RE: [aspx_professional] RE: emphyrioHi,

(pardon my bad English)

You are right.

I tried some hours and the only solution seems to be call createForm 
during the postback in form_load event:
so...
Sub Page_Load(....)
    If Page.IsPostback then
      'At this time btnSubmit doesn't exist   
      createForm(...)
      'Here btnSubmit exists and the event fires
   End if
End Sub

  That's too funny that you sent that link, I've just been working from 
that for the past hour or so but can't seem to get it to function.  The 
only way I get it to work is if I add the control to the form from the 
page load event.  If I try to dynamically add the control from a button 
click onto my panel then when I click on it all the controls disappear 
and nothing happens.  Does anyone see what's wrong below?  It renders 
all the controls from a configuration stored in a datatable perfectly 
(with the exception being a unique case where I get a cast error) but 
when I click on the button the handler that I added doesn't fire.  Any 
help is greatly appreciated!

      Private Sub createForm(ByVal dtFormProps As DataTable)

          Try
              Dim dr As DataRow
              Dim lblCustom As Label
              Dim tbCustom As TextBox
              Dim btnSubmit As Button

              For Each dr In dtFormProps.Rows

                  lblCustom =3D New Label()
                  With lblCustom

                      .ID =3D dr("FieldName") & "_Label"
                      .Text =3D dr("InputLabel")

                  End With

                  Select Case dr("InputType")

                      Case "textbox"
                          tbCustom =3D New TextBox()

                          With tbCustom

                              .MaxLength =3D dr("dbFieldMax")
                              .ID =3D dr("FieldName")

                          End With

                  End Select

                  
Page.FindControl("pnlLoanTypes").Controls.Add(lblCustom)
                  
Page.FindControl("pnlLoanTypes").Controls.Add(tbCustom)

              Next

              btnSubmit =3D New Button()
              With (btnSubmit)
                  .ID =3D "btnAddItem"
                  .Text =3D "Add Item"
              End With
              Me.FindControl("pnlLoanTypes").Controls.Add(btnSubmit)
              AddHandler btnSubmit.Click, AddressOf Me.btnSubmit_Click

          Catch ex As Exception

              Response.Write(ex.Message.ToString)

          Finally

          End Try

      End Sub



      Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e 
As System.EventArgs)

                  Response.write("YOU CLICKED THE BUTTON")

      End Sub

  >Alessandro,

     Thanks so much. I looked up the addhandler method on the net and
  immediately found this article:

    I will try this technique tomorrow!
