如何确定选定的GridView项目？

Question

I have a gridView. instead of ItemTemplate I used user control for gridviewitems because I cant manage to trigger the button click event in the itemtemplate

here is my code

for (int i = 0; i < collection.Count(); i++)
{
     GridViewItem gridViewItem = new GridViewItem();
     gridViewItem.Tag = i;
     PhotoItem item = new PhotoItem();

     item.photoTitleTextBlock.Text = collection[i].Type.ToString();
     item.eraseButton.Click += (sender, args) => { itemSent(item); };

     gridViewItem.Content = item;
     gvIdTypes.Items.Add(gridViewItem);
}

in my userControl PhotoItem there are textblock, button and image textblock.text comes from collection if gridview item is selected(via gridView.selectionChanged event) web cam takes photo and puts on the image of the UserControl

how can I figure out which of the item is selected in the selectionChanged event

改用ItemClick ，然后您可以在ItemClickEventArgs访问ClickedItem
