AJAX :: How To Call A Server Side Method From Client Side
Jul 16, 2010I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?

View 5 RepliesWCF - Call Same Service From Client And Server Side
Jun 15, 2010I have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding.
I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions.
But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config.
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
ResponseFormat = WebMessageFormat.Json,
RequestFormat= WebMessageFormat.Json) ]
How do I have a WCF service that can be called both from the server-side and client side (jQuery/ajax)?
Or put another way, this may be incorrectly worded, can an endpoint have multiple bindings?

View 4 RepliesCall To PageMethod Blocks Until Complete; Prevents Client Or Server-side Redirect
Jan 22, 2011I'm calling a static Page method via javascript that takes between 5s and 10 min. I'd like to give my user the choice to either continue waiting for the request to complete or not, and use window.setTimeout() to check back every 30s.
I've tried both location.href = '/newpage.aspx' or firing a button's click handler (which does similar redirect) to redirect the user prior to completion of the page method, to no avail. I can immediately send user to a simple html page, but a redirect to any aspx page involving server-side appears to block. When the page method finally completes, the redirect does succeed.
Is this:
a browser issue? If all modern browsers support at least 2 concurrent requests per domain, why wouldn't this work?
a framework limitation? a desirable design pattern or even possible? I've checked, and after redirecting to an HTML page, the original request continues processing (db updates, no problem).
Javascript - 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.

Web Forms :: RequiredFieldValidator Not Firing After Client Side Script Call
Mar 1, 2011I have a form that contains controls that have RequiredFieldValidator.

How To Ensure Validators Fire Before Call Client Side Javascript
Feb 4, 2011I have an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.

Jquery - Options For Page With Matching Client-side And Server-side Markup?
Oct 17, 2010Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

Server Side Control Hidden - Possible To Read Values Client Side
Jan 30, 2010I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
View 1 RepliesJavaScript - Exposing Server-side State Through Client-side Controls
Feb 11, 2011I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
