I know this is old, but for those surfing this question, the answer by MUG4N will align all columns that use the same defaultcellstyle. I'm not using autogeneratecolumns so that is not acceptable. Instead I used:

e.Column.DefaultCellStyle = new DataGridViewCellStyle(e.Column.DefaultCellStyle);
e.Column.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;

In this case e is from:

Grd_ColumnAdded(object sender, DataGridViewColumnEventArgs e)

To set align text in dataGridCell you have two ways:

Set the align for a specific cell or set for each cell of row.

For one column go to Columns->DataGridViewCellStyle

or

For each column go to RowDefaultCellStyle

The control panel is the same as the follow:

you can edit all the columns at once by using this simple code via Foreach loop

        foreach (DataGridViewColumn item in datagridview1.Columns)
{
item.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
}

DataGridViewColumn column0 = dataGridViewGroup.Columns[0];
DataGridViewColumn column1 = dataGridViewGroup.Columns[1];
column1.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
column1.Width = 120;

While we are dealing with alignment and configuration it can be useful to reduce repetitive tasks by using (C#) anonymous types. Much easier to read and advanced operations can be edited in one place. Like in this datagridview dg configuration

foreach (var conf in new [] {
new { Col = 0, WidthPercent = 40, Align = DataGridViewContentAlignment.MiddleCenter } ,
new { Col = 1, WidthPercent = 30, Align = DataGridViewContentAlignment.MiddleCenter } ,
new { Col = 2, WidthPercent = 30, Align = DataGridViewContentAlignment.MiddleCenter }
})
{
dg.Columns[conf.Col].Width = (int)(dg.Width * conf.WidthPercent/100);
dg.Columns[conf.Col].DefaultCellStyle.Alignment = conf.Align;
}
