QUESTION
I need to insert a JS in the Head section when I render a
control but if I use RegisterClientScript it write in the
body section.
The only way I found is to get the head element and then
add the script manually, there is another way ?
ANSWER
I haven't found any ".NET" way to do this, though I will look into it
further tomorrow.
So far, I've found two ways to prepare the code in the code-behind and get
that code to execute from the <head> section.
1)
In the code-behind, inside the "class", but not inside any function,
declare a "protected" string similar to this:
Protected s As String = "<script>a=5</script>"
Then, in the <head> section of your page, add this:
<%=s%>
2)
Use the regular code-behind register functions to create your script.
However, write it as a function, such as:
<script>
function abc() {
....
}
</script>
Then, manually add a call to this function in the <head> section, such as:
<script>
abc();
</script>
---
Both of the above require you to manually insert something into the <head>
section. However, they do allow you to create the body of the script in the
code-behind. This could help if you need to adjust the content of the
script block via the code-behind.
I'll let you know what else (if anything) that I find out tomorrow.

ANSWER
I did not find any way to have the code-behind insert script into the
header section of the HTML output. It always went into the body section. I
think that leaves the following options:
1) Type your script into the ASPX page rather than the code-behind.
This can be done a couple ways. You can type all the script into the HTML,
or you can just type a function call into the HTML (it would have to go in
the onload event so that it doesn't run until after the rest of the page is
rendered).
2) Use RegisterClientScriptBlock which puts the script at the TOP of the
body block rather than in the head block.
