.NET MAUI TemplatedPicker Events
The TemplatedPicker for .NET MAUI exposes a SelectionChanged event which is raised when the user confirms the selected item.
Define the TemplatedPicker:
<telerik:RadTemplatedPicker SelectionChanged="RadTemplatedPicker_SelectionChanged" x:Name="picker">
<telerik:RadTemplatedPicker.SelectorTemplate>
<ControlTemplate>
<telerik:RadCalendar SelectedDate="{TemplateBinding SelectedValue, Mode=TwoWay}"/>
</ControlTemplate>
</telerik:RadTemplatedPicker.SelectorTemplate>
</telerik:RadTemplatedPicker>
Set the SelectionChanged event where the sender is the TemplatedPicker control.
private void RadTemplatedPicker_SelectionChanged(object sender, System.EventArgs e)
{
// implement your logic here
}
