I thought the MaskedTextBox column would be the last addition for the DataGridView but it seems there is more interest in columns than I anticipated. I was trying to think of other useful ones. Would a column for editing a colour be useful? Does anyone actually need to do this at the moment? What data type is the column itself?
Apart from a drop button and colour column what others are people in need of? I cannot promise to add what people request but if it sounds generally useful and not overly time consuming to add then I will certainly consider it.
