Render Javascript into a WebControl.

R

Ronen

Hi,

I am writing a grid Web control library.

The grid has some client side JavaScript to enable columns resize, sorting,
row selection etc.



I have some problems adding the JavaScript link at the render of the
control:



1) During the render method of the control I need to add the following code:

<link type="text/css" rel="stylesheet" href="includes/WLGrid.css" />
<script type="text/javascript" src="includes/WLGridSort.js"></script>
<script type="text/javascript" src="includes/WLGridLib.js"></script>

I need this code to be rendered in the Head section of my page and NOT
in the control section.



2) In Case user put two controls on the page I want the JS code to appear
only once in the <Head> of the rendered HTML.



Thanks,

Ronen

Ronen,

I don't it is possible to emit markup from a control directly into the HEAD
element of the page. Your alternatives are either hard-coding these lines
into the page or coming up with a send/receive solution that would involve a
control, located in HEAD element. That control will be your receiver and the
grid will be the sender.

..net does not directly support this, and you are stuck if the page does not
have a <head> section. if it does, scan the Page.Controls collection of
objects before the form object, check the generice html controls innerhtml
of the control for the <head> statement or (if user added a runat=server on
the head> a control with is tag), then update the inner html with your code
(if it is not already there).
