ObjectDataSource Update method and StronglyTyped data tables

P: n/a
Hi,

I am truing to find a pattern for my Business Logic Layer to be able to work
fine win ObjectDataSource's Update method.
The challenge is ObjectDataSource is not able to work with an update method
that accepts a strongly typed data table as parameters. We have to have an
update method with all data table's columns as its parameter. Like what we
have here: http://asp.net/learn/data-access/tutorial-16-cs.aspx

I am trying to avoid listing all columns as Update method's parameters. Is
there any way to use the actual strongly type data table as the parameter
for ObjectDataSource's update method?

Any help would be appreciated,
Max

Hi Max,

Regarding on the ASP.NET ObjectDataSource and the update method, it will
always require the following parameters pattern:

** a parameter list which represent all the necessary fields of a data
record(or a custom object)

** a custom class instance(whose properties can be mapping to database
record fields)

This reason why ObjectDataSource limit this is that DataSource control is
designed to work together with those complex databound controls, and for
those controls(such as GridView, DataGrid, DataList), its updating model is
one-record(row) per updating time(not batch updating). If you use DataTable
as parameter, that means you want to do batch update which doesn't match
those template databound control's update model. For such scenario, I
think it would be more flexible that you write the udpating code logic your
self so as to batch update multiple records.

Sincerely,

Steven Cheng
