fnDrawCallback: How to display a message on callback?

mvelasquez

I'm using server side to load my data, however, BASED on the count of data I'd like to display a message back to the user.

In the sAjaxSource logic I'm able to set ViewState to let me know that I need to display the message, but I don't think this is accessible in the fnDrawCallback function.

I'm attempting to retrieve a hidden field's value in the fnDrawCallback function but the value, after setting it in the ViewState of the sAjaxSource logic, is empty.

here's my code:

[code]"fnDrawCallback": function(value) {

var show = $('#ShowMessage').val(); //accessing hidden field

if (show && show === "true") {

var message = document.createElement('div');

message.innerHTML = '' + $('#RetrievalMessage').val() + ''; //RetrievalMessage is hidden field that holds text of message

$('#vendorItems_wrapper').prepend(message); //place message at top of datatables grid

}
}[/code]

Now again, "ShowMessage" and "RetrievalMessage" are hidden fields tied to ViewState.
I'm setting the ViewState in the sAjaxSource, but it's not being updated once I get into fnDrawCallback.
Is there another way to send this "RetrievalMessage" text through to fnDrawCallback?
Perhaps through the "value" event argument of fnDrawCallback's function?
