you can follow this structure main table Protected Sub Page_Load( ByVal sender As Object , ByVal e As EventArgs) If Not IsPostBack Then Dim constr As String = ConfigurationManager.ConnectionStrings( "Data Source=zoom-pc;Initial Catalog=HR;Integrated Security=True" ).ConnectionString Dim con As New SqlConnection(constr) Dim cmd As New SqlCommand( "SELECT * from Employees" , con) Dim sda As New SqlDataAdapter(cmd) Dim dt As New DataTable() sda.Fill(dt) employees.DataSource = dt employees.DataBind() End If End Sub details table Protected Sub Page_Load( ByVal sender As Object , ByVal e As System.EventArgs) Handles Me .Load If Not IsPostBack Then bindformview1() End If End Sub Protected Sub FormView1_PageIndexChanging( ByVal sender As Object , ByVal e As FormViewPageEventArgs) FormView1.PageIndex = e.NewPageIndex bindformview1() End Sub Private Sub bindformview1() Try Dim constr As String = ConfigurationManager.ConnectionStrings( "Data Source=zoom-pc;Initial Catalog=HR;Integrated Security=True" ).ConnectionString Dim con As New SqlConnection(constr) Dim cmd As New SqlCommand( "SELECT * FROM Esalary WHERE EID= '" + Request.QueryString( "EID" ) + "'" , con) Dim sda As New SqlDataAdapter(cmd) Dim dt As New DataTable() sda.Fill(dt) FormView1.DataSource = dt FormView1.DataBind() Catch ex As Exception End Try End Sub
