Gets or sets whether the popup window is modal.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web


public virtual bool Modal { get; set; }

Property Value

Type Default Description
Boolean false

true if the popup window is modal; otherwise, false.


A modal popup window retains input focus while open. The user cannot switch windows until the popup window is closed.


When enabling the modal mode, make sure that the ASPxPopupControl.CloseAction property is set properly. It’s necessary to set the ASPxPopupControl.CloseAction property to the CloseAction.CloseButton value, to prevent the popup window from being closed by an outer mouse click (which is a closing action set by default).
