Hi,

I have error message :Object cannot be cast from DBNull to other types. when i try to assign null value to poDate data field. My database is mySql.

  protected void DetailsView1_ItemUpdating(object sender, DetailsViewUpdateEventArgs e)
  {
        if (e.NewValues["poDate"] == null)
           e.NewValues["poDate"] = DBNull.Value ;

How to solve this problem?

TIA.
