View 3 RepliesI have a panelA with a drop down list (ddl1) and a panelB with 2 dropdown lists (ddl2 and ddl3).
I am disabling PanelB in the page_Load section. When a selection has been made in the ddl1 in panelA, I am enabling panelB in OnSelectedIndexChanged event to enable ddl2 and ddl3.
This process is working, but as soon as I make a selection on ddl1, the whole page reloads to enable ddl2 and ddl3, which feels odd. How can I make it just reload panel3 not the whole page? I guess it can be done using AJAX update panel but as soon as I put <%@ Register Assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxtoolkit" %> and <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>, I start getting wierd error: Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'Object' cannot be converted to type 'Array'.

In 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!

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.

View 2 RepliesI 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'm trying to work on this page that requires me to have a hyperlink/button that, when clicked, should duplicate a section of a page which includes several text fields, radio buttons, a dynamic table (where the user can add rows and edit fields), and the actual link itself. Is this possible? If so, could someone please show me how? :( I'm really stumped on how to do this one.
View 2 RepliesI've built a page which has an update form, and above that, a photo (based on the same edit). The photo is loaded based on the selected table row being edited.
On this page, I've got a button that opens a modal in an iFrame and allows the user to update just their profile image (all works fine). But when the modal is closed, I'd like to reload JUST the photo (and not the entire page), as it will have changed.
How should I go about doing this? I assume I'll need to use some Ajax controls?
i have a website that has html tables <tr></tr> tags. I have problems with refreshing my page. When the select a radiobutton of a list, there should apear a other control. But that only happens when i refresh the page my clicking on a button. So i thought of using ajax.
View 1 RepliesGot some small(Basic) doubt on update panel. Using Update Panel, Is it possible to stop updating a part of Page ?
The problem is, I have a very small portion of page, in which I'm updating some data using JavaScript, Which I want to retain(in ASP language Maintain State) for any post back that will occur in Page. I thought placing update panel will solve the purpose, But as per Update panel principle, It will updates only that part of page based on the Triggers conditions.
I want it exactly in reverse way (It is very difficult for me to place Update panel for the entire page excluding the small part).
I have a page that is based on my master page. the code below
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="CaseAdmin.aspx.cs" Inherits="Prototype4.CaseAdmin" %>
<%@PreviousPageType VirtualPath="~/Account/Login.aspx"%>[code]....
when the page above loads, i have link buttons on the left and an empty maincontent area next to its right. what i want to do is display an entry form in the main content on click event of the link button on the left. the second form is as below.(form not based on master page).
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="OpenCase.aspx.cs" Inherits="Prototype4.EntryForms.OpenCase" %>
<%@PreviousPageType VirtualPath="~/CaseAdmin.aspx" %>[code]....
how do i perform this task and if i wanted to display a different form in place of the first one that appeared in the maincontent area, how do i go about it?

View 2 RepliesI 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.

View 3 RepliesI am creating a custom cookie and have overloaded the Iprincipal class and all that good stuff. My cookie works correctly and I am able to retrieve the roles of the users successfully, but the admins have to reload the default page after just logging in to see the admin only button. Once they visit a new page on my site and return to the default page, the button is there.
I read somewhere that the cookie is created last and has something to do with a response to the HTTP. TBH, I am new to this stuff and don't understand exactly how that works, but I see how it effects my program. I am currently creating and planting my cookie in the page load of my default page. Should I be doing it somewhere else, perhaps in the log-in page? I tried that, but the same issue still exists. Am I missing something?

I use VS 2008 and C#, asp.net
I need to reload page after button click.
I have tried following
[code]....
it did not work.
The reason i need to reload page is that in the page load im creating cookie. THis cookie helps me to avoid 1 messagebox every time i load page it loads only the first time.
but the problem is that when the page is loaded it will not disappear when i use other widgets on the page.
but when i go to another site and i go back then it works. So i clearly need something to clear the cache or reload.
