I tried thus tutorial with edit but I failed
I wrote the tutorial you mentioned a long time ago. I've published a new article and put together editing and saving of records here:
Dynamically Adding and Deleting Rows in GridView and Saving All Rows at Once[
^]
That should help you get started. Please note that if you have a different structure within your
TemplateField
column, you need to debug your code so you will know how to reference the controls within the grid.
