Web Forms :: The Serverside Event For The Button Is Not Triggered And PostBack Is False
Nov 18, 2010
I have a problem with the ASP FileUpload control. It occurs in Safari and on websites where anonymous authentication is disabled and windows authentication is enabled.
When I select a file in the upload-control and then press an ASP-button the serverside event for the button is not triggered and PostBack is false.
Steps to reproduce the error:
1. Create a page with a file upload and a button. Print a message in the page's load event so you can see that if postback is true or false
2. Open IIS-manager and Add a new application that points to the folder where the page is
3. Disable Anonymous Authentication, ASP.NET Impersonation and Forms Authentication for the application
7. Enable Windows Authentication for the application
8. Browse to the page with Safari
9. Select a file with the upload control
10. Press Ok. Postback is false
If you then enable anonymous authentication on the web application and restart the browser postback works as expected.
I know about Always vs. Conditional, I just need to know exactly which update panel's data needs to be refreshed (not taken from app tier cache) on the serverside.
Server Click event is not being triggered when I click on the "LookupButton". The weird part is that this code works on our Dev server, but not QA. If I get rid of "LookupValidationGroup", from the Lookup Button ValidationGroup property, the page does postback, but then my validators do not work. I could explicitly do the validation on the Server Side, but dont think I should need to.
No errors are being displayed. I also reinstalled .net 3.5 using aspnet_regiis -i command.
Can i know the code written in C# to get a current time when a button event is triggered in ASP.NET web application project and time retreived is to saved in SQL database
I had an MVC 1.0 web application that was in VS 2008; I just upgraded the project to VS 2010 which automatically upgraded MVC to 2.0. I have a bunch of viewpages have codebehind files that were manually added. The project worked fine before the upgrade, but now the onclick even't don't get triggered. I.e. I have an asp:button with an onclick event that points to a method in the codebehind. When you click the button, the onclick event doesn't get triggered. In fact, when you look at the Page variable, IsPostBack is false.
This is really bizarre and I'm wondering if anyone know what happened and how to fix it. I'm thinking it has something to do with the changes in MVC 2.0; but I'm not sure. (deleting the codebehinds and moving that to the controller is not really an option since there is so many pages, moving back to vs 2008 is a last resort as I want to make use of some of the VS 2010 features like performance testing.)
I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"
In my form I have a label and button control.By default the label is visible. When a user clicks on the button I have made the label to visible false.For simple button it is working, but when I add an updatePanel to button the event is getting fired but the label is not getting to visible false. this is happening and the solution for this.
When I click on the aspx Submit Button, the file selected in Silverlight control should be uploaded and after the completion of upload, the Server side event should get called.
i have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?
I have a textbox which is read only and there is a calendar besides the textbox. When the user selects the date in the calendar pop up, the text in the textbox is populated but it doesn't trigger the text change event. trigger an event when the text is changed on the textbox?
I have TreeView on a Sharepoint aspx page. The tree is populated dynamically using a Sharepoint list containing a folder-stucture. I would like to handle Select-actions but I am not able to.. the SelectedNodeChanged event only seems to occur when I select the outer-most nodes. Minimal example code for the UserControl where the TreeView is located is found below.
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.
I have created a user control which has a form and 2 buttons; Save and Submit. Both buttons are created at design time. Users can enter details in the form (e.g. title and description of an item) and click Save which does some server-side processing to create an 'Item' then clears the form.
The buttons:
[Code]....
[Code]....
And a placeholder to add dynamically created controls:
[Code]....
I am saving the Items in ViewState and dynamically creating a LinkButton control for each Item which allows the user to edit the item:
[Code]....
[Code]....
Now, when I test this in Visual Studio 2010, it works fine;
1. Enter Item title and description in form
2. Click Save
3. Save button triggers postback and onClick event code is run
4. ViewState list is displayed below the form
When I create a local IIS web site for testing, the postback on the Save button only works the first time I click it. Postback is false on the second click and the page reloads without running the onClick event code.
My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
I have a checkbox in gridview. I have a onclick event in which i am checking if there are more than one record selected in the gridview, i need to select only one and de-select other checkboxes.
This is my aspx code:
[Code]....
This is my checkedchanged code:
[Code]....
I am not sure why the check change is not getting trigerred. And, is this code correct for selecting only one checkbox
I 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.

I'm having asp.net ajax tab container in a datalist control with 4 tab panels. I set ActiveTabIndex to 0 on .aspx page, and using OnActiveTabChanged event in code behind, when the tab container tab index is changed, server side event is not working, when i debug the code, i can see the event is getting fired, even though i click the third tab, i'm getting Active TabIndex "0" only.
<cc1:tabcontainer id="TabContainer1" runat="server" AutoPostBack="true" Font-Names="Calibri" ActiveTabIndex="0" Width="710px" CssClass="yui" align="left" OnActiveTabChanged="TabContainer1_ActiveTabChanged"> Server Side Code:
