Hi to all,

I don't understand wich property I have to set a not-editable combobox.

I've attached view in readonly-mode also. I hope it is clarifier.

I tryed with trigger and set IsReadOnly property, but ComboBox is still editable (I can't edit, but I can selected by dropdown)

 

01.<Style x:Key="FieldLongComboBoxStyle" TargetType="telerik:RadComboBox" BasedOn="{StaticResource RadComboBoxStyle}">
02.        <Setter Property="Margin" Value="5"/>
03.        <Setter Property="IsEditable" Value="True"/>
04.        <Setter Property="ClearSelectionButtonVisibility" Value="Visible"/>
05.        <Setter Property="ClearSelectionButtonContent" Value="Cancella selezione"/>
06.        <Setter Property="TextSearchMode" Value="StartsWith"/>
07.        <Setter Property="EmptyText" Value="Valore non selezionato"/>
08.        <Setter Property="Width" Value="200"/>
09.        <Setter Property="HorizontalAlignment" Value="Left"/>
10.        <Style.Triggers>
11.            <DataTrigger Binding="{Binding CantUpdateModel}" Value="True">
12.                <Setter Property="IsReadOnly" Value="True"/>
13.            </DataTrigger>
14.            <DataTrigger Binding="{Binding CantUpdateModel}" Value="False">
15.                <Setter Property="IsReadOnly" Value="False"/>
16.            </DataTrigger>
17.        </Style.Triggers>
18.    </Style>

Hello Dario,

From what I understand you wish to prevent users from typing and selecting items in the RadComboBox.

If my assumption is correct I suggest that you use IsEnabled="False" instead of IsReadOnly property in order to achieve the desired behavior.

I know.

I was thinking a different approach because I need to keep not-editability style.

If I disable a control, the content changes of style, making it unreadable. I would like this content to be readable.

I have to create a specific style that replaces the one for the disabled control, is it correct?

Hi Dario,

So if I understand correctly - you need the RadComboBox to be displayed normally, but behave as if it is not enabled (i.e. as if IsEnabled="False"). 
If so, you can use set the IsHitTestVisible property to False. Thus the control will not respond to user mouse input and disable the selection with click.
Let us know whether this approach works for you.

Ok it's works.

I just apply a style.

I made like appearance's control as Office2013 theme. (In this theme, if control has IsreadOnly = True shows FontWeight = Bold)

Thank you Polya.
