Rather surprised by the new 'updates are ready' message from Microsoft. Hmmm.

revised updates message from microsoft

Perhaps they know just how much frustration we had on the home pc recently due to their dodgy updates.

Source: Windows Updates Make Me Nervous

This is just a re-statement of a forum thread that discusses the fix, but since gotdotnet is not going to be around very much longer I thought I'd post this little tidbit here as well. Basically, when I upgraded one of my sites to .net 2.0, skmMenu got upgraded right along with it. The only issue was that all of my menus would show up at the far left corner of the screen, and when you try to navigate to them over there they disappear thanks to the menu items between the cursor and the target. I think I only saw this behavior in firefox, but the code fix works in both firefox and IE. I just went thru the .js file and the javascript in the .resx for embedded javascript goodness and placed a 'px' after any integer value. The reason for this is that firefox requires measurement properties be set with appropriate identifiers when it's displaying a structured document. Anyways, here's a reprint of the code:

function skm_mousedOverMenu(menuID,elem,parent,displayedVertically,imageSource){
	skm_stopTick();
	skm_closeSubMenus(elem);
	var childID=elem.id+"-subMenu";  // Display child menu if needed
	if (document.getElementById(childID)!=null){  // make the child menu visible and specify that its position is specified in absolute coordinates
		document.getElementById(childID).style.display='block';
		document.getElementById(childID).style.position='absolute';
		skm_OpenMenuItems = skm_OpenMenuItems.concat(childID);
		if (displayedVertically){ // Set the child menu's left and top attributes according to the menu's offsets
			document.getElementById(childID).style.left=skm_getAscendingLefts(parent)+parent.offsetWidth+'px';
			document.getElementById(childID).style.top=skm_getAscendingTops(elem)+'px';
			var visibleWidth=parseInt(window.outerWidth?window.outerWidth-9:document.body.clientWidth,10+'px');
			if ((parseInt(document.getElementById(childID).offsetLeft,10+'px')+parseInt(document.getElementById(childID).offsetWidth,10+'px'))>visibleWidth) {
				document.getElementById(childID).style.left=visibleWidth-parseInt(document.getElementById(childID).offsetWidth,10+'px');
			}
		}else{  // Set the child menu's left and top attributes according to the menu's offsets
			document.getElementById(childID).style.left=skm_getAscendingLefts(elem)+'px';
			document.getElementById(childID).style.top=skm_getAscendingTops(parent)+parent.offsetHeight+'px';
			if (document.getElementById(childID).offsetWidth<elem.offsetWidth)
				document.getElementById(childID).style.width=elem.offsetWidth+'px';
		}
	}
	if (skm_SelectedMenuStyleInfos[menuID] != null) skm_SelectedMenuStyleInfos[menuID].applyToElement(elem);
	if (skm_highlightTopMenus[menuID]){
		var eId=elem.id+'';
		while (eId.indexOf('-subMenu')>=0){
			eId=eId.substring(0, eId.lastIndexOf('-subMenu'));
			skm_SelectedMenuStyleInfos[menuID].applyToElement(document.getElementById(eId));
		}
	}	
	if (imageSource!=''){
		setimage(elem,imageSource)
	}
}
function skm_shimSetVisibility(makevisible, tableid){
	var tblRef=document.getElementById(tableid);
	var IfrRef=document.getElementById('shim'+tableid);
	if (tblRef!=null && IfrRef!=null){
		if(makevisible){
			IfrRef.style.width=tblRef.offsetWidth+'px';
			IfrRef.style.height=tblRef.offsetHeight+'px';
			IfrRef.style.top=tblRef.style.top+'px';
			IfrRef.style.left=tblRef.style.left+'px';
			IfrRef.style.zIndex=tblRef.style.zIndex-1;
			IfrRef.style.display="block";
		}else{
			IfrRef.style.display="none";
		}
	}
}

These were the only two functions that needed code adjustment. Enjoy.

I read this excellent post from ScottGu and decided to use it with a page that implemented a masterpage. I didn't have to use postbacks in my scenario, but there were links included from the masterpage. The problem is that if you use app-relative paths for your href attributes (ex: <a href="/default.aspx">) the browser (FF 2.0.0.2 and IE 7 anyways) interperets the url with pathinfo differently than a url without. The base url includes the original page (ex: http://localhost:3333/rewriter.aspx/default.aspx). Guess what? The webserver picks up the last .aspx extension, default.aspx, that bad boy doesn't exist, and you get a 404 instead of going to http://localhost:3333/default.aspx.

In the comments, Ian Oxley suggested that you can re-base links in your page/css/other static files using the <base> element in the head of your page. I expanded on it a little, since this behavior is only on one page of my site currently, and added the following code into the Page_Load event of the offending page:

this.Header.Controls.Add(
new LiteralControl("<base href=\"" +
 Request.Url.ToString().Replace(Request.RawUrl, "").Replace(Request.PathInfo, "") + 
"\">"));

Now the base tag works on both the live site and the one that WebDev.WebServer spins up as well.

So I've been able to dig my teeth into some asp.net hacking recently, and I've been wrestling with learning to use SubSonic in the process.

In dealing with the scaffold control I ran into a funny issue: none of the exposed properties on the scaffold control will output any style info of the GridView that the control uses (that I could figure out anyways). I ended up with black text on a black background. :/ Seeing as I have the source, I decided to give the scaffold control's GridView a little class...hello GridViewCssClass property! I set it up just like the EditTable*CssClass properties, just a string property, with similar attributes to the other properties hanging around there:

[Bindable(true)]
[Category("Display")]
[Description("Sets the CSS class used by the gridview.")]
[DefaultValue(ScaffoldCSS.WRAPPER)] //CDF: just to have something to start with.
public string GridViewCssClass {
	get { return _gridViewCssClass; }
	set { _gridViewCssClass = value; }
}

Then, in the CreateGrid method make it actually do something:

        private void CreateGrid()
        {
            Label lblTitle = new Label();
            surroundingPanel.Controls.Add(lblTitle);
            lblTitle.Text = "<h2>" + schema.Name + " Admin</h2>";

            grid.ID = "grid";
	    grid.CssClass = this.GridViewCssClass;

            surroundingPanel.Controls.Add(grid);

            if (!Page.IsPostBack)
            {
                BindGrid(String.Empty);
            }
            //add a column to the grid for editing
        }

And now I can declaratively set the CssClass that the GridView uses to, oh, say, .whitetext :)
