The largest allowed combined file size for upload in this example is 100MB. This is specified by the
maxRequestLength="102400" set in Web.config file. If you attempt to upload files with total size greater that 100MB
you will get "Page Not Found" error. For more information about uploading large files visit the help article
Using TargetFolder
In order to use automatic file saving, the TargetFolder
property must be set to an existing virtual folder. This virtual path will be
internally resolved to a physical path by calling the Server.MapPath() method.
The TargetPhysicalFolder
property is provided for the cases where the files must be automatically saved
to a physical path. If you set both TargetFolder and TargetPhysicalFolder properties,
RadUpload will use TargetPhysicalFolder.
When one of the properties above was set, the uploaded files will be validated
if the validation has been enabled. Then the valid files will be saved in the specified
location with their original names from the client computer. If a file with the same name
already exists on the server it may be overwritten, depending the value of the
OverwriteExistingFiles property.
The FileExists event is fired when one of the TargetFolder or
TargetPhysicalFolder properties was set, the OverwriteExistingFiles
property was set to false and there is already a file with
the same name as the currently uploaded file. You can use this event to save the
existing uploaded files with a different name.
