				VisibleRange="{Binding VisibleRange}" HighlightedItemsSource="{Binding HighlightedItems}" Grid.Row="1"
				Margin="0 6 0 0"
				PixelLength="{Binding PixelLenght, Mode=TwoWay}">
            <telerik:RadGanttView.Columns>
                <telerik:TreeColumnDefinition Header="Title" MemberBinding="{Binding Title}" Width="240">
                    <telerik:TreeColumnDefinition.CellEditTemplate>
                        <DataTemplate>
                            <TextBox Text="{Binding Title, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" telerik:TouchManager.TouchMode="None" />
                        </DataTemplate>
                    </telerik:TreeColumnDefinition.CellEditTemplate>
                </telerik:TreeColumnDefinition>
                <telerik:ColumnDefinition MemberBinding="{Binding Start}" Header="Start" Width="120">

                            <telerik:RadDateTimePicker SelectedValue="{Binding Start, Mode=TwoWay}" />
                        </DataTemplate>
                    </telerik:ColumnDefinition.CellEditTemplate>
                </telerik:ColumnDefinition>

I have created a sample project which is as close as in the provided image, but I could not recreate the mentioned issue, as it works correctly on my end. I have attached the project that I used for testing. So, could you edit it to match the behavior on your end and send it back?

Hello Onduty,

To fix this behavior, just add the following ResourceDictionary for the Telerik.Windows.Controls.Input dll in the App.xaml file. It should look as follows:

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Input.xaml" />

On to the observed behavior, the RadDateTimePicker control was visualized with the default theme, which is Office_Black. That is because the provided project uses the Xaml binaries. And the rest of the controls are being set with the Implicit Styles approach, which is used when the project refers to the NoXaml binaries. What I could recommend in the current scenario, is to use the NoXaml dlls and add the aforementioned ResourceDictionary.

More generally speaking, there are 2 ways to set a theme when using our products and they are:

  • using Style Manager (this approach is recommended when using the NoXaml binaries and their location is inside the Binaries.NoXaml folder)
  • using Implicit Styles (this approach is recommended when using Xaml binaries and they are inside the Binaries folder)

Finally, I have attached the provided project, which I modified to use the NoXaml assemblies and with the added ResourceDictionary.

Stenly
