如何识别WPF网格上点击哪个单元格？ [英] Ways to identify which cell was clicked on WPF Grid?

问题描述

我有一个3x3矩阵网格。如果一个用户在特定的单元格上，我怎样才能识别单元格后的单元格？

请指教。感谢

解决方案

假设您正在设计一个tic-tac-toe风格的游戏，并且所讨论的网格是标准的WPF Grid，我想你最好在每个单独的单元格中放置一个控件。这样，您可以将鼠标事件挂接到每个鼠标事件上，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 =Window1Height =300Width =300> 
< Grid ShowGridLines =True> 
< Grid.ColumnDefinitions> 
< ColumnDefinition /> 
< ColumnDefinition /> 
< ColumnDefinition /> 
< /Grid.ColumnDefinitions> 
< Grid.RowDefinitions> 
< RowDefinition /> 
< RowDefinition /> 
< RowDefinition /> 
< /Grid.RowDefinitions> 
 
< Button Grid.Column =0Grid.Row =0Click =ButtonClick/> 
< Button Grid.Column =1Grid.Row =0Click =ButtonClick/> 
< Button Grid.Column =2Grid.Row =0Click =ButtonClick/> 
 
< Button Grid.Column =0Grid.Row =1Click =ButtonClick/> 
< Button Grid.Column =1Grid.Row =1Click =ButtonClick/> 
< Button Grid.Column =2Grid.Row =1Click =ButtonClick/> 
 
< Button Grid.Column =0Grid.Row =2Click =ButtonClick/> 
< Button Grid.Column =1Grid.Row =2Click =ButtonClick/> 
< Button Grid.Column =2Grid.Row =2Click =ButtonClick/> 
 
< / Grid> 
< / Window> 
  

而在您的代码隐藏中：

<$私人无效ButtonClick（对象发件人，RoutedEventArgs e）
{
按钮_btn =发件人为按钮;

int _row =（int）_btn.GetValue（Grid.RowProperty）;
int _column =（int）_btn.GetValue（Grid.ColumnProperty）;
MessageBox.Show（string.Format（点击列{0}，行{1}，_column，_row））;
}

I have a 3x3 matrix grid. If a user on particular cell, how can I identify the cell cordinates after click?

Please advise. thanks PJ

解决方案

Assuming you're designing a tic-tac-toe style game, and the grid in question is the standard WPF Grid, I'd imagine you'd be best putting a control in each separate cell. That way you can hook into mouse events for each, like so:

<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>

And in your code-behind:

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));
}
