如何在UserControl组件上查找WPF中的所有控件

Question

我可以获取Form上的所有UI控件，但如何在某个UserControl上找到控件？

Answer 1

You can use Linq operator OfType and Controls property

var controls = YourForm
               .YourUserControl
               .Controls.OfType<TextBox>();
foreach(var control in controls)
{
    ....
}

Answer 2

您可以查看UserControl的FindName（字符串）方法

Answer 3

If you only want to look in the immediate object you can do FindName :

object foundControl = someParentControl.FindName("nameOfChild");

or if you want recursive ways then you can look at this post here: How can I find WPF controls by name or type?
