先上张效果图看看 如果不如您的法眼 可以移步了 或者有更好的效果 可以留言给我
废话不多说 直接贴代码 一个usercontrol
<UserControl x:Class="LoadingMask_Demo.LoadingWait" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" IsVisibleChanged="HandleVisibleChanged"> <UserControl.Background> <SolidColorBrush Color="Black" Opacity="0.2" /> </UserControl.Background> <UserControl.Resources> <SolidColorBrush Color="#FF007BE5" x:Key="CirclesColor" /> <!--<SolidColorBrush Color="Black" x:Key="BackgroundColor" Opacity=".20" />--> </UserControl.Resources> <Viewbox Width="100" Height="100" HorizontalAlignment="Center" VerticalAlignment="Center"> <Grid x:Name="LayoutRoot" Background="Transparent" ToolTip="Please wait...."
