null error[RESOLVED]

I'm getting this error when I try to populate my page. The field can be null in the database, so how do I get around this?

Cast from type 'DBNull' to type 'String' is not valid.

Try this:

Code:

---

if(dr["Author"] == DBNull.Value) {
    txtAuthor.Name = String.Empty;
}
else {
    txtAuthor.Name = dr["Author"];
}

---

Also, isDBNull(avalue)

thanks guys...

I used

Code:

---

If objDataReader("display_start_date") Is DBNull.Value Then
                        txtIntDisStartDate.Text = String.Empty
                    Else
                        txtIntDisStartDate.Text = ("display_start_date")
                    End If
