The best way to solve this problem is to use CSS.
Inside the CSS class you can specify the background property which will take the image for a background or, if the image does not exist, it will use the background color instead. Example:

<style>
.myClass
{
    background:url(Images/top_banner/bck_top_banner.gif) repeat-x top #DDDDDD;
}
</style>

Then you have to assign this class to your link button.
Try this js code, though I am not sure about it:

document.getElementById("LinkButton1").attributes["class"]="myClass";

I would rather use JQuery to handle all javascript.

then it would look like:

$(".myClass").attr("class","myClass");
<pre />

good luck.

Solution 1

It's because you can only specify only one thing to any control
either background image or background color.
1) either create image with background color you want and then assign that image.
2) or create a div tag around button, then give that div tag background color, and then assign a transparent image to button control.
