Hi,

I search to merge a document with some special field formated with Bold and new line in a Document. This "special field" come from a RichTextBox.
Is it possible?

Thx in advance

Hi Emmanuelli,
By default, the data source of the merge fields is merged as plain text (using the current formatting). You can, however, create custom type of merge fields by inheriting MergeField class and overriding GetResultFragment method. This method returns DocumentFragment, which means that you can apply the desired formatting and inlude more than one paragraph (i.e. the new lines). Similar approach is demonstrated in this forum thread. Following is a sample implementation of the GetResultFragment method:
protected override DocumentFragment GetResultFragment()
{
    Person customer = this.Document.MailMergeDataSource.CurrentItem as Person;
 
    if (customer == null)
    {
        return null;
    }
 
    if (this.PropertyPath == "FirstName")
    {
        RadDocumentEditor editor = new RadDocumentEditor(new RadDocument());
 
        editor.Insert(Environment.NewLine);
        editor.Insert(customer.FirstName);
        editor.Insert(Environment.NewLine);
 
        editor.Document.Selection.SelectAll();
        editor.ChangeFontWeight(FontWeights.Bold);
 
        return new DocumentFragment(editor.Document);
    }
 
    return null;
}


You can insert such fields using the RadRichTextBox/RadDocumentEditor's InsertField method:

this.radRichTextBox.InsertField(new CustomMergeField() { PropertyPath = "FirstName" });

Don't hesitate to contact us if you have other questions.

Hello Emmanuelli,
Could you explain in more details what is your scenario, as I am having hard time understanding what are you trying to achieve?

Looking forward to your reply.
