Remarks

If the uploaded file exceeds the MaxFileSize property’s value, an error text specified by the UploadControlValidationSettings.MaxFileSizeErrorText property is displayed within the ASPxUploadControl‘s specific error frame. The uploaded file’s validation is considered to have failed in this case (this means that the ASPxUploadControl.IsValid, FileUploadCompleteEventArgs.IsValid and ASPxClientUploadControlFileUploadCompleteEventArgs.isValid properties are set to false).

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.
