Disabled button with a alert is clickable in IE8 (browser compatibility Issue in Asp.net website)

Question

I have disabled a link button and image button(which is inside a link button so that I can show a Alert) and it works fine in Chrome, but when I open it in IE8 the image is dis

Answer 1

Why not merge the ImageButtons purpose with the LinkButton? (or vice versa...)

<asp:LinkButton runat="server" ID="lBtnDeleteUser" OnClick="lBtnDeleteUser_Click"
OnClientClick='return confirm("Are you sure you want to delete this User?")'
style="display: block; background-image: url('Styles/Images/icon_delete.png');
width: widthOficon_delete.pngInPixels; height: heightOficon_delete.pngInPixels;"
ToolTip="Delete" />

Answer 2

<asp:ImageButton ID="Img_del" runat="server" Text="Delete" ImageUrl="Styles/Images/icon_delete.png"
                                AlternateText="Delete" OnClientClick='return confirm("Are you sure you want to delete this item?");' OnClick="imgbtn_UserDeleteClick"/>

I solved it by using pop up in Image button [Learnt a new thing that HTML does not have a disabled attribute for links]
