    string newZoom = this.toolStripComboBoxZoom.Text.Trim();
    if (newZoom.EndsWith("%"))
        newZoom = newZoom.Substring(0, newZoom.Length - 1);

    if (newZoom.Length > 0)
    {
        try
        {
            this.workflowViewHost.WorkflowView.Zoom = Convert.ToInt32(newZoom);
        }
        catch
        {
            this.workflowViewHost.WorkflowView.Zoom = 100;

    else
    {
        this.workflowViewHost.WorkflowView.Zoom = 100;
