Updating null value fields in DetailsView

[ngk]

Hi

I have master/detail web forms and form1 has a GridView and form2 has a DetailsView. I have some filelds on the DetailView with null values in some records and when I try to update those records by entering some data, DetailsView is not updating the backend database. I am not getting any eorror message either. If any record with all fields populated with some values when initially displayed in DetailsView gets updated fine.

I am using SQLServer datasource and the table accepts Null values in the fields that are giving problem.

I am hoping someone would help me out with this problem.

Thanks in advance.
