non-generic method

[Guest]

I have a detailsview connected to a dataset on a aspx page. When I run the
page and try to do an update on the data I receive the following error,

ObjectDataSource 'UserInstall2' could not find a non-generic method 'Update'
list of all fields in dataset.

Since all fields are in my detailsview, what does this mean?

It expects your object "UserInstall2" to have a method called 'update' that
it can use to update the object when the user saves changes.
