Combo Box contents into a text box field

[coyney22]

Hi all

I have 3 combo boxes that users select data, i want to pass the selected data to a text box, as this text box then encodes to a bar code,

I can manually type in the text box and the bar code works, I just need to pass the data from the combo boxes to the text boxes.

Is this the correct way to do it or am i way of the mark.

Thanks in advance

Do you want this value 'passed' only when there is a selection made in all 3 boxs?

There are many ways you could get there. This example assumes DropStyle of DropDown where the user can type a value, but will handle the selected dropdown text change also

    Private Sub ComboBox1_SelectedValueChanged(sender As Object, e As EventArgs) Handles ComboBox1.TextChanged,
                                                                                         ComboBox2.TextChanged,
                                                                                         ComboBox3.TextChanged
        If Not String.IsNullOrEmpty(ComboBox1.Text) AndAlso
           Not String.IsNullOrEmpty(ComboBox2.Text) AndAlso
           Not String.IsNullOrEmpty(ComboBox3.Text) Then
            TextBox1.Text = ComboBox1.Text & ComboBox2.Text & ComboBox3.Text
        Else
            TextBox1.Clear()
        End If
    End Sub

you could modify this into a button click easy enough
