How to retrieve the name of a Panorama-Item at runtime?

Question

I am programmatically adding items to my Panorama Control called PanoramaCC.

//function to create the panorama items in our view
private void showPanorama(string panoramaName)
{
    //create the panorama item and define it
    PanoramaItem genItem = new PanoramaItem();
    genItem.Height = 265;
    genItem.Width = 440;
    genItem.Tap += new EventHandler<System.Windows.Input.GestureEventArgs>(PanoramaItem_Tap);
    genItem.Name = panoramaName;

    //create the stackpanel for the panoramaitem
    StackPanel genStack = new StackPanel();
    genStack.Orientation = System.Windows.Controls.Orientation.Horizontal;
    //margin to be done
    genStack.Margin = new Thickness(0, -20, 0, 20);

    //load the image
    Image genImg = new Image();
    genImg.Height = 220;
    genImg.Width = 400;
    genImg.Stretch = System.Windows.Media.Stretch.Fill;
    genImg.Margin = new Thickness(20, 5, 20, 5);

    string path = "Assets/AppGraphics/CreditCards/" + panoramaName.ToString() + "Front.png";
    Uri uriR = new Uri(path, UriKind.Relative);
    BitmapImage imgSource = new BitmapImage(uriR);
    genImg.Source = imgSource;

    //add image into stackpanel
    genStack.Children.Add(genImg);
    //add stackpanel to the panoramaitem
    genItem.Content = genStack;
    //add the panoramaitem to the panoramaview
    this.PanoramaCC.Items.Add(genItem);
}

The issue I have is that during runtime I want to retrieve the name of the panoramaItem I am currently looking at and do something with it. I've managed to retrieve the name through the tap event for navigation purposes, string name = ((PanoramaItem)sender).Name; but this is a diffrent scenario. I want to retrieve the name and then delete the item with the corresponding name. Pressing a button should delete the currently selected panoramaItem, is what I'm trying to achieve.

You can get the current PanoramaItem by using the SelectedItem property. You don't need to get the name to delete it.

PanoramaItem currentItem = myPanorama.SelectedItem as PanoramaItem;
if(currentItem != null)
{
   //if you want the name for other reasons
   string name = currentItem.Name;

   //Items returns an ItemsCollection object
   myPanorama.Items.Remove(currentItem);       
}

derp im facepalming hard right now. i saw the selectedItem for the panoramaControl but my brain didnt recognize it. Thanks – r wank Mar 22 '13 at 13:45
Any idea how I get the PanoramaItem when the SelectedItem is a model class? I just use an ItemTemplate and data binding so my list of model objects is shown as a PanoramaItem which means that SelectedItem as well as Items only refer to my model class(es). Meaning the above code always result in currentItem being null. – WarrenFaith Jun 26 '13 at 15:10
I've not tried retrieving the SelectedItem from a panorama item but [this behaviour](http://geoffwebbercross.blogspot.co.uk/2011/12/wp7-mvvm-panorama-selectedindex-binding.html) might help as well as [this workaround](http://stackoverflow.com/questions/14260701/windows-phone-8-panorama-selectionchanged-databinding). – keyboardP Jun 26 '13 at 21:06
I already use the workaround you linked. Anyway I created a new [question](http://stackoverflow.com/questions/17340869/get-image-in-currently-selected-panoramaitem), maybe you have time to take a look. – WarrenFaith Jun 27 '13 at 10:36
