Solution 1

Your ObjectDataSource1 is not found, reson could be
1) there is some syntax error in your ObjectDataSource1 markup, which is not parsing and not able yo create a control object.
2) you have removed it from your aspx markup page.
3) codebehind class file name in the @Page directive is not propper (check with namespace)

verify your code for solution :)

Solution 2

try by providing fully specified namespace for the class you are using as TypeName..

i.e namespace.namespace.... (.)className

i think you are maybe providing invalid class or the namespace track is not proper to exact class you are trying to point to.
