UserPromptRespondent

FieldOptions.UserPromptRespondent property

Gets or sets the respondent to user prompts during field update.

public IFieldUserPromptRespondent UserPromptRespondent { get; set; }

Remarks

If the value of this property is set to null, the fields that require user response on prompting (such as FieldAsk or FieldFillIn) are not updated.

The default value is null.

Examples

Shows how to create an ASK field, and set its properties.

public void FieldAsk()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Place a field where the response to our ASK field will be placed.
    FieldRef fieldRef = (FieldRef)builder.InsertField(FieldType.FieldRef, true);
    fieldRef.BookmarkName = "MyAskField";
    builder.Writeln();

    Assert.AreEqual(" REF  MyAskField", fieldRef.GetFieldCode());

    // Insert the ASK field and edit its properties to reference our REF field by bookmark name.
    FieldAsk fieldAsk = (FieldAsk)builder.InsertField(FieldType.FieldAsk, true);
    fieldAsk.BookmarkName = "MyAskField";
    fieldAsk.PromptText = "Please provide a response for this ASK field";
    fieldAsk.DefaultResponse = "Response from within the field.";
    fieldAsk.PromptOnceOnMailMerge = true;
    builder.Writeln();

    Assert.AreEqual(
        " ASK  MyAskField \"Please provide a response for this ASK field\" \\d \"Response from within the field.\" \\o",
        fieldAsk.GetFieldCode());

    // ASK fields apply the default response to their respective REF fields during a mail merge.
    DataTable table = new DataTable("My Table");
    table.Columns.Add("Column 1");
    table.Rows.Add("Row 1");
    table.Rows.Add("Row 2");

    FieldMergeField fieldMergeField = (FieldMergeField)builder.InsertField(FieldType.FieldMergeField, true);
    fieldMergeField.FieldName = "Column 1";

    // We can modify or override the default response in our ASK fields with a custom prompt responder,
    // which will occur during a mail merge.
    doc.FieldOptions.UserPromptRespondent = new MyPromptRespondent();
    doc.MailMerge.Execute(table);

    doc.UpdateFields();
    doc.Save(ArtifactsDir + "Field.ASK.docx");
}

/// <summary>
/// Prepends text to the default response of an ASK field during a mail merge.
/// </summary>
private class MyPromptRespondent : IFieldUserPromptRespondent
{
    public string Respond(string promptText, string defaultResponse)
    {
        return "Response from MyPromptRespondent. " + defaultResponse;
    }
