SyncGridCellNumericRenderer not working in 16.1.0.37

Hi, 

I use the version 16.1.0.37. 

I use the specific renderer to change the keyboard for a SfEntry which contains a double value.

[assembly: ExportRenderer(typeof(SfEntry), typeof(SyncGridCellNumericRenderer))]
namespace Android.Controls.Renderer
{
    public class SyncGridCellNumericRenderer : EntryRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
        {
            base.OnElementChanged(e);
            if (e.OldElement == null)
            {
                var value = e.NewElement.Text;
                if (!string.IsNullOrEmpty(value))
                {
                    double valeur = 0;
                    if (double.TryParse(value, NumberStyles.Any, CultureInfo.InvariantCulture, out valeur))
                    {
                        this.Control.KeyListener = new CustomNumericKeyListener();
                    }
                }
                var nativeEditText = (global::Android.Widget.EditText)Control;
                nativeEditText.SetSelectAllOnFocus(true);
            }
        }
    }
}


On previous version, it works very well. 
Now the class is never called.

I try to use the new renderer (GridCellTextViewRenderer), but i can't specify a keyboard.

I don't use GridNumericColumn becase when I entered a '.' (dot) nothing happened and when I entered a ',' (comma) 
I have an exception

new GridNumericColumn(){
AllowNullValue = true,
CultureInfo = new System.Globalization.CultureInfo("fr-FR"),
NumberDecimalDigits = 2,
NumberDecimalSeparator = ","
}

Sorry for the inconvenienced caused.   
  
We have analyzed the reported query for SyncGridCellNumericRenderer is not working in 16.1.0.37. We have prepared a sample for the reported query to validate the same from our side and we have checked in the 16.2.0.32 version where also the SyncGridCellNumericRenderer is does not calls in the sample. We have attached the tested sample and you can download from the following link.  
  
  
Please modify the attached sample to reproduce the reported issue from your side which will be helpful for us to validate and provide you the solution at earlier.

Thanks. 

With the last version, I don't have the previous exception and it works. 

But I use the specific code to EndEdit the cell when the key 'Enter' is pressed : 

private async void DataGrid_CurrentCellBeginEdit(object sender, GridCurrentCellBeginEditEventArgs e)
        {
            {
                await Task.Delay(100);
                if (((column as IElement).Element as ContentView).Content is SfNumericTextBox)
                {
                    var c = ((column as IElement).Element as ContentView).Content as SfNumericTextBox;
                    c.ValueChangeMode = ValueChangeMode.OnLostFocus;
                    c.ValueChanged += Entry_Completed;
                 }
             }
}

private async void Entry_Completed(object sender, EventArgs e)
        {
            try
            {
                dataGrid.EndEdit();
}
            catch (Exception x)
            {}
}

In the catch I have the following exception : 

System.NullReferenceException: Object reference not set to an instance of an object.
  at Syncfusion.SfDataGrid.XForms.GridEditingController.EndEdit (System.Boolean canCommit, System.Boolean cancelEdit) [0x0031c] in <a03bd74b78e84dd4875c47258a289b57>:0 
  at Syncfusion.SfDataGrid.XForms.SfDataGrid.EndEdit () [0x00006] in <a03bd74b78e84dd4875c47258a289b57>:0 
  at Views.Views.Saisie.Saisie+<Entry_Completed>d__7.MoveNext () [0x00024] in  


And after I have this uncatched exception. 

Unhandled Exception:
System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'Com.Syncfusion.Numerictextbox.SfNumericTextBox'.

What is the solution? 
Come back to GridTextColumn?
