winforms - DataGridViewComboBox dropdown size on multiline -

i have datagridviewcombobox in datagrid. 1 of other columns allows multiple lines of text entered.

my problem dropdown in datagridviewcombobox expands fill cell. dropdown 1 line.

here examples: http://imgur.com/qx4wsuk. in example, first column's dropdowns should 1 line, , not fill whole cell.

you need set cell style's alignment , display style:

var datagrid = new datagridview();  var combobox = new datagridviewcomboboxcolumn();  combobox.defaultcellstyle = new datagridviewcellstyle { alignment = datagridviewcontentalignment.topleft};  combobox.displaystyle = datagridviewcomboboxdisplaystyle.combobox; 

msdn on datagridviewcontentalignment
