I have an animated gif in an image control:
Me.ImageProgress1.Visible = False

I want that when the User click on a given button to execute a long
task
Me.ImageProgress1 become visible until the task on the server is
finished.
I call the task this way:

Protected Sub ButtonSomeLongTast_Click(ByVal sender As Object, ByVal
e As System.EventArgs) Handles ButtonSomeLongTast.Click

ExecuteLongTask()

End Sub

I think I am dumb as I can't figure out how to do this simple thing!
Thanks for any help!

What you can also do is add some javascipt to the onclick() method of
the button to change the visibility of the image.
 
I tried but it does not work. See a blank page.
Can anyone show a simple working example?

How about some more of the code you're writing?

Hi Ray, Do you know how to do it?

I have

Protected Sub ButtonSomeLongTast_Click(ByVal sender As Object, ByVal
e As System.EventArgs) Handles ButtonSomeLongTast.Click

ExecuteLongTask()

End Sub

then I grabbed this from internet:

<script language="javascript">
function toggle(e) {
if (e.style.display == "none") {
e.style.display = "";
} else {
e.style.display = "none";
}
}
</script>

I placed after
<title></title>

Also I placed
<body onload="toggle(progress)">

Then under onclick() event of button1 I placed: = "toggle(progress)"

where progress is a DIV which contains the image with the GIF

<div id="progress"> MyAnimatedImage </div>


No luck!!
I am a beginner and I am probably missing something basic.
Some simple working example in code would be great.
