Answer / guest

Here, bind primary key of database to datagrid column make
it visible false.
and travel loop as

foreach(DataGridItem dataItem in DataGrid1.Items)
{
priceText = (TextBox)dataItem.FindControl
("txtBookPrice");
bookIdText = (TextBox)dataItem.FindControl("txtBookId");

Updatecode_for_perticular_row ();

}

txtBookPrice= textbox from witch u would like to update
txtBookId= test i.e. unique id comming from database

With help of unique id in for loop find perticular text in
texbox and update.

This code you will write on update button click.

Answer / pradeep

Each row is having Edit/Update/Cancel button.
In "_UpdateCommand" event, we can write a code to update
directly into the database. But it is not good practice.
For updating whole records in a single event, we need to
have hidden column for updateflag and while updating we can
store the updated data into session. By using BUTTON
control out side of datagrid, we can find only 100 records
(updated records) based on updateflag and we can update
only those records into DB.
