Progress Event (LoadDocumentAsyncOptions)

Summary

Event that occurs one or more times while the factory is loading the document to indicate the current progress.

Syntax

C++

public event EventHandler<Leadtools.Documents.LoadAsyncProgressEventArgs> Progress

Public Event Progress As EventHandler(Of Leadtools.Documents.LoadAsyncProgressEventArgs)

public:  
   event EventHandler<Leadtools::Documents::LoadAsyncProgressEventArgs^>^ Progress

Remarks

Progress will occur one or more times while the document is being loaded and it can be used to show a progress bar indicator for the user (and optionally, support for aborting the load). Progress uses the LoadAsyncProgressEventArgs event data class that is populated with the following for each "chunk":

Member	Value
System.ComponentModel.ProgressChangedEventArgs.ProgressPercentage	Current progress percentage. This value goes from 0 to 100..
System.ComponentModel.ProgressChangedEventArgs.UserState	The same value originally set by the user in LoadDocumentAsyncOptions.UserState.
Uri	The location of the document being loaded. This is the uri value passed to LoadFromUriAsync
BytesReceived	Number of bytes received during this chunk of the operation.
TotalBytesToReceive	Total number of bytes received so far for the whole load operation.
IsCancelPending	Can be used to abort the load operation.
