I have a ASP.NET web-site built on 2.0 framework. This works fine on IE and firefox. Now I do few ammendments to the web-site and build it on 3.5 Framework. My question is what upgradation I need to force on users of my site. Do users need to uprade with the version of IE. How does the client machine get .NET 3.5 specific assemblies.
Is it necessary for user to install Fx 3.5 runtime?
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 am working in a web form (VB.NET ) in which for certain transaction i need the user OK to continue or not.
all what i found is about adding onClick event handler for buttons, but in my case there is no button to click , it's a process in which i retrieved data from database and if that data met specific conditions then a message of OK Cancel should appear to the user prompting him if he would like to continue in that transaction .
I have tried every single method in almost every post available on both Bing and Google. And I still get this error.I thought it was something in my website or web.config, so I opened up VS2008, selected to create a new ASP.NET Website and let it go..Here is the default.aspx page and web.config created by VS2008. Without modifying anything other than chaning the website properties to .NET 3.5 instead of .Net 2.0, I still get the error on this website when I hit F5. I have other websites with the ajax update panel and script manager on this server that work fine and have tried the web.config from them on a new project. But any new projects still do not work.I have verified that the settings for the working project as well as this new project in IIS are the same. Can anyone tell me why I am getting this error and theSys Undefined error?

Maybe I've picked a totally inappropriate/bad example. What I have is a user control that contains a bunch of dynamically created Telerik RadGrids. My user control is added to a couple of Telerik RadPageViews that are part of a RadMultiPage that is used alongside a RadTabStrip. What I need to do is call a Javascript function in my usercontrol to update it's display whenever it's parent RadPageView is selected.
So basically I have the following Javascript code:
function OnClientTabSelected(sender, args)
{
// Get the MyControl that is on this tab
var myControl = $find("whatever");
// Call a method that updates the display
myControl.doSomething();
}
I am trying to add some client side functionality to a user control that I have written.
A really simplified version of my scenario is as follows:
I have a control called MyControl. This has a javascript method called doSomething that simply shows the current date and time in an alert box.I add an instance of MyControl to a page called WebForm1. I want to be able to call myControl1.doSomething when a regular (non ASP.NET) button on WebForm1 is pressed.
I'm sure this is really simple but I can't for the life of me figure out what I need to do make doSomething available.
When am using below code it's working fine on my local host but when am host on server getting error.
Response.Write("sam "+System.Net.Dns.GetHostEntry(Request.ServerVariables["REMOTE_HOST"]).HostName);
Error:
The requested name is valid, but no data of the requested type was found.
I have created a user control that has a gridview. During binding I set some common properties like height and width. To do so, I have created public properties. I have created the public property so that user can also set the height and width themselves. But if user didn't specify then I use my defaults.
My problem is that user settings are always overridden by my default settings. I want to set the default values as the control is rendered on the page and then if user apply his settings then it shold override. Which event/method is best on user control to jandle such scenario? Where should I write the code to call my default settings so that it is first thing that happens? What is the user control life cycle?
I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.
Is there a client side event that occurs on a user control when its parent submits to the server?
View 1 RepliesI was using RangeValidator to validate user input on client side for double values.One of my user said that when he enters 5E-10, my range validator does not understand that number as a valid double.

View 2 RepliesI have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I
insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):

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?

View 4 RepliesI am trying to set a hidden type value to x on Server Side and then access it with Javascript. I have tried multiple ways to accomplish this.
At the basic level this is what I am trying to do.
Aspx page

CS Page
In IsPostBack
HidRowNumber.Value = EFileRowNumber.Text;
Javscript
var status = document.getElementById("<%= HidRowNumber.ClientID %>").value;
When I am debugin it say it HidRowNumber's Value has changed to x but when I access the value with JS it always returns ''.

I'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 RepliesI 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...
