c# - Xamarin Grid 如何知道按下了哪个按钮

Question

我正在使用 xamarin 表单网格，当单击网格按钮时我有一个事件处理程序按钮我不知道如何知道按钮在哪一行和哪一列。

这是我的网格代码:

<Grid x:Name="grid" ColumnSpacing="6" RowSpacing="5" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Constant=-20}"
                RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent,
                         Property=Height,
                         Factor=0.50 }">

<Grid.RowDefinitions>
  <RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
    <Button x:Name="button1" Text="1" Grid.Row="0" Grid.Column="0" Clicked="handle_clicked"/>
    <Button x:Name="button2" Text="2" Grid.Row="0" Grid.Column="1" Clicked="handle_clicked"/>
    <Button x:Name="button3" Text="3" Grid.Row="0" Grid.Column="2" Clicked="handle_clicked"/>
    <Button x:Name="button4" Text="4" Grid.Row="0" Grid.Column="3" Clicked="handle_clicked"/>
    <Button x:Name="button5" Text="5" Grid.Row="0" Grid.Column="4" Clicked="handle_clicked"/>
    <Button x:Name="button6" Text="6" Grid.Row="0" Grid.Column="5" Clicked="handle_clicked"/>

    <Button x:Name="button7" Text="7" Grid.Row="1" Grid.Column="0" Clicked="handle_clicked"/>
    <Button x:Name="button8" Text="8" Grid.Row="1" Grid.Column="1" Clicked="handle_clicked"/>
    <Button x:Name="button9" Text="9" Grid.Row="1" Grid.Column="2" Clicked="handle_clicked"/>
    <Button x:Name="button10" Text="10" Grid.Row="1" Grid.Column="3" Clicked="handle_clicked"/>
    <Button x:Name="button11" Text="11" Grid.Row="1" Grid.Column="4" Clicked="handle_clicked"/>
    <Button x:Name="button12" Text="12" Grid.Row="1" Grid.Column="5" Clicked="handle_clicked"/>

    <Button x:Name="button13" Text="13" Grid.Row="2" Grid.Column="0" Clicked="handle_clicked"/>
    <Button x:Name="button14" Text="14" Grid.Row="2" Grid.Column="1" Clicked="handle_clicked"/>
    <Button x:Name="button15" Text="15" Grid.Row="2" Grid.Column="2" Clicked="handle_clicked"/>
    <Button x:Name="button16" Text="16" Grid.Row="2" Grid.Column="3" Clicked="handle_clicked"/>
    <Button x:Name="button17" Text="17" Grid.Row="2" Grid.Column="4" Clicked="handle_clicked"/>
    <Button x:Name="button18" Text="18" Grid.Row="2" Grid.Column="5" Clicked="handle_clicked"/>

    <Button x:Name="button19" Text="19" Grid.Row="3" Grid.Column="0" Clicked="handle_clicked"/>
    <Button x:Name="button20" Text="20" Grid.Row="3" Grid.Column="1" Clicked="handle_clicked"/>
    <Button x:Name="button21" Text="21" Grid.Row="3" Grid.Column="2" Clicked="handle_clicked"/>
    <Button x:Name="button22" Text="22" Grid.Row="3" Grid.Column="3" Clicked="handle_clicked"/>
    <Button x:Name="button23" Text="23" Grid.Row="3" Grid.Column="4" Clicked="handle_clicked"/>
    <Button x:Name="button24" Text="24" Grid.Row="3" Grid.Column="5" Clicked="handle_clicked"/>

    <Button x:Name="button25" Text="25" Grid.Row="4" Grid.Column="0" Clicked="handle_clicked"/>
    <Button x:Name="button26" Text="26" Grid.Row="4" Grid.Column="1" Clicked="handle_clicked"/>
    <Button x:Name="button27" Text="27" Grid.Row="4" Grid.Column="2" Clicked="handle_clicked"/>
    <Button x:Name="button28" Text="28" Grid.Row="4" Grid.Column="3" Clicked="handle_clicked"/>
    <Button x:Name="button29" Text="29" Grid.Row="4" Grid.Column="4" Clicked="handle_clicked"/>
    <Button x:Name="button30" Text="30" Grid.Row="4" Grid.Column="5" Clicked="handle_clicked"/>
</Grid>

和 eventHandler 代码:

void handle_clicked(Object sender, System.EventArgs e)
    {
        Button thebutton = (Button) sender;
        int row = ?;
        int column = ?;

        //Display picker view with options
        //Displaypickerview();

    }

谢谢您的帮助。

更新:

您的答案有效，但为什么 Grid 大写。

因为在我的网格代码中我有网格名称小写所以我认为你会使用小写所以你在我的网格中搜索按钮。

尝试这个:

Button theButton = (Button) sender;
int row = Grid.GetRow(theButton);
int column = Grid.GetColumn(theButton);
