Example

The following sample code demonstrates how to save the file specified within the ASPxUploadControl on the client. Before file saving, the FileUploadCompleteEventArgs.IsValid property is tested to verify whether the file passes the validation criteria defined via the ASPxUploadControl.ValidationSettings property. Note, that in order to compose the ASPxUploadControl.SaveAs method’s parameter value, the HostingEnvironment.MapPath(String) method and ASPxUploadControl.FileName property are used to specify the web application’s Image folder as a location where the file should be saved, and define the file’s name, respectively.
