Steve,

Sorry, but after looking into SingleRowDatasourcehelper i am still not clear how it is going to help me.

I have 16 rows, each row has unique cells and dynamic number of columns. Today my IGGridViewDataSourceHelper returns numberofColumns, numberofFixedColumns etc.....

From rowid I know which cell to create but now I want to use editable cells feature (available in  ColumnDefinitions) and am not sure how to achieve similar functionality since I do not have named column names - each row contains the same column.

any suggestion

thank you

mark

Steve,

yeah, it is inconsistent. Happening after FAST scroll most of the time.

I recorded the video using Jing (great free software) , if you see me staying on some cell for a few seconds and nothing changing - it's me trying to click w/o success.

To view just drop unzipped file into Chrome browser.

Thank you

Mark

steve,

by no means i want to rush you, just was wondering if you were able to see the recording and reproduce on your side the behavior I am seeing

thank you

mark

Hey Mark, 

Sorry for the delay!

I wasn't able to reproduce that exact issue in your video. I did get a crash though in some cases. And thats related to the fact that we're not setting the _edtiCell to null in one case: 

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

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

Adding that should avoid the crash. Perhaps thats related to the issue you're running into. However, i'm not sure why it wouldn't just be crashing for you then.

steve,

it is not null.

by hitting keyboard dismiss buton on  a keyboard and then scrolling right or left fast 50% of the time the next single click is not taking cell into edit mode and sometimes I need to click 5 times (dbl clicking at at time) to get cell into edit mode. weird behaviors. on attached video you can see that very quickly i get stuck on P8 cell. clicking may be 10 times at various points before getting cell into edit mode

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!

Steve,

Got the fix - all good.

Thank you again

Mark

Yes, as soon as we get it fixed, we will send you a private build. 

Thanks again for your patience, and creating that sample. 

Hope you have a good weekend as well!

-SteveZ

that is a great news. many days trying to resolve thinking it is to do with cells and editors until last night when I decided to add sliderview. 

thank you very much

hopefully once it is fixed I will be able to get a private build again

have a great weekend

Ok i figured it out. 

Looks like there is a bug in the tab view, where floating hit targets for the tabs aren't getting positioned correctly when you rotate. 

My developer that works on the tab view is out today, but i'll have him look into it first thing next week. 

I was able to figure out what was happening by looping through all the the views in the hierarchy and apply a border so that i could see if anything rogue was floating around. 

    this.applyBorderToAllSubViews (this.View);


        private void applyBorderToAllSubViews(UIView view)
        {
            foreach (UIView v in view.Subviews) {
                this.applyBorderToAllSubViews (v);
                v.Layer.BorderColor = UIColor.Red.CGColor;
                v.Layer.BorderWidth = 1;
            }
        }

Hey Mark, 

Thanks for the sample. I was finally able to reproduce it!!

Unfortunately, right now i have no idea whats the issue... Its really weird. There is basically a dead spot that occurs, and you can't even scroll on that area. Something is eating the event, but if you click slightly to the left, or slightly to the right of it, it works fine... 

I wish Xamarin had a visual inspector that I could use to debug like Xcode does, then i could see if there is some rogue invisible element floating there. (Although i kind of doubt it, since it eventually goes away...)

Anyways, this may take some time to debug, but i just wanted to let you know that i am looking into it.
