Thank you for responding rapidly Stephen.

UISwitch is what I was trying to say !

I am building a tablet app with Xamarin.iOS using C#. Right now the column definition is a standard one displaying 0 or 1.

Looking forward to your sample - the custom column definition code would be more than enough.

Thank you in advance.

Ok, great :)

I've attached a sample that shows an example of a "checkbox" column. 

    _dsh.ColumnDefinitions.Add(new CheckboxColumn("boolProp"));

Then Create a column, that is in charge of passing around your custom cell: 

public class CheckboxColumn : IGGridViewColumnDefinition
    {
        public CheckboxColumn(String key) : base(key)
        {

        }

        public override IGGridViewCell CreateCell(IGGridView gridView, IGCellPath path, IGGridViewDataSourceHelper dataSource)
        {
            CheckboxCell cell = (CheckboxCell)gridView.DequeueReusableCell("cb");
            if (cell == null)
            {
                cell = new CheckboxCell("cb");
            }

            bool val = ((NSNumber)dataSource.ResolveDataValueForCell(path)).BoolValue;
            cell.UpdateValue(val);

            return cell;
        }
    }

Then create your custom cell : 

public class CheckboxCell : IGGridViewCell
    {
        UISwitch _switch;
        public CheckboxCell(String identifier) : base(identifier)
        {
            _switch = new UISwitch();
            this.AddSubview(_switch);
        }

        public override void SetupSize(CoreGraphics.CGSize size)
        {
            base.SetupSize(size);

            _switch.Frame = new CoreGraphics.CGRect(0, 0, size.Width, size.Height);

        }

        public void UpdateValue(bool val)
        {
            _switch.On = val;
        }
    }

Hope this helps!

Dear Stephen,

Is it possible to post a swift example?

Works like a charm. Thanks.
