jQuery Confirm Dialog in ASP.NET Button OnClientClick - asp.net

Question

I have a TemplateField in a GridView in an UpdatePanel with a button called btnDelete. Rather than the standard OnClientClick="return confirm('Are you sure?')" I'd like to use jQuery Dialog.
So far, I'm able to set the jQuery using btnDelete.Attributes["onclick"] and setting the jQuery Dialog code in the code-behind. However, it posts back to the server in all cases before I have a chance to click "Confirm" or "Cancel".
Here is the HTML it produces:
<input type="submit" rel="Are you sure?" class="action-link delete" id="ctl00_c1_gvTransfers_ctl02_btnDelete" onclick="return function() {
$('#delete-transfer-confirm').dialog({
buttons: {
'Confirm' : function() { $(this).dialog('close'); return true; },
'Cancel' : function() { $(this).dialog('close'); return false; }
}
});
$('p.message').text($(this).attr('rel'));
$('#delete-transfer-confirm').dialog('open');
};" value="Delete" name="ctl00$c1$gvTransfers$ctl02$btnDelete">
What am I doing wrong that is causing this function not to block until either button is clicked?
Conversely, the standard confirm works just fine:
<input type="submit" class="action-link delete" id="ctl00_c1_gvTransfers_ctl02_btnDelete" onclick="try{if (!window.confirm('Are you sure?')){return false;};}catch(e1){alert("Unexpected Error:\n\n" + e1.toString());return false;};" value="Delete" name="ctl00$c1$gvTransfers$ctl02$btnDelete">
Thanks,
Mark
UPDATE:
Ultimately, I had to use UseSubmitBehavior="false" to get the name="" attribute to render. Then I had to override the OnClientClick, setting the value to "return;" so the default __doPostBack() doesn't get executed. Then I was able to wire up a .live() click handler, which invokes the __doPostBack() on Confirm:
$('input.delete').live('click', function(e) {
var btnDelete = $(this);
alert($(btnDelete).attr('name'));
e.preventDefault();
$('#delete-transfer-confirm').dialog({
buttons: {
'Confirm': function() {
$(this).dialog('close');
__doPostBack($(btnDelete).attr('name'), '');
return true;
},
'Cancel': function() {
$(this).dialog('close');
return false;
}
}
});
$('p.message').text($(this).attr('rel'));
$('#delete-transfer-confirm').dialog('open');
});

Check the selected answer for this question for an example: How to implement "confirmation" dialog in Jquery UI dialog?
A couple of notes:
Don't put your onclick functionality in an onclick attribute. One of the great benefits of jQuery is that it allows you to do Unobtrusive Javascript. Instead, do something like this:
$(function() {
$('.delete').click(function(e) {
e.preventDefault() //this will stop the automatic form submission
//your functionality here
});
});
Also, make sure that your dialog is instantiated outside the click event, so that it is initialized before the first click event happens. So, something like this would be your result:
$(function() {
$("#delete-transfer-confirm").dialog({
autoOpen: false,
modal: true
});
$('.delete').click(function(e) {
e.preventDefault();
$('#delete-transfer-confirm').dialog({
buttons: {
'Confirm': function() {
$(this).dialog('close');
return true;
},
'Cancel': function() {
$(this).dialog('close');
return false;
}
}
});
$('p.message').text($(this).attr('rel'));
$('#delete-transfer-confirm').dialog('open');
});
});
That should do the trick for you.

$(document).ready(function () {
$('#btnCancel').click(function (e) {
e.preventDefault();
$("<div><span><b>Are you sure you want to cancel this order?</b></span></div>").dialog({
modal: true,
draggable: false,
resizable: false,
width: 430,
height: 150,
buttons: {
"No": function () {
$(this).dialog("destroy");
},
"Yes": function () {
$("#btnCancel").unbind();
$(this).dialog("destroy");
document.getElementById('<%= btnCancel.ClientID %>').click();
}
}
});
});
});
Then in the Page Body
<asp:button id="btnCancel" runat="server" cssclass="button_major" text="Cancel" style="float: right"
onclick="btnCancel_ClickEvent" clientidmode="Static" />
