Datasource + .NET controls

Question

I am using OpenEdge 10.2B and OpenEdge Architect and I did the following steps:

• created a form.
• added a .NET grid control and a button that I named gridCustomer and btnProcess.

• created a temp table like this:

  DEFINE TEMP-TABLE ttCustomer
  FIELD CustNo AS CHARACTER FIELD Name AS CHARACTER FIELD City AS CHARACTER.

• added an event ButtonClick event.

In this event, I am able to populate the temp-table but I could not assign it as a datasource like this:

ASSIGN gridCustomer:DataSource = THIS-OBJECT:ttCustomer.

I get the error message : could not locate element ttCustomer in class.

Is there an example or a documentation somewhere about how to populate a datasource of a .NET control?

Thank you very much! Sebastien

You have to assign a BindingSource object that points to a buffer, query or prodataset handle:

gridCustomer:DataSource = new Progress.Data.BindingSource(BUFFER ttCustomer:HANDLE).

Look for Progress.Data.BindingSource class in the OpenEdge Help for a detailed explanation.
