VB.NET Update, Delete Gridview with ObjectDataSource

I am trying to figure out how to update a gridview on my webpage which is bound to an ObjectDataSource.  I have loaded the gridview based on a parameter to filter the results but I cannot figure out how to get the UPDATE and DELETE commands to work.  When I go through the configure data source wizard for the ObjectDataSource I see where I can specify a method for UPDATE and DELETE.  I have created UPDATE and DELETE methods in the dataset designer using both SQL and stored procedure but I get errors.

Can anyone give me some direction as to what I should be doing differently or what I need to look at to get the methods to work?

Example 1:

I selected one of the auto-generated UPDATE methods that were created with the dataset.  In the wizard where I have the option to choose an update method it is listed as "Update(tablenameDateTable), returns Int32".  Using this method I get the error "Could not find a property named 'Column1' on the type specified by the DataObjectTypeName property in ObjectDataSource 'odsTableName'.   Column1 is the first column listed in the gridview that I want to update in the table.

Example 2:

I selected "Update(DataRow dataRow) returns Int32" for the method and the error message I get from that one is "No parameterless constructor defined for this object".

Should I be doing something in the code behind file to update the gridview?  It looks like this functionality is built-in to visual studio.

I also tried using an update method that I created in the dataset (called UpdateMethod).

UPDATE Table SET var1 = @var1, var2 = @var2 WHERE ID = @ID

When I use this Update method in the ObjectDataSource I get an error "ObjectDataSource 'ods1' could not find a non-generic method 'UpdateMethod' that has parameters: var1, var2, original_ID.

I can't seem to pass the parameters of the gridview row to the update method.

I found that my solution was that I needed to use the parameter @original_ID rather than just @ID.  Visual Studio apparently was looking for @original_ID.
