Event raised when selected tokens are removed through clear button in AutoCompleteView
Environment
Product Version | 2018.3.1109.1 |
Product | AutoCompleteView for Xamarin |
Description
This article shows which event you could handle when the end user removes any of the selected in RadAutoCompleteView tokens by tapping on the clear button.
Solution
You would need to subscribe to the CollectionChanged event of the Tokens collection of the AutoCompleteView control. Here is a quick snippet which demonstrates the approach:
autoCompleteView.Tokens.CollectionChanged += TokensCollectionChanged;
and the TokensCollectionChanged event handler:
private void TokensCollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
var removedTokens = e.OldItems;
}
Through the NotifyCollectionChangedEventArgs you could find the added/removed items from the collection.
