Web Forms :: How To Add Some Client Side Functionality To A User Control

Feb 28, 2011

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.

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

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.

Use AJAX Control Toolkit Client-side Functionality Without IIS?

Feb 8, 2011

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?

Client Side Click Event Of Control In User Control Doesn't Work?

Jun 14, 2010

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. :)

Javascript - User Control With A Client Side API

Feb 28, 2011

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();
}

Server Side Control Hidden - Possible To Read Values Client Side

Jan 30, 2010

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?

How To Get Same Validators Control To Both Client Side And Server Side

May 20, 2010

For 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?

Custom Server Controls :: How To Set The Default Settings Before User Set Them Client Side

Jan 10, 2011

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?

How To Force The User To Have At Least One Selected Checkbox And Postback From Client-side JavaScript

Jul 8, 2010

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.
