I am trying to remove selected item from one listbox and add that into new listbox as follows code

Binding on PageLoad:

Getting the records from database into a DataTable and bind that to Listbox.

```
lstBox1.DataContext = dtData;

```

Code Bind:

```
  List<object> _selecteditems = new List<object>();
  foreach (var item in lstBox1.SelectedItems)
  {
      _selecteditems.Add(item);
  }
  foreach (var item in _selecteditems)
  {
      lstBox1.Items.Remove(item);
      lstBox2.Items.Add(item);
  }

```

Design:

```
<ListBox Name="lstBox1" ItemsSource="{Binding}">
  <ListBox.ItemTemplate>
    <DataTemplate>
      <TextBlock Text="{Binding ID}"/>
    </DataTemplate>
   </ListBox.ItemTemplate>
</ListBox>

<ListBox Name="lstBox2" ItemsSource="{Binding}" >
  <ListBox.ItemTemplate>
     <DataTemplate>
        <TextBlock Text="{Binding ID}"/>
      </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>

```

I am getting an error when removeing the item "Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead."
