hi all

Hi, I am trying to do a three tier architecture of windows application using C#.

Main layout: Inserting Values into a datagridview from two textboxes.

Problem : I have 3 layers in my application UI,Business,Data Layers.(form1.cs,Bal.cs,Dal.cs)

I have created separate c# code files for each, the question is how can I use the textbox or any other controls from form1.cs to dal.cs is there any way doing that.



I am learning how to work with tiered architecture please provide me some help.



Thank you.
