Handlers and dynamic buttons

[noone]

Below are the guts to a function that returns a textbox and button. A
handler is added to the button. All this is done in a class separate from
the code behind including the Handler.

So here is the problem, unless I regenerate the buttons, when I post back
the handler for the button pressed does not fire. What do I need to do to
make this handler work?

Dim p As New PlaceHolder
Dim btn As New ImageButton
Dim txt As New TextBox
txt.Text = "1"
txt.ID = "txt" & Detail.Asin

txt.Width = Unit.Pixel(20) '
txt.EnableViewState = True

btn.CommandArgument = Detail.Asin

btn.ImageUrl = "amzImages/add-to-cart-02.gif"

btn.ID = "btn" & Detail.Asin

btn.EnableViewState = True

AddHandler btn.Click, AddressOf Purchase_AddToCart

p.Controls.Add(btn)

p.Controls.Add(New Web.UI.LiteralControl("<br>Qty: "))

p.Controls.Add(txt)

p.Controls.Add(New Web.UI.LiteralControl("&nbsp"))

Return p

Hi,

If I get you right, you must recreate and attach events to dynamically
added controls every time page is loaded including post backs.
