How to change Placeholder of RadChat

[Le]

Dear Telerik,

How can I change the placeholder of RadChat from 'Please entry a message' to other value binding to ViewModel like 'ABC...'. I have tried to use

<ContentPage.Resources>
   <Style TargetType="telerik:ChatEntry">
        <Setter Property="Placeholder" Value="ABC.." />
    </Style>
</ContentPage.Resources> --> But it made the theming of RadChat failed! Can you help tell me how to solve this?

Hi Le,

I think that the only missing piece is the BasedOn property.

When you declare a local implicit style in the page, it has a higher precedence than the implicit style declared in the Telerik xaml resources (they are merged in App.xaml). So the global Telerik style for the ChatEntry is not at all taken into account.

The way to go here is to base the custom style on the global style:

<Style TargetType="telerik:ChatEntry" BasedOn="{StaticResource RadEntryStyle}">

 

I tested this in one of our test examples and I get this output:

 

Let us know if this helps.
