Resource xaml for RadDatePicker

[Frank]

Hello,

im using Datepicker in RadGridView. Im going to write a Resource .xaml for all RadDatePickers. So that I have to change the property only in one .xaml if necessary. I tried this way:
 

<Setter Property="ErrorTooltipContent" Value="Error for Example">
           <DataTemplate>
                    <TextBlock Text="{Binding Path=ToolTipConten, ElementName=radDateTimePicker}"
                               FontWeight="Bold"
                               Foreground="Red"/>
                </DataTemplate>
           
        </Setter>


 But it doesnt work...Its the same with Watermarkcontent. How can I solve it?

Best regards
Christian

Hello Christian,

In order to set a DataTemplate to the WaterMark you need to apply it through the DateTimeWatermarkTemplate property, like so:

<Style x:Key="DatePickerStyle" TargetType="telerik:RadDateTimePicker">
           <Setter Property="DateTimeWatermarkTemplate">
               <Setter.Value>
                   <DataTemplate>
                       <TextBlock Text="WaterMarkText"
                              FontWeight="Bold"
                              Foreground="Red"/>
                   </DataTemplate>
               </Setter.Value>
           </Setter>
       </Style>

Also, in the DataTemplate binding with the ElementName set to the control is not supported, as it is in different namescope. Binding with ElementName can exist only if the name is inside the DataTemplate.
Unfortunately, there is no property to which the ErrorToolTip template can be set. You can only set the Content of the ErrorToolTip.

Hope this information helps.
