Remarks

Overview

The ObjectDataSource is a data component much like the standard .NET BindingSource component.

The ObjectDataSource component has the following advantages over BindingSource :

It can bind to methods that return a collection of custom objects.
It can bind to parameterized object constructors.
Since it is a cross-platform component, your project does not need the System.Windows.Forms assembly.

Note

The Object Data Source displays only public non-static properties in the Field List.

Refer to the following help topic for examples of use: Use ObjectDataSource.

Data Source for Controls and Components

The following help topics decribe how to use the ObjectDataSource to supply DevExpress controls/components with data:

You can use the Data Source Wizard to bind a component to an Object Data Source. To make a particular assembly, class, or member appear in the Data Source Wizard, use the following attributes: HighlightedAssemblyAttribute, HighlightedClassAttribute, and HighlightedMemberAttribute.

ObjectDataSource Properties

The following properties are used to bind the ObjectDataSource to data.

ObjectDataSource.DataSource
ObjectDataSource.DataMember
ObjectDataSource.Parameters
ObjectDataSource.RebuildResultSchema
Call this method to build the data source schema.
Call the RebuildResultSchema(IEnumerable<IParameter>) overloaded method instead to apply values from external parameters (for instance, report parameters) to the data source parameters before the schema is built.
