How can I make my Modal Popup Extender Modal? (Disable background)

Question

I added a simple ajax modal popup extender to my asp.net application. It appears and functions correctly, however unlike the sample on the ajax toolkit website, it does not disable/dim the rest of the page. What do I have to do to achieve this effect? ``` ```

Accepted Answer

You should write an appropriate style in "modalBackground" css class. Appropriate property was already set in you code:

```
BackgroundCssClass="modalBackground" 
```

Here is listing of this class from example page:

```
.modalBackground 
{
    background-color:Gray;
    opacity:0.7;
}
```
