If you have a look at this code once...

RegularExpressionValidator regEx = new RegularExpressionValidator();
regEx.ID = "RegularExpressionValidator1";
regEx.ControlToValidate = "txtAnswer";
regEx.ValidationExpression = @"\d{2}\/\d{2}\/\d{4}";
regEx.ErrorMessage = "Date is not Valid";
regEx.SetFocusOnError = true;
gvr.Cells[3].Controls.Add(regEx);

after occurring validation the value will be added to gridview...because of you mentioned this code....

gvr.Cells[3].Controls.Add(regEx);

so separate this functionalities..
