Onclientclick in the aspx page, and response. Write ("") in the CS code

In the button, <asp: button id = "lbltoinvoic" runat = "server" onclientclick = "fff () "cssclass =" btn2 "text =" invoicing "onclick =" lbltoinvoic_click "/>

Then, write <script language = "JavaScript"> function fff () on the top ()
{

}

And write in the CS file: protected void lbltoinvoic_click (Object sender, eventargs E)
{
..
Response. write ("<SCRIPT> commandid dialogarguments000002.16.doc ument. getelementbyid (window. dialogarguments [1]). value = \ "" + strvalue1 + "\" too many logs into dialogarguments%0%.doc ument. getelementbyid (window. dialogarguments [2]). value = \ "" + strvalue2 + "\" too many logs into dialogarguments%0%.doc ument. getelementbyid (window. dialogarguments [3]). value = \ "" + strvalue3 + "\" too many logs into dialogarguments%0%.doc ument. getelementbyid (window. dialogarguments [4]). value = \ "" + strvalue4 + "\"; window. close (); </SCRIPT> ");

}

Is the same.
The code location is different.
