AJAX :: Textbox Postback Causing Radio Button List To Lose Selection?

May 27, 2010

This is likely a n00b question, but I can't seem to find any info on how to solve it. Here's the scenario:

I have a Textbox and a RadioButtonList in an UpdatePanel, both with AutoPostBack turned on (they need to be, can't turn it off on the text box))

The user enters some text in to the textbox, then clicks one of the Items in the radio button list.

Because the textbox post back is executing, the radio button is losing the value that the user selected.

How can I workaround this?

Forms Data Controls :: Populate A Datagrid On Selection From A Drop Down List?

Mar 17, 2011

This is my first post as a newbie to asp.net.

I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.

What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.

So far my edit page has a datagrid with the following code:

I dynamically add the webcontrol in onInit or onload (page_load). it will cause the second post back and with the ispostback==false;

if first enter the page is no problem. but if I click on the some button. it will trigger postback two times.

first time: ispostback = true.

second time: ispostback = false.

the second time postback caused me headache because all my value has been initialized due to the coding like below:

Web Forms :: Find The HTML Of Entire Page Causing The PostBack ?

Jul 30, 2010

I need to know if there is any server-side function/custom-code available to find out the HTML of the entire page which is causing the PostBack.

I don't want to do it using JavaScript/jQuery but instead do it at server side.

A JavaScript workaround that implements it can be found at this link. [URL]

Reason, Why I need it? I am writing some inline javascript in page which performs some vital actions and supposed not to be tampered by user(hacker). So, when a postback occurs, I would like to find out the HTML of entire page (at server) so that I can verify it (I have already generated the hash code for entire HTML while rendering the page to check it on consecutive postbacks) for non-tamering and then process further.

This is the reason why I need a way to find out the HTML of the page causing the PostBack.

Web Forms :: CheckBox Oncheckedchanged Event Causing Strange Behavior On Postback?

Jun 11, 2010

I have an issue that seems to only happen on my production server. I show or hide table rows whenever the buttons are clicked. However, when I do a postback on the checkbox, all of the rows become visible and the textbox stays empty. It works correctly on my test server and local workstation, just not in production.

Here is the markup...

Here is the code behind...

Here are the unexpected results whenever I check the chkShow2 checkbox... I am guessing this is a configuration issue on the server.

Web Forms :: Create Via C# In An Event Causing Page Validation To Occur On Postback?

Feb 14, 2011

I'm having trouble with an image button I create via c# in an event causing page validation to occur on postback. The CausesValidation attribute is set to false at time of creation in the event. I also wire up the Click event in the page_init with postback so not to loose the event handler if the page posts another way. Here is the code I'm using in the click event of a Button. I've also tried to enable and disable viewstate for the button with no luck. What am I missing here that continues to fire page validation in the Click of this imagebutton?

AJAX :: Update Panel Causing Complete Postback?

Jan 1, 2010

Below is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

TemplateField Button Causing GridView Invalid Postback?

Jun 3, 2010

I've got a template field in a gridview that contains just a simple button...

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Administration.aspx.cs"
Inherits="Administration" %>
<%@ Register TagPrefix="ajaxToolkit" Namespace="AjaxControlToolkit" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

[Code]....

Whenever I click the button I get the error...

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.

I've found a decent amount of articles referencing this issue, including a couple on SO, for example...

and...

I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?

Which Control Is Causing Invalid Postback Or Callback Argument With EnableEventValid

Mar 8, 2010

I have searched high and low on this error, but my problem stems back to which control is causing this problem. In theory the problem starts when someone goes to a specific tab and clicks a button to download a PDF file. After doing that if I use a dropdownlist the error pops up.I have checked the code etc. just cannot figure out which control is triggering the error. I can identify the control that is the problem?

This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.
