The code in ItemDataBound event of repeater.

Populating the dropdownlist dynamically.

protected void cpRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    DropDownList ddlType = (DropDownList)e.Item.FindControl("ddlType");
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        SqlConnection SqlCnn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
        SqlCommand SqlCmd = new SqlCommand("select * from CPMEMBERS", SqlCnn);
        SqlDataAdapter SqlAd1 = new SqlDataAdapter(SqlCmd);
        DataSet ds = new DataSet();
        DataTable dt = new DataTable();
        SqlAd1.Fill(dt);
        ddlType.DataTextField = "Type";
        ddlType.DataSource = dt;
        ddlType.DataBind();

        ddlType.SelectedValue = DataBinder.Eval(e.Item.DataItem, "UpdatedType").ToString();
    }
}

Updating and deleting of the records using Item Command Event of repeater

if (e.CommandName == "update")
{
    SqlConnection SqlCnn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
    SqlCommand SqlCmd = new SqlCommand("update CPMEMBERS set Member=@Member, UpdatedType=@UpdatedType where id=@ID", SqlCnn);
    SqlCmd.Parameters.Add("@Member", SqlDbType.VarChar).Value = txtName.Text;
    SqlCmd.Parameters.Add("@UpdatedType", SqlDbType.VarChar).Value = ddlType.SelectedItem.Text;
    SqlCmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = e.CommandArgument;
    try
    {
        SqlCnn.Open();
        SqlCmd.ExecuteNonQuery();

    }
    catch (Exception ex)
    {
        ex.Message.ToString();
    }
    finally
    {
        if (SqlCnn.State == ConnectionState.Open)
            SqlCnn.Close();
    }
    BindRepeater();
}
if (e.CommandName == "delete")
{
    SqlConnection SqlCnn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
    SqlCommand SqlCmd = new SqlCommand("delete CPMEMBERS where id=@ID", SqlCnn);
    SqlCmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = e.CommandArgument;
    try
    {
        SqlCnn.Open();
        SqlCmd.ExecuteNonQuery();

    }
    catch (Exception ex)
    {
        ex.Message.ToString();
    }
    finally
    {
        if (SqlCnn.State == ConnectionState.Open)
            SqlCnn.Close();
    }
    BindRepeater();
}
