I'm using
__doPostBack(clientIdOfSomeButton, someData);
to create a PostBack in JavaScript. The problem is that someData
is not known in advance, and event validation kicks in because I cannot ClientScript.RegisterForEventValidation
every possible value of someData
.
So far, I can see only two possibilities to solve this problem:
__doPostBack
. That's ugly.Is there some third option that I've missed? Ideally, I'd like something like ClientScript.RegisterForEventValidationIgnoreArguments(myButton)
, but something like this does not exist...
If someData is not known in advance then how does the server know the meaning of the postback? The second argument is to indicate the type of event or specific information concerning the event, not a user inputted value.
I would register for a custom argument and pass the someData another way.
ClientScript.RegisterForEventValidation(clientIdOfSomeButton, "CustomEvent");
And on the client
Html
<input name="customArgument" type="hidden" value="" />
Javascript
document.forms[0].customArgument = someData;
__doPostBack(clientIdOfSomeButton, '');
then retrieve your value
if(Request["__EVENTARGUMENT"] == "customArgument")
{
var customArgument = Request["customArgument"]
}
