Hi,

I'm developing a module that shows a list of contacts and has partial rendering enabled. To display the e-mail i use the DNN API function formatEmail.

When a postback occurs (e.g go the next page), the script generated by formatEmail doesn't render the e-mail link.

Anybody know how to solve this ?

Thx in advance

I am always wary about replying to 4 year old posts however since this is the only forum topic I came across when searching for a solution to exactly the same problem building with and running on DNN 4.9 where the issue still occurs (maybe it's fixed in DNN 5 or 6 I don't know) 
... well here goes. 

<script> document.writeto String.fromCharCode('10','19', ..... etc .... '90'); </script>

Javascript (etc) from the initial post is not recalled when a postback returns when using partial rendering. Neither is directly written scripts returned in the postback response - presumably something to do with the various Script Manager onLoad etc calls not parsing the HTML for scripts.

To make a script run explicitly on a postback you need to invoke the RegisterStartupScript method of the ScriptManager.

DNN 4 AJAX framework doesn't explicitly expose this script manager method but it is very easy to create your own ... along the lines of the following in a global class (see MyAJAX.RegisterStartupScript method in the class at the bottom)

Now we take the FormatEmail response and strip it down to the String.fromCharCode( ....) bit and register a startup script setInnerHTML that puts the String.fromCharCode(...) part into the innerHTML of the (in my case Label) control (see MyAJAX.FixFormedStringCodeScript method in the class at the bottom)

The javascript is quite basic then and I've included it just above the MyAJAX class below

What happens now is that instead of actually writing to the document directly via a script, the ScriptManager inherently dumps a pile of script calls (however many emails on screen) to setInnerHTML in it's own header on the page which are run on every postback so the email is correctly displayed during partial rendering.

Hopefully an fairly elegant solution to the problem - though no doubt someone will tell me otherwise :)

function setInnerHTML(sCtlID, sStringCode)
{
    var cCtl = dnn.dom.getById(sCtlID);
    if (cCtl!=null)
    {
        cCtl.innerHTML = sStringCode;
    }
}
