Please wait message

My page has a button to print reports. When clicked, a new window is displayed with the reports. Since the report takes time to render, I wanted to display a "Please wait" message first.

I placed this on the page load and the "Please wait message" is displayed prior to the report being shown (see Page1 attachment).

VB Code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Response.Write("<DIV><TD><B>Please wait...</B></TD></DIV>")
        Response.Write(Space(256))
        Response.Flush()
        Response.Flush()

However, when the report is shown, the "Please wait" message is still visible (see Page2 attachment). How do I remove this when page is done loading? How do I replace the Please wait message with an image instead?

Thanks

Use javascript for this. The page can start with the <DIV> showing the message. In the ONLOAD event of the body (body tag), hide the div layer.

I actually tried THIS CODE but it really does not give me the desired results.

With this code, it takes a longer time to see the "PLEASE WAIT" message displayed on the page. Then when it does, it's like a blink only then the whole page is rendered basically defeating the purpose of the function.

With the first code, once the page is redirected, I see the "PLEASE WAIT" immediately and then the whole page is displayed in total afterwards.

What about using the same webform rather than displaying another window? Just a suggestion, but you could have your "please wait" message in an asp:panel control which was hidden until the user clicks on your button...
