HitTestLocations is used by HitTest methods to describe the area of the designer hit by mouse clicks and drag and drop operations. Use the HitTestLocations to decide what kind of action to take in response to a successful hit test.

The following example shows the addition of a new branch using a designer based off of the CompositeActivityDesigner class. If CanInsertActivities returns true, a new branch is created using the InsertActivities method. A ConnectorHitTestInfo object is created as a parameter to the InsertActivities method using the location of the workflow designer by specifying the HitTestLocations.Designer flag. When this is finished, the EnsureVisibleContainedDesigner method is used to ensure that the newly added branch is displayed in the workflow designer.

protected override CompositeActivity OnCreateNewBranch()
    return new ParallelIfBranch();
