How to bind second Gridview with respect to first GridView

Introduction:-

                  Here I have explained RowEditing,RowUpdating,RowDeleting and RowCommand Events of gridview in asp.net.

Description:-

                  In my previous three article I have explained how to bind a child gridview by selecting a row of parent gridview in asp.net , Different ways to bind data in a textBox from gridview cells by click on select button using both row command and selected index changed event , How to break the text in a gridview .

In previous post I have explained how to bind gridview by selecting a row from another gridview where data retrieves from database but in this example I will explain the same post with different approach without using database.

Here I have created two classes and using list collection binding two gridview.First it wil bind one gridview and by choosing any row data it will bind the another gridview having same record.

Here I am going to provide an example with source code, take a look.
