RadioButton Client Event Not Triggering?
Apr 22, 2010
I'm dynamically generating radio buttons in my code behind and assigning javascript to them as they are created. This javascript will change the value in a hidden field for when a postback is eventually triggered (autopostback on the buttons is disabled). I am using the exact same method with ASP ImageButtons and it works fine but when I do it with the radio buttons the event never triggers the Javascript. I suspect that I may be using the wrong event name but I have tried several (onclick, onCheckedChanged, etc).
Here is a sample of the VB.NETcode - how come this works fine with my button but not my radiobutton!
//This is my hidden field
ClientScript.RegisterHiddenField(Me.UniqueID & "_someVariable", "")
Dim radDefault As RadioButton = New RadioButton()
radDefault.GroupName = "radio buttons"
radDefault.AutoPostBack = False
//This adds the Javascript to set the hidden field with an onClick event
radDefault.Attributes.Add("onClick", "document.forms[0]." & Me.UniqueID & "_someVariable.value='0';document.forms[0].submit();")
The code is simplified as the button generation is actually through an iterator but the same properties are given to each generated radio button.

I've created two buttons using javascript; yes and no. I need to get the event triggered when the button is clicked.i.e... onclick=getvalue().
public void SetYesButton(string msg_button_class) {
this.msgbox_Yes_button = "<input type="button" value="Yes" class="" + msg_button_class + "" onClick="getvalue()";>";
}
public void SetNoButton(string msg_button_class) {
this.msgbox_No_button = "<input type="button" value="No" class="" + msg_button_class + "" onClick="document.getElementById('pagedimmer').style.visibility = 'hidden'; document.getElementById('msgbox').style.visibility = 'hidden';">";
}

My application allows a team captain to enter the results of an 8-ball game then submit those results. In doing so the captain is brought to the next page to enter the results of the 9-ball game. But, there are games every week so there is a dropdownlist on both of the forms allowing the captain to select which date he/she is entering the information for. There are 14 weeks with the date displaying as the text value.
After the user selects the appropriate date and enters the results of the 8-ball game he is brought to the next form but he has to select the date again. Both forms ddl selectedindexchanged event enacts a whole lot of code which is required to allow the processing of the data.
I can capture the selected value from the first form and get it to the next form for 9-ball and even set the selectedvalue correctly, but that doesn't trigger the selectedindexchanged event. I want to put some code in the pageload to pass the selectedvalue to the selectedindexchanged event and trigger it to run with that value.
Is this even possible? I haven't been able to google my way out of this perdicament despite many hours of effort. And I know that users are going to spend 20 minutes entering all the data before realizing that they forgot to select the correct date in the ddl. What to do?

In my ASP.NET app I have a control in the master page that raises an event Foo on certain occasions / interactions.I also have a couple of pages that have another control that must re-bind itself when this event is fired.Unfortunately the only way I can see them communicating between each other is by creating a long event chain (deriving a new MasterPage MasterPageSuperDuper, attaching an event handler to Foo's event in the user control, and then referring to this event in the masterpage from the control present in a couple of pages - basically using the masterpage as a control center).

look at the code below.btnCustomDateOk dosen't trigger postback at all.it's supposed to run a date range validator (javascript) first and if succeed then triggers a server-side event.(I've been testing around and when I replaced the button with a linkbutton, everything ran perfectly fine, wt? am I misusing the button control?)

I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.

I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.

We have an UpdatePanel that is showing a gridview with loads of data in it. We have loads of well written sprocs that don't take very long, BUT we have a few horrible ones that take ages.
We do intend to rewrite them but in the interim we have put the ADO.NET commandtimeout up to 180s. The scriptManager.AsyncPostBackTimeout is set to 240s. We want to handle this on the serverside. One of the reports still fails (it's got a couple of nested cursors in it - someone who hasn't had SQL lesson 101 from me!).
Half the time, the nice error timeout message is shown using server side handling of the command timeout. The problem is that the other half of the time the commandtimeout doesn't seem to fire.

I built a webcontrol showing a complex user interface with a lot of javascript. Basically my webcontrol is similar to : [URL]
Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.

ASP.net radiobutton change event writes the new selection to an XML file and that needs to be shown on the page but does not show the changes on the page since the page load occur before the event fires. give some insight how to resolve this.

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) {

i can use javascript setInterval() (in combination with jquery ajax) to 'poll' the controller action in order to determine if something 'new' should be renedered onto the page. However, I'm not a huge fan of polling, especially when client browsers can be left unattended and are uneccessarily polling for changes.
Multiply that by the number of potential client machines that could be browsing the app and you get a feel for the scale of the issue with this approach. Now, in truth, this is EXACTLY the approach that I use to refresh certain page fragments on some ('read' - MANY!!) of my existing sites.
However, I'd like to know what the options are for subscribing in 'reverse' to events and having the controller 'know' about the client browser and any events that it is subscribed to and the controller then 'push' out the update to the client on a 'needs must' basis. Is this something that happens outside of the normal desktop events scenario?

I am having trouble with the Asp.net page life cycle. I am trying to create a custom menu using HtmlTextWriter with an asp.net LinkButton to fire a server event. I can not get the server event to fire and I get the 'object reference not set to instance of object' when I click my linkbutton. Here is some code.
protected string CreateModuleMenu()
{
var modules = ModuleManager.GetModulesByDeveloperId(Developer.DeveloperID);
StringWriter sw = new StringWriter();
ClientScriptManager cs = Page.ClientScript;

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.
