Event Handlers Not Firing When Client Side Change Occurred In List Box

Apr 27, 2010

I have two list boxes and I am using javascript to interchange the items. My problem is, When I press submit button before any changes in the listboxes, it would fire the eventhandler. But when I made any change in these listboxes, a postback happened and the controls became invisible. (There is an html tag and an empty body tag in the source). I know listbox cannot preserve the client side changes to the server. But I could not identify the problem.

Web Forms :: ASP.NET Validation Controls Are Removing Client Event Handlers.

Nov 24, 2010

The textbox has an onblur event (the workings of the onblur event are irrelevant), and an associated RequiredFieldValidator. This code functions exactly as it should. However,if in the body onload event I simply raise an alert of the innerHTML of tr1 or td1, the onblur event does not appear (but it does work, and can be seen when I view source in IE7). If I remove the RequiredFieldValidator, the onblur event handler is shown in the alert, or if I retain the validator but change onblur to onfocus, then the event handler also appears in the alert. I need this to work as when the user increases the Quantity, duplicates of the table row are added (I have tried both cloneNode, and setting the innerHTML of each new table cell to that of the original, but as my alert proves, the onblur event handler is not included in what is copied). The same problem also occurs with onchange for select tags with validators. I am using Visual Studio 2008 (.Net
2), IE7 and IIS 7.

How To Wire Up Javascript Event Handlers To Events Happening On The Server-side

Jun 30, 2010

I was wondering if anyone had an easy way to wire up javascript event handlers to events happening on the server-side. I have a long running process that includes a lot of steps, and would like the client to be continually updated with new information as the steps transition. Will this involve some sort of polling mechanism?

Web Forms :: How To Fire Server Side Event After Client Side Event Is Triggered

Sep 12, 2012

I have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.

Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?

 OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.

displayAlternate('second'); return false; --> if i do this server side event is not fired ...

If I return true div second label is not getting displayed..

How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..

Below is code.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head><body>
<form id="form1" runat="server">
<script type="text/javascript">
function displayAlternate(id) {

Web Forms :: RequiredFieldValidator Not Firing After Client Side Script Call

Enable/disable RequiredValidator On Client-side / CustomValidator Not Firing?

Apr 23, 2010

I've got a drop-down where the user selects a Country. It is a required "field".Next to it, there is a textfield named State. If the user selects US, then the field State is required. If the user selects e.g. Sweden, the State is not required, since Sweden has no states.Example code:

<asp:DropDownList runat="server" ID="Country"></asp:DropDownList>
<asp:RequiredFieldValidator ControlToValidate="Country"
runat="server" Display="Static" ErrorMessage="Required field" />

Button Click Event Still Firing Even Through Custom Server-side Validation Fails?

May 27, 2010

I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards.

MVC :: Client Side Validation For List?

Aug 14, 2010

I have a problem of Validation still present for list object that have been dynamically deleted in the View. Here is the scenario. In my model I have a list. This list can be added and deleted dynamically in create and edit views. Lets say I am in the create view. I add two list objects dynamically and start filing the object and submit the form. The model validation fails in the server side (client side validation cannot be done as it involes some complex logic) because of some errors. Now the errors are being disaplayed for the two objects. Now I delete the first list object dynamically and correct the errors in the second list object and try to submit but the form will not submit because, the client side validation still thinks that the first list object is still present. Is there anyway to remove the client validation for objects that have been removed dynamically ?

My model

Contact.cs:

public class contact{
public List<Address> address;
}

Steps for the problem.

1. Create two addresses in the create view.

2. Fill the fields and click submit.

3. Server side Model validation will report errors for fields.

4. Delete the first Address and correct the errors in the second object and click submit.

5. Submit will not work because the client side validation expects the errors to be corrected in the first Address which has been deleted.

AJAX :: Change Event Not Firing After Callout Message In A Popup?

Mar 1, 2011

I have a popup which displays two drop down lists, name it : ddl1 and ddl2 and for both of these i have mandatory validation, so if any of these is not provided, callout message will come on submit click.

ddl2 will get populated once any value from ddl1 is selected(selected change event).

Now problem is, suppose without entering any value, i click submit, it is showing select value for ddl1, and when i select a value, the selected change event for ddl1 is not firing, and so ddl2 is not getting loaded.

Selected change event for ddl1 is firing in normal condition, if the callout message is not there.

but after the callout message, if i try to select a value, the event is not firing.

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.
