ASP.Net - handling event from Dropdown inside a Repeater

Hello,
I have dropdown list inside each row of my repeater control. What I need to do is handle the event when a user changes the selected item.

I have attached my repeater code. Here is the code I use for populating the drop downs:

protected void rptTable_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
DataRow row = e.Item.DataItem as DataRow;
DropDownList ddlReimbursement = e.Item.FindControl("ddlStatus") as DropDownList;

ListItem li0 = new ListItem("No Reimbursement", "1");
ListItem li1 = new ListItem("Partially Reimbursed", "2");
ListItem li2 = new ListItem("Fully Reimbursed", "3");

ddlReimbursement.Items.Add(li0);
ddlReimbursement.Items.Add(li1);
ddlReimbursement.Items.Add(li2);

DataRowView drv = e.Item.DataItem as DataRowView;
ddlReimbursement.SelectedValue = drv.Row.ItemArray[16].ToString();
}
}

Please can somebody help me or point me in the right direction for handling the dropdownList selectedIndexChanged event? Thanks

<asp:Repeater ID="rptTable" runat="server" EnableViewState="false" OnItemDataBound="rptTable_ItemDataBound" OnItemCommand="rptTable_ItemCommand">
    <HeaderTemplate>
     </HeaderTemplate>
    <ItemTemplate>
        <tr>     
            <td><asp:DropDownList ID="ddlStatus" runat="server" AutoPostBack="true" EnableViewState="false"></asp:DropDownList></td>
       </tr>
    </ItemTemplate>

Hi Crazyman,
I've added this to my code but seem to have something wrong as I'm getting build errors.

Error 3 A local variable named 'e' cannot be declared in this scope because it would give a different meaning to 'e', which is already used in a 'parent or current' scope to denote something

Code behind

protected void rptTable_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
DataRow row = e.Item.DataItem as DataRow;
DropDownList ddlReimbursement = e.Item.FindControl("ddlStatus") as DropDownList;

ListItem li0 = new ListItem("No Reimbursement", "1");
ListItem li1 = new ListItem("Partially Reimbursed", "2");
ListItem li2 = new ListItem("Fully Reimbursed", "3");

ddlReimbursement.Items.Add(li0);
ddlReimbursement.Items.Add(li1);
ddlReimbursement.Items.Add(li2);

DataRowView drv = e.Item.DataItem as DataRowView;
ddlReimbursement.SelectedValue = drv.Row.ItemArray[16].ToString();

ddlReimbursement.SelectedIndexChanged += delegate(object sender, EventArgs e) { };
}
}

protected void ddlReimbursement_SelectedIndexChanged(object sender, EventArgs e)
{
}

Thanks

Ah, sorry I have got it to build by renaming e and sender. That code compiles but I have added the handler and put a break point on it and it is not being hit when I select any of the dropdown items. It posts back but does not break on the SelectedIndexChanged event!!

protected void rptTable_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//populating the drop downs
DataRow row = e.Item.DataItem as DataRow;
DropDownList ddlReimbursement = e.Item.FindControl("ddlStatus") as DropDownList;

ListItem li0 = new ListItem("No Reimbursement", "1");
ListItem li1 = new ListItem("Partially Reimbursed", "2");
ListItem li2 = new ListItem("Fully Reimbursed", "3");

ddlReimbursement.Items.Add(li0);
ddlReimbursement.Items.Add(li1);
ddlReimbursement.Items.Add(li2);

//create the handler
ddlReimbursement.SelectedIndexChanged += delegate(object sender1, EventArgs ex) { };
}
}

//neither of these breakpoints are being hit :(
protected void ddlReimbursement_SelectedIndexChanged(object sender, EventArgs e)
{
}

protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e)
{
}
