where i am wrong how to get the date from text box properly

Answer 1

Try to use a string and convert the string to datetime. like:

 string s="";
s=Request.Form[row.FindControl("txtPLI_MAN").UniqueID];
datetime dt;
dt=datetime.Parse(s);

or

dt=(datetime)s;

and see what happens

At least with this you can debug at each and every step to see the content and see where you are making a mistake
