            ' Logic to sort the resultant list based on sort expression
            If Not ResourceSortExpression Is Nothing AndAlso ResourceSortExpression <> String.Empty Then
                ' From grid, if click on sort link then below logic applied
                Dim param = Expression.Parameter(GetType(lk_xyzEnitty), CStr(ResourceSortExpression))
                Dim sortExpression = Expression.Lambda(Of Func(Of lk_xyzEnitty, Object))(Expression.Convert(Expression.Property(param, ResourceSortExpression), GetType(Object)), param)

                If ResourceSortDirection = "ASC" Then
                    gridViewControl.DataSource = q.ToList().AsQueryable().OrderBy(sortExpression)

                    gridViewControl.DataSource = q.ToList().AsQueryable().OrderByDescending(sortExpression)
