Q2 2011 Service Pack 1 (Version 2011.2.915)
Breaking change: Now all HTML 5 compliant browsers, which support the File API interface (FireFox 4.0+, Chrome latest, Safari 5.0+), use the File API module.
Reason: Numerous of problems with the Silverlight/Flash plugins in browsers different than IE. The FileAPI module provides the same features as Flash/Silverlight with one exception. It is not yet possible to display extensions filter within the select file dialog. However, this functionality is part of the input[type='file'] specification and it is about time that the browsers implement it.
Problem: Using the Flash module in IE6/7/8 debug information is displayed into the Developers Bar JavaScript console.
Reason: Non commented console.log invocation within the ActionScript code.
Solution: The problem will be resolved in the upcoming Latest internal build.
Q2 2010 (Version 2011.2.713)
Problem: RadAsyncUpload sometimes fail to upload the files to the target folder.
Reason: The temporary files, which RadAsyncUpload uses internally to save the uploaded files to the target folder, are being deleted too early, hence leaving the upload without files to save.
Solution: We have fixed the problem for the latest internal build (version 2010.2.722+). More information on how to obtain the latest internal build can be found here.
Alternatively, you can do the following:
Step 1: Add an ashx handler to your app. Inside, use the following code:
<%@ WebHandler Language=
"C#"
Class=
"CustomHandler"
%>
using
System;
using
System.Web;
using
Telerik.Web.UI;
public
class
CustomHandler : AsyncUploadHandler {
protected
override
IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration configuration,
string
tempFileName)
{
configuration.TimeToLive = TimeSpan.FromHours(4);
return
base
.Process(file, context, configuration, tempFileName);
}
}
Then, set the HttpHandlerUrl property of RadAsyncUpload to point to that handler. Like this:
<
telerik:RadAsyncUpload
runat
=
"server"
ID
=
"RadAsyncUpload1"
HttpHandlerUrl
=
"~/CustomHandler.ashx"
TargetFolder
=
"~/Documents"
>
</
telerik:RadAsyncUpload
>
