programmatically created buttons click event handler not working in updatepanel

i have a hovermenuextender with Target Control - an updatepanel, PopupControl - a panel with button named edit.

when i press edit, a textbox, and a button are created programmatically and placed inside the updatepanel.

the button's click event has a handler (added programmatically) which shud replace the text in updatepanel with the text in textbox, but this is not working - here's the snippet:

1protected void OrseButton_Click(object sender, EventArgs e)2 {3 OrseUpdatePanel.ContentTemplateContainer.Controls.Add(tbox);4 OrseUpdatePanel.ContentTemplateContainer.Controls.Add(savebtn);5 savebtn.Text ="Save";6 savebtn.Click +=new EventHandler(savebtn_Click);7 }89void savebtn_Click(object sender, EventArgs e)10 {11string temp;12 temp = tbox.Text;13 OrseUpdatePanel.ContentTemplateContainer.Controls.Clear();14 OrseUpdatePanel.ContentTemplateContainer.Controls.Add(new LiteralControl(temp));1516//throw new Exception("The method or operation is not implemented.");17 }

help me on this...i m using vs 2005, asp with ajax, c#

whats hapening is ur manipulating ur button and events at runtime, so when the page postback, the buton info and event is lost, what u need to to is save the whole thing to a viewstate, then on page call back u must recall this viewstate and reassign it to the button.

savebtn.Text ="Save";
savebtn.Click +=new EventHandler(savebtn_Click);

ViewsState["btn"] = savebtn;

On ur callback

savebtn = (button)ViewsState["btn"]

Hope this helps

i placed :

savebtn = (button)ViewsState["btn"]

in savebtn_click method.

now when i run it, it gives error serializing value 'system.web.ui.webcontrols.button' of type 'system.web.ui.webcontrols.button'

ok, on each callback recreate the event for ur button, coz when creating event at runtime, and when there'sa postback or callback, the event is lost, so have to recreate it and Once created ASP.Net directly rebind it.

can i have some example code...i wanna make sure i got u completely.
