i just made an onmouseover and onmouseout event using javascript and called the functions from the asp image tag like <contol.....onmouseover="thissss()" /> my question is why do i need to write javescrit for this? have heard so much praise of asp.net and c#! is there a way that is code to handle these events for all types of object using the .cs file (c#) directly?? i would assume the code will be under the page load event.
note:-
do not give answers assuming that the asker is a new bee consider him a completely un-educated person when it comes to coding )
I just need to write the string in one textbox from another one.But the problem that i felt is that what kind of event handing i need to include for textbox.Simply,when user type the particular string on textbox and when h/she pressed the tab button,then this string should automatically be displayed in another textbox within same webpage.

View 3 RepliesI'm developing IP Blacklisting HttpModule in asp .net application and I found one very annoying thing. Each request to the asp net page generates tens of "subrequests" to application resources like images, client side scripts, styles etc.
Now in my application I'm listing to the BeginRequest event and when it is fired I'm loading Dictionary with blacklisted IPs from application cache and check user's IP against it. I've made a simple log of what is actualy happening during each page view, here are the results:
[Code]....
As you see, one request to Login page causes BeginRequest to fire 18 times, there is 18 dictionary loads, 18 lookups etc. That's not the way I want it to be.
Is there any other event that is raised only once per each request? Where do you place the blacklisting mechanism in your applications? I know I can do it through ISAPI filter, but the catch is, this site is on the shared hosting and I'm not sure I can use it on their IIS. Also I'm not sure if ISAPI filter can access some piece of cache with this blacklist (I don't want to load it from DB on each request, that's obvious).
I've created an array of buttons like static Button[] myButtons = new Button[3];
and then creating and adding buttons to my panel like myButtons[i] = new Button();
myPanel.Controls.Add(myButtons[i]);
in my code behind.
How can I handle the events that occurs when a user clicks these buttons, like using OnClick="myMethod" with regular buttons?

I don't want to use Sessions to handle each click event inside treeview selected node changed.Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.

how to handle click event of linkbutton in gridview in asp.net
View 2 RepliesI have a user control that is dynamically added to a placeholder control inside an update panel in my main page. The user control has a linkbutton where I try to handle its Command event. The first time the link button is clicked after the user control loads, the form posts back but the command event handler does not execute, although the user control is still on the screen. The second and subsequent times the link button is clicked it works perfectly. When the user control first loads and I mouse over the link button, the browser status bar says: javascript: __doPostBack('ctl08$lbTest',''). After the first click, when I mouseover the link button the browser status bar shows javascript:__doPostBack('ctl07$lbTest',''). Why the changed in id, I can't figure but it must be why it is not hitting the event handler the first time it's clicked. Here is the cs code that loads the user control:

View 4 RepliesIn my View, there is a HTML button; I would like to execute a function from Controller when user clicks on that button. I need to pass a value from HTML textbox as parameters. My function will do some calculating and return the result back to the same View.
Let's make a simple example.
I would like to input "1" in my textbox, press the button, pass "1" to controller, and in the function, I will do something like 1+1. At the end, I will pass the result, which is "2" back to the View.
