How is this normally handled? I have this xaml:
<Border Grid.Column="1" HorizontalAlignment="Right"
VerticalAlignment="Top" Margin="10,25,10,0" Opacity="0.7"
BorderBrush="Black" BorderThickness="1" CornerRadius="5">
<StackPanel>
<StackPanel.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
<GradientStop Color="LightGray" Offset="0.0" />
<GradientStop Color="Gray" Offset="1.0" />
</LinearGradientBrush>
</StackPanel.Background>
The top left and right corners of the StackPanel are LightGray, and appear to be on top of the Border, so that in the middle of the rounded Black corners is a LightGray pixel or two, breaking up the rounding. The bottom border is Gray instead of Black.
What I thought I would get with the code above is a StackPanel with rounded corners...
I would suggest putting the background on the Border and not the Stackpanel
<Border Grid.Column="1" HorizontalAlignment="Right"
VerticalAlignment="Top" Margin="10,25,10,0" Opacity="0.7"
BorderBrush="Black" BorderThickness="1" CornerRadius="5">
<Border.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
<GradientStop Color="LightGray" Offset="0.0" />
<GradientStop Color="Gray" Offset="1.0" />
</LinearGradientBrush>
</Border.Background>
<StackPanel>
<!-- Items here -->
</StackPanel>
</Border>

I'm aware there are probably similar questions to this one but I have no idea how to sort this out. I'm rather new to XAML and have written the following:
<Window.Resources>
<ControlTemplate x:Key="ButtonTemplate">
<Ellipse Height="300" StrokeThickness="2" Width="300" >
<Ellipse.Fill>
<SolidColorBrush Color="white" Opacity="0"/>
</Ellipse.Fill>
<Ellipse.Stroke>
<LinearGradientBrush EndPoint="1,1" StartPoint="0,0">
<GradientStop Color="Red" Offset="0.1"/>
<GradientStop Color="Orange" Offset="0.35"/>
<GradientStop Color="SeaGreen" Offset="0.7"/>
<GradientStop Color="DarkBlue" Offset="0.95"/>
</LinearGradientBrush>
</Ellipse.Stroke>
</Ellipse>
</ControlTemplate>
</Window.Resources>
<Grid>
<Button Height="320" Width="320" Margin="200,100,200,100" Background="White" BorderThickness="0">
<Button.Foreground>
<LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
<GradientStop Color="Crimson" Offset="0.1" />
<GradientStop Color="SeaGreen" Offset="0.9" />
</LinearGradientBrush>
</Button.Foreground>
<Button.Content>
<TextBlock FontSize="30">TEST BUTTON</TextBlock>
</Button.Content>
</Button>
</Grid>
Putting the circle in a template seems to be the universally agreed way to start going about getting a circular border on the button, but nothing seems to work from there for me. I've left the template disconnected from the button here because it doesn't work, rather it seems to just overlay a solid circle on top of what is otherwise a working button. Can someone help me out?
You should specify the TargetType and add a ContentPresenter to the ControlTemplate:
<ControlTemplate x:Key="ButtonTemplate" TargetType="Button">
<Grid>
<Ellipse Height="300" StrokeThickness="2" Width="300" >
<Ellipse.Fill>
<SolidColorBrush Color="White" Opacity="0"/>
</Ellipse.Fill>
<Ellipse.Stroke>
<LinearGradientBrush EndPoint="1,1" StartPoint="0,0">
<GradientStop Color="Red" Offset="0.1"/>
<GradientStop Color="Orange" Offset="0.35"/>
<GradientStop Color="SeaGreen" Offset="0.7"/>
<GradientStop Color="DarkBlue" Offset="0.95"/>
</LinearGradientBrush>
</Ellipse.Stroke>
</Ellipse>
<ContentPresenter Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Margin="{TemplateBinding Padding}" RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</ControlTemplate>
And don't forget to apply the custom template by setting the Template property of the Button:
<Button Height="320" Width="320" Background="White" BorderThickness="0"
Template="{StaticResource ButtonTemplate}">
<Button.Foreground>
<LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
<GradientStop Color="Crimson" Offset="0.1" />
<GradientStop Color="SeaGreen" Offset="0.9" />
</LinearGradientBrush>
</Button.Foreground>
<Button.Content>
<TextBlock FontSize="30">TEST BUTTON</TextBlock>
</Button.Content>
</Button>
I would like to have a group of radio buttons which the circles for un-selected and selected mode are changed to circle icons that I designed.
It that possible to do that in WPF?
Thanks in advance
Create a style and override the default template for RadioButtons. Something like this:
<Window.Resources>
<Style TargetType="RadioButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<BulletDecorator Background="Transparent">
<BulletDecorator.Bullet>
<Grid Width="13" Height="13">
<Ellipse x:Name="Border" StrokeThickness="2">
<Ellipse.Stroke>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Green" Offset="0" />
<GradientStop Color="Pink" Offset="1" />
</LinearGradientBrush>
</Ellipse.Stroke>
<Ellipse.Fill>
<LinearGradientBrush StartPoint="0,0"
EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStopCollection>
<GradientStop Color="Orange" />
<GradientStop Color="Red"
Offset="1.0" />
</GradientStopCollection>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</Ellipse.Fill>
</Ellipse>
<Ellipse x:Name="CheckMark"
Margin="4"
Visibility="Collapsed">
<Ellipse.Fill>
<SolidColorBrush Color="Purple" />
</Ellipse.Fill>
</Ellipse>
</Grid>
</BulletDecorator.Bullet>
<ContentPresenter Margin="4,0,0,0"
VerticalAlignment="Center"
HorizontalAlignment="Left"
RecognizesAccessKey="True" />
</BulletDecorator>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
Yes, of course, it is possible. You can override default ControlTemplate and create style for your own radiobutton. Here is an example, you can also use Style Snooper to see the WPF built-in radio button style (a big piece of XAML code:) )
I'm trying to create a rounded end progress bar with a beveled border. I've got the progress bar looking like what I want but I'm having difficulty with making the border seemed beveled.
Can anyone help me out with this please?

Can anyone help me to get the border looking like the image? Many thanks.
It looks to me as though the main thing you're missing is the gradient brush on the border itself.
If you omit BorderBrush="#1D4276" and instead include something like the below, you'll be a lot closer:
<Border.BorderBrush>
<LinearGradientBrush EndPoint="0.5,0.9" StartPoint="0.5,0">
<GradientStop Color="#FFEBEFFA" Offset="0.9"/>
<GradientStop Color="#FF226494"/>
</LinearGradientBrush>
</Border.BorderBrush>
I want to set background of a grid using a style. I style I'm setting the Background Property of the grid.
But I have a border filled with LinearGradientFill and a Path which also has LinearGradientFill in it.
But I'm not able to combine both.
Below is sample code. I want to create it as a style.
<Grid>
<Border BorderBrush="Black" BorderThickness="2">
<Border.Background>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0.953" />
<GradientStop Color="White" Offset="0" />
</LinearGradientBrush>
</Border.Background>
</Border>
<Path Data="M 0,0 C 0,620 10,10 560,0" Height="60" VerticalAlignment="Top">
<Path.Fill>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0" />
<GradientStop Color="White" Offset="0.779" />
</LinearGradientBrush>
</Path.Fill>
</Path>
</Grid>
It gives me an error as:
The Property 'Value' is set more than once.
Archie,
You need to use a Template in order to place arbitrary XAML into a Style. Unfortuately, only Controls have Templates, and Grids and Borders are not Controls. But there is a solution. Although not as clean as you would like, the following XAMl should accomplish your goal. You paste the following XAML into Charles Petzold's XAML Cruncher to see the results:
<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="400" Height="400">
<UserControl.Resources>
<!-- A ContentControl template that defines your background -->
<ControlTemplate x:Key="BackgroundTemplate" TargetType="ContentControl">
<Grid>
<Border BorderBrush="Black" BorderThickness="2">
<Border.Background>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0.953" />
<GradientStop Color="White" Offset="0" />
</LinearGradientBrush>
</Border.Background>
</Border>
<Path Data="M 0,0 C 0,620 10,10 560,0" Height="60" VerticalAlignment="Top">
<Path.Fill>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Black" Offset="0" />
<GradientStop Color="White" Offset="0.779" />
</LinearGradientBrush>
</Path.Fill>
</Path>
</Grid>
</ControlTemplate>
<!-- A ContentControl Style that references the background template -->
<Style x:Key="BackgroundStyle" TargetType="ContentControl">
<Setter Property="Template" Value="{StaticResource BackgroundTemplate}" />
</Style>
</UserControl.Resources>
<!-- Typical usage; place the background ContentControl behind your body content -->
<Grid x:Name="LayoutRoot">
<ContentControl Style="{StaticResource BackgroundStyle}" />
<TextBlock Text="Your Content" Foreground="Red" FontSize="36" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</UserControl>
When I add a dropshadow bitmap effect to a rectangle, the dropshadow takes into account the transparency of the rectangle (makes sense). Is there a way to render a dropshadow on a transparent rectangle 'as if' the rectangle were opaque? ie what would appear is a rectangle-shaped 'hole', with a dropshadow.
Here is the XAML for a transparent rectangle with a dropshadow - nothing is displayed:
<Rectangle Fill="Transparent" Margin="10" Width="100" Height="100">
<Rectangle.BitmapEffect>
<DropShadowBitmapEffect/>
</Rectangle.BitmapEffect>
</Rectangle>
Drop this into Kaxaml. It creates a transparent Rectangle of size 500x500, with a SystemDropShadowChrome Decorator. The drop shadow's clip is set to exclude the Rectangle's region.
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:theme="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Canvas>
<theme:SystemDropShadowChrome Margin="0,0,5,5">
<Rectangle Width="500" Height="500" Fill="transparent"/>
<theme:SystemDropShadowChrome.Clip>
<CombinedGeometry GeometryCombineMode="Exclude">
<CombinedGeometry.Geometry1>
<RectangleGeometry Rect="0,0,505,505"/>
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<RectangleGeometry Rect="0,0,500,500"/>
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</theme:SystemDropShadowChrome.Clip>
</theme:SystemDropShadowChrome>
</Canvas>
</Page>
If you want your drop shadow to have rounded corners, then set the CornerRadius of the SystemDropShadowChrome to whatever (let's say 10), then Geometry1's Left and Top values to 10, then the RadiusX and RadiusY of each RectangleGeometry to 10.
I'd love to see better solution, but here is what I usually do (beware: creepy code ahead).
Wrap rectangle to three-four rectangles, and play with stroke color, making it darker and darker as it goes to original rectangle. Here is the code:
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<Rectangle
Width="106"
Height="106"
Stroke="#10000000"
StrokeThickness="1"/>
<Rectangle
Width="104"
Height="104"
Stroke="#5C000000"
StrokeThickness="1"/>
<Rectangle
Width="102"
Height="102"
Stroke="#AC000000"
StrokeThickness="1"/>
<Rectangle
Width="100"
Height="100"
Fill="Transparent"
Stroke="#FF000000"
StrokeThickness="1">
</Rectangle>
</Grid>
</Page>
This gives you:

Another approach would be with borders - it's better because you don't have to specify dimensions, when you put them inside Grid.
And the best approach (never seen implemented though): custom pixel shader, which makes what you want.
Well, here is one long-winded way to implement a rectangular 'drop-shadow' without using a bitmap effect. In this case the centre of the 'shadow rectangle' is coloured in, but it could be set to transparent to give you a 'halo' style drop shadow (i.e., equal all the way round - not offset)

wrap the rectangle in a border. and add a shadow to the border. you'll get the same effect.
