    <wj-flex-grid

              [ngStyle]="{ display: dp.isDetailVisible(row) ? '' : 'none' }"
              (click)="dp.hideDetail(row)"
              (click)="removeChildProcesses(item)"
            >
              <adp-icon iconType="fa-minus"></adp-icon>
            </a>
            <a
              [class.grid-link-selected]="isCellSelected(cell)"
              [ngStyle]="{
                display:
                  !dp?.isDetailVisible(row) || item.ISCHILDCHECK == 1
                    ? ''
                    : 'none'
              }"
              (click)="dp.showDetail(row, true)"
              (click)="showChildProcesses(item)"
            >
              <adp-icon iconType="fa-plus"></adp-icon>
            </a>
          </div>
        </ng-template>
      </wj-flex-grid-column>
  

  Please refer the screenshots and code which we are using to implement this feature ?
  
  Could anyone suggest demo for this ?

  Hi Soumya,

  Using FlexGridDetail provider automatically add icons to the row headers of the grid to expand/collapse the row details.
  
  Can you let us know whether you wish to customize the icons or your requirements are different?

  Regards,
  
  Ashwin

  Hi Ashwin

  I have implemented the same using FlexgridDetail.
  
  But, I am facing certain issues while implementing FlexgridDetail.
  
  Could you share some demo in stackblitz (Related to my code which is there on the top) ?

  Hi Soumya,

  You may use the wjFlexGridDetail directive to directly add the details in the HTML template. Please refer to the sample link below:

  HI Ashiwin

  ODataCollectionView is something which we can’t implement with our itemSource since we are not converting array of objects into ODataCollectionView.We are not at all using ODataCollectionView. We are simply referring to array of objects.

  Could you suggest some idea how to implement this feature by using custom elements to show or hide ?https://demos.wijmo.com/5/angular/rowdetails/rowdetails/

  I just need a stackblitz working solution of the above context.

  Hi Soumya,

  Refer to the sample link below that uses custom icons to show/hide the details:

  https://stackblitz.com/edit/angular-efauth

  Also, in the previous demo, the ODataCollectionView class is just used as an example. The same process can be followed even if you are using a CollectionView.

  Hi Shailesh,

  Can you let me know whether your requirement is to add inline editing in the main grid only or the main and detail grid both?

  Hi,

  We have created a sample for the in-line feature for edit and delete the main grid, however for add button can you please share more details. As per our understanding, you want to add rows on click of add button, so we have added an additional button outside the grid to add rows.
