DataGridView Cascading ComboBox displays black color backcolor in 2nd combobox

I have winform application with DataGridView and there I am using Cascading ComboBox. For example column 1 has one ComboBox and value of column 2 combobox depends on column 1 selection. Everything seems to be fine but when i open 2nd combobox then its backcolor gets black. See the screenshot. I am not setting backcolor anywhere (in design or code). Any idea why this strange behavior? sceenshot

I am binding 2nd ComboBox in EditingControlShowing event of DataGridView. If i bind that in FromLoad event then it works fine.

it's an old post but someone might need this like me. Why not try:

cmbBox.SelectionChangeCommitted += new EventHandler(comboBox_SelectionChangeCommitted);

instead of:

cmbBox.SelectedIndexChanged += new EventHandler(comboBox_SelectedIndexChanged);

In combobox DropDown event I am setting BackColor = Color.White;. So its a workaround I found for now. Any other solution is welcomed.

Check the DefaultCellStyle of the column. It's the only place I see where I can duplicate the blackness.
