+## Add a date field to a PDF form
+
+This section explains how to add a date text box field to a PDF form using the Syncfusion PDF library. The field is prefilled with a sample date and uses JavaScript-based formatting to enforce the date format, validate input, and automatically format user entries.
+
+The following code example illustrates how to add a date field to a PDF form.
+
+{% tabs %}  
+{% highlight c# tabtitle="C# [Cross-platform]" %}
+
+using Syncfusion.Drawing;
+using Syncfusion.Pdf;
+using Syncfusion.Pdf.Interactive;
+
+// Create a new PDF document
+using (PdfDocument pdfDocument = new PdfDocument())
+{
+    // Add a new page to the PDF document
+    PdfPage pdfPage = pdfDocument.Pages.Add();
+    // Create a text box field for entering the name
+    PdfTextBoxField nameField = new PdfTextBoxField(pdfPage, "DateField");
+    nameField.Bounds = new RectangleF(10, 40, 200, 20);
+    nameField.ToolTip = "Date";
+    nameField.Text = "12/01/1995";
+    //Set the scriptAction to submitButton
+    nameField.Actions.KeyPressed = new PdfJavaScriptAction("AFDate_KeystrokeEx(\"m/d/yy\")");
+    nameField.Actions.Format = new PdfJavaScriptAction("AFDate_FormatEx(\"m/d/yy\")");
+    nameField.Actions.Validate = new PdfJavaScriptAction("AFDate_Validate(\"m/d/yy\")");
+    // Add the field to the form
+    pdfDocument.Form.Fields.Add(nameField);
+    // Save the PDF document
+    pdfDocument.Save(Path.GetFullPath(@"Output/Output.pdf"));
+}
+{% endhighlight %}
