RadUpload has been replaced by RadAsyncUpload, Telerik’s next-generation ASP.NET upload component. If you are considering Telerik’s Upload control for new development, check out the documentation of RadAsyncUpload or the control’s product page. If you are already using RadUpload in your projects, you may be interested in reading how easy the transition to RadAsyncUpload is and how you can benefit from it in this blog post. The official support for RadUpload has been discontinued in June 2013 (Q2’13), although it is still be available in the suite. We deeply believe that RadAsyncUpload can better serve your upload needs and we kindly ask you to transition to it to make sure you take advantage of its support and the new features we constantly add to it.
Both RadUpload and RadProgressArea have a Skin property, which you can use to specify a skin. The skin provides a basic look-and-feel to the control.
In addition to the skin, both controls are extremely configurable, letting you specify what child controls appear.
Use the ControlObjectsVisibility property to configure RadUpload to contain only those controls you want.
To affect the appearance of the file input area, you can use the EnableFileInputSkinning property.
Use the Localization property to change the text of the buttons of RadUpload.
Use the dir="rtl" attribute to give the upload a right-to-left orientation
Use the ProgressIndicators and DisplayCancelbutton properties to configure RadProgressArea to contain only those controls you want.
Use the Localization property to change the text of the labels in the progress dialog.
Use progress templates to add your own custom elements or rearrange the existing elements in the progress dialog.
Use the dir="rtl" attribute to give the progress area a right-to-left orientation
