To make the DIV tag overlay the existing page, I needed to set the Z-index of the DIV at a higher level then anything else on the page. I soon found that no matter how hard you tried, all DropDownList boxes and List boxes would show through the error dialog.
After some research, I soon found that this is an issue with Internet Explorer and wasn’t much I could do about it. It is because DropDownList boxes and List boxes are considered a windowed component in the browser and regardless the z-index you assign these components or the DIV that contains them, they will always float to the top. This issue is resolved in IE7, but the idea of making all customers upgrade to IE7 was not acceptable.
After adding this code, any click on the page that used an Atlas Update Panel, caused the discreet Unknown Error dialog box. After many attempts to discove what the problem may be, I moved the entire function to script tags with-in the BODY of the page. All worked fine, with no Atlas “Unknown Error”.
In Visual Studio 2005, go to Tools>Options> Text Editor > HTML > Format > Check both:
- “Insert attribute value quotes when typing”
- “Insert attribute value quotes for formatting”
Thank you Steve.
I found another issue using Atlas the other day. I was using Atlas UpdatePanel around a TreeView and had some java-script functions on the page elsewhere. All was going fine Tuesday evening, then Wednesday morning, I started getting a what appeared to be a java-script error message.
When debugging, I was able to confirm that Atlas was working, I could step through my server code and populate the tree, but when execution was back at the browser, I would get this error pop-up “Unknown Error”.
