ValidationModule.InitializeRuleSet() Method
Initializes the RuleSet object assigned to the DevExpress.Persistent.Validation.Validator.RuleSet
property.
Namespace: DevExpress.ExpressApp.Validation
Assembly: DevExpress.ExpressApp.Validation.v24.1.dll
NuGet Package: DevExpress.ExpressApp.Validation
Declaration
Remarks
Note
In v23.1 and higher, you do not need to use the InitializeRuleSet
method in .NET Core-based applications (both Blazor and WinForms). All required initialization is done automatically.
The Validation Module calls this method on logon and when a user closes the Model Editor at runtime. To initialize validation rules before the main window is displayed and a user logs into the application, follow the steps below:
- Override the ModuleBase.Setup method in a platform-specific or platform-agnostic Module.
- In this overridden method, handle the XafApplication.SetupComplete event.
- In the event handler, access the Validation Module and call the InitializeRuleSet method.
File: MySolution.Module\Module.cs(.vb).
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Validation;
// ...
public sealed partial class MySolutionModule : ModuleBase {
public override void Setup(XafApplication application) {
base.Setup(application);
application.SetupComplete += Application_SetupComplete;
}
private void Application_SetupComplete(object sender, EventArgs e) {
ValidationModule module = (ValidationModule)Application.Modules.FindModule(typeof(ValidationModule));
if(module != null) {
module.InitializeRuleSet();
}
}
// ...
}
