I want to enhance a composite control's client side, my approach is to recreate all method on JavaScript, so here I have some troubles :
1) Can I call onclick event on client side otherwise on server side ?
2) the statement table.onclick=SelectRow(event) fires a bug !

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 want to develop composite control where some of the work would be executed on client side. For that I am implementing IScriptControl.
ScriptReference points to a script file with client object.
Let's say I want it to have Listview(html select) control that onselect will run javascript function based on the selected value.
I can't just create the control dynamically is client js, because the control has UI on design mode so I must create the select control on server side (I create it in override void Render)
My problem how and where to assign the onselect event for the selection.
Update: Maybe I should add select's id as property to ScriptControlDescriptor, then in client control retrieve this id and attach the needed handler to the event?

I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.
View 5 RepliesI'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 4 RepliesFor the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?
I am using the formview control where while calling an control from the formview by means of script it gives an error mesg. By typing the script inside the control it works outside showing error. How can i call it. So I use an FindControl methods its shows an error

I 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):
[code]...
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
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 = $find("whatever");
// Call a method that updates the display
myControl.doSomething();
}
Let's say I have a DropDownList server control, called "CategoriesDDL" and the ClientID proeprty determines its client side id, which is its ID prefixed with the id's NamingContainer's ids. In this case the client side ID is CP1_CategoriesDDL. But what is the rule regarding the client side name, in this case "ct100$CP1_CategoriesDDL"?

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.
I am using ASP MVC 2 RC2 and playing with client side validation. my problem is that i have a form which has a checkbox and text box.
the textbox should be validated only if the checkbox is checked. I was nto able to find anyway to disable the client side validation when the checkbox is not checked.
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?

View 2 RepliesI am dynamically changing a slider control's maximum value based on an onchange event on a different control.

Ho Do i change a value of a label control using client side?
function Test()
{
document.getElementById('Labelj').innerHTML
= 'Your new value';
}
The problem i am having is: I am trying to input the code, but when i type in the javascript, it is not recognising the "innerHTML" value. It is not being promted in my intellisense, therefore the function is not working..is their something i am missing?
I have a textbox in my application which has multiple validation on it e.g. RequiredFieldValidator, RegexValidation and CustomValidation. My page has several similar textboxes. So I just copy-paste and change id and controltovalidate properties and it is working.
Since similar tbxs are going to be used on another page as well, I think it would be nice to create my own custom TextBox control with built-in validation.
Here are two approaches I have found and tried:
1: Implement from IValidator perform my custom validation in Validate Method. As shown here: Self-Validating TextBox But it does not show how to implement client-side validation.
2: Create custom control that derives from TextBox and add asp.net built-in validators I need. As shown here:Custom TextBox. I tried the code and it works server/client side.
I like the first approach but don't know how to implement client-side validation. I know I need a client-side js function. I can do that. I know how to include my js file using Page.ClientScript class but don't know how to integrate all together and make it work.
I can create a UserControl or the second approach above but for now I am specifically looking to learn and implement client-side validation from custom control.
