}推荐答案
Since you are already using GridView, then why not use the built-in edit and delete capability it offers.
If using BoundField Columns
[GridView Insert, Edit, Update and Delete – The Ado.Net way]
If using TemplateField Columns
[Adding Rows in GridView with Edit, Update and Delete Functionality]
But of course you always use a combination of BoundFields and TemplateFields based on your requirement.
