    <p>I'm trying to create an option to select a specific entry in a SQL table if multiples exists. The Sub listed below is for a textbox (MOTxt) and a button (GotMO) for checking an MO# to pull from SQL. Based on the number entered, will populate other text boxes on the page with that row's data. There are exceptions to this, where the MONumber will be entered more than once with different data associated with each entry. So, here's my situation. If we have a duplicate MONumber listed in the table, it will populate the textboxes with the first entry it finds for an update. I would like to create a dynamic dropdownlist (that displays only if multiples are found) displaying the 'Name' field entries for each MONumber found, then once the correct name is selected from that list, to then populate the textboxes with that selected datarow.</p> <p>Here's my code behind:</p> <pre><code>Protected Sub GotMONum_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GotMO.Click Dim da As New SqlDataAdapter Dim ds As New DataSet Dim MOLength As String = MOTxt.Text Dim TieOffTemp As Integer Dim QTYTemp As Integer Dim MySelectQuery As String = "SELECT Name,ProdLine,NoRods,TieOffs FROM z_md_Outwrap WHERE MONumber = @MONum" Dim myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("GLoomisDBConnectionString").ConnectionString) Dim myCommand As New SqlCommand(MySelectQuery, myConnection) Message2.InnerHtml = "" Message.InnerHtml = "" If (Me.MOTxt.Text = "") Then MsgBox("Please enter an MO Number to check") Else ' Fills fields based on MO Number myCommand.Parameters.AddWithValue("@MONum", MOTxt.Text) myConnection.Open() da.SelectCommand = myCommand da.Fill(ds, "tblData") myConnection.Close() If ds IsNot Nothing AndAlso ds.Tables.Count &gt; 0 AndAlso ds.Tables(0).Rows.Count &gt; 0 Then NameTxt.Text = ds.Tables("tblData").Rows(0).Item("Name") ProdLineTxt.Text = ds.Tables("tblData").Rows(0).Item("ProdLine") NoRodsTxt.Text = ds.Tables("tblData").Rows(0).Item("NoRods") TieOffsTxt.Text = ds.Tables("tblData").Rows(0).Item("TieOffs") If Integer.TryParse(NoRodsTxt.Text, QTYTemp) Then If Integer.TryParse(TieOffsTxt.Text, TieOffTemp) And TieOffTemp &gt; 0.0 Then AmountVal.Text = "$" &amp; (QTYTemp * TieOffTemp * 0.18) End If End If Else Message.InnerHtml = "No MO# found as entered. Please check for errors." Message.Style("color") = "red" End If End If End Sub </code></pre>

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.
