How to measure a canvas that has auto height and width
- by Wymmeroo
Hi Folks,
I'm a beginner in silverlight so i hope i can get an answer that brings me some more light in the measure process of silverlight.
I found an interessting flap out control from silverlight slide control
and now I try to use it in my project. So that the slide out is working proper, I have to place the user control on a canvas. The user control then uses for itself the height of its content. I just wanna change that behavior so that the height is set to the available space from the parent canvas.
You see the uxBorder where the height is set. How can I measure the actual height and set it to the border?
I tried it with Height={Binding ElementName=notificationCanvas, Path=ActualHeight} but this dependency property has no callback, so the actualHeight is never set.
What I want to achieve is a usercontrol like the tweetboard per example on Jesse Liberty's blog
Sorry for my English writing, I hope you understand my question.
<Canvas x:Name="notificationCanvas" Background="Red">
<SlideEffectEx:SimpleSlideControl GripWidth="20" GripTitle="Task" GripHeight="100">
<Border x:Name="uxBorder"
BorderThickness="2"
CornerRadius="5"
BorderBrush="DarkGray"
Background="DarkGray"
Padding="5" Width="300"
Height="700"

<StackPanel>
<TextBlock Text="Tasks"></TextBlock>
<Button x:Name="btn1" Margin="5" Content="{Binding ElementName=MainBorder, Path=Height}"></Button>
<Button x:Name="btn2" Margin="5" Content="Second Button"></Button>
<Button x:Name="btn3" Margin="5" Content="Third Button"></Button>
