IUriStreamService Interface

Defines a service which is called to retrieve data from the URI specified in some types of document fields.

Namespace: DevExpress.Office.Services

Assembly: DevExpress.Office.v19.1.Core.dll

Declaration

[ComVisible(true)]
public interface IUriStreamService

Remarks

When a field is updated, the IUriStreamService.GetStream method is called. This method calls the IUriStreamProvider.GetStream methods of registered providers to obtain a stream of image data. Subsequent calls are made until a successful result is obtained. The order of calls is the order in which providers have been registered. By default, there is only one provider - the WebUriStreamProvider that enables you to load an image from the specified URI by performing a web request.

Example

This example demonstrates how to use the IUriStreamService.RegisterProvider method to register a custom data stream provider implementing the IUriStreamProvider interface and make it available to clients of the IUriStreamService service.

private void RegisterUriStreamService(RichEditControl richEditControl) {
    IUriStreamService uriStreamService = richEditControl.GetService<IUriStreamService>();
    uriStreamService.RegisterProvider(new ImageStreamProvider(NorthwindDataProvider.Categories, "Picture"));
}
