Example

In this example, the ASPxProgressBar control is used to visualize the progress of a file upload initiated within the ASPxUploadControl. The ASPxClientUploadControl.UploadingProgressChanged client event of the ASPxUploadControl is handled, to supply the ASPxProgressBar control with current progress information. Using the ASPxProgressBar as a separate control, allows placing it at any desired position within the page. The complete sample project is available in the DevExpress Code Central database at E1252.
