I have created a panel in my page view (tour.aspx file).
Now I want to access it in my class file (add\_tour.cs file).

This is my panel:

```
<asp:Panel ID="itinerary_panel" runat="server"></asp:Panel>

```

This is my code behind `tour.aspx` file:

```
add_tour tour_obj = new add_tour();
int days_count = 2;
tour_obj.textbox_generator(days_count);

```

And this code is in `add_tour.cs` file:

```
public void textbox_generator(int days_count)
{

}

```

Now how to access the panel from aspx file?
Please help.
