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.
