dropdown inside repeater need to find index

Hi all, wondering if i get some tips on how to get the index from dropdownlist inside a control. If you look at the code snippet below i need to get the basketItemId and related quantity.

thanks

<asp:Repeater ID="BasketItemRepeater" runat="server" 
                    onitemdatabound="BasketItemRepeaterDataBound">
                <ItemTemplate>                        
                  <%# DataBinder.Eval(Container.DataItem, "BasketItemId")%>
     
                            <asp:DropDownList ID="QuantityDropDownList" runat="server" AutoPostBack="True" onselectedindexchanged="UpdateQuantity" EnableViewState="true" >
                            </asp:DropDownList>                           
 
                    </ItemTemplate>
 </asp:Repeater>
 
    protected void UpdateQuantity(object sender, EventArgs e)
    {
        DropDownList d = (DropDownList) sender;
 
        // in here i need to get the basketItemId and update the quantity
    }

you have to iterate through the controls if they are inside of grids, repeaters, etc....

thanks for the speedy response. In order to use Item.FindControl i have change EventArgs to RepeaterItemEventArgs. However now i am getting

Compiler Error Message: CS0123: No overload for 'UpdateQuantity' matches delegate 'System.EventHandler'

Here is my code:

          protected void UpdateQuantity(object sender, RepeaterItemEventArgs e)
    {
        DropDownList d = (DropDownList) sender;

        HiddenField basketItemId;
        basketItemId = (HiddenField)e.Item.FindControl("HiddenFieldBasketItemId");


        string mystring = d.Text + basketItemId.Value;

        Response.Write(mystring);
     

    }

oh...you can't do that...you have to leave the argument that you had before in there...that's why you're getting that exception, because UpdateQuantity is expecting EventArgs e....reason being is that the sender is a Dropdownlist, so the Generic or DDL event must be associated with that sender...

What you can do is just use the RepeaterID and access the Item.FindControl that way...

Try this:

protected void UpdateQuantity(object sender, EventArgs e)
{
	DropDownList d = (DropDownList) sender;
 
	// in here i need to get the basketItemId and update the quantity
	RepeaterItem item = (RepeaterItem)d.NamingContainer;
	int i = item.ItemIndex;   // here you get the index of the row that fires the event
	// Continue your update process with the index 
}

        DropDownList quantityDropDownList = (DropDownList)BasketItemRepeater.FindControl("QuantityDropDownList");
        string myString = quantityDropDownList.SelectedValue;
