C#

I have Pdf template with some background design and logo, so we need to pass the data dynamically in to that pdf template using "itextsharp" library. So when we pass the data to the template, it’s overriding the template backgroud design and showing the plain text that we have passed to the 
Template instead of merging with the Template.
Any ideas or suggestions to achieve the functionality would be appreciated.
