How to call an ASPX page function in another project?

When clicking insert I call a project to make the business rules, at a certain moment I need to call a C# function that is on the page and after the return of this function continue on making the rules of business.

as I call this function?

Answer 1

Hello.

For this to happen, you will need to reference your project (not Solution) in your BLL. However, if you have already referenced BLL in your application, VS will not allow.

A solution that I use a lot is to keep as many methods as possible in BLL, even if it is something specific, so if you need to use in aspx or in BLL itself, just call it normally.

I hope I’ve helped!!!

You could pass the method to be caller for BLL as a delegate, and then use the delegate to call the method.

Example:

Code of the BLL:

public void RegraInserir(Action metodo)
{
    metodo(); // chamando o método passado na forma de delegate
}

Page code:

public void buttonInserir_Click(EventArgs e)
{
    businessLayer.RegraInserir(this.Metodo);
}

private void Metodo()
{
    // método que será chamado pela BLL
}
