Not sure if I added the code right but I still have the same problem
when I go back and select the blank line in the jobno dropdown list
the GLAcct textbox still stays disabled.
Here is my code.
Protected Sub DD_jobno_TextChanged(ByVal sender As Object, ByVal e As
System.EventArgs) Handles DD_jobno.TextChanged
If DD_jobno.DataValueField.Trim.Length = 1 Then
GLAcct.Enabled = True
Else
GLAcct.BackColor = Drawing.Color.Gray
GLAcct.Enabled = False
End If
End Sub
