thanks for your help

In your VB project click Add New Item (from the File menu) and select User Control.

Add the controls you want (e.g. the text box and the button) to this new user control and write the code behind the button:

VB Code:

raiseevent blah

You'll have to declare the event in the user control as follows:

VB Code:

Public Event blah()

Close and save the user control and then build your solution.

Look in the toolbox and you should find your new user control. Drop it on a form and you should be able to find the following event in the form.

VB Code:

Private Sub UserControl11_blah() Handles UserControl11.blah
 
End Sub

ok... that work's but it doesn't look like what i expected

Maybe there is a way to use a combobox instead of a textbox + button and the click-event which opens the dropdown-list could be used.

I experimented with this idea but it doesn't work because the OnDrawItem is fired more than one time if i click on the dropdown-button.

Code:

---

Imports System.ComponentModel
Imports System.Drawing

Public Class MultiComboBox
    Inherits ComboBox

    Protected Overrides Sub OnDrawItem(ByVal ea As DrawItemEventArgs)

        ' do what i want to do

    end sub

---

I'm sure that also the small arrow can be changed to (...) but i've no idea how to do this.

Maybe you could try using a flat style textbox with a standard button and putting them both on top of a 3D style Panel control.

I too have had problems making my user controls look as good as the supplied ones.

I have come to the conclusion that it is best to redesign your UI to work with standard controls - that is what your users will be used to in any case.
