View 2 RepliesI 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.
I ran an ASP.NET page that i have under development on my local IIS. It uses some dragPanelExtenders as well as some other AJAX Control Toolkit AJAX client side stuff, and in order to show the page to somebody, I wanted to put it up as a plain HTML file, hosted on a live web server (running APACHE). (This is the only public web server I have access to, and I want them to be able to drag some panels and experience the page as it would be when "live")
So, I viewed the page running on my local IIS, then saved the source as a HTML file.
Then copied this HTML file to the web server ( as well as necessary CSS, JS and image files).
When I view this HTML file through the web server, I get this error :
ASP.NET Ajax client-side framework failed to load.
By debugging, I see that the following lines were in my saved HTML :
<script src="/Insata10/WebResource.axd?d=VAXZudqFsChpNfB" type="text/javascript">
<script src="/Insata10/ScriptResource.axd?d=Dwbyv-OIp-kJQdqf_UMh7wUzi2" type="text/javascript">
<script type="text/javascript">
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
So, at runtime, the referenced resources "ScriptResource.axd" and "WebResource.axd" were not found.
Is there any way to get whatever is needed from those AXD's to my HTML file, without actually executing anything on IIS?
All my current functionalities are in .net datagrid. I have to include a new feature like drag and drop any row inside the datagrid to change the order of the row.
But, it should happen in client, during save the new order should save in the database.
Any plugins or scripts available to acheive this?
I am coding with VB.Net 2005. I have an issue popping up a message box on the client's side. The message box works well when running the application on my local machine, but when the site is hosted on the server, there is an error showing a conventional message box()in vb.net 2005 on the client's machine.
View 5 Repliesi 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 .
The error message that gets added to the validation summary when the form is invalid I need to get access to in client-side JavaScript. How do you access the actual message? My page doesn't have a ValidationSummary present, and Page_Validators[0].errormessage is *. Where is the message?

View 1 RepliesI 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" />

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.

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.
is it posible to add client side functionality to a custom server control in vb.net?i am looking at msdn library and there is no code for vb :/ http://msdn.microsoft.com/en-us/library/aa719700%28v=VS.71%29.aspxI fount this on MSDN Library Adding Client Capabilities to a Web Server ControlWhat i'm trying to do is to add some client functionality to my control, so that you can get or set some properties/values on client side. From the above link i see that this is doable with Ajax Server Control, but i don't have it, i have Custom Server Control. Can i do this with Custom Server Control and how?
View 16 RepliesIf I have a standard HTML textbox
[Code]....
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?

CS Page
In IsPostBack
HidRowNumber.Value = EFileRowNumber.Text;

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...
