消息框的 Silverlight BusyIndicator 背景颜色 [英] Silverlight BusyIndicator background color for the message box
问题描述
在 Silverlight 中,我需要 BusyIndicator 的消息框是透明的.我发现了一个问题,但没有任何解决方案:
In Silverlight, I need the message box of a BusyIndicator to be transparent. I found a question asking the same but without any solution:
Silverlight BusyIndicator 背景色
我的部分代码如下:
<toolkit:BusyIndicator x:Name="WorkingLayout" Height="80">
<toolkit:BusyIndicator.BusyContent>
<StackPanel>
<TextBlock Text="Wait please..." HorizontalAlignment="Center"></TextBlock>
<Button x:Name="CancelButton" HorizontalAlignment="Center" Content="Cancel" Width="100" Click="CancelButton_Click" />
</StackPanel>
</toolkit:BusyIndicator.BusyContent>
<!-- Rest of component code -->
</toolkit:BusyIndicator>
有没有办法让所有内容背景都透明,包括包含消息的框,而不是默认的灰色渐变?
Is there a way to make all the content background transparent, including the box containing the message, not in grey gradient as it comes as default?
我尝试将属性背景设置为透明:
I tried to set the property Background to transparent like that:
<toolkit:BusyIndicator x:Name="WorkingLayout" Height="80" Background="Transparent">
但是没有用.
推荐答案
你可以得到你想要的,你只需要编辑模板来满足你的需要.在表情混合中,
You can get what you want, you just have to edit the template to suit your needs. In expression blend,
- 右键单击忙指示符,选择编辑模板,编辑副本
- 在模板里面,找到进度条,删除
如果要删除灰色框,请将内容演示器向上移动到更高的网格,并删除边框对象这是我制作的一个忙碌指标示例,
- Right click the busy indicator, select edit template, edit a copy
- Inside the template, find the progress bar, and delete it
If you want to remove the gray box, move the Content presenter up to a higher grid, and delete the border objects here is one sample busyindicator i made,
