Asp:Imagebutton and javascript

[JIM]

Hello,

I've an asp:Imagebutton on my form with the visible property set to false

<asp:Imagebutton ID="tstImage" runat=Server visible=False>

How can I set the visible propery to true using a javascript ?
I tried something like document.GetElementById('ImgTest').visible='true';
but without succes ....

Any idea ?

Many thanks,

KArel

Isn't that an ASP.NET image button? This is Classic ASP. NG replies

You can't. If you're setting the visibility on the control, then that's
being controlled by the codebehind. If it's set to be visible="false" it
won't even be rendered in the HTML.

For what you want, I think you want to place the button in a DIV and then
HIDE the div via javascript when the page loads. That way it's part of the
DOM and you can then do what you want with it via javascript.

You can't. When its visible property is set to false, it is not rendered in
the client, so there is nothing there on which the clientside code can act.

What you have to do is set its visible property to true. That way there will
be an html element in the client DOM on which client-side code can act.
You can set its display style to none in the body onload event. You can set
it to inline or block in whatever event you are thinking of using to set it
to visible.
