is it possible to use Ajax with ASP.NET MVC 2 to reload a user control, pass along a new Model and have it update all the values that make use of this model without refreshing the rest of the site content?
View 2 RepliesI have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

View 3 RepliesIn a page I use prettyPhoto (a lightbox clone) that open a modal window showing an image when I click on a link with rel=prettyphoto. So I have:
<a href="fullresimage.png" rel="prettyPhoto">click here</a>
everytime I click on the link a postback is fired (IsPostBack = false). Can I avoid this? I have a counter on the page and everytime a pic is showed this is recognize as a full page load (i.e. increment counter) as IsPostBack = false!

I have a small issue with ModalPopupExtender. It opens in an Iframe initially, and shows the page: dd_contact.aspx After I have entered the contact details, the IFrame redirects to the contact_details.aspx page to show what I have loaded.The problem is when I close that modalpopup-window and click again to show the modalpopup, the iFrame shows the contact_details.aspx page, and not the add_contact.aspx page
View 3 RepliesI have a dashboard made of multiple webparts. One of the webpart is a usercontrol with a timer wrapped in UpdatePanel. When it is loaded in the dashboard I notice that it causes a Page_Load, and that triggers personalization procedures aspnet_PersonalizationAllUsers_GetPageSettings and aspnet_PersonalizationPerUser_GetPageSettings to fire.
Can can I avoid that? I read many posts on Timer controls within UpdatePanels, and it is my understanding that Timer would cause a full page postback, but only render the UpdatePanel that it is part of. However, these personalization functions execute every time Timer ticks.
I add cascading drop down in a place holder during page load. When i submit the entire form, i found out that my drop down list is reload and my selected value is not selected.
View 3 RepliesUsing VS2005, VB code behind, I have a page with two DropDownLists and corresponding CascadingDropDown's. I want to automatically postback when the second DropDownList index changes, therefore I have set its AutoPostBack="true". I have wired up the web services and the lists are getting populated as expected in IE7+, FireFox and Opera, but when I view the page in a WebKit based browsers (Chrome, Safari) the CascadingDropDown appear to load in an infinite loop. I included theWebkit compatibility fix but the issue persists. I've attached a working example below.Anyone know why Webkit browsers are infinitely reloading the cascading dropdownlists? Is there a fix?Source code below:Markup:

I have three cascading dropdowns and two of them need to trigger something outside of the dropdowns, so I have OnSelectedIndexChanged events on them. So as to not reload the whole page when these items are triggered, I have all of this in an Update Panel.
Everything works fine -- the only issue that the client doesn't like is that the cascading dropdowns reload on the asynchronous postback.
i thought of a textbox and a submit button,when submit button clicked comment extracted from textbox and saved into the database using sql.and displayed in literal.but all this is server sided,please help by providing example script for the following,please note i googled and googled but cannot find a satisfy easy and efficient answerOnMouseClickextract text from textbox saving it to a variable send the variable value to server instructing it to save the value in a db in a particular field of a particular table.simple words,facebooks comment box and the status updates box how are they implemented,thousands and thousands of them use it, still it doesnot get slow no postbacks observed to page reloading etc.
View 4 RepliesOn my website I have a lot of textboxes and radiobuttons. The user fills in his data and selections and then the information is written in a file by xml serialization. This all works fine. Now the requestor want the possibility to read the xml file and show the data on the page again for editting purposes. To read the file I use the Ajax AsyncFileUpload control. When it is finished uploading it fires the following event:

The ReadData sub is reading the data from the file and placing it in the controls. But then nothing happens. Th page is not reloading itself to show the data.
I am reading a tutorial article on this site about Partial Rendering using ScriptManager.EnablePartialRendering - [URL] The article uses button_click to demonstrate Partial Rendering without full page reload. I copy exactly the same codes but everytime I click the button the page refreshes.
I have examined after the page is loaded - ScriptManager1.EnablePartialRendering = true ScriptManager1.SupportsPartialRendering = true I am using vs2005 .NET 2.0 and AJAX extension 1.0 (same version as used in the article)
I know practically nothing about AJAX, but fully intended to utilize it in the future. Right now though I am noticing a behavior that may require that I implement it sooner then I planned.
I have been working on a fairily sophesticated web form that is made up of tables, dropdown lists, map buttons, and labels. As various controls are selected, specific tables are enabled or dropdowns/labels populated with information. All of this is working great, but when I put it all on a server and accessed it from a remote location, I noticed that every single action caused the entire page to reload.
From what I have read, it looks like AJAX and the UpdatePanel control will allow me to only refresh those areas that should be refreshed. Before I look further into implementing this, is this the only way to go? From what I have read on some other blogs, the UpdatePanel has some high performance costs.
I have an ASP.NET page with the following controls on it.
<asp:UpdatePanel ID="UpdatePanel3" UpdateMode="Conditional" runat="server">

I have dynamic ajax tabs that I want to load different usercontrols in each AjaxTabs.when Tab1 is created usercontrol1 loads in it.when Tab2 is created usercontrol2 loads in Tab2,but the problem is usercontrol1 does not remain in Tab1 when Tab2 is created and tab1 became empty.& When Tab3 is created, usercontrol2 does not remain in Tab2.I want to keep my usercontrols in my tabs,whenever I create a new Tab.
I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

This is page load
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{ [code]...
But in my ascx.cs when IButton1_Click is trigered My name is null
private string _sname;
protected void Page_Load(object sender, EventArgs e)

im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesI have a ajax tabpanel where i add the "tab content" dynamicly with use of iframe. In one of the iframes i have to add a user control (menu bar) to the page, but (ofcource) when i add the usercontrol it end up in the iframe from where it was added.Is there anyway to set the position outside the iframe?.
