Question

Sorry in advance im going to try and explain this as best as possible….

I have 2 asp.net pages one named membermaster and the second named memberdetails. I created a class library which contains 2 functions

My first function returns a list depending on the search result…

I added a linkbutton to the gridviews first column which when clicked it passes through querystring the membershipgen. What i wanted to do is for my second function i created this

public DataTable GetMembers(int MEMBERSHIPGEN)
{
  DataTable table = null;
  SqlConnection con = null;
  SqlCommand cmd = null;
  SqlDataAdapter ad = null;
  SqlParameter prm = null;
  try
  {
      table = new DataTable();
    using (con = new SqlConnection(connectionString))
    {
        using (cmd = new SqlCommand("usp_getmemberdetail", con))
        {
            using (ad = new SqlDataAdapter(cmd))
            {
                prm = new SqlParameter("@MEMBERSHIPGEN", SqlDbType.Int);
                prm.Value = MEMBERSHIPGEN;
                cmd.Parameters.Add(prm);
                ad.Fill(table);
            }

        }
    }
  }
  catch (Exception ex)
  {
        //write your exception code here
  }
  return table;
}

In the attempt to try and send the membershipgen to this and it return the results. But once i compile the DLL and add it to my project I am not sure how i would reference this function to populate individual textboxes and labels with the information.

What I am trying to do is when a user clicks the viewdetails button on the gridview I can then use that membershipgen that I passed through querystring to populate the page through a stored procedure but the smarts would be stored in a DLL.

You need to change GetMembers to return data instead of void. If you want to use DataTables, you can just modify your code to this:

public DataTable GetMembers(int MEMBERSHIPGEN)
{
    DataTable table = new DataTable();
    SqlConnection con = new SqlConnection(connectionString);

    using (SqlCommand cmd = new SqlCommand("usp_getmemberdetail", con))
    {
        using (SqlDataAdapter ad = new SqlDataAdapter(cmd))
        {
            SqlParameter prm = new SqlParameter("@MEMBERSHIPGEN", SqlDbType.Int);
            prm.Value = MEMBERSHIPGEN;
            cmd.Parameters.Add(prm);
            ad.Fill(table);
            return table;
        }

Then in your Page_Load it might be something like this (more robust than this hopefully):

{
    DataTable table = yourDll.GetMembers(Convert.ToInt32(Request.QueryString["membership"]));
    label1.Text = Convert.ToString(table.rows[0]["Name"]);
}
