WebPartManager.BeginWebPartConnecting Method

Starts the process of connecting two WebPart controls.

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

public virtual void BeginWebPartConnecting(
	WebPart webPart
)

Parameters

webPart
Type: System.Web.UI.WebControls.WebParts.WebPart

The control for which the connection is being formed.

ExceptionCondition
ArgumentNullException

webPart is null.

InvalidOperationException

The current display mode on the page is not ConnectDisplayMode.

ArgumentException

webPart is closed.

- or -

webPart is not part of the Controls collection.

-or -

webPart is equal to the SelectedWebPart control.

The BeginWebPartConnecting method exists so that the process of forming connections between controls can be done in distinct stages, giving developers more control over the connection process. The method performs a set of initial checks to ensure that webPart is in a state where a connection can legitimately be formed. If webPart passes all the checks, it is then set as the currently selected control (see the SelectedWebPart property), and the connecting process can continue.

Notes to Inheritors

Developers who need to extend the WebPartManager control might want to override this method in a derived class. One approach would be to call the base method, and then add some additional custom handling; or you might want to completely customize the process of starting a connection between controls. For example, you might want to verify that certain data is available before creating the connection.
