<asp:BoundField DataField="flag" HeaderText="flag" SortExpression="flag" />
<asp:CommandField DeleteText="Exclude" ShowDeleteButton="True" ButtonType="button"></asp:CommandField>//when boundfield "flag" is true, the deleteText of commandfield should be 'Exclude', otherwise, it is 'Include'
 </Columns>
    </asp:GridView>

Button btn = e.Row.Cells[2].Controls[0] as Button; //May be index 1,2,3,4,5,6,7 who knows...
if(drv["flag"].ToString() == "1")
{
    btn.Text = "Exclude";
}
else
{
   btn.Text = "Include";
 
}

This worked for me
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                DataRowView drv = (DataRowView)e.Row.DataItem;
 
                Button btn = (Button)e.Row.Cells[2].Controls[0];
 
                if (drv["flag"].ToString() == "1")
                {
                    btn.Text = "Exclude";
                }
                else
                {
                    btn.Text = "Include";
 
                }
            }
 
        }
