To add an InfoPath Template Part (.XTP) to an InfoPath form, open your form template in InfoPath Designer, then click Add or Remove Custom Controls in the Controls section under the Home tab. Click Add, select Template Part, and click Next to browse to your saved .XTP file. After selecting it and clicking Finish and Close, your new template part will appear in the Custom section of the Controls task pane and can be added to your form by clicking on its name.
