（控件类型）DataGrid。FinContrl（“控件名称”）

如果不能这样找到
//ContentPresenter pr=(ContentPresenter)this.dgSpecialPrice.Template;
//ComboBox cb = this.FindName("cbName") as ComboBox;
//DataGridBoundColumn list = (DataGridBoundColumn)dgSpecialPrice.ItemContainerGenerator.ContainerFromItem(dgSpecialPrice.Items.CurrentItem);
//ContentPresenter myContentPresenter = FindVisualChild<ContentPresenter>(list);
//DataTemplate myDataTemplate = myContentPresenter.ContentTemplate;
//ComboBox cb = (ComboBox)myDataTemplate.FindName("cbName", myContentPresenter);
private childItem FindVisualChild<childItem>(DependencyObject obj)where childItem : DependencyObject
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
{
DependencyObject child = VisualTreeHelper.GetChild(obj, i);
if (child != null && child is childItem)
return (childItem)child;
else
{
childItem childOfChild = FindVisualChild<childItem>(child);
if (childOfChild != null)
return childOfChild;
}
}
return null;
}
我是这样实现的
