I’m handling the onSelectIndexChanged event. An event is raised when the DropDownList selection changes. the problem is that the DropDownList still returns the old values for SelectedValue and SelectedIndex. What am I doing wrong?

Here is the DropDownList definition from the aspx file:

<div style='margin: 0px; padding: 0px 1em 0px 0px;'>     <span style='margin: 0px; padding: 0px; vertical-align: top;'>Route:</span>     <asp:DropDownList id='Select1' runat='server' onselectedindexchanged='index_changed' AutoPostBack='true'>     </asp:DropDownList>     <asp:Literal ID='Literal1' runat='server'></asp:Literal> </div>

Here is the DropDownList OnSelectedIndexChanged event handler:

protected void index_changed(object sender, EventArgs e) {     decimal d = Convert.ToDecimal( Select1.SelectedValue );     Literal1.Text = d.ToString(); }

  1. Do you have any code in page load that is by chance re-defaulting the value to the first value?

    When the page reloads do you see the new value?
