Change Field Update Culture Source
In this tutorial, we will guide you through the process of changing the field update culture source in Word documents using Aspose.Words for .NET. By modifying the culture source, you can control the date formatting during field update and mail merge operations. We will provide you with the necessary C# source code and step-by-step instructions to achieve this.
Prerequisites
Before we begin, ensure that you have the following prerequisites:
- Aspose.Words for .NET library installed on your system.
Step 1: Create a Document and DocumentBuilder
To start, create an instance of the Document class and a DocumentBuilder object:
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Step 2: Insert Content with Specific Locale
Next, set the locale to German and insert fields with date formatting:
builder.Font.LocaleId = 1031;
builder.InsertField("MERGEFIELD Date1 \\@ \"dddd, d MMMM yyyy\"");
builder.Write(" - ");
builder.InsertField("MERGEFIELD Date2 \\@ \"dddd, d MMMM yyyy\"");
In the above code, we set the font locale to German (locale ID 1031) and insert two fields with specific date formatting.
Step 3: Change Field Update Culture Source
To change the field update culture source, use the FieldOptions class:
doc.FieldOptions.FieldUpdateCultureSource = FieldUpdateCultureSource.FieldCode;
In this example, we set the culture used during field update to be chosen from the culture used by the field.
Step 4: Perform Mail Merge
Perform a mail merge operation and specify the date value for the “Date2” field:
doc.MailMerge.Execute(new string[] { "Date2" }, new object[] { new DateTime(2011, 1, 1) });
In this code snippet, we execute the mail merge operation and provide a DateTime value for the “Date2” field.
Step 5: Save the Document
Save the modified document to a file using the Save method of the Document class:
doc.Save(dataDir + "WorkingWithFields.ChangeFieldUpdateCultureSource.docx");
