Hi all,
I've got a Jquery UI dialog that pops up to confirm the creation of an item after filling out a form. I have the form in an update panel due to various needs of the form, and especially because I want validation being done on the form without reloading the page.
JavaScript appears to not reload on an asynchronoous postback. This means when the form is a success and I change the variable 'formSubmitPass' to true, it does not get passed to the Javascript via <%= formSubmitPass %>. If I add a trigger to the submit button to do a full postback, it works. However I don't want the submit button to do a full postback as I said so I can validate the form within the update panel.
How can I have this so my form validates asynchronously, but my javaScript will properly reload when the form is completed successfully and the item is saved to the database?
Javascript:
var formSubmitPass = '<%= formSubmitPass %>';
var redirectUrl = '<%= redirectUrl %>';
function pageLoad() {
$('#formPassBox').dialog({
autoOpen: false,
width: 400,
resizable: false,
modal: true,
draggable: false,
buttons: {
"Ok": function() {
window.location.href = redirectUrl;
}
},
open: function(event, ui) {
$(".ui-dialog-titlebar-close").hide();
var t = window.setTimeout("goToUrl()", 5000);
}
});
if(formSubmitPass == 'True')
{
$('#formPassBox').dialog({
autoOpen: true
});
}
So how can I force a postback from the code behind, or reload the JavaScript on an Asynchronous Postback, or do this in a way that will work such that I can continue to do Async form validation?
Edit: I change formSubmitPass at the very end of the code behind:
If errorCount = 0 Then
formSubmitPass = True
upForm.Update()
Else
formSubmitPass = False
End If
So on a full postback, the value does change.
