Auto Incrementing ID Module

WARNING

Starting with DevExpress Version 25.1, you should migrate to the new Llamachant.ExpressApp modules instead. Support for this module will end soon.

Supported Platforms: ✅ WinForms, ✅ WebForms, ✅ Blazor

The Auto Incrementing ID Module allows developers to quickly add incrementing IDs to business objects.

Getting Started

1. Install LlamachantFramework.AutoIncrementingID.Module from NuGet
2. Include LlamachantFrameworkAutoIncrementingIDModule in your .Module project

public DXApplication1Module() {
    RequiredModuleTypes.Add(typeof(LlamachantFrameworkAutoIncrementingIDModule));
}

You can define SQL query-based event handlers for trigger control:

public override void Setup(XafApplication application) {
    base.Setup(application);
    application.SetupComplete += Application_SetupComplete;
}

private void Application_SetupComplete(object sender, EventArgs e) {
    var module = LlamachantFrameworkAutoIncrementingIDModule.FindAutoIncrementingModule(Application.Modules);
    if (module != null) {
        module.TriggerCreating += Module_TriggerCreating;
    }
}

private void Module_TriggerCreating(object sender, TriggerEventArgs e) {
    // Custom trigger logic here
}
}

Sample Object Implementation

[DefaultClassOptions]
public class Quote : BaseObject {
    public Quote(Session session) : base(session) { }

private int _ID;
    [AutoIncrement]
    public int ID {
        get => _ID;
        set => SetPropertyValue(nameof(ID), ref _ID, value);
    }

private string _CustomerName;
    public string CustomerName {
        get => _CustomerName;
        set => SetPropertyValue(nameof(CustomerName), ref _CustomerName, value);
    }
}

Add Parameter-Based Auto Increment Logic

Specify a unique field for ID tracking:

[AutoIncrement(nameof(CustomerName))]

Use multiple parameters and expressions:

[AutoIncrement(nameof(CustomerName), "GetDate([QuoteDate])")]

📸 [Screenshot Placeholder: Multi-Parameter Auto Increment]

This approach ensures IDs increment based on filtered groups or contextual uniqueness.
