ItemPicker
RadChatPicker control provides ItemPickerContext that can be used to display a list of options the end user could choose from.
ItemPickerContext exposes the following properties you could use to provide a list of possible options to the user:
- ItemsSource - defines the data source used to generate the content of the ItemPicker control;
- SelectionMode - ItemPicker allows users to select one or many items out of the provides ItemsSource;
- SelectedItems - defines the currently selected items;
- SelectedItem - defines the last selected item;
Here is a quick example on how to user ItemPicker:
ItemPickerContext context = new ItemPickerContext
{
ItemsSource = new List<string>() { "2 days", "5 days", "7 days", "Another period" }
};
PickerItem pickerItem = new PickerItem { Context = context, HeaderText = "Select an item" };
chat.Items.Add(pickerItem);
context.PropertyChanged += (s, e) =>
{
if (e.PropertyName == "SelectedItem")
{
if (context.SelectedItem != null)
{
chat.Items.Remove(pickerItem);
chat.Items.Add(new TextMessage { Author = chat.Author, Text = "" + context.SelectedItem });
}
}
};
