DataGridViewComboBoxCell Binding - “value is not valid”

Question

I\'m trying to bind separate ComboBox cells within a DataGridView to a custom class, and keep getting an error

DataGridViewComboBoxCell value is not v

Answer 1

use DataError Event handler,

private void shahriartableDataGridView_DataError(object sender, DataGridViewDataErrorEventArgs e)
        {
            //You don't have to write anything here !
        }

and your DisplayMember and ValueMember data type should be the same, in my case I have CountryName for both. Everything works fine for me...!!
