WPF C#代码中引用XAML中的控件

Posted 2022-12-15 bcbobo21cn

先在XAML中做一个Grid布局，运行如下；此grid有Name和ShowGridLines两个属性；

 可在C#代码中引用此grid，调用其方法，设置其属性；

为Button添加单击事件，在C#代码中写如下，

private void Button_Click_1(object sender, RoutedEventArgs e)
        
            grid1.ShowGridLines = false;
            grid1.Background = Brushes.Green;
        

 运行如下；

 XAML代码；

<Window x:Class="WpfApplication1.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 Name="grid1" ShowGridLines="True">
        <Grid.RowDefinitions>
            <RowDefinition ></RowDefinition>
            <RowDefinition ></RowDefinition>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100"></ColumnDefinition>
            <ColumnDefinition Width="Auto"></ColumnDefinition>
            <ColumnDefinition Width="50"></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <Button Grid.Row="0" Grid.Column="0" Margin="3">Left</Button>
        <Button Grid.Row="0" Grid.Column="2" Margin="3">Right</Button>
        <Button Grid.Row="1" Grid.Column="0" Margin="3" Click="Button_Click_1">Left</Button>
        <Button Grid.Row="1" Grid.Column="2" Margin="3">Right</Button>

        <GridSplitter Grid.Row="0" Grid.Column="1" Grid.RowSpan="2" Width="3" VerticalAlignment="Stretch"
                      HorizontalAlignment="Center" ShowsPreview="False"></GridSplitter>
    </Grid>
</Window>
