I'm trying to prevent the user of double clicking on a submit button.I have been looking arround for the solution but still can't get it to work.
[Code]....
Now when the user clicks on the button it is diabled and the page,load event is fired. But it does not fire the buttons click event.
<asp:LinkButton ID="LinkButtonNewServicesCategory" runat="server"
OnClientClick="this.disabled=true;return false;"
style="float:left;margin-right:5px;" CausesValidation="False">new services category</asp:LinkButton>
The intent is that when the LinkButton is clicked, it disables itself and returns false to prevent the postback (this control is used as a trigger for an animation).
I dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.
View 5 RepliesI have page on which I've a login control in which I've a subnit button. The problem is this that when I refresh the that page the submit button or any button that was clicked last before page refresh gets its click event automatically fired.
View 1 RepliesI have an aspx page that is wrapped with an UpdatePanel control, users can post comments and delete them later, when the user clicks the delete for the first time it deletes successfully but if he wants to delete another comment, it works only after two clicks on the button.the delete button is inside a web user control that is added dynamically at run time.
View 1 RepliesSituation:
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?
Every time we click on a button. the Page_Load will fire first.
For my case, I have some controls added programmatically to the GridView, when the button click, the Page_Load event fire, my controls just go away.
I have a textbox control i disabled view state at page and control level.i entered a value in the text box and click a button there is a postback,no business logic in the button click event.The values in the testbox are persisting though i disabled at the control level and page level.
View 5 Replieswhy the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
View 3 RepliesI am creating a button dynamically in my code and attaching a click event to it. However I have to prevent people to click it while there is a process going on. So when it is clicked once, it should be disabled and when the process ends it should be enabled. How can I do that?
View 4 RepliesI want to restrict the user if they select the language which is already selected by displaying alert msg using JQuery.
Is there any event which fires before the change event.
I can't figure out why, but before my form is even displayed, the CheckChanged event fires. I don't even have a chance to check anything. Has anyone seen anything like this?
View 3 RepliesPage_load event fires two time in firefox and the same page is working fine in IE. What might be the problem? If it is problem with Autoeventwireup then page_load event must fire two times in IE too. I believe it is not a issue of Autoeventwireup.
how can i find out exactly where the issue is.
I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?
I have:<asp:TextBox ID="Profile_EMail" runat="server" CssClass="form" />
and
<asp:RegularExpressionValidator ID="Validator_Profile_EMail"
runat="server" ControlToValidate="Profile_EMail"
meta:resourcekey="Validator_Profile_EMail"
ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*">
on my ASP.NET form.
When user uses browser embedded autocomplete list and selects any element by pressing "Enter" button, validator fires. Always validation is not passed. Email pattern is proper. When user press "save" button, validation passes correctly.
I have the following problem. I have a user control with its own events and procedures. I added this control to a page programmatically. It appears as it should but when you click a button on the user control. the control disappears from the page.
View 6 RepliesI have a LinkButton which fires an OnClick event to update some Labels; however, after the first firing of OnClick, it won't fire again when I click another (or the same) LinkButton which runs the same OnClick event. (It's a list of people, each a LinkButton, and clicking on one brings up their details)
If I leave the page a few minutes, it will work again, almost as if whatever was preventing OnClick firing timed-out. Of course, this won't be any use to the users!
This is my ASP.NET code for the LinkButtons (encapsulated in a DataList):
[Code]....
All the connections work, the data is retrieved, etc, so everything except the OnClick firing works. I've done a search of the internet and the forum, and found this seems to have been a long-standing problem since the first ASP.NET, but there is no solution for ASP.NET 3.5. Does anyone know what causes this, or where I might be going wrong?
OK, been burning up Google and Bing trying to figure out a good solution to this problem, and so far, I feel like I've taken a dive down a rabbit hole - I'm just waiting on the Queen of Hearts and the Mad Hatter to show up. Alice is kinda cute, but unfortunately, she didn't have any good suggestions, either.
Here's the scenario - I have a User Control on a Child Page that has a Master Page assigned. The control is for logging in to the system, so it contains two text boxes, a couple of links to password recovery and registration, and an ImageButton to handle submission of the username/password entered in the text boxes.
Everything works just as expected when the user actually takes the mouse and clicks on the ImageButton control.
Things don't work so well when the user enters a username and password and then presses the Enter/Return key.
While debugging, VS2005 (I know...ugh!) will stop at the LoginButtonClick event, and seems to run the code. Of course, the .Text property of the two input controls was empty, but the Request.Form collection had the values burried within the collection of Keys.
So, a little bit of digging got me to the point where they can login using either the Enter key or clicking on the ImageButton. So, everything seems like it's good, right? Nope, not so fast.
When I enter a username/password combo that's designed to fail authentication, the code will step through setting the error message, etc, but that information never makes it to the point where it's visible to the user.
I'm not seeing any extra postbacks (obvious ones, anyway), but for some reason, when the page goes to redraw when it's in a "failed" state, the notations just simply aren't there.
Below is the code in the User Control that handles the actual authentication routine. All controls, such as the Label with ID "message", are local to the User Control, so I don't think it's a FindControl("message") problem or something similar...just so bizarre that it disappears seeming without reason.

I am using radiobuttonlist and textbox in the gridview. I need to do operations on radiobuttonlist so that it should reflect on textbox . this is to be done after gridview_rowediting event fires i.e when we can see "update" and "cancel" buttons. I tried like this,
[code]...
here default selected value is "0" given in source.
My problem here is when I am changing the selecteditem, the corresponding action is not done.
I have a table with a button in it. The table is wholly built in the code behind. When I click the button, I want to rebuild the table with a new parameter. This all works great. I have a buildTable function that returns the table. It is called during the repeater itemdatabound and called again at the onclick event. The problem is, when the table is built from the onclick event the buttons do not work. In fact, the onclick event is never called.
View 13 RepliesWe are developing our application on a 64 bit server. We are using a dropdownlist to filter and display departments in a htmltable(hide and show rows) on every selectedindexchanged event.
The issue is it is firing properly for the first time, but it is not doing a post back there after. We have even given autopostback=true. We are using AJAX for hiding and showing the rows of the htmltable.

all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.
I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :
[Code]....
[Code]....
On the Page_load event of my page i bind the data & recreate the control :
[Code]....
Everything works fine, datas are bound and SelectedIndexes are restore on every postback.
The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...
I have a fairly complex master/content page that has several GridViews - each one in its own UpdatePanel. I also have four CustomValidators on the page, each one assigned to a different
ValidationGroup. Two of the CustomValidators are buried inside a HeaderTemplates of a GridView (inside a distinct UpdatePanel). In the EmptyDataTemplate, HeaderTemplate and FooterTemplate of each GridView I have ImageButtons that postback to the server to perform some operation. All the ImageButtons take this form:
[Code]....
When I click on the ImageButtons in one of my GridView's the ImageButtons cause the ServerValidate event of two CustomValidators to fire. The server-side OnClick event of the ImageButton never fires. I have verified that the ImageButton(s) have CausesValidation="False" - what could be causing the validators to fire?
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
