JScript does not support events.
<object SelectionChanged="SelectionChangedEventHandler" .../>
This event occurs whenever there is a change to a selection. A selection can be changed not only by user interaction but also by binding as well as other set values.
The following example shows how to attach the SelectionChanged event to a list box control.
<TextBox Name="tb" Width="140" Height="30"></TextBox>
<ListBox Name="lb" Width="100" Height="55" SelectionChanged="PrintText" SelectionMode="Single">
<ListBoxItem>Item 1</ListBoxItem>
<ListBoxItem>Item 2</ListBoxItem>
<ListBoxItem>Item 3</ListBoxItem>
<ListBoxItem>Item 4</ListBoxItem>
<ListBoxItem>Item 5</ListBoxItem>
<ListBoxItem>Item 6</ListBoxItem>
<ListBoxItem>Item 7</ListBoxItem>
<ListBoxItem>Item 8</ListBoxItem>
<ListBoxItem>Item 9</ListBoxItem>
<ListBoxItem>Item 10</ListBoxItem>
</ListBox>
The following example shows how to handle the SelectionChanged event.
Private Sub PrintText(ByVal sender As Object, ByVal e As SelectionChangedEventArgs)
Dim lbsender As ListBox
Dim li As ListBoxItem
lbsender = CType(sender, ListBox)
li = CType(lbsender.SelectedItem, ListBoxItem)
tb.Text = " You selected " & li.Content.ToString & "."
End Sub
void PrintText(object sender, SelectionChangedEventArgs args)
{
ListBoxItem lbi = ((sender as ListBox).SelectedItem as ListBoxItem);
tb.Text = " You selected " + lbi.Content.ToString() + ".";
}
