Current State Of Check Box

This tutorial explains how to retrieve and set the current state of a check box content control in a Word document using Aspose.Words for .NET. You can check or uncheck the check box based on its current state.

Prerequisites

To follow this tutorial, you need to have the following:

• Aspose.Words for .NET library installed.
• Basic knowledge of C# and Words Processing with Word documents.

Step 1: Set up the Document Directory

Start by setting up the path to your document directory. Replace "YOUR DOCUMENT DIRECTORY" with the actual path to the directory where your document is located.

string dataDir = "YOUR DOCUMENT DIRECTORY";

Step 2: Load the Document and Retrieve the Check Box Content Control

Load the Word document using the Document constructor, passing the path to the document as a parameter. Then, retrieve the desired check box content control from the document. In this example, we assume that the check box is the first structured document tag in the document.

Document doc = new Document(dataDir + "Structured document tags.docx");
StructuredDocumentTag sdtCheckBox =
	(StructuredDocumentTag)doc.GetChild(NodeType.StructuredDocumentTag, 0, true);

Step 3: Check or Uncheck the Check Box Based on Its Current State

Check if the retrieved structured document tag is of type SdtType.Checkbox. If it is, set the Checked property of the content control to true to check the box. Otherwise, you can leave it unchecked.

if (sdtCheckBox.SdtType == SdtType.Checkbox)
	sdtCheckBox.Checked = true;

Step 4: Save the Document

Save the modified document to the specified directory using the Save method. Provide the desired filename with the appropriate file extension. In this example, we save the document as “WorkingWithSdt.CurrentStateOfCheckBox.docx”.

doc.Save(dataDir + "WorkingWithSdt.CurrentStateOfCheckBox.docx");

Example source code for Current State Of Check Box using Aspose.Words for .NET

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

	Document doc = new Document(dataDir + "Structured document tags.docx");
	// Get the first content control from the document.
	StructuredDocumentTag sdtCheckBox =
		(StructuredDocumentTag) doc.GetChild(NodeType.StructuredDocumentTag, 0, true);
	if (sdtCheckBox.SdtType == SdtType.Checkbox)
		sdtCheckBox.Checked = true;
	doc.Save(dataDir + "WorkingWithSdt.CurrentStateOfCheckBox.docx");

That’s it! You have successfully retrieved and set the current state of a check box content control in your Word document using Aspose.Words for .NET.
