ajaxToolkit:ModalPopupExtender演示与应用

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：http://www.cnblogs.com/insus/archive/2011/09/07/2169742.html

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"：

View Code                                     class="lazyload" src="https://www.mshxw.com/file/upload/202104/26/215253990.png" data-original="../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。

View Code                                  border-width: 3px; border-style: solid; border-color: Gray; padding: 3px; width: 500px;">
                                                                    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
                                
                                                                    border: solid 1px Gray; color: Black; height: 20px; text-align: center; line-height: 20px;">
                                                                            onClientClick="return false;" Text="×" ForeColor="Red" ToolTip="Close" />
                                
                                
                                                                            BorderStyle="Solid" BorderWidth="1px" BorderColor="Gray">
                                        
                                            
                                        
                                    
                                    
                                    
                                    
                                                                                    CausesValidation="false" CssClass="button" />
                                    
                                
                            
                                                            PopupControlID="pnlPopupWindown" BackgroundCssClass="modalBackground" CancelControlID="btnClose"
                                DropShadow="true" PopupDragHandleControlID="Panel3" />
                            

最后是CSS样式：

View Code
.modalBackground
{
    background-color: Gray;
    filter: alpha(opacity=70);
    opacity: 0.7;
}
