Hi
How I can set ColumnType to MaskedTextBox in DataGridView?

I believe a maskedTextBox is a bit of an old fashioned kind of UI style of programming. Use Validate and Validating events if you want to check the input in a TextBox or use a DateTimePicker for a date.

you are right but i want check my date in grid columns how i can do it by Validate or validating?

[ddanbe]

Make a DateTimePicker control in one of your columns see how to do it here
That way your dates are always of the correct format and you don't even have to implement the Validate events.

for solving this problem can we use "DefaultCellStyle.Format"?
for example:
dataGridView1.Columns[5].DefaultCellStyle.Format = "yyyy/mm/dd";
