What is the problem? Please show some code of what you've tried and try to explain a bit better what do you need...I mean, you already know which button is clicked (and in which column) so delete based on that.

How do you want to implement this? either code behind or with JQuery, do you want page postback on button click?
You can get column index by JQuery which starts from 0..

with code

IN GridView RowDataBound event

DataRowView tableData = e.Row.DataItem as DataRowView;
int pos = tableData.GetIndex("MyFieldName");

whenever we click on delete button that column is deleted.don't use field name.some times column name is changed again we go to code and change the column name.no need to do that.
