private void addButton_Click(object sender, EventArgs e)
{
    SequentialWorkflowRootDesigner rootDesigner = this.workflowPanel.GetWorkflowView().RootDesigner as SequentialWorkflowRootDesigner;
    int viewId = rootDesigner.ActiveView.ViewId;
    if (viewId == 1)
    {
        this.workflowPanel.OnCodeActivityAdded();
    }
    else
    {
        DialogResult resultBox = MessageBox.Show("This sample supports adding a code activity only in workflow view");
    }
}

Private Sub addButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addButton.Click
    Dim viewId As Integer
    Dim rootDesigner As SequentialWorkflowRootDesigner
    rootDesigner = Me.workflowPanel.GetWorkflowView().RootDesigner
    viewId = rootDesigner.ActiveView.ViewId
    If viewId = 1 Then
        Me.workflowPanel.OnCodeActivityAdded()
