Any tip on how to implement this?
I would like this feature and would not mind to implement it myself and share it with you.
But i don't know where to start

There are several ways:

1. If standard export actions are based on model settings and collectionSource data in list editor (you will know it by discovering DX sources) - you can adapt it to XafB (maybe there are not implemented some interface functions or something like this - it's hard to say now why it s not displayed). But i think it's based on editor's export functionality (like ASPxGridView and it's Win analogue) - so, we couldn't use it, because it's only call control export functionality and returns result (but I'm not entirely sure about this, it need to be discovered)

2. Add your own ExportActions in controller, show it to user only if editor is assignable from XafBootstrapTableEditor, generate xlsx/pdf files on action's choice execute and return generated result to user by Response (action must be synchronous to return data correctly, to do this check IsPostBackRequired in action model and use ResponseWriter.WriteFileToResponse(stream, nomefile)). In this way you can implement all logic in one controller.

The main work will be to write export logic, that generates files from collection source data. You can try to use existing DevEx functions/controls/libs (for example based on ASPxGridView or other controls).

I have added the export function by adding the IExportable interface to XafBootstrapTableEditor

and the following code

public void OnExporting()
{
var printableEditor = new ASPxGridListEditor(ListView);
printableEditor.CreateControls();
printableEditor.Setup(collection,App);
printableEditor.Grid.Visible = false;
aspxGridViewExporter.Page = control.Page;
control.Controls.Add(printableEditor.Grid);
}
private ASPxGridViewExporter aspxGridViewExporter;
public List SupportedExportFormats { get {
if(Printable == null) {
return new List();
}
else {
return new List() {
ExportTarget.Csv,
ExportTarget.Html,
ExportTarget.Image,
ExportTarget.Mht,
ExportTarget.Pdf,
ExportTarget.Rtf,
ExportTarget.Text,
ExportTarget.Xls,
ExportTarget.Xlsx
};
}
}}

    public IPrintable Printable
    {
        get { aspxGridViewExporter = new ASPxGridViewExporter(); return aspxGridViewExporter; }
    }

    public event EventHandler<PrintableChangedEventArgs> PrintableChanged;
