When I bind a selected record value from DataGridView to WinForm Controls using C#.net
by this code:

C#

Textbox.text = DataGridView.Rows[e.RowIndex].Cells[0].Value.ToString() // Here Cells[0] for 1st column

When I sort columns the order of rows changes and this code uses RowIndex of
DataGrid. How solve this problem?

Why is this a problem?
It is the designed, expected behaviour.
What did you expect it to do?
What are you trying to achieve that makes you think this is wrong?

Why is this a problem, shouldn't the event handler be giving you the correct row index when it responds to the event the set it off?

Hello,

Have a collection, for example List<test> MyList</test>
And bind it to DataGrid

If you sort the columns, the List will stay unsorted.

C#

Textbox.text = MyList[0].ToString();

If you want to modify the DataGrid, (for example Deleting a record):

(
you must modify MyList instead of it. Then ReBind it to the DataGrid and apply the possible sorting to DataGrid
)

OR

(
Implement the INotifyPropertyChanged. Look at this: INotifyPropertyChanged Interface
)
