print div content from user control without opening a new window

I have a USER CONTROL with a <开发者_JAVA技巧div> tag and a button. I want to print the content of the <div> when the button is clicked. Only the content of the div and nothing else no matter where the control is used. This without opening a new window. I cannot find a solution that works with every browser!

Thank you!

You might be able to generate a CSS file that excludes everything except the <div>, something in the lines of:

<link rel="stylesheet" type="text/css" media="print" href="print.css" />

And the putting something like this in print.css:

* { display: none; }
#specialdiv { display: block; }

In the server-side click handler of the button, send out the content you want to display:

protected void MyButton_Click(object sender, EventArgs e) {
    Response.Clear();
    Response.Write(...the content of your div; be nice and add at least some html headers...);
    Response.End();
}

Clear removes everything from the output buffer, Write outputs your stuff and End stops processing the rest of your page.

As kb said, use css to define what is and what isn't printed on a page. If you want a print button which prints just a div follow kb's instructions. If you still want file->print to behave as normal however, change the page's (media="print") css prior to calling window.print() and revert it afterwards in the button's onclick function.

Sorry to be the bearer of bad news but there isn't a comprehensive print api for javascript!
