Getting the Item container corresponding to the selected item in XAML – Windows Store App

By | June 25, 2014

While building Apps using XAML, in many instances you may encounter this problem where you need to get an access for the container element from an ItemControl elements. For an example, you have GridView Control, and which has some grouped element as part of Item DataTemplate. If you handle only the GridItemClick event with command pattern (Using ICommand), you won’t be able to get access of the original sender directly (as it passes only ItemClickEventArgs). Which was the child element control of the GridView. On those scenarios you can use ContainerFromItem method that’s return the actual container corresponding to the specified item.

The ContainerFromItem method returns DependencyObject by accepting the item passed into it.

public void OnGridItemClick(ItemClickEventArgs obj)
if (obj != null )
GridView gridView = (GridView)obj.OriginalSource;
var selectedItem = gridView.<strong>ContainerFromItem</strong>(obj.ClickedItem);
item = (GridViewItem)selectedItem;
// Do stuff here

As shown in the above code block, OnGridItemClick, command execute on click of GridItems. where OnGridItemClick is nothing but a DelegateCommand defined as follows.

public ICommand GridViewItemClickCommand { get; private set; }
GridViewItemClickCommand = new DelegateCommand<ItemClickEventArgs>(OnGridItemClick);

And which is being called as,

Command="{Binding GridViewItemClickCommand , ElementName=pageRoot}" CommandParameter="{Binding ClickedItem}" />

This ContainerFromItem is quite helpful when you want to handle some of the operation depends on the sender object, and want to operate something on the UIElement.

You can also use ContainerFromIndex(), that does the same operation by accepting index rather the item.
