C# - Click Event Not Firing When Page Is Inactive For Some Time?
Jan 13, 2011
I have couple of [WebMethods] in my code behind and using jquery ajax to get data from server. And then it happens :). After some time while page is inactive when i try to click on button which should have send request to server it simply does nothing for about half of minute and only then event is fired and i get response from server.
im creating a button control in page int and im assing a click event for the button control. here the click event is not firing for the first time. here is my code.
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.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I am using frames in my webpage.in one of the frames i have a menu control whose items are database driven.when click on the menu item, i want another page to be displayed in other frame.
now i want to pass the the selected menu item text to the other page using session variable which is in the menu item click event method.but the thing is when i click on the menu item, the click event is not firing.
is there any better way to pass the selected menu item text to the other page?
I have an ASP.NET 3.5 web application. There is a Master page with lots of client script and some simple server side controls. I have a user control that has a modal popup extender inside an update panel and some client script as well. When I add this user control on the Master page inside a new update panel whose update mode is set to conditional, and I add a link button whose click will initiate a method of this user control, the Master page's behaviour changes in a strange manner. All the buttons and link buttons start to fire their Click even on the second click. Nothing happens on the first click. As soon as I remove this user control from the Master page, everything seems to get back to normal and Click event fires on first click as it should. I hope I have clearly mentioned the problem here. I have already spent quite a long time trying to find out the reason for this but of no use.
I am generating UserName based on FirstName.LastName after that I am hitting the database and checking if this username (Like AAA.BBB) exists or not if not then I am generating email address, if yes then it is thorowing error which is correct. And after this when I changed the username (Like AAA.BBBC) and hit enter or tab then again it should check the database and generate the email but it is not doing any thing means I think I am missing the cursor control or Second time TextBox_TextChanged event is not firing.
In that site, I have a drop down list which allows the user to select from a number of forms with AutoPostBack set to true. I have a OnSelectedIndexChanged event on the dropdown which loads the correct control depending on which option is selected. See below:
[Code]....
Now, that works correctly and loads the form as expected, but the server side onclick event within each ascx control now doesn't work. Is there some problem with button events when controls are added this way? When I add the control in manually to the page it works fine.
i am using VWD(visual web developer 2008) and DOTNET 3.5
i have a page on which i dynamically add multiple datalist controls on the oninit event of my page , on postabck i again add all these datalist controls to the page on oninit event
the template for all the datalist controls is defined using the ITemplate interface, the template defined for each datalist control contains a button which has a event handler attached to onclick event.
the problem is first time i click the button on postback i add the multiple datalist controls , the event gets fired which modifies the datatable i am using to generate my datalist controls and the datalist controls with the modified data show on the page but the second time a user clicks the button inside datalist the event does not get fired.
I have a webfrom on which I have some textbox controls, validation controls and button controls. When I click the button is validating the form but when I fill the text boxes with valid data and click the button nothing is happening i.e. the page is not posting back and button_onclick event is not firing. Below is the markup.
I've placed a link button control on my web form and added the click event to the code behind automatically), but I've placed a break point and it never hits it. If I do the same thing with a button it works just fine.I've searched for this problem and none of the results seem to answer why mine isn't working. Maybe I'm just missing something?
I have Onclientclick event attached to the button in serverside code like below,TopPanelButton.OnClientClick = string.Format("if(!ValidData({0},{1},{2},{3})) return false;", txtOD.ClientID, radCmbOD.ClientID, txtgetMe.ClientID, RadAjaxLoadingPanel1.ClientID);Also, the onClick event is attached for the same button in the aspx page,
The serverside click event should fire if the onclientclick return true. The "ValidateData()" function is called to validate the entries in the form.This code is working fine in IE. But in Firefox, both events are not firig. If I comment the "TopPanelButton.OnClientClick =..." code then onClick event is firing.
i want to upload mp3 songs and also download it....
i got code from our partner site and it is useful but when i click on upload button then it doesnt go to that click event so that code is not working...
my code is:=
protected void mpsong_button_click(object sender, EventArgs e) { using (BinaryReader br = new BinaryReader(FileUpload1.PostedFile.InputStream)) { byte[] bytes = br.ReadBytes((int)FileUpload1.PostedFile.InputStream.Length); { {
This is my approach : I reserve last time that a user post a postback to server in a session and in every postback subtract this value from current value. Is there a better way for this?
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?
I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code.
LinkButton lnkNext = new LinkButton(); lnkNext.Text = "Next"; lnkNext.Click += new EventHandler(NextPage); if (currentPage != objPagedDataSource.PageCount)
[Code]....
So I am incrementing the cookie I am using to track the page number and then rebinding the repeater.
Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly.
Gridrow Button click loads aspx Page1 which is a Modal window(window.showmodaldialog). It has an ascx in it called UC1. In my Page1 following is added.
<head><base target ='_self'/></head>(this was added to solve the problem of losing session data on load of Page1) I cannot do away without this code.
I am assuming this is avoiding Pageload event of Page1 when the same gridrow button, who opens up Page1, is clicked the second time. Please note that after second click I can see the page1 with all it's controls but when I try to debug, I see that it does not raise the page load event the second time. It's as thought the page had been cached or the same frame is gettign loaded.
Problem is I want to raise the Page load event the second time also beacuse my dataload for Page1 happens only on page load. PS: Please note only the second click onwards page load doesn't happen. the first time pagelaod works. If I click a new row's button the first time it works.. later it stops doing a pageload
I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.
I have a GridView control bound to an AccessDataSource. After selecting a row I'm creating a table inside the selected row. I'm adding Buttons to this table. Their Click event never gets fired. I read about recreating the buttons and stuff, but still no luck solving the issue.
I have two asp.net buttons in my page.If i make button cause validation false then am able to fire button click event on server side but not able to validate text box values(but i need to validate text boxes) using required field validator.
I have a UserControl, which has few textboxes, RequiredFieldValidator and a submit button. Every thing was working fine and now suddenly the button click event stopped working.If i set the CauseValidation= false for button, then it s working fine, but i can not do that because i want user to enter some value in the textbox.I investigated that it might be RequiredFieldValidatoe which is stopping the button to postback, but why its doing like that if you have entered the values in textboxes.
Am adding a sample webpart dynamically in which i add a Button Control.the isssue is Event is getting fired when i Click on the scond time and the other issue is the web parts are getting duplicated for each postback.
