There is Standard test box on webform i.e. <asp:TextBox>
There is one HTML button on screen i.e. <input id="button1">
on Button1_onclick(), I want to clear the text entered in text box.
When I run it, It is not recognising text box object.
Note:code is in aspx file only, no code in aspx.cs file.
Check the code below, why <input id="button1"> not recognising <asp:TextBox> in java script:
---------------------------------------------
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="button_postback.aspx.cs" Inherits="button_postback" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript">
// <!CDATA[
function Button1_onclick() {
t1.text="";
}
// ]]>
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
&nbsp;
<asp:TextBox ID="t1" runat="server"></asp:TextBox>
<input id="Button1" type="button" value="button" onclick="return Button1_onclick()" /></div>
</form>
</body>
</html>

I believe that if you created a textbox called t1, then document.t1 MAY work. I dunno, I always use document.getElementById to look up controls. However, either way, you have not created an element called t1. You may want to buy some books on ASP.NET and research the framework you're using.
ASP.NET generates it's own id based on the server side id you provide. You can use the ClientID property of the control in your code behind to get the right id to pass to your javascript. Either way, you should always read your html by viewing source in the browser as a first step to understanding issues like this.

document.getElementById('') works fine if <form></form> are present.
Now my requirement is that I inherit any content template on webform. Due to this, <form></form> is not present now.
I drag drop HTML button (<input type="button") and asp text box(asp:textbox).
Now in java script code, document.getElementById(''); does not work, it is not recognsising asp.net textbox because both HTML button and asp text box are not present under <form>.
So how to achieve in that case.

Why do you need to not have a form ? Do asp: controls work in that case at all ?

There is HTML button (<input type=reset>) on screen.
There is text box (asp:textbox) on screen.
----------------------------------
I have written the below code.
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
Response.Write("hi");
}
Autopost back of text box=false.
Whatever I put in textbox, reset clears it.
Now suppose I make Autopost back of text box=true.
Say enter any text in text box. Now click on say screen. post back will take place, page load will occur. Now I click on "reset", text does not get cleared. WHy?

Because you are not in a form, you have no viewstate, I thought.

Removing the form means that the behaviour of the controls is going to be unpredicatable. Viewstate works on post variables, they get posted in the context of a form. No form, no viewstate. I guess autopostback creates a post that does persist the data.

I'm upgrading a company's website. They are using multiple levels of IFrames to layout their application. I'm able to remove some of the outermost frames and embed the logic into the pages themselves, but some of the child content (displayed in frames) would be rather difficult to merge with the parent frame. Any ideas on a good and simple way to accomplish this? I'm considering putting the child page into a component and hosting the component on the parent page. Not sure if that's the best way to go.

Anything that appears more than once, needs to be a control. Anything that is on every page, or most pages, should be in a master page.

Thanks for the reply, but that's not quite the answer I was looking for. My 'child' pages have a 1:1 relationship with the 'parent' page. So, while it may be a good idea to host the child page as a control, it's not for the benefit of code reuse. Master pages won't solve my problem; either. Again - the 1:1 relationship between parent and child.
Thanks again for the reply.

OK, well, you can break pages up into components if they are insanely compicated, but the resultant plumbing code could well negate any advantage you may get. Breaking your code into regions may help readability if there's a lot of code.

I wanna embed an audio player.....im retrieving location of that song file from querystring which means i can't embed that player in my code behind...i have to embed that player in event handler page.....
image1.AlternateText = Request.QueryString["art"];
image1.ImageUrl = Request.QueryString["imgg"];
label2.Text = image1.AlternateText;
Response.Write("<OBJECT width=312px height=248px clsid:d27cdb6e-ae6d-11cf-96b8-444553540000 VIEWASTEXT&gt;");
Response.Write("<PARAM name=autoStart value=False>");
Response.Write("<PARAM name=URL value='" + Request.QueryString["u"] + "'>");
but the problem is that i used this page under master page...and the content of master page and other code behind contents are not visible only i see this dynamically generated player because code behind content is in content placeholder of master....is there any way that i can embed this player in my code behind but give the value of it's url from querystring....

I don't remotely understand this question. If you generate the HTML in your ASPX or your code behind is TOTALLY irrelevant to the end result. What on earth are you trying to ask ?
Oh, you're using response.write ? To use a content page, I think you need to set up a literal in the page, and set it's content in the code, so that it appears in the right place ( inside the content holder ).

Actually im creating a song site...user clicks the song and the location of that song is picked up from database and sent to the player page in which i want that song to be played...im sending that location value through Response.redirect......so have to be retrieved on player page through Request.Querystring...

Right, so what is the issue ?
What's the legality of the songs you're putting on your site ? Where do they come from ?

hey.. dont write in response using Response.Write... Its not good. Rather place the object tag in the designer and handle from codebehind.
Also if you write
Respons.write("<object width...
It will show you <object. Rather than using < use < itself so that browser renders the html.
Now it is no big deal if you are using masterpage or not. Just in your codebehind if you want to add some reference to parameter to a serverside control, add control.ClientId rather than control.Id.
hope you can do it now.

IM sry....lil' confused... can u write lil' in codes plzzz....
|

coz it's object Tag means html one...not asp so how to add control id property....

Here are your issues. You're trying to create some sort of pirate music site. Which I expect is for your own use, which makes me think that you're trying to pick up a bare minimum of knowledge in order to achieve it. We're not going to write all the code for you. There is no reason for the master page to make any difference. The query string is visible everywhere. In fact, your best bet, IMO, is to set up the player inside your aspx, and have some server tags which cause it to render the right properties from a code behind property, which in turn reads the query string.

what????? Im making site for my college project.....and yeah i don't know much about adding literal controls....coz i hardly use html controls instead i prefer asp controls and i also could have used
mediaplayer toolkit but it's trail i have so wanted to do with html code......???????????

Well, you went all quiet when I asked if it was legal. I appear to be spot on. This is your college project, we've explained exactly how to do it. If you're stuck, post specific code and explain why you';re still stuck. Don't just ask us for code, if you're in college, you can surely understand the explanations we've given ?

i got it....actually i was using Response.Write what actually showing controls in browsers but not master page contents....now using this literalcontrols i did but still problem is that it's not playing the song....n my url is perfectly right........

even i checked still not playing...is it coz im using literalcontrols.....and when im using this code in source it's playing perfectly well
Panel1.Controls.Add(new LiteralControl("<OBJECT width=312px height=248px CLASSID=CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6 VIEWASTEXT >"));
