You can do it in CellValueChange d event;

As a parameter you'll get DataGridViewCel lEventArgs which has ColumnIndex and RowIndex properties
- this will point you to the cell changed;

then you can call your validating function and, if needed, reassign/reset the value of that cell (DataGridViewCe ll.Value)

I'm sure there are other ways to do this, but it worked for me

afaik, there's no Date format to be specified for a DataGridView

unfortunately or rather fortunately;) I was wrong about this one:
there's no datacolumn type as such, but you can specify content type to whatever is valid for you, e.g.:

DataGridViewColumn column;
column = new DataGridViewTextBoxColumn(); // here you specify what does each cell look and behave like, check documentation for other "looks"
column.Name = "colName";
column.HeaderText = "header text";
column.ValueType = Type.GetType("System.DateTime"); // this is the Date type; you can use (probably) whatever type you want, just remember to put full path to the type
dataGridView1.Columns.Add(column); // add the column to your grid

hope this helps
