silverlight - Silverlight BusyIndicator 的 Ajax 样式？

Question

我正在寻找一个示例样式，以将 Silverlight BusyIndicator 的外观更改为更像 AJAX 应用程序的“旋转轮”外观。

绕谷歌一圈会产生一些链接，这些链接指向人们正在创建新控件以实现相同目的的位置（我怀疑他们早于 BusyIndicator），但如果可能的话，我宁愿剥去 BusyIndicator 的皮肤。

有人给我正确的方向吗？

谢谢

我使用BusyIndicatorSilverlight Toolkit进行了自定义

这是您需要的：

在样式文件中设置 System 命名空间：

xmlns:System="clr-命名空间:System;assembly=mscorlib"

将样式/模板放入您的样式文件中：

<ControlTemplate x:Key="AjaxBusyIndicatorControlTemplate" TargetType="toolkit:BusyIndicator">
    <Grid x:Name="ColorLayer">               
        <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="VisibilityStates">
                <VisualState x:Name="Hidden">

<Style x:Key="AjaxBusyIndicator" TargetType="toolkit:BusyIndicator"  >
    <Setter Property="Template" Value="{StaticResource AjaxBusyIndicatorControlTemplate}"/>
</Style>

在您的 XAML 中使用它：

<Grid x:Name="LayoutRoot" Background="White">
    <toolkit:BusyIndicator IsBusy="True" Style="{StaticResource AjaxBusyIndicator}">
        <TextBox Text="TEST test test" />
    </toolkit:BusyIndicator>
</Grid>

嗯，真的是一个常见的场景。 Silverlight 开发人员通常使用 http://blogs.msdn.com/b/brada/archive/2009/03/20/silverlight-3-activity-control.aspx这种类型的控件。但由于您的要求是像 AJAX 一样拥有它，我认为此链接可能会有所帮助： http ://chrisa.wordpress.com/2008/10/09/a-wait-indicator-in-silverlight/
