Namespace: DevExpress.Web

Assembly: DevExpress.Web.v22.1.dll


public bool FullscreenMode { get; set; }

Property Value

Type Default Description


true, to enable full-screen mode; otherwise, false.


To enable full-screen mode for an ASPxSplitter control, set the FullscreenMode property to true. In this case, the control fills the entire page and can be resized together with the browser window.

Note that when you set the FullscreenMode property to true, the Height and Width properties are set to a value of 100%. Specific style settings are applied to page elements (such as HTML, BODY, FORM) on the client side, to disable default page padding, margin and scrolling settings and set the height of these container elements to 100%.

<style type="text/css">
     html, body, form {
          height: 100%;
          margin: 0;
          padding: 0;
          overflow: hidden;


The ASPxSplitter control must be a root WebForm element when it works in the full-screen mode. It can be placed in a simple containers (e.g. div or form elements) only. Other controls cannot be placed at the same level.
