[DotNetDevelopment] Re: Populating data in textbox based on another field

Okay, so I was able to successfully write an event handler on
OnTextChanged to disable textbox3 if textbox2 is not blank but I'm not
sure which "command" I need to connect to my data source and then
populate it the information into textbox3. So far I have this in my
event handler:

Protected Sub DD_jobno_TextChanged(ByVal sender As Object, ByVal e As
System.EventArgs) Handles DD_jobno.TextChanged
If DD_jobno.DataValueField = " " Then
GLAcct.Enabled = True

Else
GLAcct.BackColor = Drawing.Color.Gray
GLAcct.Enabled = False

End If

End Sub
