Does anyone have any links to some documentation on these its impossible to search for this as I dont know what its called. But in example websites ive seen all of the used and still dont know what they actually mean.

<%= This is the equivelant to Response.Write("foo"); and it is used, mostly, in old classic asp websites. It can still be used in .NET websites, however, there is no real reason to do it since you can place a variables vaule in a label, literal control, etc. (To do this in a .NET website the varaible has to be declared with a scope of public)

From the book Beginning ASP.NET 2.0 and Databases: "DataBinding Expressions <%# ... %> can contain more than just Eval and Bind statements. In fact, they can contain arbitrary code expressions. For example, if a public property on my page is named MyControl.MyProperty, it could be referred to as <%# MyControl .MyProperty %>"

So, to simplify, the <%#...%> designates databinding within a control (GridView, DataList, etc).

hth.
