Io voglio inserire in una pagina aspx, la ricerca di google e questo è il codice che mi genera google quando faccio la richiesta:
<!-- Search Google -->
<center>
<form method="get" action="http://www.google.it/custom" target="_top">
<table bgcolor="#ffffff">
<tr><td nowrap="nowrap" valign="top" align="left" height="32">
<img src="http://www.google.com/logos/Logo_25wht.gif" border="0" alt="Google" align="middle"></img><label for="sbi" style="display: none">Inserisci i termini di ricerca</label>
<input type="text" name="q" size="31" maxlength="255" value="" id="sbi"></input>
<label for="sbb" style="display: none">Invia modulo di ricerca</label>
<input type="submit" name="sa" value="Cerca" id="sbb"></input>
<input type="hidden" name="client" value="pub-3214921090532213"></input>
<input type="hidden" name="forid" value="1"></input>
<input type="hidden" name="ie" value="ISO-8859-1"></input>
<input type="hidden" name="oe" value="ISO-8859-1"></input>
<input type="hidden" name="cof" value="GALT:#008000;GL:1;DIV:#336699;VLC:663399;AH:center;BGC:FFFFFF;LBGC:336699;ALC:0000FF;LC:0000FF;T:000000;GFNT:0000FF;GIMP:0000FF;FORID:1"></input>
<input type="hidden" name="hl" value="it"></input>
</td></tr></table>
</form>
</center>
<!-- Search Google -->
Adesso questo scrip me lo visualizza senza senza problemi, ma quando vedo a fare una ricerca la pagina mi dà questo errore:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Che cosa comporta questo errore?
