There is no property with such name in the RadAsyncUpload
control. The property, which sets the expiration time of the files in the Temporary folder is TemporaryFileExpiration
. The property accepts TimeSpan values. The default value is 4 hours. More information regarding the TimeSpan structure can be found here
However I checked our documentation, but there we have a mistake, which we will fix - this property could not be set globally from the web.config(it could be set in the markup of the control or in the code behind). If you need to set this property globally, you can create a feature request in our Ideas and Feedback
portal. There you can track its status, comment and vote for it.
Please excuse us for the inconveniences caused by this.
Do you want to have your say when we set our development plans?
