Question

我需要在wpf的组框内添加多个按钮，但我不能。我需要为自动取款机创建带有所有数字的键盘，但是如果我尝试创建2号按钮，则1号按钮会消失。怎么了？

<Window x:Name="Win_Users" x:Class="ATM_Simulator.WindowUsers"

    <Button x:Name="btn_close" Content="Close" HorizontalAlignment="Left" Margin="393,239,0,0" VerticalAlignment="Top" Width="77"/>

您必须在GroupBox内放置一个容器，例如，网格是一个不错的选择：

<GroupBox x:Name="grbx_key_pad" Header="Key Pad" HorizontalAlignment="Left" Height="220" Margin="26,10,0,0" VerticalAlignment="Top" Width="189">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
            <ColumnDefinition/>
         </Grid.ColumnDefinitions> 
        <Button x:Name="btn_1" Grid.Column="0" Content="1" Width="29" Height="32"/>
        <Button x:Name="btn_2" Grid.Column="1" Content="2" Width="29" Height="32"/>
        <!-- more buttons -->
        <Button x:Name="btn_4" Grid.Row="1" Grid.Column="0" Content="4" Width="29" Height="32"/>
        <!-- yet more buttons -->
    </Grid>
</GroupBox>
