有办法做到这一点.您可以使用它VisualTreeHelper来遍历屏幕上的所有对象.我使用的一种方便的方法(从网上某处获得)是FindControl方法:
public static T FindControl<T>(UIElement parent, Type targetType, string ControlName) where T : FrameworkElement
{
if (parent == null) return null;
if (parent.GetType() == targetType && ((T)parent).Name == ControlName)
{
return (T)parent;
}
T result = null;
int count = VisualTreeHelper.GetChildrenCount(parent);
for (int i = 0; i < count; i++)
{
UIElement child = (UIElement)VisualTreeHelper.GetChild(parent, i);
if (FindControl<T>(child, targetType, ControlName) != null)
{
result = FindControl<T>(child, targetType, ControlName);
break;
}
}
return result;
}

你可以像这样使用它:
var combo = ControlHelper.FindControl<ComboBox>(this, typeof(ComboBox), "ComboBox123");
