Using a DATABOUND Checkboxlist we would like to be able to have a
clientside VB Script that pops up a message box whenever a certain
check box (with a certain value) is checked.  When checking any of the
other checkboxes in the bound list..  nothing will happen.

Remember:  
This is using ASP.NET
The CheckBoxList Control is databound to a database.
The MessageBox must only popup when certain checkboxes (with a certain
value) are checked.
This must be VBScript on the CLIENTSIDE.

Actually for this scenario it would be easier to just use
"asp:checkbox" and manually add them to a placeholder somewhere on the
page.  Just loop through the data and for each row create a new
checkbox (with onclick event) and add it to the place holder. 
Something like:

[C#]
foreach(DataRow row in dt)
{
  CheckBox ck = new CheckBox;
  ck.Text = row["Name"].ToString();
  if(row["EmployeeType"] == 1) 'Add OnClick event only for employees
where employeetype = 1)
  {
    ck.Atrributes["onClick"] = "alert('Hello');";
  }

  checkBoxPlaceHolder.Controls.Add(ck); 'Put checkbox on page
}
