Web Forms :: 3.5 Events - Is Supposed To Fire On The Client Side When Text Is Changed

May 27, 2010

I'm new to ASP.net 3.5 and testing functionality before developing an asp.net web site. I created a page with a formview. I added several text boxes. I created an event on the FirstName_TextChanged event and added a stop in the sub. When I open the page in the browser and type in some text in the FirstName and press tab, nothing seems to fire.

1) Is this supposed to fire on the client side when text is changed?
2) If so, would the vb.net code entered work like Javascript code on the server?
3) If so again, is it possible to update another textbox based on the text entered into the FirstName on the Client Side (would do this in Javascript in Classic ASP)?

I think I'm totally confused. I've been searching web for article about how to do this.

MVC Pattern Clarification - Doesn't Support Server Side Events But Supports Client Side Events

Apr 6, 2010

Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)

1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.

2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.

3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.

Web Forms :: How To Fire Server Side Event After Client Side Event Is Triggered

Sep 12, 2012

I have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.

Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?

 OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.

displayAlternate('second'); return false; --> if i do this server side event is not fired ...

If I return true div second label is not getting displayed..

How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..

Below is code.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head><body>
<form id="form1" runat="server">
<script type="text/javascript">
function displayAlternate(id) {

Client Side Script For Treeview Events?

Dec 27, 2010

I have a Treeview with "populateOnDemand" set to true. I want this treeview to keep its state (nodes expanded/collapsed) from one page to another. Viewstate doesn't work because the treeview is different for each page. Here is my code at the moment.

ASPX page :

[code]....

This works well, buf I wish I could avoid the postback everytime the user expands or collapses a node. I know I can set EnebleClientScript to true and manage the events client side in Javascript but I won't be able to use my session variable anymore. Is there a way to achieve this ?

JavaScript - Can Wire Up Client Side That Would Fire Regardless Of The Update Panel

Jul 23, 2010

I have an asp.net page that is using and update panel and am including some javascript via a {script src=abc.js} tag. I have tried loading my javascript using both $(document).ready and $(window).load. Both fire on the initial load but fail to fire on an update panel postback.

Is there anything I can wire up client side that would fire regardless of the update panel? I know I can inject script server side but I ideally want to do this all client side and wire up what ever is needed the first time around.

How To Ensure Validators Fire Before Call Client Side Javascript

Feb 4, 2011

I have an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.

How To Preserve Literal Text From Server Side When Displaying On Client Side

Mar 2, 2011

ASP.NET newbie question - fastest fingers!

I have a page that needs to pull some script off the server, including tag info, for the page. Thus:

<html><body>
blahblahblah
<%: Model.TaggedField %>
</body></html>

Problem is, the value of Model.TaggedField may include HTML tags, but the page automatically converts the tag info to <myTag> etc.

What method can I call to make the value of Model.TaggedField be transmitted verbatim to the page?
