Copy

virtual void OnWebPartsConnecting(
	WebPartConnectionsCancelEventArgs^ e
)

Parameters

e
Type: System.Web.UI.WebControls.WebParts::WebPartConnectionsCancelEventArgs^

A WebPartConnectionsCancelEventArgs that contains the event data.

The OnWebPartsConnecting method raises the WebPartsConnecting event, which occurs when two controls attempt to establish a connection. The method provides the opportunity to cancel the connection attempt. If the connection is successful, the WebPartsConnected event follows.

Page developers can provide a custom handler for the associated event by adding the OnWebPartsConnecting attribute to the <asp:webpartmanager> element on a Web page, and then assigning a custom method name to the attribute.

Notes to Inheritors:

Developers who create derived WebPartManager classes can override the OnWebPartsConnecting method to customize the event handling.
