如果不给itemspanel 结果会是下面这样子，如果不注释掉的话 是下面这样子（这是itempanel里面放wrappanel 的结果）

遍历listbox里面的item ，

for (int i = 0; i < listBox.Items.Count; i++)

        {

              ListBoxItem item = (ListBoxItem)listBox.ItemContainerGenerator.ContainerFromIndex(i);

            

   }

var itemview = listBox.SelectedItem as ItemsView;//ITEMTEMPLATE 的一个item 是 绑定的itemview ，listbox的itemsource 是list《itemview 》

var item = listBox.ItemContainerGenerator.ContainerFromItem(itemview) as ListBoxItem;

然后listbox 的item 里面还有个hold 事件来响应 触控事件

item.Hold += item_Hold;

 

获得listbox 的itemtemplate 模板里面的grid

private ChildType FindVisualChild<ChildType>(DependencyObject obj) where ChildType : DependencyObject

       {

           //if (obj != null)

           //{

               for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)

               {

                   DependencyObject child = VisualTreeHelper.GetChild(obj, i);

                   if (child != null && child is ChildType)

                       return child as ChildType;

                   else

                   {

                       ChildType childOfChild = FindVisualChild<ChildType>(child);

                       if (childOfChild != null)

                           return childOfChild;

                   }

               }

           //}

           return null;

       }

调用方法如下

   var grid = FindVisualChild<Grid>(item);

获得item 里面的grid

获得item里面的image可以这样调用

var obj=FindVisualChild<Image>(item);
