expected behavior below

here part of code gridview being created , populated.

        //child name column         datagridviewtextboxcolumn namecolumn = new datagridviewtextboxcolumn();         namecolumn.name = "cname";         namecolumn.headertext = "child name";         namecolumn.datapropertyname = "cname";
