Client Side Scripts

A

Arfin

Any Response.Write("Something") that I put on the Page_Load of a Web
User Control gets "printed" on the page before the first <html> tag.

How can I programmatically add some html scripts to a control without
using the Page_Load?

On the same line. Is there a way from the [MyControl].ascx (the html)
to access variables created in the [MyControl].ascx.vb (the code)?

Use Page.RegisterClientScriptBlock to add script to the output of the
page. You can also call Page.IsClientScriptBlockRegistered to prevent
registering the script twice.

You can expose your fields/variables as Protected properties and access
them from the ASCX file.

Click to expand...

If you want to *programmatically* add script, you're going to have to do
it somewhere in the code-behind class. There are methods in the Page
class to assist with injecting client-side script as Drew mentioned:
Page.RegisterStartupScript() and Page.RegisterClientScriptBlock()
