Office-Inspired Products
30 October 2023

As you may already know, our Office File API suite now supports the .NET MAUI development platform. In this blog post series, I will share straightforward ways to incorporate many DevExpress Office File API features in your .NET MAUI mobile app. This particular post details how to leverage our Office File API's mail merge capabilities to generate e-mail messages from templates in your DevExpress-powered .NET MAUI app.

By introducing mail merge support in your .NET MAUI app, users can generate Word documents (based on templates) with relative ease and reduce repetitive actions when creating messages with similar content. Since mail merge support can seamlessly integrate with mobile devicecontact management systems, introducing this capability can alsostreamline the recipient selection process.

If mail merge support is on your mobile development radar, the Word Processing Document API (included in our Office File API suite) can load/create templates, bind data sources, and generate/share messages. The library supports IList, ArrayList, and DataTable data sources. You can export generated text to any supported format or send it to an e-mail application.

We have created a GitHub example that demonstrates theuse of our Word Processing Document API. This example sends e-mail messages (generated from an e-mail template) to records in a database. Please refer to the following link for implementation details: DevExpress .NET MAUI Controls - Send Template Messages Using Mail Merge.

Important Note: You must purchase a license to use the DevExpress Office File API within a .NET MAUI app. The DevExpress Office File API (including our Word Processing Document API) ships in the following DevExpress Subscriptions:DevExpress Universal, DXperience, or Office File API.

Example Overview

This sample application displays a contact list within our .NET MAUI Data Grid (DataGridView component). You can swipe the desired contact (to the right) to generatean email. Once you select the template you wish to use, an e-mail app tab appears on-screen. You canedit the document (if required) and send it to the recipient.

Our RichEditDocumentServer acts as the mail merge engine. It is used to populate placeholders within ane-mail template (using the selected contact's information). Once complete, output is sent to the Microsoft Outlook mail app.

For more information on app structure, please refer to the following document: Send Template Messages Using Mail Merge.
