In my application I use System.Windows.Forms.DataGrid (not DataGridView!) Unfortunately, I cannot change ColumnHeadersHeight - there is no such property for this control. And secondly, if I increase the row height,  text is aligned to the top of row, but vertical alignment is needed. Is there any solution to this problem?

//Create FileInfo

FileInfo info = new FileInfo(path);

//Set Access rules

security.AddAccessRule(new FileSystemAccessRule(identifier, FileSystemRights.FullControl, AccessControlType.Allow));
