我有一个3x3矩阵网格。如果特定单元格上的用户，如何在单击后识别单元格坐标？

请指教。谢谢 PJ

假设你正在设计一个井字游戏风格的游戏，并且所讨论的网格是标准的WPF网格，我想你最好将控件放在每个单独的单元格中。这样你可以为每个事件挂钩鼠标事件，如下所示：

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Grid ShowGridLines="True">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition />
            <RowDefinition />
        </Grid.RowDefinitions>

        <Button Grid.Column="0" Grid.Row="0" Click="ButtonClick" />
        <Button Grid.Column="1" Grid.Row="0" Click="ButtonClick" />
        <Button Grid.Column="2" Grid.Row="0" Click="ButtonClick" />

        <Button Grid.Column="0" Grid.Row="1" Click="ButtonClick" />
        <Button Grid.Column="1" Grid.Row="1" Click="ButtonClick" />
        <Button Grid.Column="2" Grid.Row="1" Click="ButtonClick" />

        <Button Grid.Column="0" Grid.Row="2" Click="ButtonClick" />
        <Button Grid.Column="1" Grid.Row="2" Click="ButtonClick" />
        <Button Grid.Column="2" Grid.Row="2" Click="ButtonClick" />

    </Grid>
</Window>

在您的代码隐藏中：

private void ButtonClick(object sender, RoutedEventArgs e)
{
    Button _btn = sender as Button;

    int _row = (int)_btn.GetValue(Grid.RowProperty);
    int _column = (int)_btn.GetValue(Grid.ColumnProperty);
    MessageBox.Show(string.Format("Button clicked at column {0}, row {1}", _column, _row));
}

如何识别在WPF网格上点击了哪个单元格？
