Ellipse in WPF:
<Ellipse Width="190" Height="90">
<Ellipse.Fill>
<LinearGradientBrush>
<GradientStop Offset="0" Color="Wheat"/>
<GradientStop Offset="1" Color="White" />
</LinearGradientBrush>
</Ellipse.Fill>
</Ellipse>
How to use Ellipse on button's background?
<Button Height="100" Grid.Row="1" Grid.Column="1" Width="200">
<Ellipse Width="190" Height="90">
<Ellipse.Fill>
<LinearGradientBrush>
<GradientStop Offset="0" Color="Wheat"/>
<GradientStop Offset="1" Color="White" />
</LinearGradientBrush>
</Ellipse.Fill>
</Ellipse>
</Button>
Now I am taking a simple example to show how to create Ellipse on button's background and also how to show the message on messagebox using WPF.
Example:
MainWindow.xaml:
<Window x:Class="test_WPF.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="58" />
<RowDefinition Height="122" />
<RowDefinition Height="131*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="50" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="Enter Name:" Grid.Row="0" Grid.Column="0" />
<TextBox x:Name="txtName" Grid.Row="0" Grid.Column="1" MinWidth="50"/>
<Button Height="100" Grid.Row="1" Grid.Column="1" Width="200" Click="Button_Click">
<Ellipse Width="190" Height="90">
<Ellipse.Fill>
<LinearGradientBrush>
<GradientStop Offset="0" Color="Wheat"/>
<GradientStop Offset="1" Color="White" />
</LinearGradientBrush>
</Ellipse.Fill>
</Ellipse>
</Button>
</Grid>
</Window>
Design view:
MainWindow.xaml.cs:
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.Windows
Imports System.Windows.Controls
Imports System.Windows.Data
Imports System.Windows.Documents
Imports System.Windows.Input
Imports System.Windows.Media
Imports System.Windows.Media.Imaging
Imports System.Windows.Navigation
Imports System.Windows.Shapes
Namespace test_WPF
''' <summary>
''' Interaction logic for MainWindow.xaml
''' </summary>
Partial Public Class MainWindow
Inherits Window
Public Sub New()
InitializeComponent()
End Sub
Private Sub Button_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
MessageBox.Show(String.Format("Hello {0}", Me.txtName.Text))
End Sub
End Class
End Namespace
Output: Now debug this application and enter your name then the message box shows as follows:
