Create Custom Round Button in Windows 10

Create new Windows 10 project to know how to create windows 10 projects refer my previous article:

• Develop Apps For Windows 10

Now create one normal button as shown like below



XAML Code.

<Button Height="200" Width="200" Content="Tap Here" HorizontalAlignment="Center" Click="Button_Click"/>

Now add the below style in your page resource area. It looks like below:

<Page
x:Class="CustomCircleButton.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:CustomCircleButton"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
    <Page.Resources>
        <Style x:Key="CircleButton" TargetType="Button">
            <Setter Property="Background">
                <Setter.Value>
                    <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
                        <GradientStop Offset="0" Color="Blue"/>
                        <GradientStop Offset="1" Color="BlueViolet"/>
                    </LinearGradientBrush>
                </Setter.Value>
            </Setter>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Grid>
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="Disabled"/>
                                    <VisualState x:Name="Normal"/>
                                    <VisualState x:Name="MouseOver"/>
                                    <VisualState x:Name="Pressed">
                                        <Storyboard>
                                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Inner" Storyboard.TargetProperty="(ScaleTransform.ScaleY)">
                                                <DiscreteObjectKeyFrame KeyTime="0:0:0.0" Value="1"/>
                                            </ObjectAnimationUsingKeyFrames>
                                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Outer" Storyboard.TargetProperty="(ScaleTransform.ScaleY)">
                                                <DiscreteObjectKeyFrame KeyTime="0:0:0.0" Value="-1"/>
                                            </ObjectAnimationUsingKeyFrames>
                                        </Storyboard>
                                    </VisualState>
                                </VisualStateGroup>
                                <VisualStateGroup x:Name="FocusStates">
                                    <VisualState x:Name="Focused"/>
                                    <VisualState x:Name="Unfocused"/>
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>
                            <Ellipse Margin="4" Fill="{TemplateBinding Background}" RenderTransformOrigin="0.5,0.5">
                                <Ellipse.RenderTransform>
                                    <ScaleTransform ScaleY="1" x:Name="Outer"/>
                                </Ellipse.RenderTransform>
                            </Ellipse>
                            <Ellipse Margin="20" Fill="{TemplateBinding Background}" RenderTransformOrigin="0.5,0.5">
                                <Ellipse.RenderTransform>
                                    <ScaleTransform ScaleY="-1" x:Name="Inner"/>
                                </Ellipse.RenderTransform>
                            </Ellipse>
                            <ContentPresenter x:Name="content" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Page.Resources>

Now add this style to the simple button already we created:

<Button Height="200" Width="200" Content="Tap Here" HorizontalAlignment="Center" Style="{StaticResource CircleButton}" Click="Button_Click"/>
</Grid>

Now your button looks like below screen.



Now run the app and check how it looks in windows 10 desktop and simulator
