What is the best way to ensure that events are rebound after an UpdatePanel callback?
function pageLoad(sender, args){
//bind events here.
}
or
use the .live(eventType, handler) method to initially bind the events
or
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function() {
//bind events here.
});
I have a updatepanel which contains of a few dynamically created ImageButtons (the ImageButtons are placed in a panel inside the updatepanel) Since the imagebuttons are children of the updatepanel they automatically triggers a callback to server, fine. But I want the user to be able to cancel the callback after clicking on the imgbutton, preferably through a javascript window.confirm.
I have managed to make it work with a jquery function returning false (i dont know why it works, dont really understand asp.net ajax functionality) but it only works until a callback is done, then I guess I have to rebind the jquery to the controls in the updatepanel or?this turned out to be a jquery question. How do I rebind the recently loaded controls in my updatepanel to my jqyery function? the controls all have the same class and I use that to trigger the jquery function.
aspx file
..
..
$('.myImgButtons').click(function(){
if(window.confirm('Cancel callback?') )
return false;
});
..
..
<asp:UpdatePanel ..... >
<ContentTemplate>
<asp:panel id="myPanel" ........ ></asp:Panel>
</ContentTemplate>
<Triggers>
..whatever..
</Triggers>
</asp:UpdatePanel>
aspx.cs file
..

ImageButton dyn_ImgButton = new ImageButton();
dyn_ImgButton.Attributes.Add("class", "myImgButtons");
add dyn_ImgButton to myPanel

I have updatePanel in my ASP.NET 2.0 (migrated from ASP.NET 1.1) web app. It doesn't work as it always postback instead of callback. I already set<xhtmlConformance mode="Transitional" /> but still not working. Previously, it just working.

I wanna assign a JavaScript CallBack function to an UpdatePanel which will be gets called when the UpdatePanel finishes its tasks. After, the UpdatePanel will be sending a string as a result. This JavaScript CallBack function will have to process this resulting string.
View 1 RepliesI have a usercontrol with listview control nested inside an UpdatePanel and Panel. Below is the layout:UserControl :: Panel1 -> UpdatePanel -> Panel2 -> ListViewUpdateMode is set to conditional. Panel2's visibility is initially set to false.In the containing page, I load the usercontrol and bind the ListView, turn on the panel2 and call the update method of the updatepanel (since action is initiated by an external button and not a child of updatepanel) which displays the rows successfully. However, none of the edit, select or delete actions execute the intended way. When I click any of those buttons, I can see the
UpdateProgress fine but the events seem to be not firing at all. Execution hits the PageLoad but not into any of those event handlers likeItemEditing, SelectedIndexChanging etc.
What I did is, I have made 2 user controls. One control is inside the other.
NoW one control has a buttton and a data grid and datalist in it. When pressing button I am filling datagrid while datalist visiblity false. This is working fine. But now when I press some link button in datalist data, it should call item_command event but it is not calling.
I have also used a Updatepanel as a wrapper(all controls are inside it).
i have had this problem before but haven't found a solution yet. The solutions that i have come across are either bad for security or worked on old versions of the .Net framework. I am using VB.net with framework 3.5 and i get the following error when clicking on a button that is a trigger for an updatepanel:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
The msg states that you need to use the ClientScriptManager.RegisterForEventValidation but i can't find anywhere which shows a working example of this in VB.net & in .net framework 3.5. Can anyone give me a step by step guide on how to resolve this postback validation error?
I have a button that is within an updatepanel control. The button's click event has a function defined for it through JQuery. Once the async postback completes the JQuery event fails to fire when the button is clicked subsequently. What do I need to do to correct this behavior and maintain the JQuery event attachment to the button's click event once it has been refreshed asynchronously?
View 1 RepliesI have the following within an updatepanel. If i make a selection somewhere else that has its own updatepanel, this data gets cleared.

What am i doing wrong? each updatepanel has its own trigger assigned to it.. so why would updatepanel#1 trigger cause updatepanel #7 to post and cause the field to clear? Even if i tab out of the textbox before completing it, causes the field to clear..
When I have a control within an UpdatePanel which is within a ModalPopupExtender panel, after the FIRST successful display of the modal (by clicking OK), the events of the control are not functioning. I have the full source code below of a working example of this. How do I get around this?In the sample, when the modal is first opened checking and unchecking the checkbox updates the textbox. Clicking OK updates the textbox in the outer UpdatePanel. Opening up the modal a second time will now prevent the checkbox from updating the textbox.

I have got an issue after updation in UpdatePanel. The issue is the jquery events are not working/firing after the updation in UpdatePanel. At first time, the jquery events work, but not after the updation in UpdatePanel. If I remove the UpdatePanel, the problem is solved. But I have to use the UpdatePanel.
View 1 RepliesI have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.
View 4 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.

I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?
how can we ensure that a sub,it is not be used by two or more clients??
View 21 RepliesI've been working in asp.net webforms and I've been making a UserControl that depends on a small bit of javascript which is in an external file.
I want to be able to put a reference to the javascript inside the UserControl to ensure that it gets loaded on the page, but the problem is that the UserControl can appear multiple times on a page so I only want the script to be loaded with the first instance of the UserControl.
Is there an easy way to do this in ASP.NET Webforms?
Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.
I am doing a survey. so basically, i will send out an email with a unique link and the person clicks the link which directs them to my aspx page. that controls i use will be bound to a datatable.
first I will need to show their existing home and email address in a control.
then i will give them 4 checkbox's to tick a certain option. also, how can I ensure only one checkbox is ticked all the time?
I will need the checkboxes to be bound as well, to show the options they chose incase they load the page again after saving.
I have some classes which can't make assumptions about de used culture. These classes should always use CultureInfo.InvariantCulture. However, I can't set the thread's current culture to CultureInfo.InvariantCulture, because other classes rely on <globalization culture="auto".
Is there a way to ensure some classes always use explicit culture method calls (like: Convert.ToDecimal(value, CultureInfo.InvariantCulture)) instead of assumed culture (like: Convert.ToDecimal(value)).Maybe my question it's not 100% clear: I'd like to detect all methods which have an overload which uses CultureInfo, but also one without the CultureInfo which uses the CurrentCulture.This includes implicit casts of numbers to string:
decimal value = 1.0;
string displayThis = string.Format("Costs: {0}", value);
The goal is to make sure some classes/methods don't assume anything about CultureInfo.
I can remember reading something on this in a book but I can't remember. How do you ensure that certain graphics have been loaded to the users computer before any of the page is rendered?

So the problem is the following :
i do have own user control. which has some javascript file in script tag included like this
<script type="text/javascript" src="../somefile.js" ></script>
or some javascript code directly on the ascx page. everything works if i place this control somewhere in aspx markup. but if i add this control to the page dynamically to some UpdatePanel place holder on postback (this is logic i can not alter), control renders itself and then i get js error message, which says that functions which are placed in somefile.js are not defined/are null. Why is this happening ? Is there anyway to force js including in this case.
the code amount is huge and i was not able to provide a simplified example with the same error,.
The script is included but somehow the functions are not defined. I'm novice to js, so is it possible that just the script is included but not executed, so the functions are not declared ???
The interesting is that if on some page my custom control is declared in aspx.
