                                  string bu = orgTb.Rows[i]["bu_code"].ToString();
                                  string ar = orgTb.Rows[i]["area"].ToString();
                                  string desc = orgTb.Rows[i]["item_descr"].ToString();

                                      if (Convert.ToDateTime(dateIs.ToString()).ToString()
                                      == Convert.ToDateTime(DI.SelectedDate).ToString())
                                      {
                                          //confirm box
                                          //"record exist. do you want to continue?
  
                                          //if(confirmbox=yes)

Is this what you mean?

if (MessageBox.Show("record exist. do you want to continue?", "Confirm", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
  //Do Something
}
else
{
  //Do something else
}

no sir. :)

i want to loop through rows in datatable first,second compare it if exist(if exist then it will show a message else it will save as new record) thats what i mean sir. :)

I would have come up with the same as Fenrir() from looking at your code. The above is the correct code for your commented out section around a confirmation.

He just has omited code to save the record.

im sorry sir.. my mistake :)

but im not sure sir if c# have a (messagebox.show) .i try it many times..but it gives an error. can you help me in this.. pls. i try javascript in code behind as a confirm box.
here's my code.

 btnSubmit.OnClientClick = "if (confirm('Record already exist.do you want to continue?')) { PurgeCourse(); }";

but i want when i click submit button and if record exist then it will automatically show the confirmation box. in my code you will need to click again the button so that the message will show.

MessageBox.Show() requires it to be a WinForms project as far as I know (there could be ways around it like referencing the right DLLs)

I am starting to guess your project is console or service based?
