Extra Column in DatagridView C #

Set RowHeadersVisible

to false.

dataGridView1.RowHeadersVisible = false;

      

        
        
        
      

    

(I know his name is pretty misleading, but it works :))

For the following code:

dataGridView1.RowHeadersVisible = false;
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Address");
dt.Rows.Add("ABC", "DEF");
dt.Rows.Add("XYZ", "DEF");
dt.Rows.Add("EFG", "HIJ");
dataGridView1.DataSource = dt;

      

        
        
        
      

    

You will get this:

Without this property set to false, it will look like:
