dropdownlists

hi
i have fourm with a drop down box which has 4 things in it. e.g property, unlisted, listed

and i have another drop down called country with a list of countries.

what im trying to do it when someone click on the unlisted from the first drop down and tries pressing ok i want a pop up to say have to fill in country.

anyone any ideas on how to do this

Just put in the selectedindex change event of the first combo box, something like:

VB.NET Code:

If cb2.SelectedIndex = -1 Then
            MsgBox("You must select a country.", MsgBoxStyle.Information)
            Exit Sub
        End If

sorry i dont get what u mean by Just put in the selectedindex change event of the first combo box.

how does the code no that i picked unlisted and not one of the other ones in the list

Just select the SelectIndexChanged event of the first combo box...

VB.NET Code:

Private Sub cb1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cb1.SelectedIndexChanged
      If cb2.SelectedIndex = -1 Then
                  MsgBox("You must select a country.", MsgBoxStyle.Information)
                  Exit Sub
              End If 
    End Sub

I'm assuming that your combos are called cb1 and cb2, so you probably need to change the names...

ok great will try that thanks for the help

everytime i open the forum the message box pops up

You need to change test value... Don't use -1 becuase -1 indicates nothing is selected by the user. Change -1 to whatever index that "Unlisted" is on in your list. Remember, index in a collection is zero based, so if Unlisted is the 2nd item in the list, its index is 1.
