Question

I have a class Lot with a function AddPiece(piece).

I also have a Page with a button btnPanel that on click fires the function

public void btnPanel_OnClick(object sender, EventArgs e){}

I want to call the btnPanel_OnClick from the Addpiece function but when I try to do it it does not show in the intlliSense and I get this compilation error “The name ‘btnPanel_OnClick’ does not exist in the current context”. Both classes are in the same namespace. Is this possible?

Here is what I have:

namespace GraphicW_Array
{
  public partial class Board : System.Web.UI.Page
  {
    public void btnPanel_OnClick(object sender, EventArgs e)
    {
      ...code...
     }
   }
 }

and

namespace GraphicW_Array
{
  public class Lot
  {
    public void addPiece(int piece)
    {
        lotPresent[lotLoad] = piece;
        lotLoad++;
    }
  }
}

I think the answer is yes you can but you probably don’t want to. To call the method you need and instance of your page class so you could do

namespace GraphicW_Array
{
  public class Lot
  {
    public void addPiece(int piece)
    {
        lotPresent[lotLoad] = piece;
        lotLoad++;
        var myPage = new Board();
        myPage.btnPanel_OnClick(null,EventArgs.Empty);
    }
  }
}

But what would that actually do? I have no idea because you haven’t posted the code but i suspect it won’t do anything useful for you.

What are you actually trying to achieve?

Maybe this is want you want

namespace GraphicW_Array
    {
      public class Lot
      {
        public void addPiece(int piece, Board myPAge)
        {
            lotPresent[lotLoad] = piece;
            lotLoad++;
            myPage.btnPanel_OnClick(null,EventArgs.Empty);
        }
      }
    }

Then in your page you can call it like this:

var myLot = new Lot();
myLot.addPiece(4,this);
