• Support for displaying complete forms or specific form sections
• Automatic save functionality with error handling
• Configurable cancel behavior with automatic change reversion
• Dynamic form component loading using MemberJunction's class factory system
• Customizable dialog dimensions and appearance
• TypeScript support with full type safety
• Integration with MemberJunction entity management system

Usage Examples

Basic Usage

<mj-entity-form-dialog
  [Record]="myEntityRecord"
  [Visible]="showDialog"
  (DialogClosed)="onDialogClosed($event)">
</mj-entity-form-dialog>

Complete Form Mode

Display the entire form for an entity:

<mj-entity-form-dialog
  Title="Edit User"
  [Record]="userRecord"
  Mode="complete"
  [Visible]="showDialog"
  [Width]="800"
  [Height]="600"
  [HandleSave]="true"
  [AutoRevertOnCancel]="true"
  (DialogClosed)="onDialogClosed($event)">
</mj-entity-form-dialog>

Section Mode

Display only a specific section of a form:

<mj-entity-form-dialog
  Title="Edit User Details"
  [Record]="userRecord"
  Mode="section"
  SectionName="details"
  [Visible]="showDialog"
  [Width]="500"
  [Height]="350"
  [HandleSave]="true"
  [AutoRevertOnCancel]="true"
  (DialogClosed)="onDialogClosed($event)">
</mj-entity-form-dialog>

Component Implementation

import { Component } from '@angular/core';
import { BaseEntity, Metadata } from '@memberjunction/core';

@Component({
  selector: 'app-user-management',
  template: `
    <button (click)="editUser()">Edit User</button>
    
    <mj-entity-form-dialog
      Title="Edit User"
      [Record]="userRecord"
      [Visible]="showDialog"
      [HandleSave]="true"
      [AutoRevertOnCancel]="true"
      (DialogClosed)="onDialogClosed($event)">
    </mj-entity-form-dialog>
  `
})
export class UserManagementComponent {
  userRecord: BaseEntity | null = null;
  showDialog = false;

  async editUser() {
    // Load user record using MemberJunction metadata system
    const md = new Metadata();
    this.userRecord = await md.GetEntityObject('Users');
    await this.userRecord.Load(userId);
    
    // Show the dialog
    this.showDialog = true;
  }

  onDialogClosed(result: 'Save' | 'Cancel') {
    if (result === 'Save') {
      // Handle successful save
      console.log('User saved successfully');
      // Refresh your UI or perform other actions
    } else {
      // Handle cancel - changes are automatically reverted if AutoRevertOnCancel is true
      console.log('Edit cancelled');
    }
    
    // Hide the dialog
    this.showDialog = false;
  }
}

API Reference

Input Properties

Output Events

Public Methods

ShowForm()

Programmatically shows the form. This is automatically called when the Visible property is set to true.

@ViewChild(EntityFormDialogComponent) formDialog!: EntityFormDialogComponent;

showFormProgrammatically() {
  this.formDialog.ShowForm();
}

CloseWindow(status: 'Save' | 'Cancel')

Programmatically closes the dialog with the specified status.

closeDialogProgrammatically() {
  this.formDialog.CloseWindow('Cancel');
}

Form Component Registration

The dialog dynamically loads form components based on the entity type and mode. These components must be registered with MemberJunction's class factory system:

For Complete Mode

Register a subclass of BaseFormComponent with the entity name:

import { RegisterClass } from '@memberjunction/global';
import { BaseFormComponent } from '@memberjunction/ng-base-forms';

@RegisterClass(BaseFormComponent, 'Users')
export class UserFormComponent extends BaseFormComponent {
  // Your form implementation
}

For Section Mode

Register a subclass of BaseFormSectionComponent with the pattern EntityName.SectionName:

import { RegisterClass } from '@memberjunction/global';
import { BaseFormSectionComponent } from '@memberjunction/ng-base-forms';

@RegisterClass(BaseFormSectionComponent, 'Users.details')
export class UserDetailsSectionComponent extends BaseFormSectionComponent {
  // Your section implementation
}

Error Handling

The component includes built-in error handling for save operations:

• If HandleSave is true and the save operation fails, the component will:
  1. Display an error notification using SharedService
  2. Automatically revert the changes to prevent data corruption
  3. Still emit the DialogClosed event with 'Save' status

Best Practices

1. Always provide a Record: The Record property is required and must be a valid BaseEntity instance
2. Handle the DialogClosed event: Always implement a handler to manage dialog visibility
3. Use proper entity loading: Load entities using MemberJunction's Metadata system
4. Register form components: Ensure your custom form components are properly registered
5. Consider dialog dimensions: Adjust Width and Height based on your form complexity

Integration with Other MemberJunction Packages

This package integrates seamlessly with:

• @memberjunction/core: For entity management
• @memberjunction/ng-base-forms: For form component base classes
• @memberjunction/ng-shared: For notification services
• @memberjunction/global: For class factory registration

Building

To build the package:

npm run build

The package uses Angular's ngc compiler and outputs to the dist directory.
