event

Hello,
I am attempting to bind an event to a variable numbr of dynamically created <asp:button> elements a table. Here is my code :-

// where src = a hashtable of dataObject objects
foreach (dataObject srcobj in src.Values){
   TableRow row = new TableRow();
   TableCell srcname = new TableCell();
   Button nameBtn = new Button();
   nameBtn.Command += new CommandEventHandler(this.nameBtn_Click);
   nameBtn.CommandName = "graphClick";
   nameBtn.CommandArgument = srcobj.id.ToString();

// I have also tried this
   //nameBtn.Attributes.Add("OnCommand", "nameBtn_Click");
   //nameBtn.Attributes.Add("CommandArgument"", srcobj.id.ToString());
   //nameBtn.Attributes.Add("CommandName","name button click");

   nameBtn.ID = "data" + srcobj.id.ToString();
   nameBtn.Text = srcobj.name;
   srcname.Controls.Add(nameBtn);
   row.Cells.Add(srcname);
}
            
protected void nameBtn_Click(object sender, CommandEventArgs e)
        {
            string debug = e.CommandArgument.ToString();
        }

The problem I am having is that it seems as though the click event is never fired, the page posts back but doesn't hit my breakpoint within the click method.

what am I doing wrong?

Cheers
