdate" PopupPosition="Left">
                        </cc1:HoverMenuExtender>
                       
                    </EditItemTemplate>
                    <ItemTemplate>
                   
<asp:Panel ID="PanelDel" runat="server" Height="50px" Width="125px">
            <asp:LinkButton ID="LinkButtonDel" runat="server" CommandArgument="Delete" CommandName="Delete">删除</asp:LinkButton>
            <br />
            <asp:LinkButton ID="LinkButtonEdit" runat="server" CommandArgument="Edit" CommandName="Edit">编辑</asp:LinkButton></asp:Panel>
                   
                        <asp:Panel ID="PanelContent" runat="server" Height="50px" Width="125px">
                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("UserName") %>'></asp:Label>
                        </asp:Panel>    
                       
                        <cc1:HoverMenuExtender ID="HoverMenuExtender3" runat="server" OffsetX="1" OffsetY="-1" TargetControlID="PanelContent" PopupControlID="PanelDel" PopupPosition="Left">
                        </cc1:HoverMenuExtender>  
                                               
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:db_04ConnectionString %>"
            DeleteCommand="DELETE FROM [tb_Employee] WHERE [UserID] = @UserID" InsertCommand="INSERT INTO [tb_Employee] ([UserName]) VALUES (@UserName)"
            SelectCommand="SELECT [UserID], [UserName] FROM [tb_Employee]"
            UpdateCommand="UPDATE [tb_Employee] SET [UserName] = @UserName WHERE [UserID] = @UserID">
            <DeleteParameters>
                <asp:Parameter Name="UserID" Type="Int64" />
            </DeleteParameters>
            <UpdateParameters>
                <asp:Parameter Name="UserName" Type="String" />
                <asp:Parameter Name="UserID" Type="Int64" />
            </UpdateParameters>
            <InsertParameters>
                <asp:Parameter Name="UserName" Type="String" />
            </InsertParameters>
        </asp:SqlDataSource>
