我有10x10 Grid
。在每个空间中,我添加了一个标签,我添加了一个moused双击事件处理程序。因此,当我双击标签时,它应该显示Row
和Column
数字,但我只获得两个属性的0。
这是代码......(是的,我为每个标签设置了Grid.SetRow
和Grid.SetColumn
)
private void grid_Checked(object sender, MouseButtonEventArgs e)
{
MessageBox.Show(Grid.GetRow(e.Source as UIElement).ToString());
}

您确定所有内容都已正确连接吗?以下适用于我:
XAML:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" MouseDown="Label_MouseDown">
Label 0, 0
</Label>
<Label Grid.Row="0" Grid.Column="1" MouseDown="Label_MouseDown">
Label 0, 1
</Label>
<Label Grid.Row="0" Grid.Column="2" MouseDown="Label_MouseDown">
Label 0, 2
</Label>
<Label Grid.Row="1" Grid.Column="0" MouseDown="Label_MouseDown">
Label 1, 0
</Label>
<Label Grid.Row="1" Grid.Column="1" MouseDown="Label_MouseDown">
Label 1, 1
</Label>
<Label Grid.Row="1" Grid.Column="2" MouseDown="Label_MouseDown">
Label 1, 2
</Label>
<Label Grid.Row="2" Grid.Column="0" MouseDown="Label_MouseDown">
Label 2, 0
</Label>
<Label Grid.Row="2" Grid.Column="1" MouseDown="Label_MouseDown">
Label 2, 1
</Label>
<Label Grid.Row="2" Grid.Column="2" MouseDown="Label_MouseDown">
Label 2, 2
</Label>
</Grid>
C#:
private void Label_MouseDown(object sender, MouseButtonEventArgs e)
{
var label = e.Source as UIElement;
var row = Grid.GetRow(label);
var col = Grid.GetColumn(label);
MessageBox.Show(string.Format("{0},{1}", row, col));
}
当我点击其中一个标签时,MessageBox
包含正确的行和列。

您可能需要使用e.OriginalSource而不是e.Source。作为路由事件的已检查事件将在路由树时更改e.Source
。
