Remove specified Children element of a Grid
提问by Nicolò Carpignoli
I need to remove at runtime a specified element of a Grid (grid1). This is the code where i add the elements.
我需要在运行时删除网格 (grid1) 的指定元素。这是我添加元素的代码。
examControls.Add(excontrol); // add the element on the ArrayList
excontrol.Margin = new Thickness(x, y + margin, 0, 0);
grid1.Children.Add(excontrol);
How can i remove at runtime a specified "excontrol" element (added at runtime) ?
如何在运行时删除指定的“excontrol”元素（在运行时添加）？
Thanks in advance
提前致谢

If you keep a record of the control you can simply do:
如果您保留控制记录，您可以简单地执行以下操作：
grid1.Children.Remove(excontrol);
If you don't have a variable that holds the control you wish to remove you'll have to identify it in some way (Tag, Name), then find that control in the grid's children and then call Remove.
如果您没有包含要删除的控件的变量，则必须以某种方式（标记、名称）标识它，然后在网格的子项中找到该控件，然后调用Remove.

grid1.Children.Remove(excontrol) //edited per your edit -- this is exactly what ChrisF posted though

或者
grid1.Children.RemoveAt(index)
