Validation (Data Driven)

NuGet Package Details

Package Name

Llamachant.ExpressApp.Validation

XPO

Llamachant.ExpressApp.Validation.Xpo

EF Core

Llamachant.ExpressApp.Validation.EF

Overview

The Validation module allows users to define and manage validation rules at runtime and persist them in the database. This mirrors the capabilities of built-in XAF validation attributes and rules but adds the ability to configure and modify them dynamically through the UI. With this module, users can enforce business logic and data integrity without needing to modify source code, offering a more adaptable and maintainable validation strategy.

TIP:

This module requires the XPO or EF specific module to be added to your solution to function.

Installation

Step 1: Install the Module

Install the relevant ORM-specific module:

Install-Package 'Llamachant.ExpressApp.Validation.Xpo'

Install-Package 'Llamachant.ExpressApp.Validation.EF'

Step 2: Register the Module

Register the relevant ORM-specific module (either Xpo or EF Core):

Module.cs

public override void Setup(XafApplication application) {
    base.Setup(application);
    // Xpo:
    this.RequiredModuleTypes.Add(typeof(LlamachantFrameworkValidationModuleXpo));
    // EF Core:
    this.RequiredModuleTypes.Add(typeof(LlamachantFrameworkValidationModuleEF));
}

OR

Startup.cs

services.AddXaf(Configuration, builder => {
    builder.UseApplication<ExpressAppBlazorApplication>();
    builder.Modules
        // Xpo:
        .AddLlamachantFrameworkValidationModuleXpo();
        // EF Core:
        .AddLlamachantFrameworkValidationModuleEF();
});

Step 3: Create Appearance Rules

Once the module is installed and registered, you can create new Validation Rules at runtime.
