copied!<p>This block of code feels like it might be confusing your display:</p> <pre><code> var row = this.GetCell(tableView, indexPath); (row as FamilysubgroupViewCell).ExpandCells(); tableView.ReloadRows(new[] { indexPath }, UITableViewRowAnimation.Automatic); </code></pre> <p>What this does is:</p> <ul> <li>get the current cell and tell it to expand</li> <li>then ask the table to reload the row (at which point a different cell instance might be used).</li> </ul> <p>I'd also worry that the line:</p> <pre><code> var context = this.DataContext as FamilySubTypeViewModel; </code></pre> <p>would link your cells sub-display to the current viewmodel - and this wouldn't update if the cell were reused (given a new viewmodel).</p> <p>One quick (and only slightly dirty) way around both of these problems would be to change the override for <code>GetOrCreateCellFor</code> to something like:</p> <pre><code>protected override UITableViewCell GetOrCreateCellFor(UITableView tableView, NSIndexPath indexPath, object item) { var cell = tableView.DequeueReusableCell(_key); cell.Frame = new RectangleF(cell.Frame.X, cell.Frame.Y, cell.Frame.Width, GetHeightForRow(tableView, indexPath)); ((MyCellType)cell).ShowExpandedState(expandableState[items[indexPath.Row]]); return cell; } </code></pre> <p>Where <code>ShowExpandedState(bool)</code> would be capable of resetting the cell's expanded area after reuse.</p> <hr> <p>Other options:</p> <ul> <li>Instead of this, you could simply return a different cell type for expanded versus non-expanded rows? </li> <li>Or you could put the expanded/non-expanded information in the Cell's ViewModel so that it can data-bind to that expanded state and update it's own layout? (you'd still need some mechanism to tell the table about the size change though)</li> </ul> <hr> <p>On: </p> <pre><code>this.Draw(this.Bounds); </code></pre> <p>I'm not too surprised this didn't work - generally you have to encourage the system to redraw views - using things like <code>SetNeedsDisplay</code> (and sometimes after child changes <code>SetNeedsLayout</code> too)</p>
