i didn't say anything about this Unsure | :~

See that event will fire only when selected Index changed as it is in name. And by default first item is selected so it will not fire untill you select another item

Here is a piece of code that works fine in my system. just check with this you are doing it right...
HTML
-----

<-asp:dropdownlist id="DropDownList1" runat="server"
 0nSelectedIndexChanged="dropdownlist_SelectedIndexChanged" AutoPostBack="True"></asp:dropdownlist>

Code-Behind
------------

 private void Page_Load(object sender, System.EventArgs e) 
{ 
  if (!Page.IsPostBack) { 
    DropDownList1.Items.Insert(0, new ListItem("First", "1")); 
    DropDownList1.Items.Insert(1, new ListItem("Second", "2")); 
    DropDownList1.Items.Insert(2, new ListItem("Third", "3")); 
  }
} 
public void dropdownlist_SelectedIndexChanged(object sender, System.EventArgs e) 
{ 
    Label1.Text = DropDownList1.SelectedItem.Text; 
}

Note: SelectedIndexChanged event will fire only when you change the dropdown item.

just tell me from where u want to click and redirect ur page from grid or button. if grid use grid_rowcommand and get ur text and redirect.

like this
Response.Redirect("abc.aspx?ID=" + ((TextBox)row
.FindControl("TextBox1")).Text);
