This is my code:
<telerik:RadComboBox Height="30" HorizontalAlignment="Left" Margin="126,63,0,0" Name="RadComboBox1" VerticalAlignment="Top" Width="262">
<telerik:RadComboBoxItem Content="Item 1" />
<telerik:RadComboBoxItem Content="Item 2" Visibility="Collapsed"/>
<telerik:RadComboBoxItem Content="Item 3" />
</telerik:RadComboBox>
But Item 2 not collapse.
Thanks,
