Hello,
I have created a form with grid which contains button and label.So the number or rows and columns vary according to my table.
i haved binded label and button text. now when i click a button i want the data which is binded to that clicked button.
Since number of rows and columns vary i have done this in code behind.Please help

<List> table=new <List>();
protected async override void OnAppearing()
        {
            //data for table is getting using webapi. im not giving that code
            count= table.Count;
            decimal rw = (decimal)table.Count / 3;
            decimal  RowCountRequired = Decimal.Ceiling(rw);
            var maxwidth = Application.Current.MainPage.Width;
            var width = maxwidth / 3;

            for (int currentRow = 0; currentRow < RowCountRequired; currentRow++)
            {
                count = count - ColumnCountRequired;
                for (int currentColumn = 0; currentColumn < ColumnCountRequired; currentColumn++)
                {
                        var label = new Label
                        {

                            HorizontalTextAlignment = TextAlignment.Center,
                            VerticalTextAlignment = TextAlignment.Center
                        };
                        label.SetBinding(Label.TextProperty, nameof(Table_Master.th_tableid));
                        gridLayout.Children.Add(label, currentColumn, currentRow);
                }
            }
            ColumnCountRequired = 3;
            count = table.Count;
            for (int currentRow = 0; currentRow < RowCountRequired; currentRow++)
            {
                gridLayout.RowDefinitions.Add(new RowDefinition { Height = 250});
                gridLayout.VerticalOptions = LayoutOptions.FillAndExpand;
                gridLayout.HorizontalOptions = LayoutOptions.FillAndExpand;
                if (count < 3)
                {
                    ColumnCountRequired =  count;
                } 
                count = count - ColumnCountRequired;
                for (int currentColumn = 0; currentColumn < ColumnCountRequired; currentColumn++)
                {
                    gridLayout.ColumnDefinitions.Add(new ColumnDefinition { Width =width});
                    Button button = new Button
                    {
                        TextColor=Color.White,
                        BackgroundColor = Color.Green,
                        VerticalOptions = LayoutOptions.FillAndExpand,
                        HorizontalOptions = LayoutOptions.FillAndExpand,


                    };

                    button.SetBinding(Label.TextProperty, nameof(Table_Master.th_tablename));
                    button.Clicked += OnButtonClicked;
                    gridLayout.Children.Add(button    , currentColumn, currentRow);

                }

                // reduce the number of columns on the next row to simulate row span       
                // ColumnCountRequired = ColumnCountRequired - 1;

            }

            for (int i=0;i<table.Count; i++)
            {
                gridLayout.Children[i].BindingContext = table[i];
            }

                base.OnAppearing();
        }


private void OnButtonClicked(object sender, EventArgs e)
        {

// if i click row0,col0 th button i want data binded to label o ro0,col0
        }
