    Hi, 

    I want to know if there is anyway i can DISABLE a selection for a particular item in the dropdown list?

    i have a list of objects bind to the dropdown list, and i want to disable some of the items from selection using data trigger based on one of the object's property.

    thanks

    Hi Shengwei,

    I'm afraid that currently there isn't a straightforward approach to achieve the described scenario.

    Thank you for your feedback, we will consider this particular case for the future releases of the control.

    Thank you for your reply.

    Currently i had a "half" working solution which is to set the styling of RadListBoxItem since the dropdown is a radlistbox

    <modules:AutoCompleteItemToFocusableConverter x:Key="ac2fConverter"/>
    <Style TargetType="telerik:RadListBoxItem">
        <Style.Triggers>
            <DataTrigger Binding="{Binding Converter={StaticResource ac2fConverter}}" Value="False">
                <Setter Property="IsHitTestVisible" Value="False"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>

    but the above doesnot prevent the keydown selection however it does prevent cursor selection.

    or we can using 

    <Setter Property="IsEnabled" Value="False"/>

    however the styling of the individual item will be gone since it is disabled, i need to overwrite the default style for the disalbed.


    but thanks for your reply
