Sorry Chris, I might be asking similar type question earlier also but this is final summary.
Suppose we have designed a master page. Say we keep nothing in it.
We inherit it in a webform.
Now I have observed the following. Please confirm,reply also:
1. <form> /<form> is not present.
HTML Reset button works fine.
Document.getelementbyid-> does not work because form is not present.
2. In web form where i have inherited master page, I keep one html reset button and standard asp text box.
If autopostback of textbox=true then
whatever we enter in textbox and click on reset, page load occurs.It will retain the values. Now value from text box will not be cleared after clicking on Reset. Because reset sets it back to inital value (that we got after page load).
If autopostback of textbox=false then
whatever we enter in textbox and click on reset, value will be cleared.
3. In my requirement i have inherited master page in web form as mentioned above.
It's requirement to keep autopost back of textbox=True.
Now reset will never clear the values of text box.
In that case, if i use simple HTM button (not reset) and try to write the following code, it does not work because <form> is not present. So document will not be identified.
function ResetForm(){
var elems = document.forms[0].elements;
for(var i=0;i<elems.length;i++){
elems[i].value = "";
}
}
So in webform (using master page), how to clear the values of text box on clicking of button.
Note: document will not work because <form> is not present.
autopost back will be true for text box because we have to trigger event TextBox1_TextChanged1 also.
TextBox1_TextChanged1 will not work without autopostback.
So plz tell me solution.

your page is broken if this is true

Because you don't have a form

Correct

PUT A FORM ON THE PAGE !!!!
And don't post a new question when your old one is still visible, and you're asking the same thing.

I have inherited master page. Now I will have to paste controls on Content.
Can we still post a form, there is so speciic control as such

Your master page defines the form, if it's written right. The content pages go inside the form. An ASP.NET page should only have one form on it.

Hi To,
I Want to count visitor no of our site and also display it in my site by which user can see his visitor no of site.
for which I have written this code in globle asax in application start event and show it in the master page.
but the value is reset every time.
The code is ..
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Application("visitor") = 1
End Sub
and the code of session_start is..
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
Application("visitor") = CType(Application("visitor"), Integer) + 1
End Sub
and
display it in the form load int master page
Me.Label1.Text = "Visitor No " + Application("visitor").ToString()

Of course you don't call it Label1, right ?
Of course it's reset. EVery time the application is. You need to persist it somewhere for it to never reset, like a text file or a DB.

Well, that's what I just told you to do, didn't I ? Which bit are you stuck on ? If you've written a website that is likely to care about a visit count, surely you know how to use a database, or a flat file ?

This code is for current visitors on site if you implement Session_end event too. If you are trying to count total visitors you must use a database or any kind of data storage
|
|
|
|
|
As Christian said, on application start get that text file/DB to display total number of visitors and on session start get that value,add 1 and save back.

it's very easy process you may go now this url http://www.amazingcounters.com
And Chose Your Visitor Counter Designed & Copy the code or Add ur Site master page...................

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.
