Web Forms :: Showing No Webforms To Client?
Sep 2, 2010
I have (probably for you) a strange question. How can a server receive a url from a script and not return a webpage. The server should only process some data of the params in the url.So, the clientmachine, which runs the script, doesnot notice anything at all from the server. On the serverside it is like using only a module and not webpages for processing some logic.Can someone give me hand how to program that on the server (W 2003)?

I have a website in ASP.NET (WebForms, NOT MVC) which has a survey form divided in several slides. Each slide has a next button that, obviously does a transition (client-side, not post back or remote request) to the next slide.In each slide I have several ASP.NET controls with their related validators. I want this validators to be triggered when I click the next button (or maybe when each input loses focus?).
I remembered ASP.NET doing client side validation on lost focus, but maybe I'm wrong... (I quit doing ASP.NET development about 3 years now, so I can't remember)UPDATE: It would be better to make ASP.NET trigger each validator when the associated control lost focus. I remember ASP.NET doing this (or am I dreaming? =P)

i need to implement a tab functionality in a web page, which displays different gridviews on click of each tab. There might also be navigation buttons inside each tab for displaying popup and refreshing back the tab content on closing the popup.
Kindly let me know what approach would be an efficient way of implement this.
In my mind there are two options,
a) simply use imagebuttons(as i need to have custom image for tab header which i am not able to do it in ajax tabcontainer) and multiview controls to display various tab contents in a single *.aspx page(But i think this would mess up the aspx page with lot of code, as i need to have approx six gridview and its functions).
b) use an iframe instead of mutliview and make each tab content as seperate *.aspx page. (but i find there is postback occuring on movement from one tab to another even if i button iframe inside updatepanel & some people are request not to use iframes).

I guess you guys probably have seen this before.
It is caused by my WinLogin.aspx and WebLogin.aspx (since I have local and out-side users)

I have started having problems with our asp.net webform applications running behind a proxy since the user base have upgraded to IE7. Some postbacks seem to drop out and at times it is difficult to make controls on a page raise an event. It appears to be intermittant and I have been told there are issues around using IE7 behind a proxy with post requests. Is this the case and what are the options? Rewite in MVC? Does the issue of post requests behind a proxy remain in IE8?

I'm going through my apps and carving out as many querystring URLs as possible by using Routing instead.For our product catalog,we have many product categories that have characters like ampersands and slashes in them which don't go over to well when used in a URL.
I'm currently using Page.GetRouteUrl in my databound objects to create URLs like "~/catalog/My Category", which gets encoded to "~/catalog/My%20Category", so I used string.replace to smooth that into "~/catalog/My_Category".
But then, as mentioned, I have categories with commas, ampersands, slashes, quotes, &c.,
My question: is there a general way to easily deal with these characters in route keys, or do I need to develop a list of URL-friendly characters to use and replace all of the ugly ones, then un-replace them when I'm passing the route data to my LINQ statements?If that's so, then I can't use <asp:RouteParameter /> in declarative markup.

I founding problems publishing the webfiles using a normal FTP user wich I can use correctly using any other FTP clientI also getting a error when publising my database. I am connecting via the databaseserver IP or host using a normal SQL authentication that works fine at any other connectionscript.What is going wrong?1) Does anybody have a clue what is going wrong?2) Does anybody have a manual or something to publish a ASP.NET Webform from your local machine to a live Windows server?

Basically I am using gridview to pull data (Question/Question ID) from our SQL server. I am trying to write a program that allows me to check certain rows and a button that sends the checked rows to a seperate form with placeholders.
Is it possible to program a button to send checked rows in gridview to a seperate form with placeholders and if so how would I go about starting?

I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.

If I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?

We've got a client app which connects using TCP to a server. Additionally, the client app makes use of .NET remoting to talk to another piece of locally running code.
I'm tasked with creating a "Client Simulator" to do some testing, where we'd need to have 100's of clients connected simultaneously to the server. Ideally, this would work out great if I were to run each client in it's own space, such as a VM, but this is not logistically feasible.
how to handle this? Is there a tool that could do something like this? Or some sort-of .NET concept I could use?

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

I'm going to create my own project, and i have some difficulties with technology selection. I will have client application(windows forms) and web service. Data exchange between clients will be only by using this web service. Data will be like image stream,so I don't know which technology to use. I started to look at WCF, but i don't know a lot about it.
