Syntax question II

With EEs help, I have the code like this

    protected void MoveAllbtn_Click(object sender, EventArgs e)
    {
       

        Button button = (Button)sender;
        string buttonId = button.ID;

        foreach (var item in listBox1.Items.Cast<ListItem>().Reverse())
        {
            //somthing here
        }

        System.Web.UI.AttributeCollection attributColl = (System.Web.UI.AttributeCollection)MoveAllbtn.Attributes;
        if (attributColl != null && attributColl.Count > 0 && attributColl["CustomParameter"] != null)
        {
            string myCustomParameterValue = attributColl["CustomParameter"];
            testBox.Text = myCustomParameterValue;
        }


        
        

        testBox.Text = buttonId;
    }

Select allOpen in new window

I was wondering if there is a way to replace MoveAllbtn (the ID of the button) dynamically. So, buttonId  can be in the code...thanks



System.Web.UI.AttributeCollection attributColl = (System.Web.UI.AttributeCollection)MoveAllbtn.Attributes;
