我的网格有 2 行 2 列,我想动态地将一个文本块添加到第一行第二列。
这是我的代码,它不会引发异常,但不会显示任何内容
<Grid HorizontalAlignment="Left" Height="768" VerticalAlignment="Top" Width="1366">
<Grid.RowDefinitions>
<RowDefinition Height="150"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="250"/>
</Grid.ColumnDefinitions>
</Grid>
protected async override void OnNavigatedTo(NavigationEventArgs e)
{
TextBlock txt = new TextBlock();
txt.Width = 200;
txt.Height = 100;
txt.Foreground = new SolidColorBrush(Colors.Yellow);
var location = await InitializeLocationServices();
txt.Text = location;
Grid.SetRow(txt, 0);
Grid.SetColumn(txt, 1);
}
