ajaxToolkit:ModalPopupExtender可以让用户模拟新开一个窗口,以下演示,就是在模拟新开窗口作多项选项的功能。 演示例子中,是Repeater结合CheckBox进行多选,此功能实现,可以参考:https://www.ogeek.net/article/33558.htm 选择的小图片,它将要被ajaxToolkit:ModalPopupExtender使用,因为需要设为服务控件,添加runat="server": 复制代码 代码如下: <img id="ab" runat="server" style="margin-left: 5px; margin-bottom: 30px;" src="../Image/ab.gif" width="18" height="18" /> 下面是Popup窗口的Html,不过Insus.NET已经省略了Repeater控件内的内容,你在应用时,需要添加的你自己的,还是就是btnSelected_Click事件。 复制代码 代码如下: <asp:Panel ID="pnlPopupWindown" runat="server" Style="display: none; background-color: #ffffdd; border-width: 3px; border-style: solid; border-color: Gray; padding: 3px; width: 500px;"> <asp:Panel ID="Panel3" runat="server" Style="float: left; margin-bottom: 5px; cursor: move; background-color: #DDDDDD; border: solid 1px Gray; color: Black; height: 20px; width: 475px; text-align: center; line-height: 20px;"> 邮件地址列表 </asp:Panel> <asp:Panel ID="Panel4" runat="server" Style="float: right; margin-bottom: 5px; background-color: #DDDDDD; border: solid 1px Gray; color: Black; height: 20px; text-align: center; line-height: 20px;"> <asp:LinkButton ID="btnClose" runat="server" Style="margin-right: 4px; margin-left: 4px;" OnClientClick="return false;" Text="×" ForeColor="Red" ToolTip="Close" /> </asp:Panel> <div> <asp:Panel ID="Panel1" runat="server" ScrollBars="Vertical" Height="198px" Width="100%" BorderStyle="Solid" BorderWidth="1px" BorderColor="Gray"> <asp:Repeater ID="RepeaterEmailList" runat="server"> </asp:Repeater> </asp:Panel> <div style="height: 3px;"> </div> <asp:Panel ID="Panel2" runat="server"> <asp:Button ID="btnSelected" runat="server" OnClick="btnSelected_Click" Text="插入" CausesValidation="false" CssClass="button" /> </asp:Panel> </div> </asp:Panel> <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="ab" PopupControlID="pnlPopupWindown" BackgroundCssClass="modalBackground" CancelControlID="btnClose" DropShadow="true" PopupDragHandleControlID="Panel3" /> <script type="text/javascript"> function setBodyHeightToContentHeight() { document.body.style.height = Math.max(document.documentElement.scrollHeight, document.body.scrollHeight) + "px"; } setBodyHeightToContentHeight(); $addHandler(window, "resize", setBodyHeightToContentHeight); </script> 最后是CSS样式: 复制代码 代码如下: /*Modal Popup*/ .modalBackground { background-color: Gray; filter: alpha(opacity=70); opacity: 0.7; } |
