WPF TextBlock Click Event
提问by Antarr Byrd
I have create textblocks in my grid in my wpf application. I know how to create the click event. But I'm not sure how to get properties from that cell. The properties I want Grid.Row and Grid.Column. How can I do this?
我在 wpf 应用程序的网格中创建了文本块。我知道如何创建点击事件。但我不确定如何从该单元格获取属性。我想要Grid.Row 和Grid.Column 的属性。我怎样才能做到这一点？

As Grid.Row and Grid.Column are attached properties from the Grid class, you can get them using this syntax:
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);
In your case, you can cast the sender argument in the Click handler, so it would look like this:
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);
}

Have you checked the senderparameter? That will give you a reference to the textbox object which might be all you need depending on what you are trying to do.
你检查sender参数了吗？这将为您提供对文本框对象的引用，这可能是您所需要的，具体取决于您要执行的操作。

Just change TextBox to TextBlock
只需将 TextBox 更改为 TextBlock
