Question

I’m just stumped on what to do with this code, I’m just trying to implement a ‘no duplicates’ catch on my insert customer form, but it just slips through my if statement to the else everytime. This is the source. Also I tried a .Equals with the same results 🙁

 Protected Sub srcAllClients_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles srcAllClients.Inserting
        'Establish Variables
        Dim emailAddress As String
        Dim srcUsers As SqlDataSource = New SqlDataSource()

        srcUsers.ConnectionString = ConfigurationManager.ConnectionStrings("ISSD21ConnectionString").ConnectionString

        Dim view As DataView
        view = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), DataView)
        srcUsers.SelectCommand = "SELECT EmailAddress FROM ISSDClients"
        srcUsers.DataSourceMode = SqlDataSourceMode.DataReader
        Dim reader As IDataReader
        reader = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), IDataReader)

        emailAddress = FormView1.FindControl("txtEmail").ToString

        While reader.Read()
            If reader("EmailAddress") = (emailAddress) Then
                lblError.Text = "Your Email is NOT Unique!"
                'this is where we cancel the update and return an error
            Else
                lblError.Text = "Your Email is Unique!"
                'nothing needs to happen, maybe just tell them that it went through
            End If
        End While

        reader.Close()
    End Sub

emailAddress = FormView1.FindControl("txtEmail").ToString

is just going to return the string “System.Web.UI.WebControls.TextBox”. You’re not accessing the actual property of the control that would hold the text value, you’re just calling ToString() on the control itself.

Try this:

Dim emailBox As TextBox = CType(FormView1.FindControl("txtEmail"), TextBox);
emailAddress = emailBox.Text
