  Hello Ramco,

  This should have resolved your issue ,

   if (this.delModel) {
          const modalElement = this.delModel.nativeElement as HTMLElement;
          const bootstrapModal = new bootstrap.Modal(modalElement);
          bootstrapModal.show();
      }

  Hello Ramco,

  You can check adding a console.log()

  @ViewChild('mydeleteModal') delModel: ElementRef | undefined;
  
  onDelete(Id: number) {
      debugger;
      console.log("delModel:", this.delModel); // Log delModel to see if it's defined
      if (this.delModel && this.delModel.nativeElement) {
          console.log("Element found:", this.delModel.nativeElement); // Log the element
          this.delModel.nativeElement.style.display = 'block';
      } else {
          console.log("Element not found or undefined."); // Log if the element is not found
      }
  }

  The issue might be related to the way the modal is being accessed and displayed. When using @ViewChild, ensure that the element is available in the DOM before trying to access it.

  To troubleshoot the issue, you can check if the ViewChild is correctly referencing the modal element. Additionally, make sure that the onDelete method is being called appropriately to trigger the modal display.

  Here's a revised version of the onDelete method that checks for the existence of delModel before attempting to display the modal:

  @ViewChild('mydeleteModal') delModel: ElementRef | undefined;
  
  onDelete(Id: number) {
      if (this.delModel?.nativeElement) {
          this.delModel.nativeElement.style.display = 'block';
      }
  }
  

  By verifying the element reference and method invocation, you can ensure that the delete modal displays correctly when triggered.

  If @ViewChild('mydeleteModal') delModel: ElementRef | undefined; is correctly referencing the delete modal element, and it's still not entering the if condition if (this.delModel) {, there might be a few reasons why this is happening:

  1. Timing Issue: Ensure that the onDelete method is called after the component and its view are initialized. If onDelete is called before the view is fully initialized, this.delModel might still be undefined.

  2. Element Not Found: If this.delModel is undefined, it could be that Angular couldn't find an element with the ID mydeleteModal in the template. Double-check that the ID matches exactly in your template HTML.

  3. Angular Change Detection: Make sure that onDelete method is being triggered within Angular's change detection cycle. If it's called outside of Angular's control, the view might not have been updated yet.

  4. Other Errors: Check your browser console for any errors that might be preventing the code from running as expected. There could be unrelated errors affecting the execution flow.

  To debug this further, you can try the following:

  • Check if this.delModel is undefined or null when the if condition is reached.
  • Ensure that onDelete is being called after the component and its view are fully initialized.
  • Verify that the element with the ID mydeleteModal exists in the template and is not being dynamically created or removed.
  • Check for any errors in the console or potential asynchronous operations that might affect the timing of the code execution.

  Hi Vikas

      model ViewChild is working fine.

       @ViewChild('myModal') model : ElementRef | undefined;

      @ViewChild('mydeleteModal') delModel : ElementRef | undefined;

    It is not going in 'If' condition . 

   if (this.delModel) {

  Thanks

  1. Check if the onDelete method is being called correctly and if the Id parameter is being passed correctly.
  2. Ensure that the ViewChild decorator is set up correctly to reference the modal element.
  3. Make sure that ElementRef is imported from @angular/core.

  Here's how you can fix the issue:

  import { Component, ElementRef, ViewChild } from '@angular/core';

  @Component({
    selector: 'app-your-component',
    templateUrl: './your-component.component.html',
    styleUrls: ['./your-component.component.css']
  })
  export class YourComponent {
    @ViewChild('mydeleteModal') delModel: ElementRef | undefined;

    onDelete(Id: number) {
      debugger;
      if (this.delModel) {
        // Use nativeElement properly to access DOM properties
        this.delModel.nativeElement.style.display = 'block';
      }
    }
  }
   

  In your HTML template, make sure the onDelete method is correctly bound to a button or an action that triggers the deletion process. Also, ensure that Id is being passed correctly to the onDelete method.

  
  Delete Item
   

  By making sure these steps are followed correctly, your modal should appear when the onDelete method is called. If the issue persists, try debugging further to see if there are any errors in the console or if the onDelete method is being called as expected.
