By the end of this tutorial, you’ll have a firm grasp of how to insert and manipulate combo box content controls, making your documents more dynamic and user-friendly.

Prerequisites

Before we dive into the nitty-gritty of coding, let’s ensure you have everything you need:

  1. Aspose.Words for .NET: Make sure you have the latest version installed. You can download it here.
  2. .NET Framework: Ensure you have the .NET Framework installed on your machine.
  3. Integrated Development Environment (IDE): Visual Studio is recommended for .NET development.
  4. Basic Understanding of C#: This tutorial assumes you have a basic understanding of C# programming.

Import Namespaces

To start using Aspose.Words in your project, you’ll need to import the necessary namespaces. Here’s how you do it:

using Aspose.Words;
using Aspose.Words.Markup;

Alright, let’s get into the fun part – coding! We’ll break down the process into easy-to-follow steps.

Step 1: Set Up Your Project

First things first, set up a new project in your IDE. Here’s how:

  • Open Visual Studio.
  • Create a new C# Console Application project.
  • Install the Aspose.Words for .NET package via NuGet Package Manager. You can do this by running the following command in the Package Manager Console:
    Install-Package Aspose.Words

Step 2: Initialize Your Document

In this step, we’ll initialize a new Word document where we’ll add our combo box content control.

// Path to your document directory
string dataDir = "YOUR DOCUMENT DIRECTORY";

// Initialize the document
Document doc = new Document();

Step 3: Create the Combo Box Content Control

Now, let’s create the combo box content control. This control will allow users to select from a predefined list of items.

// Create a ComboBox content control
StructuredDocumentTag sdt = new StructuredDocumentTag(doc, SdtType.ComboBox, MarkupLevel.Block);

Step 4: Add Items to the Combo Box

A combo box isn’t much use without items to select from. Let’s add some items to it.

// Add items to the ComboBox
sdt.ListItems.Add(new SdtListItem("Choose an item", "-1"));
sdt.ListItems.Add(new SdtListItem("Item 1", "1"));
sdt.ListItems.Add(new SdtListItem("Item 2", "2"));

Step 5: Insert the Combo Box into the Document

Next, we need to insert this combo box into the document. We’ll append it to the body of the first section of our document.

// Append the ComboBox to the document body
doc.FirstSection.Body.AppendChild(sdt);

Step 6: Save Your Document

Finally, let’s save the document so we can see our combo box in action.

// Save the document
doc.Save(dataDir + "WorkingWithSdt.ComboBoxContentControl.docx");
