My ListBoxItems contain multiple TextBoxes like this:
<ListBox Name="myList" SelectionChanged="myList_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem>
<ListBoxItem.Content>
<StackPanel Orientation="Vertical">
<TextBlock Name="nameTextBlock"
Text="{Binding Name}"
/>
<TextBlock Name="ageTextBlock"
Text="{Binding Age}"
/>
<TextBlock Name="genderTextBlock"
Text="{Binding Gender}"
/>
<TextBlock Name="heightTextBlock"
Text="{Binding Height}"
/>
</StackPanel>
</ListBoxItem.Content>
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
When an item is clicked, I would like each TextBlock to be saved to IsolatedStorage under corresponding keys. Right now the closest I've gotten to this method is this:
private void mysList_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
ListBoxItem lbi = (ListBoxItem)myList.SelectedItem;
appSettings["name"] = (string)lbi.Content;
}
But, when clicked I get an InvalidCastException. As I understand it, it's basically due to me trying to convert all four textboxes into a single string (or something like that). So how do I save each TextBox's text field independently within the ListBoxItem to an IsolatedStorage key/value? Thanks again in advance.
