There are many ways you can do this. One way is to handle the TextBox.Validating event (inherited from Control) of the DataGridTextBoxColumn.TextBox property, which gets the TextBox that is hosted when the cell is in edit mode. If you wanted to validate input as they type, handle the KeyDown event of the TextBox as well.
