asp.net - Return value of ScriptManager.RegisterStartupScript confirm box in code behind -


there 2 confirm boxes on imagebutton - first 1 regular 1 saying "are sure want delete it?" (that onclientclick event on client side ). if 'yes' selected, goes server side code, check happens , if check true, second confirm box displayed code behind using scriptmanager.registerstartupscript.

page page = httpcontext.current.currenthandler page; string script = "alert('there agents associated group. sure want delete group?')"; scriptmanager.registerstartupscript(page, page.gettype(), "its working", script, true);

my question is, how can know value of second confirm box (which generated in code behind) because respect answer have delete record.

any suggestions?

after user confirms delete (the 2nd time), need make second round-trip server pass value server-side.

on form, can add hidden field hold result of second confirm. if hidden field named "confirmdelete", change startup script this:

1) on page, add javascript function prompt user, response, put hidden field , submit again:

<script language="javascript"> function checkconfirm() {    var conf = window.prompt('there agents associated group. sure want delete group?');    document.forms[0].confirmdelete.value = conf; //or equiv in jquery    document.forms[0].submit();  //or equiv in jquery } </script> <!-- don't forget have hidden field inside of form --> <input type="hidden" name="confirmdelete" />

2) change startup script call (above) js function:

page page = httpcontext.current.currenthandler page; string script = "checkconfirm()"; scriptmanager.registerstartupscript(page, page.gettype(), "its working", script, true);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
