Two ways:
1. In ASPX if the columns are defined:

HTML

<asp:BoundField DataField="MyProperty" HeaderText="Int" InsertVisible="False" ReadOnly="True" />

2. In code behind file:
To make the column readonly on editing add this

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
   // Find the column and set it readonly
   BoundField bound = GridView1.Columns[1] as BoundField;
   bound.InsertVisible = false;
   bound.ReadOnly = true;
}

Generally, we define the columns of a grid and option 1 should do just fine.
