Hi brothers and sisters, I'm using vb.net 2008 and I have datagridviewVie w with DataGridViewCom boBoxExColumn, and I have to click on the DataGridViewCom boBoxExColumn twice before the options pop up. This is not the case with the ordinary DataGridView combo Box when I changed the EditMode of the DataGridView to EditOnEnter, It works fine with the ordinary ComboBox, but does not work with DataGridViewCom boBoxExColumn. I'm just confused. The main reason why I used the DataGridViewCom boBoxExColumn instead of DataGridView ComboBox is that, the ordinary one could not allow me to type anything even if the DisplayStyle options have been changed. So please help with the single selection with DataGridViewCom boBoxExColumn. Thanks in advance
