How to Create a Custom DevExpress Report Control

Report Control Development Steps

To create a new report control, do the following:

1. Choose a base class. If you cannot find a suitable control to derive from, inherit a component from the XRControl class.

2. Create the component's object model. Specify a set of properties and related attributes that determine how properties are serialized and displayed in the Property grid.

3. Create component designers for Visual Studio and the End User Designer. Designers determine the component's appearance and behavior at design time. Add attributes as necessary.

4. Choose the base class for the component's “brick” - such as the brick that the base class creates. However, if the component inherits from the XRControl class, there are two options - select VisualBrick as the brick's base class if you require a simple brick or PanelBrick if you need a container.

5. Specify how the component creates its "brick" and map the component's properties to the brick's characteristics.

6. Implement the BrickExporter class to render the "brick". Override the methods used for drawing and export.
