Implementing Client Callbacks Programmatically Without Postbacks In Web Pages
May 6, 2010
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.

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?

i have a really annoying problem in that i need to programmatically create a SQLDatasource and then add it to my asp.net page on the load event. If I do this it all seems to work ok in terms of data binding but for all buttons on the page their postback events stop working?Is this a know issue or must I be doing something wrong?

I need to implement an AutoComplete feature for a voting system with drop down names. Here is the code for the multiple text boxes. All need to have the same drop down names, which I would like to hard code, and not put in a DB.
[Code]....
I don't really know how to do an AutoComplete function. I've searched on the internet, but none are simple, and none are quite what I'm looking for.

I have a section on my website where I plan to add a lot of text-based content, and rather than display this all at once it would be nice if I could add paging on just these pages. If possible, I would like to put all of my content within one content item and have the paging work automatically, building a URL along the lines of http://example.org/articles/title?page=2 or similar.
I've stumbled across an article that mentions paging with Sitecore items and this seems rather close to what I require, although mine requires pagination on a single content item, rather than multiple items.
Is it possible to do this with a Sitecore content item?

I have a quite advanced application, where I need to add some client/server functionality. Some examples of functionalities is:
Chat
One vs. one fight in a browser game
Draw people on a map
I am creating this application in ASP.NET and AJAX. I do not use Silverlight/Java Applet/Flash or anything else. If possible, I do not want to change this for other reasons.
I thought about creating some kind of game server, and then communicating either web services or TCP protocol: But I have NO idea if this is a good idea. Also, I don't know how to do this.
So my question is:
What's the best way to implement this? And is it even possible? And if it is, could you give a reference or two?

I am using URL Routing in my .Net Web Application. I would like to prevent users from being able to access the .aspx page.
Example:
Actual URL - [URL]
Routed URL - [URL]
I want users to be able to access the page only by going to /Testimonials, but I would like to setup /Testimonials.aspx to redirect to its route at /Testimonials.
Is there an easy way to do this for Routed Pages throughout the application?

I want to have an upload functionality for uploading large files -- as large as 1GB. I see some sites successfully implementing reliable upload functionality without using any upload clients e.g. ActiveX, Java, etc. Some suggest, the secret is sending the large file in smaller and more manageable chunks to the server. If that't the case how do I handle that?

I'm dynamically binding tables and sub tables using nested listviews. On the client side I have a piece of jQuery that is toggling the visiblity of TRs witin the tables in order to provide a group expand / contract view option.
On postback I'm obviously loosing my class changes that I have applied via jQuery. I'm wondering what the best approach to maintaining these client side class changes is? I've considered creating a hidden input control per table to store the indexes of the visible TRs at the time of expanding them. The intention being to then look for the indexes during postback / rebinding and add the visible classes to each corresponding element.
Is there a better approach or some native method of passing back the client side style / class change to the server during postbacks?

I've created a wallboard application to display outstanding support calls for my ICT department. I've bound a number of gridviews to sqldatasources which execute a stored procedure. This is automated via asp.net ajax controls and partially refreshes the page/data every 30 seconds.
At the moment, when the number of records in the gridview goes over 9, the gridview automatically pages and shows the number of pages in the bottom right hand corner. The helpdesk can then VNC to the box which controls the screen and manually click to see what's on the next page.
What I am after is a way to programmatically (using the c# code-behind file) changing the current displayed page after 10/15 seconds or so, obviously if this is possible in the scope of the gridview. I trailed using javascript (and failed at jquery) of scrolling the gridview within a div, however this didn't work as expected.
Can anyone point me in the right example. I can't find anyone else querying this functionality via a quick Google.
Gridview Code:
<asp:GridView ID="GridView1" ShowHeader="False" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
GridLines="None" CellPadding="2" Font-Size="35pt" AllowPaging="True" PageSize="9">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID">
<ItemStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="ASSIGNEES" HeaderText="ASSIGNEES" SortExpression="ASSIGNEES">
<ItemStyle Width="32%" Wrap="false"/>
</asp:BoundField>
<asp:BoundField DataField="title" HeaderText="title" SortExpression="title">
<ItemStyle Width="53%" Wrap="false"/>
</asp:BoundField>
</Columns>
</asp:GridView>
SqlDataSource Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FPConnectionString %>" SelectCommand="HDMonitoringOutstandingToday" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

I am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:
[Code]....
[Code]....
The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...
[Code]....
...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?

I mean, it's easy to add a Button programmactically to an aspx page, but a server control's event handler probably has to be set early in the page life cycle (maybe before Control.Load event). As a result in reality, are dynamic controls rarely added to apsx pages?I wish there is a way to call postback at the server, so that a event is never too late.

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.

Our 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.

I am designing an ASP.NET web application (.NET 4.0) which basically has a page that should interact with the code behind every 1-2 seconds (Using Client callbacks or PageMethods via ScriptManager or jQuery.ajax) It'll be hosted on an intranet, so a 1-2 second refresh rate is kind of reasonable.
How can I make the page to access the web service/pagemthod in the code behind in a timeply manner (e.g. every 1 second). Should I use a javascript timer (I'm not familiar with javascrip very much)?
Although the site is hosted on an intranet, but I still need to implement a good approach to reach the desired refresh rate. the amount of data being transfered is about 1KB in each interaction. What are your recommendations on my design regarding this? (using callbacks or ScriptManager or jQuery.ajax,...
