Submitting the form with ?isdlg=1 must redirect to same page

Hi ,

I am using sharepoint 2013

I am submitting a list data in Newform.aspx by appending isdlg=1. Usually it will redirect to some page but appending isdlg=1 and submitting the form taking me to white empty page.

Eg: https://moss-abc/sites/xxx/Lists/abc/NewForm.aspx?isdlg=1

How can I redirect to same page https://moss-abc/sites/xxx/Lists/abc/NewForm.aspx?isdlg=1 instead of white space.

Please help
