[RESOLVED] Check text entered in combobox against the dropdownlist genereated

[jadi]

Hi,

I have an windows mobile application. In the windows form of it, I have a combo box.
I load the values in the combobox on frm_load event.
Now we all know what the combo box has the facility that it allows to enter text as well as chose from the dropdown.
So when they enter the text, I want to validate it against the list that is in it.
If not then msbox error.

Can you guide me with,how to validate.

My loading of the combo box is here.

Private Sub mainfrm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim con As New SqlConnection("XXXX")
        Try
            con.Open()
        Catch ex As Exception
             'MsgBox("Problem in Connection with the SQL server")
    
        End Try
        Try
            
            ' filling the combobox with distinct bin numbers
            Dim cmd1 As New SqlCommand(" Select distinct Binnumber from [dbo].[bintable]", con)
            Dim rd1 As SqlDataReader = cmd1.ExecuteReader()
            While rd1.Read()
                Barcode2.Items.Add(rd1(0).ToString)
            End While
        Catch ex As Exception
            MsgBox("Error loading the combo box with bin numbers.")
            con.Close()
        End Try
        Barcode1.Focus()
    End Sub

Can you not just set the style to DropDownList so that they HAVE to select one from the list?

I wish I could. If that was the case iwould have put a listbox or dropdown box, and not a combo box.
Sorry Chris, its a requirement.

OK it was just a suggestion in case you were not aware of that property.

As for validating the text against the items within the combobox, as it seems that you are just adding strings to the combobox you should just be able to do this:

If MyComboBox.Items.Contains(MyComboBox.Text) Then
   'Valid input entered
Else
   'The text isnt in the list
End If
