Call a javascriptfunction in PageLoad event

How can I call a javascript function in my codebehind PageLoad event???

You can use RegisterClientScriptBlock for this...

Sub Page_Load( sender as Object,e as EventArgs)

'Form the script that is to be registered at client side.
Dim scriptString as String = "<script language=JavaScript> "
scriptString += "alert('Welcome to Microsoft .NET')<"
scriptString += "/"
scriptString += "script>"

If(Not IsClientScriptBlockRegistered("clientScript"))
RegisterClientScriptBlock("clientScript", scriptString)
End If
End Sub

OR

You can simply call the function using <body onLoad="YourFunctionName()">

To be more specific you will need to use the

RegisterStartupScript and IsStartupScriptRegistered

Sub Page_Load( sender as Object,e as EventArgs)

'Form the script that is to be registered at client side.
Dim scriptString as String = "<script language=JavaScript> "
scriptString += "alert('Welcome to Microsoft .NET')<"
scriptString += "/"
scriptString += "script>"

If(Not IsStartupScriptRegistered("clientScript"))
RegisterStartupScript ("clientScript", scriptString)
End If
End Sub

Dim popupScript As String = "<script language='javascript'>" & _
"window.open('PopUp.aspx', 'CustomPopUp', " & _
"'width=200, height=200, menubar=yes, resizable=no')" & _
"</script>"

Page.RegisterStartupScript("PopupScript", popupScript)

function myFunction() {
.
.
.
}

and in pageload event i need to call this function, as something like this:

Response.Write("javascript:myFunction()")

but it doesn't work, and I have tried I lot of alternatives....
