I have a Asp:modal (AJAX) that works fine on a master.page
When i then add an asp:menu with sitemapdatasource, then the page works fine first time at page load, but if i then click the btn that trigger the asp:modal i get this error
[URL] ....
What I want is that the user can write an email in a textbox on the masterpage and then hit a btn, if the email is valid 100% the event is trigged and the asp:modal is showed, its works fine when i dont have a asp:menu on the masterpage, but when i then add the menu, then the pages works, but when i will trigger the asp:modal then i get the error.
i have an form with an button and some input controls. some time due to input problem i may get error after that if i refreshed the page then that time the button click event has fired, how to avoid this kind of bad event fire.
i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
I will describe my problem in simple way so it's not exactly what I'm trying to do but the idea is the same.Here is the problem:
I create dynamic buttons from code behind.I get some id from query string,create button with that id ,dynamic add event handler to click event,and add button to placeholder.I store the list of id-s in session and in page load method recreate these buttons and add to placeholder.One of the id-s is CurrentId and it's also stored in session.Buttons click handler do something like this
In page load when I create buttons I want to set button text property different from others if id==Convert.ToInt32(Session["CurrentId"]) when list of id-s are gotten from session.But problem is that click event handler is called after page load,and when I create buttons in page load ,CurrentId in session hasn't been channged by click event handler.Can you suggest any solution to this situation?
I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
I am also facing some issues with Back Button of Internet Browser as well. Actully Page Load event of my page is not firing when i click on Back Button of Internet.
Trying to get a helloworld web application up running in Visual Web Developer 2010.
Now I created a new project with Home controller and two default views (index and about).
Then in the index view I added a button and a textbox...double clicking the button creates a handler in the view, but it's never called...what am I missing?
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
How do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Base Class:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then RaiseEvent FirstLoad(sender, e) End If End Sub
Derived Class:
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad 'Stuff here happens before controls load but only on first page loads' End Sub
I have a update panel on the ASPX page,When thepage loads the content in the update panel shouldnot load ( Update panel should show the Updatepanel progress control) but after page load update panel contents should load . How do i get this efect.
I am using a third party gateway. The third party gateway does not support query-string , so i will need to post the form to pass the values to the given URL and another thing is that they don't expose the web-services so we need to use their page and that means we need to host it in an iframe in asp.net
so what i did is that i have hidden fields that will be used as parameters as depicted below
Now the purpose of this , is to load the iframe after the page load event of the asp.net gets fired.
Now my problem here is that when the iframe loads , it does not pass the parameters to the url that is being set in the iframe.
I have attached the example, project. (2kb)
When you run the project you will notice when the iframe loads there is an Error
"NO VCS ID"
now this means that the parameters were not passed when the Iframe loads , i can understand because it seems like iframe does not do a full form post. so to demonstrate what i want, click the proceed button and you will notice it will give you a page with no errors and it will be a page where credit card details are required , i want to iframe to load that the first time.
In my application I am using ajax updatepannel in which there is a tab container tool having 4 tabs, in the third third tab I used ajax accordian control which has 2 panel each pannel have one gridview control a Remove button.

the depratment dropdown box get its value from sqldatasource.
[code]....
what i want is when i run the page, it shows the very first deparment in the list, and according to that it should pop up the values in the other fields, means it should show the values in the equipment dropdownbox and from that one it should pop up the values in the other textbox.
here is my selected indexchanged event for department dropdownbox
I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?
How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page Custom Control UpdatePanel LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin If is a partial post back AND a full postback is needed Page.DoFullPostback End If End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
I am new to asp.net and I'm trying to build my first web page, but when I try to fill a dataset at the page load event I get an error: object reference not set to instance of object. I've done this many times in vb.net. I can't figure out how to step through my code like I do when I'm creating a desktop app, so I don't know exactly where it's failing. I like to be able to see the values of things as it goes through the code.
Code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Label2.Visible = False Dim dsCheckExisting As New System.Data.DataSet() dsCheckExisting.Clear() Dim adLookup As New OleDb.OleDbDataAdapter adLookup.SelectCommand = New OleDb.OleDbCommand
I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.
i am loading a usercontrols dymaically, i need to create a event listener so any controls that i load will pass back a int id to my aspx page. what is the best way to create a dynamic listener?
Control FeaturedProductUserControl = LoadControl("FeaturedProduct.ascx"); Controls.Add(FeaturedProductUserControl); PlaceHolderLeftMenu.Controls.Add(FeaturedProductUserControl);
I have a simple form and i'm using a jquery to load a data (partial postback)...$("#divbody").load("OtherData.aspx?ID=12"); The OtherData.aspx contains a Data that shows in gridview and using a querystring..BUT the problem is when I click a button (default.aspx) I got an error...The state information is invalid for this page and might be corrupted.
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
I'm working on a wizard-like set of page, and I'm relying on cross page postbacks to navigate between them.
I need to be able to trigger the Load event on the previous page in order to save the form data for the page.
I've been told that for situations of this sort all I had to do is access the PreviousPage property in the destination page and this would trigger the load event of the previous page but for some reason this doesn't seem to be working.
Is there anything else I can do to explicitly trigger the load event on the previouspage if the PreviousPage property is not null?
now a days i'm working on my project. In project there is a aspx page which is binded with a masterpage, the problem is that when i run the project in debugging mode i found that page load event of a page is firing two times instead of one along with masterpage page's page load event. This is crreating a problem in filling a grid. I searched through the internet for this problem some says that it may happen if u have any image whose src="" or due to some bad HTML's on page .But i've gone through the page it does not contain any image whose src="" .
