How to apply dynamic text to the gridview empty data template in ASP.NET

In this article, i am going to give some overview on how to set text in EmptyDataTemplate Dynamically. First We have to define a label in EmptyDataTemplate and call the specified function in its Text Property. After that, just declare the specified function at anywhere in aspx.cs page. Something Like this:-
aspx page

  <asp:GridView ID="gvOrders" runat="server" AutoGenerateColumns="False">
     <Columns>
         <asp:TemplateField HeaderText="Data Items">
             <ItemTemplate>
                 <%# Container.DataItemIndex %>
             </ItemTemplate>
         </asp:TemplateField>
         <asp:TemplateField HeaderText="Price">
             <ItemTemplate>
                 <asp:Label ID="lblPrice" runat="server" Text='<%# Eval("price") %>' />
             </ItemTemplate>
         </asp:TemplateField>
         <asp:TemplateField HeaderText="Quantity">
             <ItemTemplate>
                 <asp:Label ID="lblQuantity" runat="server" Text='<%# Eval("quantity") %>' />
             </ItemTemplate>
         </asp:TemplateField>
     </Columns>
     <EmptyDataTemplate>
         <asp:Label ID="lblEmptyText" runat="server" Text='<%#BindEmptyText() %>' />
     </EmptyDataTemplate>
  </asp:GridView>

aspx.cs page

    protected string BindEmptyText()
    {
        if (gvOrders.Rows.Count == 0)
        {
            return "No order was made!!"; // if no row found
        }
        return string.Empty; // if any row found
    }
