    Dim str As String =     ConfigurationManager.ConnectionStrings("dbSurvey").ConnectionString
    Dim conn As New SqlConnection(str)

    Dim fetch As String = "Select * from table_name"
    Dim cmd As SqlCommand = New SqlCommand(fetch, conn)

    Dim objAdpt As SqlDataAdapter = New SqlDataAdapter(cmd)
    Dim objDt As DataTable = New DataTable()
    objAdpt.Fill(objDt)

Dim dta As DataTable = obj.FetchSurveyResult
        If MultiView1.ActiveViewIndex = 2 Then
              txtBox.Text = dta.Rows(0)("Location1")
        End If
