in advance thank you

If I have deciphered your post correctly, you can show the ModalDialog but it doesn't "color" the rest of the page, therefore making the popup non-Modal?

If this is the case, then you need set the BackgroundCssClass attribute of the ModalPopupExtender to a valid CSS class.

I normally use this...

 .ModalBackground
 {
      background-color:Gray;

      filter:alpha(opacity=50);
      -moz-opacity:0.5;
      -khtml-opacity: 0.5;
       opacity: 0.5;
 }

 <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server" BackgroundCssClass="ModalBackground" [... the rest of the attributes....] />
