Hello,

I have perhaps discovered a bug with the AjaxManager when an asp:Label is placed inside the UpdatedControls list for an AjaxSetting. I have tried this in IE7, FireFox 2 and Google Chrome.

If you add an AjaxSetting and place an asp:Label as one of the UpdatedControls, when rendering the HTML a <div> tag is placed around the label text, which causes a linebreak to appear in the browser. This may be intended behavior but I'm guessing not?

Cut-and-paste the code sample below and you'll see what I mean. I'm using the Q2 2008 version for .Net 2.0. When viewing this in a browser you'll notice there appears to be a linebreak between "text1" and "text2" -- view the source and you'll notice the extra <div> tag around Label1 which is causing the linebreak to appear.

I actually spent hours troubleshooting this today . . . very bizarre, I finally just started plucking elements from my page to discover why this extra <div> tag was being placed around one of my labels, causing the linebreak to appear in IE, and when I finally got to eliminating the RadAjax controls I discovered it. Your help & input is appreciated!!
