+# Filling PDF Forms in WPF PDF Viewer
+
+The Syncfusion WPF PDF Viewer supports three types of form-filling:
+
+1. [Filling Form Fields Programmatically](#fill-pdf-forms-programmatically)
+
+ You can fill or update PDF form fields programmatically by acessing the existing Form fields and fill the form fields values. This approach is useful when form data needs to be set dynamically based on application logic.
+
+2. [Form Filling Through User Interface](#fill-pdf-forms-through-the-user-interface)
+
+ Users can fill in PDF form fields directly through the PDF Viewer user interface by typing text, selecting options, or interacting with supported form elements.
+
+3. [Importing Form Field Data](#fill-pdf-forms-through-import-data)
+
+ The PDF Viewer allows you to import form field data into an existing PDF document. This enables pre filled forms using external data sources.
+
+## Fill PDF forms programmatically

+ You can fill or update PDF form fields programmatically by acessing the existing Form fields and fill the form fields values. This approach is useful when form data needs to be set dynamically based on application logic.
+
+The following example demonstrates how to update PDF form field values programmatically:
+
+{% tabs %}
+{% highlight C# %}
+
+private void UpdateTextbox_Click(object sender, RoutedEventArgs e)
+{
+ if (pdfViewer.LoadedDocument.Form != null)

+ {
+ (pdfViewer.LoadedDocument.Form.Fields[1] as PdfLoadedCheckBoxField).Checked = true;
+ }

+
+## Fill PDF forms through the User Interface
+
+The Syncfusion PDF Viewer allows users to fill PDF form fields directly through the user interface without using code. Users can click on form fields and enter or select values based on the field type.
+
+
+
+The PDF Viewer supports common form fields such as text boxes, check boxes, radio buttons, drop-down lists, list boxes, and signature fields. Filled values can be edited at any time, and the entered data is retained during the viewing session.
+
+
+## Fill PDF forms through Import Data
+
+The Syncfusion WPF PDF Viewer allows you to import form field data into an existing PDF document using the [ImportFormData](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfDocumentView.html#Syncfusion_Windows_PdfViewer_PdfDocumentView_ImportFormData_System_String_Syncfusion_Pdf_Parsing_DataFormat_) API. This feature enables you to pre-fill form fields using data from an external source without requiring manual user input.
+
+Imported form field data is automatically mapped to the corresponding form fields in the PDF document based on the field names. Once the data is imported, the populated values are displayed in the PDF Viewer and can be edited through the user interface if required.
+
+{% tabs %}
+{% highlight c# %}
+
+private void button1_Click(object sender, RoutedEventArgs e)
+{
+ //Import PDF form data
+ pdfviewer.ImportFormData("Import.fdf", Syncfusion.Pdf.Parsing.DataFormat.Fdf);
+}
+
+{% endhighlight %}
+{% highlight VB %}
+
+Private Sub button1_Click(sender As Object, e As RoutedEventArgs)
+ 'Import PDF form data
+ pdfviewer.ImportFormData("Import.fdf", Syncfusion.Pdf.Parsing.DataFormat.Fdf)
+End Sub
+
+{% endhighlight %}
+{% endtabs %}
+
+For more details, see [Import Form Data](./import-export-form-fields/import-form-fields).
+
+## How to get the filled data and store it to a database
+
+You can export the filled form field data from the PDF Viewer and store it in a backing system such as a database or file storage. The exported data can later be imported to restore the form state.
+
+For more details, see [Export Form Data](./import-export-form-fields/export-form-fields).

+# Export PDF Form Data from WPF PDF Viewer
+
+The PDF Viewer allows you to export form field data in multiple formats for easy storage or integration. Supported formats:
+
+- [FDF](#export-as-fdf)
+- [XFDF](#export-as-xfdf)
+- [JSON](#export-as-json)
+- [XML](#export-as-xml)
+
+Follow the below steps to export data from PDF document in UI
+
+1. Select **Export** option in the form data toolbar, to save the completed PDF form data as a file in another file format.
+2. In Export Form Data As dialog box, you can select the desired format to save the form data (FDF, XFDF, XML, and JSON).
