WebControl with CSS and Javascript

[patrick.sannes]

Hi there,

I'm creating a custom control with Javascript and CSS. It will be a
nice overlay calendar with a result textbox. My main problem is that
the Javascript is realy huge, so you want to include it in a seperate
..js file. But, then it is not bound with the WebControl.... What is the
normal way to solve this??

Regards,
Patrick

You can embed the javascript file into the control assembly as an embedded
resource if you like.
Depending on which version of the framework you are working with , you can
get this out with GetManifestResourceStream.

the standard way is:

RegisterClientScriptBlock("mycontroljs","<script
src=\"mycontrol.js\""></script>");

or the new

RegisterClientScriptResource(typeof(this),"mycontrol.js");


both of these methods handle being called more than once so that the
<script> tag is only output once. they also have methods to determine if
they have been called already for the same tag.

I did it with this peace of code I found, but then I get it inline (and
it is a lot, so it would be nicer to get it in a .js file... I realy
don't know if it is possible...

private void RegisterScript(String scriptName)
{
if
(!this.Page.ClientScript.IsClientScriptBlockRegistered(scriptName))
{
using (System.IO.StreamReader reader = new
System.IO.StreamReader(this.GetType().Assembly.GetManifestResourceStream(this.GetType(),
scriptName)))
{
String script = "<script language='javascript'
type='text/javascript'>\r\n<!--\r\n" + reader.ReadToEnd() +
"\r\n//-->\r\n</script>";
this.Page.RegisterClientScriptBlock(scriptName,
script);
}
}


}

Solved it...

Added
[assembly:
System.Web.UI.WebResource("Company.WebControls.popcalendar.js",
"text/js", PerformSubstitution = true)]
To the AssamblyInfo.cs
And
string scriptLocation =
Page.ClientScript.GetWebResourceUrl(this.GetType(),
"Company.WebControls.popcalendar.js");

Page.ClientScript.RegisterClientScriptInclude("Company.WebControls.popcalendar.js",
scriptLocation);
To the WebControl class.
