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

Nov 23 10 at 20:46

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" />

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">
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

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.

Accessing Client - Side Generated Table Rows Through Server - Side

Feb 23 10 at 5:07

The idea is that a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button). These rows contain textboxes, dropdownlists, checkboxes and other input controls. When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on server side, validate it and perform other actions on it.

I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows. put me in the right direction?? Or someone offering a better solution to the problem?

MVC :: RC2 Client-Side Validation Infinite Loop Bug?

Mar 03, 2010 09:04 AM

I've found a bug with RC2's client-side validation that causes an infinite loop (at least in IE7).Basically, if you create a standard ASP.NET MVC 2 RC2 web application template and then modify the LogOn.aspx view to this:


Note the new table that has been placed around it.Now, when you fire it up in IE7 and hit "Log On", the whole browser freezes and goes into an infinite loop.I have narrowed this down to the use of OnPropertyChange and the setting of the CSS classes for the elements themselves. It seems whenever an element is in a table, and you change its CSS class, the OnPropertyChange event fires with the property of "value" (which fires the entire process off again hence the endless loop).This is reproducable for me in IE7 (I haven't tested FireFox, IE6 or IE8).

JavaScript - Exposing Server-side State Through Client-side Controls

Feb 11 at 14:31

I 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...

Web Forms :: Client Side Javascript And Server Side Codes

Aug 24, 2009 04:23 PM

I modifed an existing asp.net page to handle existing radio buttons onclick event (were not there before) as the result of newly added database table. When the user click on one of those radio buttons, i process the onclick event using the combination of javascript function and ajaxpro to query the infomation from the newly added table. In order to display the result from the query i added a panel to the main form and formated it into a html fragment and display it inside the panle using document.GetElementByID("panelID").innerhtml. The panel displayed the information correctly, which consider of a line of text (label control) and the number of checkboxes (the number of checkboxes varied depend on the number rows returned). At this point the user can make changes to the selection as desired. I would like to save the text of those selected checkboxes when the user click on the Save button of the main form. The problem is when i view the source code under internet explorer the only reference i got is the newly added panel. There were no mentinoned of those checkboxes and the lable eventhough they are displayed. Using server side codes inside the code behind page, the panel has no child controls. I guest the only way to acces them is using client side javascript codes. Right now the implementation for the save button is done using server side codes (c#).

Can i inject a block of javascript code inside my code behind file when process the panel like below:
private void ProcessPanel()
// passing the id of the panel to the javascript block below
<script type='text/javascript'>
// i want to be able to read the checkboxes

If not, what other options do i have to be able to read those checkboxes?

JavaScript - Detecting Client-side DOM Changes Server-side - Is It Possible

Mar 7 10 at 2:45

I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).

This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?

Web Forms :: Accessing Client-side Table Rows On Server?

Jul 23, 2010 06:39 PM

I have a table that the user can add rows to through javascript by clicking on a "add rows button". In each row there are two columns one with a dropdown list and the other a text box. The dropdown list is populated with data through a sub on server side code.I need to be able to insert the data from each row into a table but I'm unable to do this. I clicked on my "add rows button" to add several rows and then did a test to see how many rows the table was returning on the server side and it did not include the five rows I added .. only the header row.If there is a better way to allow users to dynamically add rows to a table and then access the dynamically created table on the server then I'm all ears!

Javascript - How Much Client-side Programming Is Needed When Doing Server-side Programming

Mar 16 at 23:12

but I am rather confused about what to invest in. I heard that server-side code translates into client-side code. So, if you have an .aspx file, it will be converted to HTML/CSS/JavaScript. I have experience with the latter three technologies put into a rather dull text file and rendered by a web browser. My question is how much HTML/CSS/Javascript coding would I have to do when server-side programming? In other words, can someone using ASP.NET program purely on the server side and not bother to write for the client side? Of course, I don't care about server-side being translated into client-side, but I am wondering if client-side programming needs to be done explicitly and to what degree.

Javascript - User Control With A Client Side API

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");

Javascript - Disabling A Label From Client Side?

Feb 2 at 15:54

I have a webform that has a lot of controls and a submit button. When a user submits clean data, there is an asp.net label control that displays a "form submitted successfully" message. My problem is that after this successful submission, if the same user enters some invalid value for some fields on the same form and clicks on the submit button, the page still displays the success message along with the asp.net error message for that field (By using the asp.net validation control). My question is how do I get rid of the success message in this scenario? (In this case all I want to display is the client side validation error message). I am not that familiar with javascript.

<asp:Button ID="btnAddActivity" Text="Add Activity" runat="server" onclick="btnAddActivity_Click" ValidationGroup="vgSetup" OnClientClick=" return changeLabel();"/>
<asp:Label ID="lblMessage" visible="false" ForeColor="red" runat="server"></asp:Label>
function changeLabel()
document.getElementById('<%= lblMessage.ClientID %>').innerHTML = "";

Here is the markup for the label and button .I tried calling a javascript function on the OnClick event .This disables the success message, but the validation error messages are displayed after a post back.I want to display the validation error messages without a post back.

Javascript - Disable Client Side Validation For Some Fields In MVC?

Mar 21 at 9:04

How can I conditionally disable client-side validation of some fields ?

Here is the example of what I need to do:

user writes name and address and submits. Both are validated both server and client side. If validation passes e-mail is send to given address and (name, address) pair is stored.as a response same page is displayed (I don't want redirect!) this time with confirmation. User can retype their name and submit. In such case e-mail will be resend to the address that corresponds to given name.

It does not work because: client side validation will not pass when user clicks resent button on the second (confirmation screen). It would say that e-mail is required even if there is no field for it. How can I disable javascript validating email before the confirm page gets send to user ?

Example ASP.NET MVC page

<%if (Model.Confirm == false){ %>
<% using (Html.BeginForm()) { %>
Your email: <%: Html.EditorFor(m => m.Email) %>
Your name: <%: Html.EditorFor(m => m.Name) %>
<input type="submit" value="Send Email" />

Is there any other way (besides putting all of this into a global .js file) that this example can be improved? If including this into the main .js file is the "best practice" alternative, then why?

Client-side JavaScript ViewState Update In .net Forms?

Feb 3 at 15:47

I have stumbled upon the issue when I need to retract html controls I've added client-side using JavaScript after the postback (due to server-side validation - this is not optional). I'm trying to achieve this is cr*p and there's a better way of doing this.

basically, what I'm doing is cloning a textbox control for up to 10 times on the page when the user hits "Add" and storing entered values from each of those texboxes in a hidden field to read from in the code behind. This works fine, however, when the server side validation doesn't pass after postback, all those dynamically added (cloned) texboxes disappear, since ViewState knows nothing about them.

I am considering 2 possible solution, both of which seem hacky:Rebuild all cloned textboxes on document onload() using stored values in the hidden field wrap the form in ajax update panel and place the cloned texboxes outside of it, thus, not refreshing this part of the screen on postback now, is it possible to somehow "update" ViewState to make it aware of all the html controls I've added using client-side script? I'd like to achieve this with client-side script, therefore not considering cloning textboxes on server-side,
