I'm trying to allow a user select their marital status that will update a field in a database. This is fine when it is the user's first time, but if they want to update it again, it will not update. If I choose a data source, if they wish to update, they aren't given any other options in the DDL other that what was selected the first time. *ASPX* <pre><code><asp:DropDownList ID="DDLMarital" runat="server" TabIndex="1"> <asp:ListItem Value = "Single" Text = "Single">Single</asp:ListItem> <asp:ListItem Value = "Married" Text = "Married">Married</asp:ListItem> <asp:ListItem Value = "Separated" Text = "Separated">Separated</asp:ListItem> <asp:ListItem Value = "Divorced" Text = "Divorced">Divorced</asp:ListItem> </asp:DropDownList> </code></pre> ****ASPX.VB***** <pre><code>'binding... </code></pre> Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load <pre><code> Dim dvSql4 As DataView = DirectCast(SqlMarital.Select(DataSourceSelectArguments.Empty), DataView) For Each drvSql4 As DataRowView In dvSql4 DDLMarital.Text = drvSql4("Marital_Status").ToString() Next </code></pre> End Sub 'updating the database when the "Next" button is clicked Protected Sub BtnNext_Click(sender As Object, e As System.EventArgs) Handles BtnNext.Click <pre><code> Dim con As New SqlConnection Dim cmd As New SqlCommand con.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\scrummingit2.mdf;Integrated Security=True;User Instance=True" con.Open() cmd.Connection = con cmd.CommandText = ("UPDATE Student_Personal_Details SET Marital_Status = @Marital WHERE Student_No = @StudentNo") Dim maritalParam As New SqlParameter("@Marital", DDLMarital.Text) Dim studentNoParam As New SqlParameter("@StudentNo", lblEnrolmentStudentNumber.Text) lblEnrolmentStudentNumber.Text = Session("Student") cmd.Parameters.Add(maritalParam) cmd.Parameters.Add(studentNoParam) cmd.ExecuteNonQuery() con.Close() </code></pre> End Sub Can anyone help? Getting desperate now after days of not finding any answers on Google.

Guidance

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.
