Known Postback Issue with AJAX Controls

I came across a postback issue while using the CascadingDropDown AJAX control. I had a web page with 3 DropDownList controls. The data for these controls was populated from the CascadingDropDown which would bind the data at runtime. The issue with this is that when data is being bound at runtime, it cannot be validated during postback unless each value is registered with the page.  In most cases, this wouldn’t make sense. So, we have to fall back to turning off EventValidation at an application level in the web.config (attribute is found on the pages element) or at the page level (attribute is added to the page directive). It’s best to turn off the EventValidation at the page level. There is no way to turn this off at the control level unless you are building your own control that does not contain the SupportsEventValidation attribute.

Tip: Set the SelectedValue on a DropDownList that is populated by a CascadingDropDown

When using a DropDownList, you can set the selected item by using the SelectedIndex property. However, if your DropDownList is being populated by the CascadingDropDown control (from the ASP.NET AJAX Control Toolkit), that doesn’t work. Instead, you must use the SelectedValue property on the CascadingDropDown control.

Clearspring Widgets Don't Work on 64-Bit Platform

Unless you are using IE 32-bit, don’t expect the Clearspring widgets to work. Clearspring is one of the leaders in building widgets for social networks and Vista. The reason their widgets do not work is because Flash is not yet supported on 64-bit platforms. By default, the Vista Sidebar on a 64-bit system displays widgets by using IE 64-bit.

The reason for my modifications is that the HTML and CSS settings were very difficult to read. Here is the complete list of changes I’ve made in Tools > Options > Environment > Fonts and Colors:
