How to delete items from a list in Windows Phone 8?

I have created an app. One of the features in the app is making a list and saving to Isolated Storage.

To the point, my problem is with deleting items from the list. To clarify, the user of the app can add items to list, and then save it. I am also using a LongListMultiSelector, which I downloaded from the web. What happens here is you can check items in a special boxes that pops-up (LongListMultiSelector feature). Up to this point, every feature works well. I want the user to be able to check the checkboxes, and press delete button, much like Windows Phone Hotmail, and rid of them. This is the part where I am having trouble.

So I click the trash can button which should function as a delete button. I have the following code for it.

 private void button3_Click(object sender, EventArgs e)
    {
        while (LLMS.SelectedItems.Count > 0)
        {
            source.Remove((MainList)LLMS.SelectedItems[0]);
            InitializeComponent();

        }
    }

LLMS represents the LongListMultiSelector. MainList is class and the list.

What happens is the app freezes up and stops working, though no pop-up comes up.

You can use this lines of code:

    void OnRemoveClick(object sender, EventArgs e)
    {
        IList source = MainList.ItemsSource as IList;

        while (MainList.SelectedItems.Count > 0)
        {
            source.Remove((**ObjectName**)MainList.SelectedItems[0]);
        }
    }
