Default Formview with ObjectDataSource

I have come across a problem using the formview with an objectdatasource. When using an object datasource a piece of code like
Button test = (Button)frmvDetails.Controls[0].FindControl("EditButton");
test.Enabled = false;

will generate an error 'Object reference not set to an instance of an object'. Set the formview to reference an SQLDataSource and it is no problem.

I have noticed that if create a new formview and attach it to objectdatasource it will not generate the template code as it does with the SQL code. This is not a problem as it is just a little coding but not being able to reference controls is a problem.

For what I want to do if found the SQLdatasource a problem and the objectdatasource worked really well.

I apologize if this is obvious but did you set up the object data source to be able to update by providing it with an update method on your business object to use for that purpose?

I would guess that the formview you are using might not create the Edit button unless it needed it, and so that led me to my guess. Can you post your code?
