Please help, i need this to know for my school exam next week!!!

I am creating an Email Client in WPF, so far i have a List<> with messages, for each message is created a user control with a unique tag(1,2,3,..) and data inside the form. The user controls are added dynamically in a wrap panel depends on the number of messages.

Something like this:

I want to raise an event on the user control, for example open a bigger window with the data from the user control.

How should i raise the event, should i create somekind of custom event, becose i need to compare the tag of the usercontrol created in main window so it matches and opens the correct window?

It would likely help if you posted the code you have for generating the dynamic controls; however, wiring up the events is pretty simple.

For example you can do something like this:

C#

MyUserControl ctl = new MyUserContro();
ctl.MouseRaisedEvent += new ...

and in your user control you have properties to expose the events. An example is at http://stackoverflow.com/questions/6192739/how-do-i-raise-an-event-in-a-usercontrol-and-catch-it-in-mainpage[^]

This is the code for dynamically generating user controls:

//Message is the class with properties and List<> listofMessages
foreach (Message item in Message.listofMessages)
{
UserCKocka novUc = new UserCKocka();
novUc.Margin = new Thickness(5);
novUc.Width = 180;
novUc.Height = 180;

//Increase tag number
stTaga++;
//Tag user control with the number stTaga
novUc.Tag = stTaga;

//Adding the datas and image for the newly created user control
Uri slikaPot = new Uri(item.Slika, UriKind.RelativeOrAbsolute);
BitmapImage slika = new BitmapImage(slikaPot);
novUc.slikaKocka.Source = slika;

//Textblock pošiljatelj
novUc.txtPosiljateljKocka.Text = item.Od;
novUc.txtZadevaKocka.Text = item.Zadeva;
novUc.SporociloKocka.Text = item.Vsebina;

wrap.Children.Add(novUc);
}

Thank you for helping me :)

In the raised event you can check the tag property.
