Session keeps timing out when debugging iis7

I found out why this is happening. In IIS7 on the Application Pool, there are ping settings that will kill a session if it gets not response. This is great for production as it keeps iis running slim but when debugging in Visual Studio and stopping on a breakpoint that is nasty.

I found an article that explains how to disable the ping or extend the timeout period.

Do NOT use Response.Close unless you really need to

I found out the hard way with a bug I was getting. A JSON call was truncating on me and it turns out a Response.Close was intermittantly removing the last character.

component art menu control. Object reference not set to an instance of object at ComponentArt.Web.UI.BaseNavigator.LoadClientXmlNodeProperties

If you get the following error odds are the menu or submenu text fields is not filled in properly.
The odd thing is it only happens on postback.

The server can't fulfill your request. (Error loading client data:

The 'SelectedIndex' and 'SelectedValue' attributes are mutually exclusive

If you get this error its because you are setting the selectedvalue and selected index of a control in the same event. The following article explains it further.

Telerik controls and IE 8 Beta

I came across this thread in case you are seeing breaks in some telerik controls in IE 8 as well.

Some of the comments mention using a compatability meta tag and placing it as the first meta tag:

< meta equiv="X-UA-Compatible" content="IE=7">
