allowDragging in flexgrid with custom ng-template for column

    I have a flexgrid (parent) where every row can be expanded, containing another nested grid (nested).

    Drag and drop reordering works fine in the nested grid by using [allowDragging]="'Rows'". However, the same does not work for the parent grid.

    In the parent grid, I have a custom expand/collapse button implementation due to row height issues when trying to use it out of the box:

    <wj-flex-grid-column [allowDragging]="'Rows'" [width]="30" align="center" cssClass="detail-icon" [isReadOnly]="true">
    <ng-template wjFlexGridCellTemplate let-cell="cell" cellType="Cell">
    <span (click)="dp.hideDetail(cell.row)" *ngIf="dp.isDetailVisible(cell.row)"><i class="fa fa-minus"></i></span>
    <span (click)="showDetails(dp, cell.row)" *ngIf="!dp.isDetailVisible(cell.row)"><i class="fa fa-plus"></i></span>
    </ng-template>
    </wj-flex-grid-column>


    The row isn't draggable in the parent. Can you advise how I can best achieve this?

    I'm unable to edit the original post for an update:

    Furthermore, I noticed that in the stackblitz sample (https://stackblitz.com/edit/angular-efauth) provided in this discussion: https://www.grapecity.com/forums/wijmo/how-to-implement-expand-an, when you add [allowDragging]="'Rows'" to each of the flexgrids, it only works in the nested one without the custom expand/collapse column.

    How can we get it working for the parent grid in this scenario?

    Hi anthcasey,

    In the forum link provided, the row headers are not displayed and the dragging is only performed by row headers. I have updated the sample so that rows of both the grids can be dragged:
