Component API

Selector

mj-generic-dialog

Inputs

Outputs

Public Methods

Content Projection Slots

• Default slot: Content displayed in the dialog body
• custom-actions slot: Content projected into the dialog action area for custom buttons. Use the custom-actions attribute on any element to project it into this slot

Advanced Usage

Programmatic Control

You can control the dialog programmatically from the parent component:

import { Component, ViewChild } from '@angular/core';
import { GenericDialogComponent } from '@memberjunction/ng-generic-dialog';

@Component({
  selector: 'app-advanced-dialog',
  template: `
    <mj-generic-dialog #myDialog
      DialogTitle="Programmatic Control"
      [DialogVisible]="isDialogVisible"
      (DialogClosed)="onDialogClosed($event)">
      <div>Dialog content here</div>
    </mj-generic-dialog>
    
    <button (click)="openDialog()">Open Dialog</button>
    <button (click)="closeDialogProgrammatically(true)">Close with OK</button>
    <button (click)="closeDialogProgrammatically(false)">Close with Cancel</button>
  `
})
export class AdvancedDialogComponent {
  @ViewChild('myDialog') dialog!: GenericDialogComponent;
  isDialogVisible = false;
  
  openDialog() {
    this.isDialogVisible = true;
  }
  
  closeDialogProgrammatically(withOK: boolean) {
    if (withOK) {
      this.dialog.HandleOKClick();
    } else {
      this.dialog.HandleCancelClick();
    }
  }
  
  onDialogClosed(confirmed: boolean) {
    console.log('Dialog closed with:', confirmed ? 'OK' : 'Cancel');
  }
}

Data Refresh Pattern

The dialog automatically emits a RefreshData event when it becomes visible. Use this to load fresh data:

@Component({
  selector: 'app-data-dialog',
  template: `
    <mj-generic-dialog
      DialogTitle="User Details"
      [DialogVisible]="showUserDialog"
      (DialogClosed)="onDialogClosed($event)"
      (RefreshData)="loadUserData()">
      
      <div *ngIf="userData">
        <p>Name: {{ userData.name }}</p>
        <p>Email: {{ userData.email }}</p>
        <p>Last Updated: {{ userData.lastUpdated }}</p>
      </div>
      
      <div *ngIf="loading">Loading...</div>
    </mj-generic-dialog>
  `
})
export class DataDialogComponent {
  showUserDialog = false;
  userData: any = null;
  loading = false;
  
  loadUserData() {
    this.loading = true;
    // Simulate API call
    setTimeout(() => {
      this.userData = {
        name: 'John Doe',
        email: 'john@example.com',
        lastUpdated: new Date().toLocaleString()
      };
      this.loading = false;
    }, 1000);
  }
  
  onDialogClosed(confirmed: boolean) {
    this.showUserDialog = false;
    if (confirmed) {
      console.log('Saving user data...');
    }
  }
}

Styling

The component uses Kendo UI dialog and button components, which inherit the active Kendo theme. You can apply custom styles to the content within the dialog using standard CSS or Angular styling approaches.

Custom Styling Example

/* In your component styles */
:host ::ng-deep .k-dialog-title {
  background-color: #3f51b5;
  color: white;
}

:host ::ng-deep .k-dialog-content {
  padding: 20px;
}

.settings-form {
  display: flex;
  flex-direction: column;
  gap: 15px;
}

.form-group {
  display: flex;
  align-items: center;
  gap: 10px;
}

Integration with MemberJunction

Common Patterns

Confirmation Dialog

<mj-generic-dialog
  DialogTitle="Confirm Delete"
  DialogWidth="400px"
  DialogHeight="200px"
  [DialogVisible]="showDeleteConfirm"
  OKButtonText="Delete"
  CancelButtonText="Keep"
  (DialogClosed)="handleDeleteConfirmation($event)">
  <div>
    <p>Are you sure you want to delete this item?</p>
    <p><strong>This action cannot be undone.</strong></p>
  </div>
</mj-generic-dialog>

Form Dialog

<mj-generic-dialog
  DialogTitle="Edit User"
  DialogWidth="600px"
  [DialogVisible]="showEditDialog"
  [ShowOKButton]="false"
  [ShowCancelButton]="false"
  (RefreshData)="loadUserForEdit()">
  
  <form [formGroup]="userForm">
    <!-- Form fields -->
  </form>
  
  <div custom-actions>
    <button kendoButton 
            [disabled]="!userForm.valid" 
            (click)="saveUser()" 
            themeColor="primary">
      Save Changes
    </button>
    <button kendoButton (click)="cancelEdit()">Cancel</button>
  </div>
</mj-generic-dialog>

Troubleshooting

Dialog Not Showing

• Ensure DialogVisible is properly bound to a boolean property
• Check that the module is imported correctly
• Verify Kendo UI dependencies are installed

Custom Actions Not Appearing

• Use the custom-actions attribute on the container element
• Ensure the element is a direct child of mj-generic-dialog

Dialog Closes Immediately

• Check for any code that might be setting DialogVisible to false
• Ensure event handlers aren't causing unintended state changes
