Place this in your child page
<%@ MasterType VirtualPath="~/MasterPage.master" %>
and call the function as you have done.

Because you are adding textbox in the click event of Add button.
So when u click save button you are not getting anything

You will not get. Because you have to create the textbox, before Page_Load(), because Postback data and view state data load for control before page_load. Create your control on Page_PreInit() will resolve your problem.

Create a HashTable and add the control id as key and control value as value.
Then at postback get the control's value using Request.Form(control_id) and create the control again and assign it the same value.

Example :

      Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

            Try

                  If Not IsNothing(ViewState("ht")) Then

                        Dim v_ht As New Hashtable
                        v_ht = CType(ViewState("ht"), Hashtable)

                        For i As Integer = 0 To v_ht.Count - 1
                              'getting value of 1st control
                              Dim a = Request.Form("txt_1")
                              'getting value of 2nd control
                              Dim b = Request.Form("txt_2")
                        Next

                  Else

                        Dim ht As New Hashtable

                        'dynamically created 1st control
                        Dim txt As TextBox
                        txt = New TextBox
                        txt.ID = "txt_1"
                        txt.Text = "CODE"
                        ht.Add(txt.ID, txt.Text)
                        ph_Main.Controls.Add(txt)

                        'dynamically created 2nd control
                        txt = New TextBox
                        txt.ID = "txt_2"
                        txt.Text = "PROJECT"
                        ht.Add(txt.ID, txt.Text)
                        ViewState("ht") = ht

                        ph_Main.Controls.Add(txt)

                  End If

            Catch ex As Exception
                  Response.Write(ex.ToString)
            End Try

      End Sub

store the id(s) of dynamic controls in a hashtable.
at postback loop through the hashtable and using Request.Form and passing control id through hastabale , get back all values.

this is the easiest method of getting back the values of dynamically created controls.

Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSave.Click

TextBox txtBxTemp = (TextBox)e.Item.FindControl("tx");
Label1.Text = txtBxTemp.Text;

End Sub

Well those two list are C# I have no clue what VB would be maybe:
txtBxTemp as TextBox = (TextBox)e.Item.FindControl("tx") ?

Just render one HTML and place it into your div.

Mind that, you need to specify the name attribute of the dynamically created controls, as you can get the name from the Request.Params I think. Rose | [Rose]

Don't you think, it is obvious. You are calling the Onload event from Load method. It is a recursive loop. OMG | :OMG:

You want the rendered HTML output of the panel, right? Try something like

public string GetControlRenderedOutput(Control control)
{
    StringBuilder builder = new StringBuilder();
    StringWriter writer = new StringWriter(builder);
    HtmlTextWriter htmlWriter = new HtmlTextWriter(writer);
    control.RenderControl(htmlWriter);
    return builder.ToString();
}

Try passing your panel's object to this method.
