Integrate DevExpress AI-Powered Text Extensions into Console, WinForms, and WPF Apps

This example registers an Azure OpenAI service and uses AI APIs within a .NET 8 console application and adds AI-powered text processing features to the following DevExpress UI components:

• WinForms MemoEdit
• WinForms RichEdit
• WPF TextEdit
• WPF RichEditControl

Note

DevExpress does not provide a REST API or include built-in LLMs/SLMs. To use AI services, you need an active Azure/OpenAI subscription to obtain the necessary REST API endpoint, key, and model deployment name. This information must be added at application startup to register AI clients and enable DevExpress AI-powered features in your application.

Implementation Details

Install the following NuGet packages:

1. Azure.AI.OpenAI

2. DevExpress.AIIntegration

3. Microsoft.Extensions.AI.Ollama

4. Microsoft.Extensions.AI.OpenAI

Register AI Services

The following code in the Program.cs file registers an Azure AI service in the application:

// Modify the following lines to obtain and pass your personal Azure OpenAI credentials to the `Register~` method.
static string AzureOpenAIEndpoint { get { return Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT"); } }
static string AzureOpenAIKey { get { return Environment.GetEnvironmentVariable("AZURE_OPENAI_APIKEY"); } }
static string DeploymentName { get { return Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENTNAME"); } }

AIExtensionsContainerDefault defaultAIContainer;
public SampleAITextModifier()
{

    ///To register Ollama
    //OllamaChatClient ollamaChatClient = new OllamaChatClient("http://localhost:11434/api/chat", "yourModelName");
    //defaultAIContainer = AIExtensionsContainerConsole.CreateDefaultAIExtensionContainer(ollamaChatClient);

    ///To register Azure OpenAI
    AzureOpenAIClient azureOpenAIClient = new AzureOpenAIClient(new Uri(AzureOpenAIEndpoint),    
        new System.ClientModel.ApiKeyCredential(AzureOpenAIKey));
    defaultAIContainer = AIExtensionsContainerConsole.CreateDefaultAIExtensionContainer(azureOpenAIClient.AsChatClient(DeploymentName));
}

WinForms

Use the BehaviorManager component to activate AI-powered text transform extensions for DevExpress WinForms UI controls.

Drop the BehaviorManager component from the Toolbox onto a Form. Open the behavior manager's smart tag menu and click "Edit Behaviors" to edit behaviors. In the Behavior Collection Editor, create desired AI-powered text processing behaviors, attach them to corresponding UI controls, and configure behavior settings (for example, the Temperature):

Run the application. Select text in the MemoEdit or RichTextEdit control and invoke the context menu. The context menu will display an "AI Text Transform" submenu with AI-driven commands.

Click the desired command. AI will process the command and generate an answer. The AI-generated answer is displayed within a dialog. You can insert the answer directly into a document or text field with a single click. You can insert AI answers above/below the cursor, replace all content or selected text, or copy the answer to the clipboard.

WPF

To introduce AI-powered capabilities in DevExpress WPF UI controls, add the following namespaces to a Window:

xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm"
xmlns:wpf="clr-namespace:DevExpress.AIIntegration.Wpf;assembly=DevExpress.AIIntegration.Wpf.v24.2"
xmlns:desktop="clr-namespace:DevExpress.AIIntegration.Desktop;assembly=DevExpress.AIIntegration.Desktop.v24.2"

The following code snippet attaches AI-powered text processing behaviors to a DevExpress Text Editor:

<dxe:TextEdit TextWrapping="Wrap">
    <dxmvvm:Interaction.Behaviors>
        <wpf:SummarizeBehavior/>
        <wpf:ExplainBehavior/>
        <wpf:ShortenBehavior/>
        <wpf:ExpandBehavior />
        <wpf:ToneStyleBehavior />
        <wpf:ProofreadBehavior/>
        <wpf:RewriteStyleBehavior/>
        <wpf:CustomRequestBehavior/>
        <wpf:TranslateBehavior>
            <desktop:LanguageInfo Culture="de-DE"/>
            <desktop:LanguageInfo Culture="es-ES"/>
            <desktop:LanguageInfo Culture="pt-BR"/>
        </wpf:TranslateBehavior>
    </dxmvvm:Interaction.Behaviors>
</dxe:TextEdit>
