AllowWebBrowserDrop Property

WebBrowser.AllowWebBrowserDrop Property

Gets or sets a value indicating whether the WebBrowser control navigates to documents that are dropped onto it.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public bool AllowWebBrowserDrop { get; set; }

Property Value

Type: System.Boolean
true if the control accepts documents that are dropped onto it; otherwise, false. The default is true.


This WebBrowser instance is no longer valid.


A reference to an implementation of the IWebBrowser2 interface could not be retrieved from the underlying ActiveX WebBrowser control.

By default, the WebBrowser control automatically navigates to documents that are dropped onto it. This behavior is useful when you use the control as a generic browser. If you use the control to display content designed specifically for your application, such as HTML-based user assistance, set the AllowWebBrowserDrop property to false to prevent the display of other content. This is particularly useful when you want to conceal the fact that you are using the WebBrowser control, for example to create a user interface that seamlessly combines Web-based controls with Windows Forms controls.

You can disable other standard browser features by setting the WebBrowserShortcutsEnabled and IsWebBrowserContextMenuEnabled properties to false.


This property is not related to the Control.AllowDrop property and does not cause drag-and-drop events such as the Control.DragDrop event to occur for the control.

The following code example demonstrates how to use the AllowWebBrowserDrop property.

webBrowser1.AllowWebBrowserDrop = false;
