steve,

ok, i finally reproduced missing clicks on a cell and they are to do with IGSlideTabView.

Please run attached example and watch recorder screen. I really hope u can reproduce this problem (not just watching the video). this is my original problem and the reason I decided to adapt to ColumnDefinitions use for editing but seems the problem exists regardless.

1. in portrait mode - click cell next to a tab (say 5.6)
2. rotate into landscape mode
3. click again in on cells around cell 5.4 - PROBLEM!!!! behaving very erratic.

Thank you

Mark

steve,

thank you for your response.

I do not get any tap events when i get stuck. I need to click in a different areas of the cell to get it going again. 

Anyway, let me see if I can create for you more consistent scenario to demonstrate the problem I am having.

Thank you 

Mark

Hey Mark, 

I've watched the video a lot. I still have not been able to reproduce it though, and i'm using the sample you gave me... So i'm kind of operating blindly, so i really appreciate your patience. 

When you're clicking on a cell, and its not doing anything, is the Tapped event not firing at all? Maybe stick in a Console.WriteLine("Tapped") to see if thats the case. If its not firing, it means that gesture didn't get registered, or something else is capturing it, and that would be really puzzling.. 

One other thing i just noticed which we should fix, is to no use the RegisterGestures method. RegisterGestures will keep registering the same event over and over again. Which could potentially be causing issues, and may be the problem. Basically that method is meant to be called once, like in initialize cell, and not overtime the cell is reused. For cases where we are attaching the gesture every time a cell is being reused, we should be using RegisterTemporaryGestures:

if (this.AllowEditing && colDef.Editable)
                    {
                        var tapGesture = new UITapGestureRecognizer(this, new MonoTouch.ObjCRuntime.Selector("HandleEdit:"))
                        {
                            NumberOfTapsRequired = 1
                        };

                        cell.RegisterTemporaryGestures(new NSObject[] { tapGesture });


                    }

Now, i have no idea if thats the cause, ( i actually doubt it is), but its definitely worth fixing, as it could lead to issues down the road.

Steve,

no, did not help - problem is still there.

look at the attached video once more.

All I do is edit mode, dismiss keyboard, fast scroll (in a multiple cycles) and then it gets stuck. I need at least 5 clicks to get it into edit mode.

As  mentioned I had similar problem in my code handling edit on my own w/o use of column definition editor, seems with editor problem is the same.

on a video you can see with in a minute I got stuck twice.

Thank you

Mark

Hey Mark, 

So i realized one other thing. When you dismiss the keyboard, we're listening to the delegate on the text editor, calling endEditing() on the DatasourceHelper. But again, that isn't resolving your column properly, b/c we're bypassing the normal column definitions. 

However, what we should be doing, is overriding EndEditing, and handling things there ourselves: 

 public override void DidEndDisplayingCell(IGGridView gridView, IGGridViewCell cell, IGCellPath path)
            {
                if (cell == _editCell)
                {
                    this.EndEditing ();
                }
            }

            public override void EndEditing ()
            {
                if (_editCell != null) 
                {
                    IGCellPath normPath = this.NormalizePath(_editCell.Path);

                    var colDef = this.ColumnDefinitions.GetItem<NSObject>(normPath.RowIndex) as IGGridViewColumnDefinition;
                    colDef.RemoveEditor(_editCell.GridView, _editCell.Path, this, false, false);
                    _editCell = null;
                }
            }

I noticed that when you i collapsed the keyboard, and clicked on another cell, the last edit mode cell was still in edit mode, and it would transition. This should hopefully fix that. Can you try it out and let me know?

Thanks!
