In WPF, i wish to create rounded corner for my movie, but the movie actually will overlap the border and i get a normal rectangle box that load my movie. Any idea how to solve this issue?
<Border BorderBrush="#FF000000" BorderThickness="1,1,1,1" CornerRadius="20,20,20,20">
<Grid>
<MediaElement x:Name="movieLoader" HorizontalAlignment="Left" Height="128" VerticalAlignment="Top" Width="236" Source="../video/empty.mp4"/>
</Grid>
</Border>
Try this:
<Border x:Name="border" BorderThickness="1" BorderBrush="#FF000000" CornerRadius="20" Padding="1"
HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid>
<Border Name="mask" Background="White" CornerRadius="{Binding ElementName=border, Path=CornerRadius}"/>
<Grid>
<Grid.OpacityMask>
<VisualBrush Visual="{Binding ElementName=mask}"/>
</Grid.OpacityMask>
<MediaElement x:Name="movieLoader" HorizontalAlignment="Left" Height="128"
VerticalAlignment="Top" Width="236" Source="../video/empty.mp4"/>
</Grid>
</Grid>
</Border>
Set ClipToBounds to True.
<Border ClipToBounds="True" BorderBrush="#FF000000" BorderThickness="1"
CornerRadius="20">
<Grid>
<MediaElement x:Name="movieLoader" HorizontalAlignment="Left"
Height="128" VerticalAlignment="Top" Width="236"
Source="../video/empty.mp4"/>
</Grid>
</Border>

How to get these dockpanels right ?
<DockPanel Grid.Row="1" LastChildFill="True" HorizontalAlignment="Stretch">
<DockPanel Width="400" LastChildFill="False" HorizontalAlignment="Left">
<DockPanel>
<TextBlock Width="400" />
</DockPanel>
<DockPanel Height="35" DockPanel.Dock="Bottom" LastChildFill="False">
<Button x:Name="btnRefresh" Content="Refersh" />
</DockPanel>
</DockPanel>
The DockPanel with the TextBlock spans over the DockPanel that is docked at the bottom, I want it to fit right up to it. Any ideas?
Ok, it turns out: the panel docked at the bottom must preceed the dockpanel above it in the xaml declaration. LastChildFill="True" applies to the control that is declared last in the code.
<DockPanel Grid.Row="1" LastChildFill="True" HorizontalAlignment="Stretch">
<DockPanel Width="400" LastChildFill="False" HorizontalAlignment="Left">
<DockPanel Height="35" DockPanel.Dock="Bottom" LastChildFill="False">
<Button x:Name="btnRefresh" Content="Refersh" />
</DockPanel>
<DockPanel>
<TextBlock Width="400" />
</DockPanel>
</DockPanel>
Please refer to the DockPanel Class page at MSDN which has all the help that you need. The XAML example from the linked page:
<DockPanel LastChildFill="True">
<Border Height="25" Background="SkyBlue" BorderBrush="Black" BorderThickness="1"
DockPanel.Dock="Top">
<TextBlock Foreground="Black">Dock = "Top"</TextBlock>
</Border>
<Border Height="25" Background="Blue" BorderBrush="Black" BorderThickness="1"
DockPanel.Dock="Top">
<TextBlock Foreground="White">Dock = "Top"</TextBlock>
</Border>
<Border Height="25" Background="Yellow" BorderBrush="Black" BorderThickness="1"
DockPanel.Dock="Bottom">
<TextBlock Foreground="Black">Dock = "Bottom"</TextBlock>
</Border>
<Border Width="200" Background="PaleGreen" BorderBrush="Black" BorderThickness="1"
DockPanel.Dock="Left">
<TextBlock Foreground="Black">Dock = "Left"</TextBlock>
</Border>
<Border Background="White" BorderBrush="Black" BorderThickness="1">
<TextBlock Foreground="Black">This will fill the remaining space</TextBlock>
</Border>
</DockPanel>
Note the use of the DockPanel.Dock attached properties.
<DockPanel Grid.Row="1" LastChildFill="True" HorizontalAlignment="Stretch">
<DockPanel Width="400" LastChildFill="False" HorizontalAlignment="Left">
<Button x:Name="btnRefresh" Content="Refersh"
Height="35" DockPanel.Dock="Bottom" />
<TextBlock Width="400" />
</DockPanel>

I want to have different color to each side of a border in WPF XAML. How can i do this.
<Border BorderThickness="1,2,3,4" BorderBrush="Blue"></Border>
A bit hacky, but it works.
<Grid>
<Border BorderThickness="1,0,0,0" BorderBrush="Blue"/>
<Border BorderThickness="0,2,0,0" BorderBrush="Red"/>
<Border BorderThickness="0,0,3,0" BorderBrush="Green"/>
<Border BorderThickness="0,0,0,4" BorderBrush="Orange"/>
</Grid>
Probably better to create your own Decorator.
Maybe?
<DockPanel LastChildFill="True">
<Rectangle Fill="Red" DockPanel.Dock="Top" Height="2"/>
<Rectangle Fill="Yellow" DockPanel.Dock="Left" Width="2"/>
<Rectangle Fill="Green" DockPanel.Dock="Right" Width="2"/>
<Rectangle Fill="Blue" DockPanel.Dock="Bottom" Height="2"/>
<Rectangle Fill="Wheat"/>
</DockPanel>
There is a hacky way that using four Border https://stackoverflow.com/a/1797045/5229294
<Border BorderThickness="0,0,0,10" BorderBrush="Green">
<Border BorderThickness="0,0,10,0" BorderBrush="Blue">
<Grid>
<Button>Hello</Button>
</Grid>
</Border>
</Border>
I would like to reproduce this effect :
How can I do with xaml ?
(note that the text can be variable)
Thanks in advance for your help
You can easily achieve this with a combination of Border and Grid panels:
<Grid Width="200" Height="200" VerticalAlignment="Center" HorizontalAlignment="Center">
<Border BorderThickness="1" BorderBrush="Black" Margin="0,7,0,0">
<TextBlock Text="Lorem Ipsum..." Margin="20"/>
</Border>
<Border Background="White" Margin="10,0,10,0" HorizontalAlignment="Left" VerticalAlignment="Top">
<TextBlock Text="My Title" />
</Border>
</Grid>
Is there a way to make the shadow of the first control in a StackPanel appear on top of the second control?
I'm having trouble with this, look at the picture!
alt text http://img2.imageshack.us/img2/7073/issuef.png
Code sample:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib">
<Grid>
<StackPanel>
<Border Height="100" Width="100" Background="Red">
<Border.BitmapEffect>
<DropShadowBitmapEffect Color="Black" Direction="270" ShadowDepth="3" Opacity="1" Softness="2" />
</Border.BitmapEffect>
</Border>
<Border Height="100" Width="100" Background="blue">
</Border>
</StackPanel>
</Grid>
</Page>
You can do use Panel.ZIndex="0" in each of the Borders to set the z order of the items directly from the XAML.
<StackPanel>
<Border Height="100" Width="100" Background="Red" Panel.ZIndex="1">
<Border.BitmapEffect>
<DropShadowBitmapEffect Color="Black" Direction="270" ShadowDepth="3" Opacity="1" Softness="2" />
</Border.BitmapEffect>
</Border>
<Border Height="100" Width="100" Background="blue" Panel.ZIndex="0">
</Border>
</StackPanel>
Or you can use StackPanel.SetZIndex(object, value) if you wanted to do it from code.
