Hi Thiago,

We don't recommend using StartEndDatePicker.EndPicker property outside RadScheduler.  You can check this example  about data validation of RadDateTimePicker control.

Hi Yana,

But i'd like to disable de manssage when i use StartEndDatePicker.EndPicker property inside RadScheduler.
Because, i'm using this template . Are there some property that i need to set in this part?

<Grid DataContext="{TemplateBinding EditedAppointment}" Background="{TemplateBinding Background}" Width="430" Height="300">
                            <Grid.RowDefinitions>
                               <RowDefinition Height="Auto" />
                               <RowDefinition Height="Auto" />
                               <RowDefinition Height="Auto" />
                               <RowDefinition Height="Auto" />
                               <RowDefinition Height="*" MinHeight="100" />
                               <RowDefinition Height="Auto" />
                           </Grid.RowDefinitions>
                           <Grid.ColumnDefinitions>
                               <ColumnDefinition Width="Auto" MinWidth="100" />
                               <ColumnDefinition Width="*" MinWidth="315"/>
                           </Grid.ColumnDefinitions>

                           <Label Target="{Binding ElementName=Subject}" Content="Subject" />
                           <TextBox x:Name="Subject" Grid.Column="1" TabIndex="0" Text="{Binding Path=Subject}" MaxLength="255" Margin="10, 10, 20, 2" />

                           <Label Grid.Row="1" Target="{Binding ElementName=StartDateTime}" Content="Start" />
                           <telerik:DateTimePicker x:Name="StartDateTime" Grid.Row="1"  Grid.Column="1" Margin="10, 10, 0, 2"

                                     IsEnabled="False"    SelectedDateTime="{Binding Path=End, Mode=TwoWay}" />

                           <CheckBox Grid.Row="3" Grid.Column="1" HorizontalAlignment="Left"

                           <Label Grid.Row="4" Target="{Binding ElementName=Body}" Content="Body" />
                           <TextBox Name="Body" Grid.Row="4"  Grid.Column="1" Text="{Binding Path=Body}" TextWrapping ="NoWrap"

                           <StackPanel Grid.Row="5" Grid.Column="1" Orientation="Horizontal" Margin="10, 10, 0, 10">
                               <Button Command="telerik:RadSchedulerCommands.SaveAppointment" Content="Save and Close" />
                               <Button Command="telerik:RadSchedulerCommands.EditRecurrenceRule" Margin="10, 0, 0, 0" Content="Edit recurrence" />
                               <Button Command="telerik:RadSchedulerCommands.EditParentAppointment" Margin="10, 0, 0, 0" Content="Edit parent" />
                           </StackPanel>
</Grid>

I'm using WPF controls not SilverLight controls like your example.
Thank you

Yana?? Did you forget my problem??
I need your help!

Hello Thiago Ferreira,

This message in the RadScheduler is internally set and cannot be easily overridden. You can replace scheduler datepickers with RadDatePickers in the template. I've attached an example to demonstrate the approach. Please try it and let us know how it goes.
