Disabling a button programmatically does not function properly in IE when it is greyed out

On one of my web pages, there are two drop-down lists that interact in the following way:

  1. When something is selected from list 1,
  2. list 2 becomes enabled.
  3. After selecting an item from list 2,
  4. a button is then enabled.

I have been using autopostback on the drop-down lists to achieve this behavior. Below is the code snippet I am currently using to toggle the button's appearance:

if (ddlAvailablePrograms.SelectedValue != string.Empty)
{
     careerInfoLearnMoreSubmit.Enabled = true;
     careerInfoLearnMoreSubmit.Style.Remove("opacity");
     careerInfoLearnMoreSubmit.Style.Add("opacity", "1.0;");
}
else
{
     careerInfoLearnMoreSubmit.Enabled = false;
     careerInfoLearnMoreSubmit.Style.Remove("opacity");
     careerInfoLearnMoreSubmit.Style.Add("opacity", "0.5;");
}

This method works perfectly fine in Firefox. However, I am facing an issue in Internet Explorer where selecting an item in the first drop-down list causes the button to lose its greyed-out styling.

If anyone has any suggestions on how to address this problem specifically in IE, I would greatly appreciate it.

Thank you,

Answer №1

It is a well-known fact that the opacity CSS style presents challenges when it comes to Internet Explorer.

To tackle this issue, consider incorporating the following code snippet into your CSS stylesheet instead of using an inline style:

.opaque {
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)"; 
    filter: alpha(opacity=50);                  
}

Make sure to maintain the exact ordering as shown above.

This method is demonstrated and utilized in the following resource: http://www.quirksmode.org/css/opacity.html

Additionally, some suggest leveraging jQuery to implement opacity changes as it can effectively handle various cross-browser compatibility issues. Have you considered exploring this option?
