Web Forms :: Client Validation Prevents AutoPostbacks On First Click Of AutoPostback Control?
May 4, 2010I have an issue that I've been fighting with for some time. I have a large web form, with update panels and autopostback controls. When the users click "submit", some custom javascript runs which shows validation summaries and turns the fields with errors red, relatively easy, and it works as expected. The problem is that I have a dropdownlist which should autopostback an update panel. It does this perfectly if the user does not click the submit button, and therefore my custom client script dosesn't execute.However, if a user clicks submit, the custom client script executes (turns fields red and shows validation summaries), and then the dropdownlist does NOT autopostback the first time a user changes it's value. If the user changes the dropdownlist's value a second time, then the autopost back occurs and everything functions as it should. I don't understand why the autopostback is disabled for the first click after the javascript executes. Can someone please help me out? The DropDown List looks like:

The Submit button is:

View 1 RepliesC# - Show Only Client-side Validation With Client And Server Validators?
Dec 12, 2010If 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?
C# - Client-Server App, Want To Create A Client Simulator ?
Oct 11, 2010We'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?

View 1 RepliesJavascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked
Nov 23, 2010I 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.

View 3 RepliesResponse.Cookie Client Or Server/where Does The Cookie Saved? On Client Machine Or Server Machine?
Mar 7, 2011When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?
EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
[code].....
I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.
Scenario:On Page_Init() on code behind. I create a cookie using Response.Cookie.Add(new HttpCookie("MyCookie", "cookieValue"));.
On Client side, I'm trying to read the cookie saved from code behind on page load using the snippet above, but it returns undefined

View 1 RepliesDoes Access To Server Resources Require Client Process To Login To Server Machine
Sep 22, 2010Reposting my unanswered in technet.microsoft question?
MSDN "ASP.NET Delegation" article tells:
1) "When you configure to use a particular account as the process identity, ASP.NET attempts to delegate that account. If it is a local account that is identical (including password) to a local account on a remote machine, delegation is possible. If such an account does not exist on the remote machine, to the network it appears as the Windows anonymous account (NT AUTHORITYANONYMOUS LOGON). In addition, delegation is also possible if the account is a domain account that has access to the remote machine, in which case it uses the domain network identity of that account."
The same frequently repeated story as in case of manually/interactively accessing remote computer (server resource) in workgroup - it is necessary to create local account with the same username, the same password. But why?
If a workgroup Windows client process cannot access resources on server machine without having duplicate of such (local) account on target machine already pre-created,does it mean that client (process, machine, or user) can access server resources only by/after having logged (opening logon session) into server machine? Or, how to understand that such access is impossible without having corresponding duplicate local account on server machine?
The same MSDN "ASP.NET Delegation" article tells:
"NetworkService account. It behaves the same as the System account. This account possesses the network credentials associated with the machine account (domainnamemachinename) in the domain of which it is a member"
Does not any Windows have accounts ((NT AUTHORITYNETWORK SERVICE)? as well as many other common pre-built accounts? Why are they installed (before any joining to domain) but cannot be used for remote network access and client identification ? And what is identity used when the process from workgroup Windows under identity ((NT AUTHORITYNETWORK SERVICE) accesses a remote server?

AJAX :: Server And Client Side Timeouts - Server Timeout Not Triggering?
Nov 22, 2010We have an UpdatePanel that is showing a gridview with loads of data in it. We have loads of well written sprocs that don't take very long, BUT we have a few horrible ones that take ages.
We do intend to rewrite them but in the interim we have put the ADO.NET commandtimeout up to 180s. The scriptManager.AsyncPostBackTimeout is set to 240s. We want to handle this on the serverside. One of the reports still fails (it's got a couple of nested cursors in it - someone who hasn't had SQL lesson 101 from me!).
Half the time, the nice error timeout message is shown using server side handling of the command timeout. The problem is that the other half of the time the commandtimeout doesn't seem to fire.
Web Forms :: EnableClientScript - Only Clientside If True Or Both Client And Server?
Nov 18, 2010subject says it all...... when using the various validation controls like requiredFieldValidator, and EnableClientScript is true (the default), does that mean that the only validation is done client side? or does it mean that it is done client side in addition to server side?
I know if the only validation is done client side, like with javascript, it can easily be circumvented. I want to make sure my validation is done serverside, so do I need to set EnableClientScript to false?
