        XRTextBox xrTextBox = xrControl.Value as XRTextBox;
        if (xrTextBox != null){
            xrTextBox.CalculateDocumentVariable += OnCalculateDocumentVariable;
        }
    }
}
private void OnCalculateDocumentVariable(object sender, DevExpress.XtraRichEdit.CalculateDocumentVariableEventArgs e){
    if(e.VariableName=="DataItem0")
        e.Value += " (Custom text for Exporter)";
}
