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 / arief

First you load 20 records to DataGrid and add one
more templet field like"Chech Box" finally add one button
in your page for update operation

you write code whatever CheckBox clike get all row
id's and you can update row based on selected id's

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.

Answer / masuduz zaman

By using dataSet.GetChanges(DataRowState.Modified) method we can update all 100 records at a time.

Where would you use an iHTTPModule, and what are the limitations of any approach you might take in implementing one
