Hi there,
Well I know I was able to do something like
Response.Write "<script>alert('Your search did not return any
records!');</script>"
from my asp page in Visual Interdev. Now I'm using .NET and this still
works but how do I call custom-made javascript function, which is in my
html part of page from code behind? I tried something like
Response.Write("<script language='javascript'>ShowHide('NewError')
</script>")
but it gives me an error something like object required.
Thanks a lot guys!

Bob-
I found one way of handling this.
I created a function in the code behind page which returns a string
containing the script tags and all the script code.
In the HTML page I coded
<%=functionName%>
where I wanted the script to be in the HTML.
If someone knows a way to handle to this without the old school ASP tag, I'd
be interested as well.

one way to do it is to use a LiteralControl.
I'm not sure *exactly* what you're asking, but in the past I've placed an
<asp:PlaceHolder> on the page, then added a control (in this case a button
that fires off javascript) to the placeholder from the codebehind, at
runtime.
in the aspx page:
<asp:PlaceHolder Runat=server Visible=False ID=phBtnClose></asp:PlaceHolder>
in the C# code behind:
//declare your placeholder
protected System.Web.UI.WebControls.PlaceHolder phBtnClose;
//add anything you want into the placeholder... in this case, a button.
phBtnClose.Controls.Add(new LiteralControl("<input type=button value='close
window' onClick='javascript: CloseWindow();' class=smButton>"));
basically, the codebehind renders a button on the client side - the button
click event references javascript that is already on the client side.
make sense? did this help?

Bob
You may also want to consider using the classes,
Page.RegisterClientScriptBlock and Page.RegisterStartupScript to create
client side javascript. There are good examples at:
http://www.dotnetjunkies.com/tutorials.aspx?tutorialid=438
and
http://www.dotnetbips.com/displayarticle.aspx?id=106
Good luck
John

John,
I can't speak for Bob, but thanks.
One more step in my rehabilitation from old school ASP tags...

Check out these examples.
http://www.aspalliance.com/aldotnet/examples/cd.aspx
They show how to pop up a javascript confirmation window from an ASP.NET
DataGrid control.

I want to thank you all for you replays. John's suggestion worked for me
and I think it's the most elegant and proper way of doing it. Once again
thanks a bunch guys!
Cheers,
Bob
