Question

I was wondering if I can make a button or a div tag only visible/invisible when the user is browsing with IE. I want to achieve that because I have Microsoft JScript runtime error: Access is denied. in IE when the user clicks on a button which triggers hidden asp.net fileupload control.

EDIT:
I have asp button :

<asp:LinkButton ID="btnSavePhoto" runat="server"></asp:LinkButton>

and file upload control with class=”hidden” (dysplay: none;):

<asp:FileUpload ID="uploadPhotoDialog" class="hidden" runat="server"/>

The idea is: when the user is browsing with IE – make fileupload visible and link button hidden.

Answer 1

Use conditional comments :

<!--[if IE]>
<div></div> // this is IE
<![endif]-->

or if not IE

<!--[if !IE]> -->
<div></div> // this is NOT IE
<!-- <![endif]-->

Documentation here

Update

Using your ASP markup do the following :

<!--[if !IE]> -->
    <asp:LinkButton ID="btnSavePhoto" runat="server"></asp:LinkButton>
<!-- <![endif]-->
<!--[if IE]>
    <asp:FileUpload ID="uploadPhotoDialog" runat="server"/>
<!-- <![endif]-->

No need for the class attribute then
