if dateTime is datatype used in database

Then put a if condition by checking not null value and if it then assign the value to date control otherwise don't assign. Thanks

I have used Date Control

You can check if that column value is not equal to null then bind the value otherwise not. But that date column you are binding to which control?

id date clumn is null then I want display all record but date column is null that time error occured.ho to resolve this??

You can check like this, If(list1 != Null){}. Otherwise what error are you getting? Thanks
