how can i set all the items to dropdownList

Question

HI ive got the following code.

 

protected void AdditionalDevice_ItemCommand(object source, RepeaterCommandEventArgs e)
        {
            // set all your asp controls (label, ddl, textbox.etc)
            DropDownList ddlAdditionalDevicesEdit;
            try
            {
                switch (e.CommandName)
                {
                    case "Edit":
                        // hide labels
                        var label = (Label)e.Item.FindControl("lblDeviceType");
                        var macadreslabel = (Label)e.Item.FindControl("lblMacAdressDevice");
                        label.Visible = false;
                        macadreslabel.Visible = false;

                        // set the value of the Label in the ddl
                        //foreach (var item in AdditionalDevices.Items)
                        //{
                        //    var result = (DropDownList)e.Item.FindControl("additionalDeviceDropDownList");
                        //    ddlAdditionalDevicesEdit.Items.Add(result.SelectedItem.Text);
                        //}----> not working!!!

                        ddlAdditionalDevicesEdit = (DropDownList)e.Item.FindControl("additionalDeviceDropDownList"); ---> this is showing only one result i need to have all of them

                        // show ddl
                        ddlAdditionalDevicesEdit.Visible = true;

                        // show textbox
                        var macAdressTextBox = (TextBox)e.Item.FindControl("deviceMacAdressTextBox");
                        macAdressTextBox.Text = macadreslabel.Text;
                        macAdressTextBox.Visible = true;

                        // hide edit_button
                        ((Button)e.Item.FindControl("additionaldevice_editbutton")).Visible = false;

                        // Hide delete button
                        ((Button)e.Item.FindControl("additionaldevicedeleteButton")).Visible = false;

                        // show submit_button
                        ((Button)e.Item.FindControl("additionaldevicesubmitbutton")).Visible = true;

                        // show cancel_button
                        ((Button)e.Item.FindControl("additionaldeviceCancelButton")).Visible = true;

                        // Hide rows wich are not editted
                        foreach (RepeaterItem item in AdditionalDevices.Items)
                        {
                            if ((item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem) &&
                                (e.Item.ItemIndex != item.ItemIndex))
                            {
                                item.FindControl("additionaldevice_editbutton").Visible = false;
                                item.FindControl("additionaldevicedeleteButton").Visible = false;
                            }
                        }

                        break;

                    case "Submit":
                        break;

                    case "Delete":
                       break;
                }

            }
            catch (Exception ex)
            {
                App.HandleException(ex);
                ShowFailureText();
            }
        }

However the line   ddlAdditionalDevicesEdit = (DropDownList)e.Item.FindControl("additionalDeviceDropDownList"); is only setting one of the two items to the dropdownlist, how can i add both of them ???

 

thnx
