    <p>I was put in a situation where I was forced to create a procedure that uses two data tables such as this:</p> <pre><code>ALTER PROCEDURE [sesuser].[Login_GetUserList] ( @beginsWith NVARCHAR(20) = NULL, @SortBy nvarchar(20) = NULL, @sortByDirection nvarchar(5) = N'ASC' ) AS BEGIN DECLARE @searchStr NVARCHAR(21) IF @beginsWith IS NULL SET @beginsWith = N'' ELSE SET @beginsWith = dbo.SuperTrim(@beginsWith); IF LEN(@beginsWith) &gt; 0 SET @searchStr = @beginsWith + N'%' ELSE SET @searchStr = N'%' DECLARE @sqlSTR NVARCHAR(4000) DECLARE @sqlOffice NVARCHAR(100) DECLARE @sqlOfficeID NVARCHAR(10) DECLARE @sqlEndSTR NVARCHAR(4000) SET @sqlSTR = N' SELECT [SESLoginID] AS LoginID ,[SESSuspended] AS LoginSuspended ,[SESAdmin] AS Role_Admin ,[SESLoginID] ,[SESFirstName] ,[SESLastName] ,[SESEmail] ,[SESSuspended] FROM sesuser.SESLogin WHERE SESFirstName LIKE ''' + @searchStr + '''' SET @sqlOfficeID = N' SELECT [SESLoginID] FROM sesuser.SESLogin WHERE SESFirstName LIKE ''' + @searchStr + '''' SET @sqlOffice = N' SELECT [OfficeName] FROM sesuser.Office WHERE OfficeID LIKE ''' + @sqlOfficeID + '''' SET @sqlEndSTR = @sqlSTR + @sqlOffice PRINT @sqlEndSTR EXEC sp_ExecuteSQL @sqlEndSTR END </code></pre> <p>so as I understand it, this code supposed to in a table of office IDs and equivalent Office Name to replace the office ID with a Name in the other table and return it.</p> <p>I then use the retrieve data string in a method in my c# code:</p> <pre><code>public static DataTable GetUserList(string beginsWith, out string errMessage, string sortBy, string sortByDirection) { DataTable dt = null; int errNum = 0; string sql = "[sesuser].[Login_GetUserList]"; SqlDataAdapter adap = null; SqlParameter param = null; errMessage = ""; SqlConnection conn = Functions.Database.DBConnect(out errNum); try { SqlCommand cmd = new SqlCommand(sql); cmd.Connection = conn; cmd.CommandType = CommandType.StoredProcedure; param = new SqlParameter("@beginsWith", SqlDbType.NVarChar, 40); param.Value = string.IsNullOrEmpty(beginsWith) ? "" : beginsWith.Trim(); cmd.Parameters.Add(param); cmd.Parameters.AddWithValue("@SortBy", sortBy); cmd.Parameters.AddWithValue("@sortByDirection", sortByDirection); adap = new SqlDataAdapter(cmd); dt = new DataTable(); adap.Fill(dt); } catch (Exception ex) { errMessage = ex.Message; } finally { Functions.Database.DBClose(conn); } return dt; } </code></pre> <p>and later in my asp.net code I call back office name</p> <pre><code>&lt;asp:BoundField DataField="OfficeName" HeaderText="Business Unit" ReadOnly="True" /&gt; </code></pre> <p>The problem is, it errors, saying that it cant find <code>OfficeName</code>.</p> <p>Is there something I forgot? Or am I doing it wrong?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
