How to handle dynamic buttons?

[Mercvapor]

I created buttons dynamically with a loop. Into a table and it was successfully added.
Here's a part of my code.


for (int i = 0; i < 6; i++)
{
Button btn = new Button();
btn.Text = "Available";
btn.ID = "btn" + i;
btn.Click += new System.EventHandler(btn_Click);
tc.Controls.Add(btn);
}

public void btn_Click(object sender, System.EventArgs e)
{
Button currentButton = (Button)sender;
string ID = currentButton.ID;
switch(ID)
{
case "btn1": subjectID = subjectIDs[0]; break;
case "btn2": subjectID = subjectIDs[1]; break;
case "btn3": subjectID = subjectIDs[2]; break;
case "btn4": subjectID = subjectIDs[3]; break;
case "btn5": subjectID = subjectIDs[4]; break;
case "btn6": subjectID = subjectIDs[5]; break;
}
}


But when I click the buttons that were created, the event isn't firing.
Is my button handler correct?
