WPF TextBlock单击事件

Question

我在我的wpf应用程序中的网格中创建了文本块.我知道如何创建click事件.但我不知道如何从那个细胞获得属性.我想要Grid.Row和Grid.Column的属性.我怎样才能做到这一点？

<Window x:Class="TicTacToe.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Tic-Tac-Toe" Height="356" Width="475">
    <Grid VerticalAlignment="Top" ShowGridLines="True" Height="313" Margin="10,10,2,0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
        </Grid.RowDefinitions>
        <TextBlock Grid.Row="0" Grid.Column="0" Text="o" TextAlignment="Center" FontSize="72" FontFamily="Lucida Bright" FontWeight="Bold"></TextBlock>
        <TextBlock Grid.Row="0" Grid.Column="1" MouseLeftButtonDown="ChoosePosition" ></TextBlock>
        <TextBlock Grid.Row="0" Grid.Column="2" ></TextBlock>
        <TextBlock Grid.Row="1" Grid.Column="0" ></TextBlock>
        <TextBlock Grid.Row="1" Grid.Column="1" ></TextBlock>
        <TextBlock Grid.Row="1" Grid.Column="2" ></TextBlock>
        <TextBlock Grid.Row="2" Grid.Column="0" ></TextBlock>
        <TextBlock Grid.Row="2" Grid.Column="1" ></TextBlock>
        <TextBlock Grid.Row="2" Grid.Column="2" ></TextBlock>

    </Grid>

</Window>

 private void ChoosePosition(object sender, MouseButtonEventArgs e)
        {
        }

由于Grid.Row和Grid.Column是Grid类的附加属性,您可以使用以下语法获取它们:

int row = Grid.GetRow(myTextBox);
int column = Grid.GetColumn(myTextBox);

在您的情况下,您可以在Click处理程序中转换sender参数,因此它看起来像这样:

var myTextBox = sender as TextBox;
if(myTextBox != null) {
   int row = Grid.GetRow(myTextBox);
   int column = Grid.GetColumn(myTextBox);
}
