Events in ASP.NET Page
-
Hi everyone. I'm building a web portal and i have a question. I want to add the content of two TextBoxes in one page and show the result in another textbox, but i don't want the textchange event to make postback because the page has a lot of controls and data. I think i have to make a javascript function for that but i dont know how to raise the events on the client side and i dont know how to pass the controls into the the javascript function so that i can some the values. Thanks programing brothers. :-D

So maybe a google for a javascript tutorial might be reasonable next step...

many option for your question. (1)If you want to add textboxes content on server: Make autopostback property of both the textbox is false. when you submit form the textchange event raise first then button click event raised. (2) If you want to add textbox content in client: Then you must write javascript like this. function add() { document.getElementbyId("Textbox3").value=document.getElementbyId("Textbox1").value + document.getElementbyId("Textbox2").value } you can call this function on lostFocus of textbox2. One thing note down, Asp.net changes the ID and name of the control specailly when master paged are used. Check control ID from output of the page from(view\pagesource)and use that id in place of textbox1 2 or 3.
The miracle is this--the more we share, the more we have.

Cool i understood that thanks, but what about raise events in the client side? I don't want a postback to happen, I wish only to execute an action on the client-side when a textBox is changed. By the way, the textbox is in a FormView, within a UpdatePanel, on a page that has a MasterPage.

If you want to use javascript, my suggestion is use html textbox, menas make it run at server. Now you can find lots of event. You can use control and event like this If you use master pages, Update panels etc the again, first check the name of the control from (view\source)in IE.
