I was running a basic LINQ 2 SQL statement:
From role In db.user_role _
Where role.USER_ID = Session("user_id") Select role
when I encountered following error message:
Method ‘System.Object CompareObjectEqual(System.Object, System.Object, Boolean)’ has no supported translation to SQL.
After a little research I found the solution.

Infragistics WebDataMenu is a light-weight highly responsive menu control with rich server and clinet side model. I was using it to display context menu on right mouse click. The code is pretty simple:
function onMouseClick(oEvent) {
if (oEvent.button == 2) { //right mouse button clicked
var menu = $find("xwdmMyMenu");
menu.showAt(null,null, oEvent);
}
}
It checks whether the right mouse button was clicked (line 2) then locates the menu object and shows it using showAt method (which accepts 3 parameters, either X and Y client coordinates, or event object from which it derives coordinates of the mouse click).
It’s all well and good, but the problem is – menu always shows down from the location of the mouse click. And if the click is at the bottom of the screen – menu gets cut off:
I needed to make menu expand UP and couldn’t find a build-in property or method that would change this behaviour (GroupSettings.ExpandDirection property had no effect). Time for a little hack. Continue reading 'Infragistics WebDataMenu: Expanding context menu UP'»
I was using a pretty standard line of JavaScript code to set dimentions of an HTML element, something like:
oDiv.style.height = iWindowHeight/2 - 50;
It was working fine in IE, but had no effect whatsoever in Firefox.
Turned out all that was needed – to add ‘px’ to that line:
oDiv.style.height = iWindowHeight/2 - 50 + 'px';
and it works fine in both browsers.
If you’re trying to use ASP.NET AJAX features (like Script Manager or Update Panel) in your ASP.NET 3.x website and getting “ASP.NET AJAX client-side framework failed to load” error, chances are your Web.config file is missing required sections. Fastest way to correct this is to create a new ASP.NET website in Visual Studio (you can delete it afterwards) and copy missing sections from the new web.config to the one in your web site.
Update: As churawut pointed out missing .AXD mapping in IIS configuration is another common source of this error (often this is done as security hardening on the IIS). I encountered it while researching missing images in ASP.NET charts, and found out that underlying reason was missing/corrupt .AXD mapping in IIS.
