很简单用Grid5*4布局，填充Button
跨越多个单元格，设置控件的Grid.ColumnSpan Grid.RowSpan属性
1 <Grid Width="400" Grid.Row="1" Height="300" HorizontalAlignment="Center" VerticalAlignment="Center"> 2 <Grid.RowDefinitions> 3 <RowDefinition /> 4 <RowDefinition /> 5 <RowDefinition /> 6 <RowDefinition /> 7 </Grid.RowDefinitions> 8 <Grid.ColumnDefinitions> 9 <ColumnDefinition /> 10 <ColumnDefinition /> 11 <ColumnDefinition /> 12 <ColumnDefinition /> 13 <ColumnDefinition /> 14 </Grid.ColumnDefinitions> 15 <Button Content="1" Grid.Row="0" Grid.Column="0" Click="Button_Click"/> 16 <Button Content="2" Grid.Row="0" Grid.Column="1" Click="Button_Click"/> 17 <Button Content="3" Grid.Row="0" Grid.Column="2" Click="Button_Click"/> 18 <Button Content="4" Grid.Row="1" Grid.Column="0" Click="Button_Click"/> 19 <Button Content="5" Grid.Row="1" Grid.Column="1" Click="Button_Click"/> 20 <Button Content="6" Grid.Row="1" Grid.Column="2" Click="Button_Click"/> 21 <Button Content="7" Grid.Row="2" Grid.Column="0" Click="Button_Click"/> 22 <Button Content="8" Grid.Row="2" Grid.Column="1" Click="Button_Click"/> 23 <Button Content="9" Grid.Row="2" Grid.Column="2" Click="Button_Click"/> 24 <Button Content="0" Grid.Row="3" Grid.Column="0" Click="Button_Click"/> 25 <Button Content="."

设置input TextBox，Ouput TextBox，background属性为transparent，使得显示效果似乎是一个TextBox
