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

@Html.DevExpress().Splitter(
settings => {
settings.Name = "splFullScreenMode";
settings.Orientation = Orientation.Vertical;
settings.FullscreenMode = true;
settings.Panes.Add(pane => {
...
}).GetHtml()
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;
}
</style>
