Saving the page as a draft

hi, I'm implementing an e-mail client style web page.

User writes a text into a iframe
[contentEditable = true]


I've a safe draft button.
When the user click's it. I want to save the content of the iframe to a text file on the server. So that, I can load it later again.

So, the compact question is: How to get the content of a iframe from the  codebehind.

Note: iframe is already labeled as runat="server"

Hi tolgaong,

Well, an <iframe> doesn't allow typing of text, so I'm assuming you mean there is a TextBox or <textarea> inside of the <iframe> that you want to retrieve its contents.  So what you'll need to do is create a JavaScript function that access the iframe's TextBox and then stores the contents into a hidden control on the parent page.  This call can occur on the onclick event of the button that's meant to save the Draft.  In ASP.NET 2.0, it'd be the OnClientClick event.  Then in your code-behind you'll simply access the hidden control's Value property and then you're all set.

tolgaong,

This JavaScript works in IE:
document.getElementById("MyHiddenControlID").value = window.frames["MyiFrameID"].document.getElementById("TextBox1").value

Then on your parent page you would have something like:
<input type="hidden" id="MyHiddenControlID" runat="server" />

Good luck!

Let me change the question a bit.
I really have an iframe only.
Then I load a local webpage into this iframe (set src=...)
then, I set the contentEditable property to true. So the user can manuplate the html file. (writes text mostly)
And when he is ready. I want to save the final html

tolgaong,

I can honestly say I've never heard of that contentEditable attribute.  I'm assuming this is an IE only feature?

andycwk, I actually tested that myself before my post and it doesn't work.  I assume since it considers itself another Frame on the page.  Although with this contentEditable attribute, who knows what that produces.

My guess is you'll have to use the same sort of code, except more like so:
document.getElementById("MyHiddenControlID").value = window.frames["MyiFrameID"].document.body.innerHTML;
