Drag the control onto a form and customize the control’s settings, or paste the control’s markup in the page’s source code.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    Dim binaryImage As ASPxBinaryImage = New ASPxBinaryImage()
    binaryImage.ID = "BinaryImage"
    Page.Form.Controls.Add(binaryImage)

    binaryImage.Width = 200

Note

DevExpress controls require that you register special modules, handlers, and options in the Web.config file. You can change this file or switch to the Design tab in the Microsoft Visual Studio IDE to automatically update the Web.config file. Note that this information is automatically registered if you use the DevExpress Template Gallery to create a project.

This class inherits its basic functionality from its ancestor. The ASPxBinaryImage.ContentBytes property provides access to the editor’s contents represented by an array of bytes. The ASPxBinaryImage.StoreContentBytesInViewState property allows you to control whether the editor’s content should be stored within the editor’s view state between postbacks.

Note

Use the ASPxImage control to use the URL path to show an image from the server side.
