Hi David,
Thank you for your interest in Syncfusion products.
You can align the tabstrip with multipage control vertically by adjusting the tablayout and textlayout and placing the tabstrip and multipage control in a separate table cell. Please refer the sample in the link mentioned below:

Please try running the above sample and let me know if this helps.
