Based-off your reply to Zollistic’s answer, you could do this…
Apply this event to all your all your worker buttons…
protected void button_Click(object sender, EventArgs e)
{
if (Session["Worker"] == null) Session["Worker"] = "";
Session["Worker"] += button.Text + ",";
}
Now Session[“Worker”] has a character-delimited list of all the clicked buttons. The character in this example is a comma; but you can change it to whatever you want (i.e. a pipe “|”).
solved Is there some way to go on the previous page get the pressed button text?
