ExplainFormulaBehavior Class

SECURITY-RELATED CONSIDERATIONS

This API includes automatic prompt-injection protection for text and document-based AI-powered extensions. The system appends security instructions to each AI request to ensure that external or user-provided content is treated as untrusted data.

Prompt Injection Protection in AI Extensions

Generates a detailed explanation of the formula used in a worksheet cell (clarifying its purpose and function).

Namespace: DevExpress.AIIntegration.WinForms

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

Declaration

C#

public sealed class ExplainFormulaBehavior :
    ChangeTextBehaviorBase

VB.NET

Public NotInheritable Class ExplainFormulaBehavior
    Inherits ChangeTextBehaviorBase

Remarks

The following example registers the ExplainFormulaBehavior and assigns it to the WinForms Spreadsheet control:

C#

using DevExpress.AIIntegration.WinForms;

  //...
public SpreadsheetForm() {
    InitializeComponent();
    behaviorManager1.Attach<ExplainFormulaBehavior>(spreadsheetControl1);
}

VB.NET

Imports DevExpress.AIIntegration.WinForms

'...
Public Sub New()
InitializeComponent()
behaviorManager1.Attach(Of ExplainFormulaBehavior)(spreadsheetControl1)
End Sub

Note

Call the BehaviorInitializer.Initialize() method at application startup if your project targets the .NET Framework and you create AI-powered behaviors in code. Otherwise, an exception is thrown.

internal static class Program {
    [STAThread]
    static void Main() {
        //...
        // The Initialize() method forcibly initializes the behavior manager in .NET Framework apps.
        DevExpress.AIIntegration.WinForms.BehaviorInitializer.Initialize();
        Application.Run(new Form1());
    }
}
