  • RadUpload

    RadUpload is a control for single and multi-file uploads with integrated file validation and more.

    The RadUpload appearance can be customized using the ControlObjectsVisibility property of type ControlObjectsVisibility. The ControlObjectsVisibility enumeration contains the following members:

    • None - displays only the file input fields
    • CheckBoxes - displays checkboxes in front of the file input fields. Used in conjunction with the Delete (Selected) button and the DeleteSelectedButton value of ControlObjectsVisibility
    • RemoveButtons - displays Remove buttons on the right of the file input fields
    • ClearButtons - displays Clear buttons on the right of the file input fields
    • AddButton - displays an Add button below the file input fields
    • DeleteSelectedButton - displays a Delete button below the file input fields - used in conjunction with the CheckBoxes value
    • Default - a combination of CheckBoxes, RemoveButtons, AddButton and DeleteSelectedButton values
    • All - a combination of all the members

    The ControlObjectsVisibility property can receive any combination of these flags, e.g.:

    Radupload1.ControlObjectsVisibility = ControlObjectsVisibility.RemoveButtons | ControlObjectsVisibility.ClearButtons

    RadUpload exposes two properties to control the number of file inputs:

    • InitialFileInputsCount - the file inputs count which will be available at startup. The default value is 1.
    • MaxFileInputsCount - limit the maximum number of file inputs which can be added to a RadUpload instance.
