Here's a simple example:

C#

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);
    Button button = new Button();
    button.ID = "Button1";
    button.Text = "Button1";
    PlaceHolder1.Controls.Add(button);
    button.Click += new EventHandler(Button1_Click);
}

protected void Button1_Click(object sender, EventArgs e)
{
    Label1.Text = "Button1_Click";
}

The gist of it is that you need to have some sort of server-side object with an event handler attached to your server-side function. Be sure to put ID's on your dynamically created controls.

Use the below code

VB

Dim lnkSortCol As New LinkButton
lnkSortCol.Text = ds.Tables(0).Columns(j).ColumnName
lnkSortCol.ID = "lnkSortCol_" + j.ToString
lnkSortCol.CommandArgument = "Any Value That You Want To Pass To your event"
lnkSortCol.Command += New CommandEventHandler(lnkSortCol_Command)

void lnkSortCol_Command(object sender, CommandEventArgs e)
{
            
}
