LinkButton does not POST

[Oscar Thornell]

Hi,

Problem: LinkButton control does not POST
Environment: Win 20003, ASP.NET 2.0, XHTML
Target/device: Symbian v.9/Opera 8.60 (168) based smartphones

I am developing a mobile web application (VS.NET 2005/xhtml) the target
device(s) are Symbian (v.9) based smartphones. We recently recived a new
"batch" of test devices with upgraded software..

For months now the Link Button with code like this: "<a
id="ctl00_mainContent_btnLogin" class="link"
href="javascript:__doPostBack('ctl00$mainContent$btnLogin','')">Login</a>"
have worked...

Unfortunately that is no longer the case and the browser in the device(s)
don't POST when clicking the links...

The LinkButton control does not trigger a POST in .NET 2.0. If the same code
is recompiled and run under .NET 1.1 everything works.
The cause of the problem is probably the generated Javascript method
"__doPostBack"


//.NET 1.1 (Here everything works..)
<a id="LinkButton1"
href="javascript:__doPostBack('LinkButton1','')">LinkButton</a>

<!--
function __doPostBack(eventTarget, eventArgument) {
var theform;
if (window.navigator.appName.toLowerCase().indexOf("microsoft") > -1) {
theform = document.Form1;
}
else {
theform = document.forms["Form1"];
}
theform.__EVENTTARGET.value = eventTarget.split("$").join(":");
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}
// -->



//.NET 2.0 (Does not work..)
<a id="ctl00_mainContent_LinkButton1"
href="javascript:__doPostBack('ctl00$mainContent$LinkButton1','')">LinkButton</a>

<!--
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
// -->



Have anyone a solution?

Regards

I had the same problem. One question in my mind was why it is not going to Event. could be something stopping the page from postback. Could be some validation control. So I added CaussessValidation property to false. Boom it worked for me. Try this probably works for you.
