DataGridView.AllowUserToAddRows customisation
Apologies if this has already been asked but I cant see that it has been.
A Winforms DataGridView has an 'AllowUserToAddRows' property. Is there a way to ensure a new row is only added if certain conditions are met?
For example, I have a DataGridView with two columns, the first is a TextBox column, the second a ComboBox column. The 'AllowUserToAddRows' property is set to true.
However, I wish a new row to be added only if the user has entered a positive number in the TextBox column and made a selection from the ComboBox column. Currently a new row is added when anything is entered in the TextBox column, or if a selection is made in the ComboBox column.
Many thanks in advance

Yes, there is. It's called validation.
