PromptToExpressionBehavior Class

Converts natural language into valid filter and unbound column expressions for data-aware WPF controls.

Namespace: DevExpress.AIIntegration.Wpf

Assembly: DevExpress.AIIntegration.Wpf.v26.1.dll

Declaration

C#

public class PromptToExpressionBehavior :
    AIBehavior

VB.NET

Public Class PromptToExpressionBehavior
    Inherits AIBehavior

Remarks

PromptToExpressionBehavior converts a natural language into valid filter and unbound column expressions for data-aware WPF controls. Users can describe the desired expression behavior using their natural language instead of writing complex expressions. The system sends the resulting prompt to the configured AI service that generates a valid expression for the control. The Expression Editor or Filter Editor displays and validates the result immediately.

When the PromptToExpressionBehavior object is attached to GridControl or TreeListControl, both Expression Editor and Filter Editor display the AI prompt UI. Use EnableInExpressionEditor and EnableInFilterEditor properties to explicitly specify if the AI prompt UI is visible in corresponding editors.

                 xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm">
       <dxg:GridControl ItemsSource="{Binding Employees}">
           <dxmvvm:Interaction.Behaviors>
               <dxai:PromptToExpressionBehavior
                   RetryAttemptCount="3"
                   Temperature="0.3"
