I have created one C# Windows form that have one DataGridView I can add or remove some row from this DatagridView, but now I wonder how can I save my changes, so every time I open my window I can see my added row.
P.S.: I must mentioned that I don't want use any databases, is there any solution?
Is it possible to do that with C# Application settings?
Stick the contents into a DataSet (boo hiss) and serialize that to either a binary file or as XML.
Let's all laugh at the "cutting edge" label of this article:

It won't require a database, just a file.
If you go this route, you could then data bind your grid to this backing DataSet, this will make the process of populating the DataSet with the contents a lot easier.
Yes, you can save it using C# Application Settings, but you need to do some formatting. Hey buddy, even txtfile can be called as database.
All these answers suggest the following:
Create a new class with methods that take your datagrid as a parameter and save it a particular way. One method for saving as CSV, one for XML, etc. Now you can play with with all this w/out breaking your original code during your learning process.
Then you can assess the various methods empirically and decide which is best for you.
The best option I can see is to store this data into disk in XML format. It will also help you to read it back at later stage directly into dataset.
i prefer you can save in xml or csv format to store the app settings, and later you can read through it :) .
