AJAX :: Page Is Posting Back On Server - Works Ok In Development?
Jan 9, 2011
Got a pretty simple page where i want an update panel to become visible or hidden based on a button click. When i run this page in VS2010 in debug mode it works as i expected it to - page does not post back, the panel just appears or disappears on the page without the whole page refreshing.
I uploaded this to my server, and the page is posting back when you click the button.
Server is win2k8R2 x64 IIs7.5
Do i need to enable anything in the IIS configuration?
have a Visual Studio 2010 project which targets v4.0 of the .NET framework.In the project, I have a page with an ASP.NET UpdatePanel - which works perfectly within VS2010's development server.However, when deployed to an IIS 6 server, the controls in the UpdatePanel cause a full-page postback - not an async postback.The site has its own application pool.I've tried visiting the ScriptResource.axd URLs which are present in the rendered page and they all produce valid looking JavaScript files.I can't see any Javascript or other errors.
when any Button control is clicked generally it Postback the page to itself, and the same page is regenerated.This is the usual defination of postback in context of a Button Control. But my dear friends i am confused that what is the actual mechanism behind this.Okey say for definition the above statement is fine but believe me i not not getting the actual meaning.What is posting back the Page? What is Page in browser's context? There is only html markup, JavaScript and CSS codes in browser's page.These make up the html page. I think there is no any relation of this Browser's page with ASP.NET Page class. What does it mean that browser's content is posted back to the Page itself ?
I have a control which inherits from LinkButton and I'm trying to make sure that the user cannot cause mayhem by performing multiple postbacks. That seemed an easy enough challenge, so I have this code [snippet] on the client:
[Code]....
The alert is of course only there for debugging. If the DisableOnClick value is false, then I see the "Posting Back" alert and, when I click ok, the postback occurs - all good.
If the DisableOnClick value is true, then the "button" gets disabled and the cursor turns into an hourglass - again good. But the postback doesn't happen - not good. I assume that the ASP client code is trying to preventing the postback when it sees that the link is disabled.
So, how can I either:
Persuade the LinkButton to postback even though it has just been disabled; or[probably better] Get my client code to execute immediately after the postback code rather than before.
I have a problem of posting back in my website in some browsers. The Problem is: When I am uploading a file using file upload and button or posting page back on some event click after button click I am using:
Anyone knows how to do this? I have three distinct updatepanels on my page, and they're all unrelated. If possible, I would like the user to be able to interact with the other updatepanels while one is refreshing, or at least show which one is refreshing by only covering this with a div+animated gif.
I have a web application in ASP.NET 4.0. I've added an asmx service, primarily as a source for the autocomplete extender's lookup values.
When I debug on my machine locally, everything works fine. However, when I deploy the web application to IIS 7.5, I get a HTTP 404 response when trying to send data to the service.
I am able to browse to the service definition, see the available operations. Tellingly, however, when I use the test pages to test the service using POST, I receive an HTTP 404 again.
I'm not sure what is going on. I did create the asmx file within my web application and it is deployed in the virtual directory of my otherwise working production application. Is there an issue with the .asmx file being deployed in the same virtual directory, perhaps?
in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value.
The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it.
How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked?
I have a button on my web form. When it is pressed, the event method for that button is called as it should be. However before the buttons method is called, the page load event is first called. Is there a way to prevent the page load event from being called when the button is pressed? I know about using !Page.IsPostback in the Page load method. However I wish to avoid posting back to the Page Load method altogether when this particular button is pressed.
I basically want to show a dialog box with confirm or cancel options on it.
Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.
$('#buttonInUpdatePanel').live('click', function (event) { event.preventDefault(); var item = this; var title = 'Confirm'; var msg = 'Please confirm something'; var $dialog = $("<div id='myDialog'></div>") .html(msg) .dialog({ modal: true, buttons: { "Confirm": function () { $(this).dialog("close"); __doPostBack('Button1', null); //tried this and .submit() on the button //return true; }, "Cancel": function () { $(this).dialog("close"); //return false; } }, title: title }); });
I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.
I am trying to get a functionality where on a click event a popup comes up. And on this pop up there are controls like a text box,a button and a grid which can speak back and forth with the server. Also I need to get values from the grid when the pop up is destroyed.
I am currently using JQuery to post to action methods in my MVC app. The methods are quite complicated and since I only know the basics of Javascript and JQuery, if I wanted to use JQuery to make a client side call, would I be able to make a call to a web service to do this? I am new to all these technologies so not sure about how posting from JQuery to web services etc works.
I am trying to implement autocomplete using JQuery. I cannot get this to work directly from my view so I am trying to post directly back to a method in my controller that has a reference to the web service. How do I post directly back to a method in my controller?
My method name is Autocomplete URL: "/" - Takes me to the Index method of my main controller. I want to go to a different method so I can return JSON back
I have a keyboard-controlled menu which I did with jquery (When I press down, it marks second option and so on...)
But after I select the option I need, I want to click enter to call the button's OnClick method as if the user really clicked it. Which means I have to do a postback.
i have the below page and i am racking my brain as to why when i have two update panels do they both get post backs. i can tell cause i have two user controls- one in each panel and they both fire page load events when only the left panel should be posing back and updating itself... or else whats the point of update panels if in reality the entire page is posting back!
I'm using ASP.NET MVC to try to postback after confirmation using javascript, this is the button:
<input type="submit" id ="RemoveStatus" value="Remove Status" name="button" onclick="return CheckRemove();"/>
This is my javascript in my CheckRemove() js function:
var button1 = document.getElementById("RemoveStatus"); if (confirm("Are you sure you want to remove status?") == true) { button1.disabled = true; button1.value = "Removing status..."; __doPostBack('RemoveStatus', ''); return true; } else { return false; }
But for some reason I get an object expected error at the __doPostBack bit, I've clearly set the id, button1 gets populated too in debug, i'v tried passing button1.id and button1 too into the __doPostBack call but it wont postback and keeps saying object expected.
