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?

can you provide what errors you are receiving ?

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
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.
