WebPart.IsShared Property

Gets a value that indicates whether a WebPart control is shared, meaning that it is visible to all users of a Web Parts page.

Namespace:  System.Web.UI.WebControls.WebParts
Assembly:  System.Web (in System.Web.dll)

[BrowsableAttribute(false)]
public bool IsShared { get; }

Property Value

Type: System.Boolean
true if the WebPart control has shared user visibility on a Web page; otherwise, false. The default value is false.

A shared Web Parts control is visible to all users of a Web page. The opposite of a shared control is a per-user control, which is user-specific and is visible only to the user who added that control to a page.

If a dynamic control is added while a user is viewing the page in shared personalization scope, the control will be shared. If the control is added while the user is in user personalization scope, the IsShared property value for that control will be false.

For more information about shared and per-user controls, see Web Parts Personalization Overview.

The following code example demonstrates the use of the IsShared property for a custom Web Parts control. This example assumes the use of a custom control, TextDisplayWebPart, created in the Example section of the WebPart class overview.

When you load the Web page in a browser and click the Check Sharing button, the code checks the IsShared property on the TextDisplayWebPart control, and the value of the property is true, because the control is referenced as a static control in the declarative markup of the page.
