How to retrive the Deleted Unique ColoumNo in DataTable

 

 

Hi Everyone

      I got stuck wt a problem .My Problem is that I have a on DataTable and i am inserting values in that table wt DataTable.Row.Count and bind that table with gridview.By Mistaken i delete the data from datatable it is deleted from GridView . But i want to maintain the Deleted ColoumnNo.

and the next time when the User Bind data wt grid view it should compare that value with that delete Coloumn .If is dosen't find that value it should bind that bind that value with same ColoumNo

 

For Example 

 

1,aniketh,sharma

2,choudary,d

3,Avin,Chandsanaya

if  i delete the 2 Column and want to insert the next record it should check that Couldmn 2 is Exist or not if it is not then it should bind the data withnew value wit ColounNo2

 

Its urgency

 

Thanks in Advance
