The Smart Tag provides you with extended capabilities that simplify how to specify properties.

Application Theme

The Application Theme applies the selected theme (Office2019Colorful is the default theme) to the entire application at design time and runtime.

When you apply a theme, Smart Tag generates and adds the following code to your application.

App.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
       <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
           <section name="DXThemeManager" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" 
                 allowExeDefinition="MachineToLocalUser" requirePermission="false" />
       </sectionGroup>
    </configSections>
    <userSettings>
       <DXThemeManager>
           <setting name="ApplicationThemeName" serializeAs="String">
               <value>Office2016White</value>
           </setting>
       </DXThemeManager>
    </userSettings>
</configuration>

App.xaml

<Application x:Class="DXDesignTime.App"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            StartupUri="MainWindow.xaml" Startup="OnAppStartup_UpdateThemeName">
    <Application.Resources>

    </Application.Resources>
</Application>

App.xaml.cs

public partial class App : Application {
    private void OnAppStartup_UpdateThemeName(object sender, StartupEventArgs e) {
       DevExpress.Xpf.Core.ApplicationThemeHelper.UpdateApplicationThemeName();
    }
}

App.xaml.vb

Public Partial Class App Inherits Application
    Private Sub OnAppStartup_UpdateThemeName(sender As Object, e As StartupEventArgs)
        DevExpress.Xpf.Core.ApplicationThemeHelper.UpdateApplicationThemeName()
    End Sub
End Class

Data Context

When you use the Smart Tag DataContext property line, Smart Tag analyzes the object that is set. If Smart Tag considers that this is a POCO object, the DataContext property is set through the ViewModelSource class.

XAML

DataContext="{dxmvvm:ViewModelSource ViewModel:MainViewModel}"

Otherwise, the DataContext property is set to the chosen object in the regular manner.

Image Gallery

A special predefined list that is populated with images found in the application’s solution or from the DevExpress.Images.v20.2.dll assembly. The library contains common images that are referenced by multiple DevExpress controls. Refer to the DevExpress Image Gallery topic for more information.

Convert to ThemedWindow

You can click the Smart Tag’s Convert to ThemedWindow element (available when a window is selected) to convert the current window to a ThemedWindow.

Smart Tag automatically will change XAML code and CS code.
