Question

As you can see, I have a method to retrieve fields from my table. In my view, I do the search in two textbox.

ClientID is a string, so no problem it works. But OrderId is an Int, so I use ToString() but it still don’t work.

Am I wrong in the way I wrote my second IF condition for OrderId ? Thanks for your help

public ActionResult Search(string searchString, string searchOrder)
{  
    var user = from m in db.Order   
               select m;

    if (!String.IsNullOrEmpty(searchString))
    {
        user = user.Where(s => s.Order.ClientID.Contains(searchString));
    }         

    if (!String.IsNullOrEmpty(searchOrder))
    {
        user = user.Where(c => c.Order.OrderId.ToString().Contains(searchOrder));
    }

    return this.View("Order", "PrintView", user);
}

To search with number, change the method in question to the following :

 public ActionResult PrintOrders(string searchString, int searchOrder = 0)
    {
        var user = from m in db.OrderDetails   
                   select m;

        if (!String.IsNullOrEmpty(searchString))
        {
            user = user.Where(s => s.Order.ClientID.Contains(searchString));               
        }

        if (searchOrder > 0)
        {
            user = user.Where(c => c.Order.OrderId == searchOrder);               
        }

        return this.ViewPdf("Order", "PrintView", user);
    }

Another method is :

    public ActionResult PrintOrders(string searchString, string searchOrder)
    { 
        var user = from m in db.OrderDetails   
                   select m;

        if (!String.IsNullOrEmpty(searchString))
        {
            user = user.Where(s => s.Order.ClientID.Contains(searchString));               
        }

        int tmp = Int32.Parse(searchOrder);

        if (tmp != 0)
        {
            user = user.Where(c => c.Order.OrderId == tmp);
        }

        return this.ViewPdf("Order", "PrintView", user);
    }

And the view looks like that :

@using (Html.BeginForm("PrintOrders", "Historic", FormMethod.Get, new { target = "_blank" }))
{

   Search by Client ID : @Html.TextBox("searchString")

   Search by Order ID : @Html.TextBox("searchOrder")

  <input type="submit" value="Search" />
}
