Allowing users to design mergetemplates at runtime

i want to allow users to design mergedtemplates at runtime. i.e; i have a datasource , user can pickup the required fields for the template from the userinterfaces provided(like selecting required fields from listbox) then allowing him to design a template and save.

therefore he can run the application by using this template for letters or labels.

plz reply as soon as possible.

Yes, it is possible to build all kinds of documents dynamically in Aspose.Words. DocumentBuilder can be used for this. the fields are inserted using DocumentBuilder.InsertField method. See the code examples for DocumentBuilder class in our documentation.
