    I set MinLength on Autocomplete.

    However when I click on the "clear" icon of the autocmplete box there are a few unexpected behaviors

    - there is a call to the controller with empty text

    - the dropdown remains open saying "no data found"

    Hello François,

    In our demos when the input is cleared a request is sent to the server and it returns all the items. The No data found message is not displayed:
    Here's the Action that is called:
    public JsonResult GetProducts(string text)
        var northwind = new SampleEntities();
        var products = northwind.Products.Select(product => new ProductViewModel
            ProductID = product.ProductID,
            ProductName = product.ProductName,
            UnitPrice = product.UnitPrice ?? 0,
            UnitsInStock = product.UnitsInStock ?? 0,
            UnitsOnOrder = product.UnitsOnOrder ?? 0,
            Discontinued = product.Discontinued
        if (!string.IsNullOrEmpty(text))
            products = products.Where(p => p.ProductName.Contains(text));
        return Json(products, JsonRequestBehavior.AllowGet);

    Could you share your AutoComplete declaration? This would give us a better idea of how it is configured.
