Web Forms :: Button Click Triggers HTML Table Refreshed Even Put Within Postback Block?

Aug 6, 2010

I'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.

Here is the code part:

Button Click Event Handler Before Page Load?

Jan 12, 2011

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

Button b=(Button)sender; Session["CurrentId"]=Convert.ToInt32(b.ID);

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?

Web Forms :: Button Click Event Is Called Before Page Load?

Oct 8, 2010

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

This is how I tried to implement this:

Web Forms :: How To Show A Processing Message While Page Is Loading In Response To A Button Click Event

Apr 28, 2010

I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive processing occurs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs.

How do i show a message in this case, that the processing is still going on and ask the user to wait.

I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page ?

Force JQuery Click Event To Proceed Any Control Click Event On Page?

Mar 22, 2010

I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.

C# - Button Event Handlers Do Not Fire On The First Click But On The Second Click After A PostBack

May 4, 2010

Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.

Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.

I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.

Example of Button Definition (within GetAdministrationInterface)

Web Forms :: Text Change Event Eats Up Button Click Event?

Feb 18, 2011

I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.
