ASP usercontrol with C#

ASP usercontrol with C#

• smcneese

  You can use a delegate. A delegate is like an event, except that you can define t he function signature

  delegate void MyFunc(int i);

  public MyFunc Callback = null;

  Then in the code that finds the int

  if (Callback != null) Callback(myInt);

  Then you hook this up like any other delegate

  in your other class

  void myDelegateHandler(int i)

  {

  // whatever

  }

  myUserControl.Callback += new MyUserControlType.MyFunc(this.myDelegateHandler);

  www.asp.net is the right place for future ASP.NET questions.

  Ok so this is the function that has the int varable that I whant wucg us called samtals
  sorry the varibals are in icelantic. Well you get the point I would thingk
  private void RenderShoppingChart()
  {
  ArrayList list = Session["vorur"] as ArrayList;
  if (list != null)
  {
  BulletedList1.Items.Clear();
  foreach (Vorur v in list)
  {
  samtals += v.VorurVerd;
  string s = string.Format("{0} - {1}", v.VorurStaerd, v.VorurNafn);
  BulletedList1.Items.Add(new ListItem(s));
  }
  lblMatsedillSamtals.Text = string.Format("Samtals {0} kr", samtals);
  }
  }
  
  Basicily what is happening in the big picture that I am adding a product to a list and showing the total price with "samtals"
  
  On a ASP webpage there is a butten and wen I push it I should get the number contained in "samtals"
  
  I just don't get were I should put the code that you posted
  
  By the way total newbe dooing a first year asighnment and sorry if there are any spelling mistakes
