Hi Ravi,

Assuming that the prpperties FrbId,ReceivedFrom,ReceivedDate... etc are in class "Transaction" its collection "TransactionList" is acting as ItemSource for the grid.
You can try the following code in button_Click event.

foreach(Transaction txn in TransactionList)
{
bool bChkboxValue = txn.FrbId;
.....
....
}

Is this what you want?

Thx!
Swaps....

In other terms:
You always need objects that the datagrid can bind to, also for a check box column. You need a boolean property you can bind your check box column to. Then just query your objects to see if they were checked.
You should not access the data grid cells in any way to get values - that is ugly :-)
