I made a webform in html and I have a website in C#.
I would like this form to show up every time the page is loaded.
What is the best way to integrate/include/call the form?
Which pages I have to modify? Default.Aspx or Default.Aspx.cs?
The purpose of this project is to show this form everytime the cookies is not set in the aspx code.
Which I guess I have to modify the aspx part that checks if the value of the cookie is set or not and show/not show the webform based on this value.
You could do this using a combination of JavaScript (to check if cookies are enabled) and JQuery. If cookies aren't enabled, have a placeholder DIV that can hold the HTML content you wanted to show. Then use $.ajax (http://api.jquery.com/jquery.ajax/) to load the html content from browser and set the DIV's innerHTML property with the returned HTML.
Hope this works for you!!
Some little progress.
That's how I modified my pages for my needs. In this way the html webform is diplaying correctly.
In the head of default.master I added:
in the default.aspx I added:
with the entire html of my html page (tag html included).
Now I need to modify this page that in the way this pop up is showed only if a cookie value is not set.

I want to assign the html content to iframe control from asp.net code behind page;
this is working fine
myIframe.Attributes.Add("src", "pathtofilewith.html");
but, i don't want to give the path of html file to display i just want to assign some html content which comes from database to iframe control.
i want some thing like this(Ashok) to be displayed in iframe control
i tried the bellow ways but nothing is succesful
myIframe.Attributes["innerHTML"] = "<h1>Thank You..</h1>";
myIframe.Attributes.Add("innerHTML", "<h1>Ashok</h1>");
A way to communicate between two different pages where one is in an IFrame on the other, is to post data using JQuery. An example is given in this StackOverflow question
It is also discussed in this other StackOverflow question
On this page, you will also find a short and simple example of how you can put content in an IFrame without using a separate web-page for it (note the lacking src attribute!).
Hope some of this helps!
You can't. That's not how an IFRAME works - it is for use with the src attribute as you've already discovered.
Perhaps you want to create a DIV instead
There is no way to insert HTML content into iframe tag directly, but you can create a page which gets the content form the database and then you can view it using iframe,
or
You can create a page for example called getContent.aspx which request value from the URL e.g. getContent.aspx?content=<h1>Thank You..</h1> and display it wherever you like, and then call it from iframe.
I want to show a web page within another web web in asp.net. I have a page named home.aspx and a page name add.aspx how can i do this.
if you just want to load contenct than make use of jquery ajax function or noraml ajax to load data in you page
Example
$("#result").load("AjaxPages/Page.aspx", function () {
alert("Page.html has been loaded successfully!")
});
Use iframes. Pleace for example this code inside the homep.aspx. This is only the idea, find how to show it with out border and with out scrool bars, and also how to fit it in place.
<iframe src="add.aspx"></iframe>

ajax and iframe
Use ajax if you have some informations only to show. Use iframe if you also need independend post backs that enters data.
ajax is better if you care to have only one page, not working with out javascript, and maybe you need to add more ajax to make more thinks with the data that you get.
iframe is fast, but 'dirty' because is not seo friendly, a user can open content from iframe alone, etc.
I have a page that does not have runat="server" set in the <head/> section. I do not have access to modify any of the code in the page.
This page contains a user control which I do have access to. Can I add a <meta/> tag to the head section of the page from the user control? It needs to be server-side so a javascript solution won't work.
One option is to create a Response Filter, and then modify the output before it's sent to the user.

You can parse the text in
(this.Page.Controls[0] as LiteralControl).Text
to see where the string <head> starts, and insert whatever text you need in there thus injecting your own code into the page header without it being marked with runat="server".
Please be aware though, this is pretty hacky way of getting your code where it most likely shouldn't be (otherwise the <head> element would have been marked as runat="server" so you can access it normally). This will also break if at a later date the head element is changed to be an ASP.NET control. It might will not work with master pages, you will have to walk up the control tree looking for topmost literal element.
i have made a page in asp.net, i have a costing calculator which has more than 50 fields, dependent on each other, one is the result of previous two and like that, i want my page to be printed in a well manner, and the header of the page which is in master page should not be in print, also the color schemes i want to adjust, let me know the best solution for this which .net provides
Put the content inside <div id="divid">YOUR CONTENT NEEDS TO BE PRINTED</div>
Then call the javascript function on button click which will print the selected area or only html of div. pass the id of div on calling javascript function.
function CallPrint(var strid)
{
var prtContent = document.getElementById(strid);
var WinPrint = window.open('','','letf=10,top=10,width="450",height="250",toolbar=1,scrollbars=1,status=0');
WinPrint.document.write("<html><head><LINK rel=\"stylesheet\" type\"text/css\" href=\"css/print.css\" media=\"print\"><LINK rel=\"stylesheet\" type\"text/css\" href=\"css/print.css\" media=\"screen\"></head><body>");
WinPrint.document.write(prtContent.innerHTML);
WinPrint.document.write("</body></html>");
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
return false;
}
Call CallPrint('DivGrid');" on onclick() of button or use below: but.Attributes.Add("OnClick", "return CallPrint('DivGrid');");
Nothing to do with .Net and everything to do with a print stylesheet. You can create a stylesheet which will only work for when the page is printed. And you can change everything from what displays to postion to colours.
Use:
<LINK rel="stylesheet" type"text/css" href="print.css" media="print">
Note media="print" means it'll be used for printed pages.
I know that question has been asked a long time ago, however there is no accepted suggestion. So here my approach for friendly print version when using Master page.
Create an empty master page (PrintVersion.Master) to serv as print version. Add what ever you need to be print (like logos) if anything to that master page.
from your content page, add a print link with target blank. Make the href to load the current page. From the href add a querystring so you can capture it from your content page preinit event.
From your content page preinit event detect if the querystring to print exists, then specify the blank master page like: MasterPageFile = "~/Ful/Path/of/your/PrintVersion.Master"
Optional, on the PrintVersion.Master on document.ready call: window.print(); The browser print dialog will automatically open.
You can make a new printable page version, which doesn't include a header. This version can also have the layout you need.
I have a master page with one form on it. It is a search form which must always be visible. When the button of that form is clicked I want the form data to be sent to search.aspx. The problem is, I don't know how. I cannot set the form action to search.aspx, because all my other pages which use the master form will go to search.aspx. This I don't want.
Hope someone can help me out :)
Thnx.
In order to pass the values of the control "txtSearch", when Server.Transfer is executed, you could do many things, including passing it via a querystring variable or setting up a session variable, and then check either of those in the Page_Load event of Search.aspx, and if it's populated, call the event that is fired when the user would hit the submit button on the Search.aspx page.
Also, if the Search.aspx file is using the same masterpage, then you can use this.Master.FindControl("txtSearch") to get the control (it you look a the source of the file after it is generated in the browser, you'll notice that controls in the master page aren't really called by their ID, rather that have something appended to them (i.e. it would now possibly be called "ctl00_txtSearch")
You could create your search form in a separate form, and get it to use GET instead of POST.
Either that, or have the master form handle the search button click and use Server.Transfer to go to the search form.
You can have multiple forms in one page I believe. So one form (your search form) would have its action set to search.aspx and the other would be set for the page itself.
ASP.NET webform pages only have one form (which would generally be included on the master page). You can set the postback url for the search button to your search page..
<asp:Button ID="btnSearch" runat="server" Text="Search" PostBackUrl="~/search.aspx" />
..or just redirect to it from the handler in your master page like this:
protected void btnSearch_Click(object sender, EventArgs e)
{
Response.Redirect(#"~/search.aspx?q=" + Server.UrlEncode(txtSearch.Text));
}
..or use Server.Transfer as suggested by David Kemp.
Note: If you use Request.Query[#"q"] on your search page to get your query, you don't need to use Server.UrlDecode() - it's done for you.
I would:
Add some code to the master page code-behind to detect the source of the POST.
Once I have the source of the POST (e.g. the Search box). I would then pass its query to the Search form.
I used a similar process with having a HTML login form on the master page.
I posted a question and subsequent solution here - check it out:
Form Elements in ASP.NET Master Pages and Content Pages
Once I got my head round it, it seemed a pretty simple and reasonably elegant solution.
The benefit of this is that you have complete control over how the data is sent to the search form. And you don't need to enable transfer of form data to the search form and all that nasty stuff, just create a new GET request to the search page and let it do what it is supposed to do :)
Hope this helps.
NOTE:
You can only have one form with runat="server" on an ASPX page. Additional forms MUST be HTML FORMS.
Because your search form is in the master page, you can probably structure it to contain 2 forms. Place the search form tags with the action set to "search.aspx" outside of the tag that is used by the rest of the site.
<body>
<form action="search.aspx>
<!--search box and submit button-->
</form>
<form runat="server">
<!--rest of page inc placeholder-->
</form>
</body>
If the structure of the page will not enable this, you can set the submit button's PosbackUrl to point to "search.aspx". In this case, "search.aspx" would need to be coded to look in the PreviousPage property for the form data, or use Request.Form to access the input.
