Dropdown in Datagrid (OnSelectedIndexChanged)

The eternal dropdown in a datagrid...
I want to be able to change the value of a dropdownlist in a row, and capture that change...
I think I have set up the method, but the "SelectedIndexChanged" method never gets called!!

I have found several examples of how to do this in C#,
but none of them seem to be working.

*****************************
here is my aspx:
*****************************
<asp:TemplateColumn HeaderText="Party Type">
      <ItemTemplate>            
            <asp:DropDownList runat="server" id="partyTypeDD" Font-Names="Verdana, Arial, sans-serif" AutoPostBack="true" OnSelectedIndexChanged='<%# partygrid_SelectedIndexChanged %>' DataSource='<%# GetPartyTypeList() %>' DataTextField="dictionary_name" DataValueField="dictionary_code" >
               </asp:DropDownList>
        </ItemTemplate>
</asp:TemplateColumn>


*****************************
here is my codebehind:
*****************************

protected void partygrid_SelectedIndexChanged(object sender, System.EventArgs e)
{                  
        // I never get here!!!!
      DropDownList list = (DropDownList)sender;
                  
      String partyTypeValue = list.SelectedValue.ToString();
      String partyTypeiValue = list.SelectedIndex.ToString();

}







Do I need something like either of these to "wire" the event to the handling method???

//this.partygrid.SelectedIndexChanged += new System.EventHandler(this.partygrid_ItemDataBound);
//this.partyTypeDD.SelectedIndexChanged += new System.EventHandler(this.partygrid_SelectedIndexChanged);



thanks for any help!!!

have you tried this?

<asp:TemplateColumn HeaderText="Party Type">
     <ItemTemplate>          
          <asp:DropDownList runat="server" id="partyTypeDD" Font-Names="Verdana, Arial, sans-serif" AutoPostBack="true" OnSelectedIndexChanged="partygrid_SelectedIndexChanged" DataSource='<%# GetPartyTypeList() %>' DataTextField="dictionary_name" DataValueField="dictionary_code" >
               </asp:DropDownList>
        </ItemTemplate>
</asp:TemplateColumn>

cdfllc,

you do not need the code delimiters around the name of the function that is called when using AutoPostBack feature.  PeterFearn is correct

OnSelectedIndexChanged='partygrid_SelectedIndexChanged'
NOT
OnSelectedIndexChanged='<%# partygrid_SelectedIndexChanged %>'
