Answer 1

ImageButton imbtnAdd = new ImageButton();
imbtnAdd.ID = "imbtn" + columnName;
imbtnAdd.ImageUrl = "btn_add_icon.gif";
imbtnAdd.Width = 20;             

imbtnAdd.Click += imbtnAdd_Click;

container.Controls.Add(imbtnAdd);

// ...

private void imbtnAdd_Click(object sender, EventArgs e)
{
    // handle event
}

Jrista's answer is correct.

Although, if you want to implement different handlers for all the buttons and you are using .Net 3.0 or above, you can use lambdas:

imbtnAdd.Click += (object sender, EventArgs e) =>
{
    // Code handling code goes here...
};
