Syntaxpublic interface ILoadHandler
public interface class ILoadHandler
The ILoadHandler type exposes the following members.
Methods Name Description OnFrameLoadEndCalled when the browser is done loading a frame. The
Framevalue will never be empty Check the
IsMainmethod to see if this frame is the main frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method will always be called for all frames irrespective of whether the request completes successfully. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang.
OnFrameLoadStartCalled when the browser begins loading a frame. The
Framevalue will never be empty Check the
IsMainmethod to see if this frame is the main frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use
OnLoadingStateChange(IWebBrowser, LoadingStateChangedEventArgs)instead. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang.
OnLoadErrorCalled when the resource load for a navigation fails or is canceled.
ErrorCodeis the error code number,
ErrorTextis the error text and
FailedUrlis the URL that failed to load. See net\base\net_error_list.h for complete descriptions of the error codes. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang.
OnLoadingStateChangeCalled when the loading state has changed. This callback will be executed twice once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure. This method will be called on the CEF UI thread. Blocking this thread will likely cause your UI to become unresponsive and/or hang.
