All updated values are passed to the Stored Procedure.

A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.

We can't update a record until that record doesn't exist in the input type field (Text Box).

So first we need to move to an updateable row record in the Text Box.

Point numbers 2 and 3 are performed after point 1 is performed.1.

We get the Id value using the row index and another Text Box value is also retrieved.aspdotnet-suresh offers C#articles and tutorials,csharp dot net,articles and tutorials, VB.In this article I will share how to retrieve hidden value from Grid View Column.
