<asp:Button ID="btn" OnClientClick="if(confirm_delete()){
/* post back*/
}else{
return false;

I have this code but I cant do postback for it, im not sure how to?
is it:
<script type="text/javascript">
function CallServer() {
__doPostBack('not sure what goes here','or here');
}
</script>

I have a simple asp:RadioButtonList within a form tag but for some reason it isn't keeping it's value on postback
Here's what I've got
[code]....
all elements are in an updatepanel. click on a list of <tr> to fire a JavaScript function to add new <option> to the asp dropdownlist. But, when I click on other buttons to callback to the server, I get an error message:
Uncaught
Sys.WebForms.PageRequestManagerServerErrorException:
Sys.WebForms.PageRequestManagerServerErrorException:
Invalid postback or callback argument.
Event validation is enabled using
in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I understand the problem. I need to let server side know the change of the dropdownlist before any other postback. Set validation as false won't work in this case, the dropdown will lose the new item anyway. I did some researches, and the possible solutions:
1)Using ViewState? Request Form? could anyone give an example?
2)Add dropdownlist item in server side. But I want to make the whole tr row clickable to fire the event. Could I click on tr and fire eg. its first child linkbutton or a linkbutton in somewhere else.
3)I've tried Jquery.ajax and webmethod , it can fire server event but since all method are static (shared) , it doesn't allow me to edit the downdownlist instance.
I have a linkbutton to which i am binding to the click event using jQuery, however the page still posts back no matter what i try...
According to this i should be able to use event.preventDefault However nothing seems to work and it always posts back, but i do get the alert
Here is my example
<asp:LinkButton runat="server" Text="TEST" ID="lnkTest"></asp:LinkButton>
<script>
$(document).ready(function () {
var lnk = $('#<%=this.lnkTest.ClientID %>');
lnk.unbind('click.test').bind('click.test', function (event) { alert("Click"); event.preventDefault(); event.stopPropagation(); return false; });
});
</script>
UPDATE
Okay after some further investigation it seems that this does work as expected when i run it in a standalone page, however we are using this script, and it appears that it is causing a conflict..
That script moves any href='javascript:... into the click handler, im guessing that the order the handlers are assigned may have something to do with it...

postback in 2 using jQuery dialog UI?

I have an asp.net page with some JQuery tabs. Everything works ok.I added a dropdownlist in one of the tabs, that causes a postback. After the postback I want the same tab to be selected.I initialize the tabs as:
<script type="text/javascript">
$(document).ready(function() {
var $myTabs = $(".tabsDiv").tabs();
</script>
Then, on the PageLoad event, I inject a script to select the tab:
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "TabSelect", "$myTabs.tabs('select', 1);", true);
For some reason this doesn't work. The script is running but the tabs are not selected.Is it because the RegisterClientScriptBlock places the script in the bottom of the page and, for some reason, it runs too late?

View 8 RepliesI have custom control with ASP.Net validators.
writer.AddAttribute(HtmlTextWriterAttribute.Onclick, "javascript:return DoSmth();");
function DoSmth() {
var cBox = confirm("Are you sure?");
if (!cBox) {
return false;
}
else {
//Invoke validation

When I push button submit, I call confirm box. If I press cancel - all right. But if I press ok, I need to do validation. How can I stop postback and do valiadation?
I couldn't find something similar in SO.
In ASP.NET, is there any way that on cue I can cause a partial postback with Javascript in an UpdatePanel?
I tried __doPostBack() but it does a full postback. I can trick it with a dummy button and fire click() then handle the partial postback that way, but I want a more graceful way than trickery.
actually this code is working well in firfox mozila but it's not working in IE8

I have an ASP.NET checkbox, and I want to run some javascript before it posts back.
Something like:
<asp:CheckBox ID="chkSelected" runat="server" AutoPostBack="True" OnCheckedChanged="chkSelected_CheckedChanged" />
but I want to run a JS confirm dialog when the user click it, and if they were UNCHECKING it, I'd like to ask them if they're sure, and if so, postback and run my serverside code. If they say No, don't postback at all.
Ive got on my aspx page button with code:
OnClick="save_Click"
Is it possible to execute javascipt before postback and if result is true then do postback and go to method save_click and if not just ignore it ?
Here is my scenario:
I have user controls within a master page and within a user control, I may have an update panel. I have the following bit of code I place within a usercontrol that maintains various control styling during partial postback i.e. those controls affected within by an asp update panel.
function pageLoad(sender, args) {
if (args.get_isPartialLoad()) {
$("select, span, input").uniform();
Indeed, when an update panel does its thing, the Fancy Dan styling is maintained. However, I have one gripe - when a 'large' partial postback occurs, occassionally you'll see the default, generic control styling reappear breifly and then the uniform kicks in to reapply the new fancy styles. Is there any way I can avoid seeing the nasty old, default, bland stylings?
What's a good way to show an jquery ui dialog on postback ?
1. Create the whole div in on the server and populate an asp literal control and fire the required javascript (but when).
2. Use hidden fields for your values inside the div, fire the required javascript (but when).
3. Someone has another viable solution for me ?
I have a JQuery Dialog that is opened when a button is clicked. The first time around, it should do a postback, but when the dialog closes and I click the refresh button of the broswer, it sends the data again and duplicates the data I just entered. Should I add a return false somewhere so it doesn't postback when the dialog is closed. Here is the script:
