Bound Field in Xamarin Form Grid

Hi, I need Bound Field for XFGrid. If i click on any field in my grid the clicked field should change to textbox. I Created my XFGrid through Code.
private void CreateGrid()
{
XFGrid grid = new XFGrid();
grid.SetValue(XFGrid.RowHeightProperty, 30);
ListAdapter adapter = new ListAdapter() { DataSource = Data, AutoGenerateColumns = false };
TextColumnDefinition col1 = new TextColumnDefinition() { Key = "TagNo", ColumnHeaderLabel = "Tag No" };
adapter.ColumnDefinitions.Add(col1);
TextColumnDefinition col2 = new TextColumnDefinition() { Key = "Name", ColumnHeaderLabel = "Name" };
adapter.ColumnDefinitions.Add(col2);
TextColumnDefinition col3 = new TextColumnDefinition() { Key = "Value", ColumnHeaderLabel = "Value" };
adapter.ColumnDefinitions.Add(col3);
TextColumnDefinition col4 = new TextColumnDefinition() { Key = "Date", ColumnHeaderLabel = "Date" };
adapter.ColumnDefinitions.Add(col4);
TextColumnDefinition col5 = new TextColumnDefinition() { Key = "EstAvg", ColumnHeaderLabel = "Est Avg" };
adapter.ColumnDefinitions.Add(col5);
grid.Adapter = adapter;
RunningHrsGrid.Children.Add(grid);
}
Please help me.

Thanks in advance
