I'm following this example: [URL]
And I can get it to work with just a single page and a code behind, but when I add a masterpage, the examples doesn't work properly. Within my master page, I have a head content section and a body content section. It's nothing fancy.
How do i do client callbacks with master pages?
Apropos MSDN link: [URL] [.NET Framework 4 - ASP.NET] Implementing Client Callbacks Programmatically Without Postbacks in ASP.NET Web Pages Using the code from the above link in the following code snippet, if you keep a break point on the statement "if (IsPostBack)" in the Page_Load event. The control moves into the "if (IsPostBack)" block after the alert, which mean that it is a Postback. Then, how come you say "...Without Postbacks"? I am getting confused here.

just wanted to know how to fetch client ID of controls in child pages in master page layout? Trying to use but no avail
$addHandler($get('<%=btnSavLay.ClientID%>'), 'click', function() {
$('#Layers').block({ message: null });

It always throws Sys.ArgumentNullException: Value cannot be null. Parameter name: element [Break on this error] {name: "handler", type: Function}
i'm developing a site using VS2010 and with my windows vista busniness OS. i used the default VS2010 wizard for new web application to create it. included a folder in the root directory and created new aspx pages to derive from the master page in the root directory of my site. everything shows on the new pages except the jpeg image logo in the master page. But other aspx pages i created in the root directory shows every thing fine.
View 1 RepliesCurrently I'm doing common functionality required throughout my site inside of my masterpage. What I want to do is move this functionality to a BaseClass so All my pages inherit from the Base Class. However, I'm not sure how to set this up interms of c# code with regards to Using a Base Class and then having a masterpage applied to my aspx pages that i create.

How do you implement SquishIt to bundle Css/Js across View Pages and Render it in the Master page? I thought I could use a ContentPlaceHolder above the Render portion, but there seems to be some odd behavior where it sometimes adds 3 files (1 in the view page and 2 in the master page) but other times will ignore the file added from the View Page.
Index.aspx
<asp:Content ContentPlaceHolderID="CssFiles" runat="server">
<% CssHelper.Add("home.css"); %>
</asp:Content>
Site.master
<asp:ContentPlaceHolder ID="CssFiles" runat="server" />
<% CssHelper.Add("reset.css"); %>
<% CssHelper.Add("master.css"); %>
<%=CssHelper.Render() %>
My current solution is a Static wrapper around SquishIt's static Bundle class that keeps the BundleBuilder in HttpContext.Current.Items.
I'm curious if this has been done successfully and how so.
Is it possible with ASP.NET Master Pages to create content pages dynamically?That is, I know we can create content dynamically, but the content pages themselves,can those be created programmatically? I want to give my users the ability to define new content pages (i.e. Categories: Sofas, Tables, Lamps, and add/delete as they see fit) through a management panel. The resulting content pages should have proper URL naming, so that they index properly.An example: http://www.example.com/products/Lamps/contentpage.aspx.Is there a demonstration of this somewhere I can view?

Top Level Master page
Second Level Master page inherited Top Level Master page

However, changes (i.e. new images & alt. name) that I made in the Top level master page did not apply to the second or third levels.My webpage has a correct front page but not in the sections. How can i correct this ?

View 3 RepliesI have over 300 content pages to create. Each has some standard styling. I would like to generate these pages, and was just wondering if there is a utility in web developer 2008 express to do so (otherwise I will just build one - but it would be great not having to do so!)
View 1 RepliesI have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?
View 4 RepliesI have a main master page, say MasterPageMain, and a couple of folders with couple of pages in each folder which act as a child page to that master page - MasterPageMain.
Now, I have about 10 pages in one of the folder which follows a certain pattern and they could really use a nested pages since any change on some parts needs me to change all the pages which is a pain really.
I already added a Nested master page, say NestedMasterPage - which is a child of MasterPageMain
I tried to change one of the page's <%@ Page directive to NestedMasterPage, immediately, there were a lot of errors. plus I dint know where the NestedMasterPage's children content would go.
What do I need to know in order to do this succesfully?
ps: I dint do this initially because I only had 2 pages, and I dint need this at that time, as the project grew, now i see that I should have changed it much earlier..
I'm using a third party control which fires a server side method when a document gets saved. Should there be any problems with saving, I'd like to display a message on the client side, such as:
[Code]....
Doing that in server side doesn't work after discovering IsCallBack = true.
How do you update lblMessage via CallBack without a full PostBack?
I am using a third party UI Library (devexpress) to implement some data grids. These grids work with Callbacks (not UpdatePanel partial Postbacks).
I am trying to use Scriptmanager RegisterStartupScript to execute some code on the client after the callback. This works great with partial postbacks but does not work with Callbacks.
Is there any way to queue client side code for execution inside the callback server side handler?
I'm using jquery for validation in my MVC2 web app (as described here) and I'd like to wire up some callbacks that the jquery validation plugin supports, like invalidHandler, etc.
I can manually edit the MicrosoftMvcJQueryValidation.js and add my callbacks (in __MVC_EnableClientValidation, in the options variable) but I was looking for a better approach since that file is used repeatedly and I don't want to have to create one-off copies.
A way to manually add an invalidHandler (etc) callback to the form validation, would be exactly what I need. Obviously this would normally be done via the options when calling validate() for the first time, but since Microsoft controls that particular part, that isnt an option.

View 2 RepliesUsing MVC 2 for what it matter. (And also keep in mind for some reason I NEVER used Nested Master Pages)
I got a single Master page that work across my site.
However, I found from the design now, that each "Area" have a different subnavigation.
Figured it might finally be a reason to use Nested Master Pages....resulting into a lot of swearing over here...
What I did:Add a "Nested Master Page" to the "Shared" folder of a specific Area
(project/Areas/xxxx/Views/Shared/NestedMasterPage.Master)VS bring up a box asking to specify a Master Page, and I select the only one i have (project/Views/Shared/Site.Master)Leave it as is, I add a new View and for it's Master Page I browse to the new Nested Master Page.When I click Add, the following Error comes up:"The ContentPlaceHolder 'MainContent' doesn't exists in the Master page '~/Areas/xxx/Views/Shared/NestedMasterPage.master'. Please choose a valid ID for this Master Page.Bit buffled..the code for the nested master look like this:[Code]....
'MainContent' right there, or what is VS talking about?

View 4 RepliesMy web site will have lots of pages, too many to provide links for in the menu as shown in the form of the wizard-generated menu. One solution I'm investigating is to have a main menu where each item will pop up a submenu, like in a Windows app.
Can I use a "Menu" control in a master page to do a pop up menu? If so can you point me to an example or show me (a novice) how to do it? I.e., each item will have a controller action, so how do I connect the menu item to the action method?
Is there a way to assign pages created from a master page with their own meta tags? I know that some search engines don't weight meta tags very highly, but I still would like to use them if possible.
View 3 RepliesOur web app currently under development has authentication on all the pages.
We can deny a user access to any particular page but have found that if a user had previously opened the page that they can still access the page via the url. [Even if they log out and log in]
Assuming that the page is coming from client cache [Ctrl F5 in IE kicks in the proper authentication behavior or clearing the client cache]
A lot depends on how we have implemented the authentication but a quick fix on our side would be from within the admin section where we deny access to certain pages that we expire client cache for that page.
Is there a way to do this programmatically.
This would mean that client caching would continue to work as normal for all other users that still had access to the page in question.
