rodchar,
To do this you need to display the alert from the BODY tag's onload method.
OnLoad can be a bit of a pain to handle correctly, especially if you have 2
or more bits of code that need OnLoad handlers, not to mention cross browser
support.
Here's a chunk of code I like for onload (handles multiple onload handlers
and is cross browser compatabile):
//
// Add the addLoadEvent function
// - A clean cross browser method to add a window.onload method
//
ClientScript.RegisterClientScriptBlock(this.GetTyp e(), "addLoadEvent",
"function addLoadEvent(func) { var oldonload = window.onload; if (typeof
window.onload != 'function') { window.onload = func; } else { window.onload
= function() { if (oldonload) { oldonload(); } func(); } } }", true);
More or less the above checks if there is an existing OnLoad handler. If
there isn't then the function passed as the argument is used. If there is an
existing onload handler then a new function is defined that calls the
existing onload handler and then calls the function passed as the argument.
This new function is then setup as the onload handler.
With that javascript function defined,you can then add as many onload
handlers as you need. To display an alert after the page has fully loaded:
string ShowMyAlert = "addLoadEvent(function() { alert('hello'); });";
ClientScript.RegisterStartupScript(this.GetType(), "ShowMyAlert",
ShowMyAlert, true);

throw
up an alert. it works fine but that it throws the alert before the entire
