I 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 4 RepliesI want to do something a little bit tricky here. I want to call a server side fonction from the javascript. I know it can be done but I get some errors. This is my Javascript fonction where I want to call the server side fonction:

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.
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" >
hi ihave this functin in .vb file
Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click

How to call JavaScript function from server side
View 2 RepliesI 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?
I have a function in Code Behind, Can any one let me know "How would I call this function using javascript"?

What I want to do: dispose of a session upon detecting an "OnBeforeUnload" event in the client. I know it doesn't fire 100% of times (90% accuracy works fine for me)

I am building a user registration form in asp.net. I want to check if the username is available or not on the leave event of the TextBox. I am not able to get the Leave Event of the TextBox.

but got a readonly error.
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
Suppose 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).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?
