Set DateTimeWatermarkContent from Style

[Gergely]

Hi

I wanted to set the default DateTimeWatermarkContent for RadDatePicker from Style. At first it seemed not working (the default "Enter date" text appeared), later I have defined the property for each RadDatePicker manually and later removed these manual overrides for some reason. Surprisingly, the Style definition seemed to work now, but only in Visual Studio (I could even change the default value and the designer followed the changes). However, when I have run the application, my style definition was not used ("Enter date", again). Even stranger that from this point on, the designer "forgot" to use the style again as well.

What am I doing wrong? It is possible to set this property from Style?

My code:

 <Window.Resources>

        <ResourceDictionary>

            <Style TargetType="telerik:RadDatePicker">

                <Setter Property="Culture" Value="hu-HU" />

                <Setter Property="MinWidth" Value="100" />

                <Setter Property="VerticalAlignment" Value="Center"/>

                <Setter Property="DateTimeWatermarkContent" Value=""/>

            </Style>

        </ResourceDictionary>

    </Window.Resources>
...
<telerik:RadDatePicker Grid.Column="1" Grid.Row="0"></telerik:RadDatePicker>
<telerik:RadDatePicker  Grid.Column="1" Grid.Row="2"></telerik:RadDatePicker>

...

Any ideas?

Thanks for the help in advance!

I am sorry, I should have written my question in DatePicker not in DateTimePicker thread. Anyway, I have found out that styleing the mentioned property seems to work if I use a DateTimePicker.

Hello Gergely,

Thank you for sharing the issue you are experiencing. This behavior is a known issue which has been reported as a bug. You can vote for it in our PITS list here.

Meanwhile, you can use the following syntax to set the DateTimeWatermarkContent property:

<Setter Property="DateTimeWatermarkTemplate">
     <Setter.Value>
         <DataTemplate>
             <TextBlock Text="My custom watermark" Opacity="0.5" />
         </DataTemplate>
     </Setter.Value>
 </Setter>

Please, contact us again should you have any further inquiries.

<Setter Property="DateTimeWatermarkTemplate"> 

     <Setter.Value> 

         <DataTemplate> 

             <TextBlock Text="My custom watermark" Opacity="0.5" /> 

         </DataTemplate> 

     </Setter.Value> 

 </Setter>

Work with Enabled control, but if it's disabled "Enter date" the notice is displayed

Hi Alexander,

I tested the case and the watermark content is behaving as expected in WPF even with the control disabled. However, since this was not the case with the Silverlight control, you can also try  setting both the DateTimeWatermarkTemplate as already mentioned, and the DateTimeWatermarkContent property in the same style.

I think this will do the job for you. Please, let me know if you need further assistance.
