Showing something when loading data

[THL]

Hi,

I have a .NET web page which loads data into several datalists and datagrid on the Page_Load event. Since the loading time is quite long and it looks not responsing in the web browser, so I want to some a animated GIF indicating the web page is not idle.

I set the VISIBLE property of the GIF to TRUE at the very beginning section in the Page_Load event and set it back to FALSE at the end of the event. However, when executing in the browser, the GIF is not displayed anyway.

What's wrong with it? Thanks

Codes:
-------
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Image.visible = True

....... loading datalist and datagrid ....

Image.visible = False

End sub

It will not show if you set visible to false at the end of Event.
