Hi @Spideregg , Welcome to Microsoft Q&A.
You need to modify the property of DataGridView.DefaultCellStyle.WrapMode
to DataGridViewTriState.True
.
For example as follows:
dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
dataGridView1.Columns[0].HeaderText = "Student\nname";
Best Regards,
