Remove 00:00 from the date

Hi,
I have a column where I get the date value in a gridview. I get the date as like below
26-02-1988 00:00:00
I want to remove the 
00:00:00
from the column.
Here is my code, let me know what should I do ?

 cmd1.Parameters.Add("@dob", SqlDbType.DateTime).Value = txtDateofBirth.Text;
