Layers

[kenexcelon]

I am learning a new way of setting up ASP .NET projects. So far, I've been using a structured approach as I am learning. However, now I am setting up projects using 3 layers, bl, dl, and dal. My question is, how would you databind a gridview going through all the layers? Any good examples? I couldn't really find any. Thanks

You can create like this BO [Business Object] BLL [Business Logic Layer] DAL [Data Access Layer] Now First we define the BO Here you can create some property according to need.. Now You can create your BO,BLL class objects into your UI code behind... Now you assign the BO property BO oBO=new BO; myBLL oMyBLL=new myBLL(); oBO.PropertyName=ControlName.Text; dataset ds=oMyBLL(BO oBO); Now refer to you BLL Create a class in you BLL folder which has the paratemer of BO public dataset class myBAL(BO oBo) { } and this BO class call the DAl like this public dataset class myBAL(BO oBO) { return oDAL.YourSelectMethod(BO oBO) } Now DAL CLASS is like this public dataset Class myDAL(BO oBO) { // Your Code for select is here } above is the secenirio That will be some error.. Hope you solve it into you level. Here I given only example
