How to add border around canvas element? Border should be same size as canvas.
I am using below code for this, but couldn't able to achieve the result.
<Canvas Background="Transparent" Margin="69,-30,56,315" x:Name="LetterCanvas" >
<Border x:Name="CanvasBorder" BorderThickness="5" Height="271" Width="325">
</Border></Canvas>
You need to place the Border outside of the Canvas:
<Border>
<Canvas>
</Canvas>
</Border>

I'm trying to place a Border around a StackPanel like so:
<Border CornerRadius="5" BorderBrush="#009999" Background="Transparent"
BorderThickness="2" Grid.Column="2" Grid.Row="0">
<StackPanel HorizontalAlignment="Center" Margin="0,30,0,0">
<!--Contents-->
</StackPanel>
</Border>
For some reason, the border is appearing around the column that the StackPanel is in, not the StackPanel itself. I can change the margin of the border, but that doesn't hold up if the screen is resized. I also tried getting rid of the StackPanel margin but that made no difference. The StackPanel is the only object in this column.
Border has default HorizontalAlignment equal to Stretch, so it takes full possible width.
Then StackPanel is centered inside the border because it has HorizontalAlignment="Center".
set HorizontalAlignment="Center" on Border. It will get width, equal to StackPanel width (plus Margin), and then will be centered
I think it is because you're setting the HorizontalAlignment to Center. Doing this will make the StackPanel size to whatever its content is.
If you move the Border to stackpanel your problems will be fixed :)
here it is:
<Grid>
<StackPanel Width="350" Height="200">
<Border BorderThickness="2" BorderBrush="Black" Width="350" Height="200">
<TextBlock>SomeText</TextBlock>
</Border>
</StackPanel>
</Grid>
I implemented the canvas from the code project example Drag controls in canvas
Here user has the ability to move anywhere in the canvas, when control reaches top or bottom, i want to show the vertical scrollbar. How can I make this work?
<ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Visible">
<Grid Name="grid">
<Canvas Name="canvastoExport" >
<Polygon Points="200,100,300,100,300,200,200,200" Fill="Green"></Polygon>
</Canvas>
</Grid>
</ScrollViewer>
I have a more StackPanels in my XAML. Every StackPanel has a border inside.
When I modify the Main Window the width follows the resizing. But the height follows only in one the bigger direction. If I make the Window smaller the height of the borders doesn't follows. So the effect is the Botton border line isn't visible. How can I do this ?
<Window x:Class="MyStackPanel"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MyCombobox" Height="356" Width="475">
<Grid>
<StackPanel x:Name="STP"
Margin="10">
<Border x:Name="STPB"
BorderBrush="#FFE80707"
BorderThickness="5"
CornerRadius="10"
Height="{Binding ElementName=STP,Path=ActualHeight}"/>
</StackPanel>
</Grid>
</Window>
!border normaly Looks like
Use a Grid instead of a StackPanel then the border will stretch to the
Grids height and width on resizing
<Grid x:Name="STP"
Margin="10">
<Border x:Name="STPB"
BorderBrush="#FFE80707"
BorderThickness="5"
CornerRadius="10" />
</Grid>
Window after your changes, Looks like the same after reize (make smaller) without your changes.

I want my to have a sunken border like a textbox. How to do this? Is there a way to get the controltemplate to mimc the parent border?
There is no theme for you to use, but you can work around like this:
Using this MSDN model (http://i.msdn.microsoft.com/dynimg/IC84967.gif):
Here's my recommendation: (sunken inner)
Just change the height/width of the outside border and you use this block of XAML like a TextBox. Reverse the two border tags if you want an outder border instead. Should be easy for you.
<Border Width="100" Height="200"
BorderBrush="Gainsboro" BorderThickness="0,0,5,5">
<Border BorderBrush="Gray" BorderThickness="5,5,0,0">
<TextBox Text="Hello World"
BorderThickness="0"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch" />
</Border>
</Border>
Special thanks to: Style a border with a different brush color for each corner
Should look like this:
You can try something like this
<Border Margin="20" BorderThickness="0.5" BorderBrush="Gray">
<Border BorderThickness="1,1,0,0" BorderBrush="DarkGray">
<ContentPresenter />
</Border>
</Border>
You might need to play with the colours though.
Canvas doesn't seem to play well together nicely with the other elements when you try to build it into a layout and have e.g. controls on the side and the canvas is the drawing area.
For instance, why can I put a border around every element except a canvas? In the following code, border wraps canvas but the canvas only has the border on the top but not on the left, right or bottom:
<Window x:Class="WpfApplication25.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<StackPanel>
<TextBlock DockPanel.Dock="Bottom" Text="Move the slider to reveal the answer:"/>
<Slider DockPanel.Dock="Bottom" Name="theSlider"
HorizontalAlignment="Left"
Width="200"
Minimum="0"
Maximum="1"
Value="1"
Cursor="Hand"/>
<Border BorderBrush="Tan" BorderThickness="2">
<Canvas>
<TextBlock Canvas.Left="45" Canvas.Top="50" Text="test" FontSize="16"/>
<Rectangle
Canvas.Left="10"
Canvas.Top="10"
Width="100"
Height="100"
Fill="Silver"
Opacity="{Binding ElementName=theSlider, Path=Value}"
/>
</Canvas>
</Border>
</StackPanel>
</Window>
From what I can tell in XamlPad, the problem appears to be that your Canvas does not have an explicit height/width, and that its HorizontalAlignment defaults to being in the middle of the Border. Without an explicit height and width the Border appears to collapse to 0 height and stretches on the width. My assumption is this is because your Border is in a StackPanel, as placing the Border in a Grid, causes it to behave as expected.
Your best bet is to give the Canvas an explicit Height and Width. Not sure that is what you're looking for though.
As far as I understand what you are trying to achieve, you should place your controls in one cell of a Grid and your Canvas in another.
