Category([COLOR=maroon]"Action"[/COLOR])> _
[COLOR=blue]Public[/COLOR] [COLOR=blue]Event[/COLOR] ButtonTwoClick [COLOR=blue]As[/COLOR] EventHandler
 
[COLOR=blue]Protected[/COLOR] [COLOR=blue]Overridable[/COLOR] [COLOR=blue]Sub[/COLOR] OnButtonTwoClick([COLOR=blue]ByVal[/COLOR] sender [COLOR=blue]As[/COLOR] [COLOR=blue]Object[/COLOR], [COLOR=blue]ByVal[/COLOR] e [COLOR=blue]As[/COLOR] EventArgs) _

I think it would be better to just use the property of the UserControl as a pass-through for the ComboBox property ...

Just curious: did you actually try this?
It was my first approach too. But it does not seem to work as expected in design time.

Can't say that I did. There;d have to be a way to make it work, wouldn't there? I'm too lazy to try though.

I think I more or less worked it out.
Only, the thing is: it's just Strings() all over again. Although consistent with the behaviour of ComboBox.Items and other ListControl.Items in design time.

This seems to do the trick (both the EditorAttribute and the DesignerSerializationVisibilityAttribute are needed):

[SIZE=2]<Description([/SIZE][SIZE=2][COLOR=#800000]"The items of the Combobox in this User Control"[/COLOR][/SIZE][SIZE=2]), _
Editor([/SIZE][SIZE=2][COLOR=#800000]"System.Windows.Forms.Design.ListControlStringCollectionEditor, System.Design"[/COLOR][/SIZE][SIZE=2], _
[/SIZE][SIZE=2][COLOR=#0000ff]GetType[/COLOR][/SIZE][SIZE=2](UITypeEditor)), _
DesignerSerializationVisibility(DesignerSerializationVisibility.Content), _
Category([/SIZE][SIZE=2][COLOR=#800000]"Data"[/COLOR][/SIZE][SIZE=2])> _
[/SIZE][SIZE=2][COLOR=#0000ff]Public [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]ReadOnly [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Property[/COLOR][/SIZE][SIZE=2] Items() [/SIZE][SIZE=2][COLOR=#0000ff]As[/COLOR][/SIZE][SIZE=2] ComboBox.ObjectCollection
[/SIZE][SIZE=2][COLOR=#0000ff]Get
[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]    Return[/COLOR][/SIZE][SIZE=2] ComboBoxItems.Items
[/SIZE][SIZE=2][COLOR=#0000ff]End [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Get
[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]End [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Property
[/COLOR][/SIZE]

Thanks everyone, my problem it's OK.

This code: Don't work.
Public ReadOnly Property items() As ComboBox.ObjectCollection
Get
Return Me.ComboBox1.Items
End Get
End Property

This code: so work.
Public Property Items() As String()
Get
Dim result(ComboBoxItems.Items.Count - 1) As String
ComboBoxItems.Items.CopyTo(result, 0)
Return result
End Get
Set(ByVal value As String())
ComboBoxItems.Items.Clear()
ComboBoxItems.Items.AddRange(value)
End Set
End Property

This code: Don't work.

It does, see my previous post. You have to tell the IDE it has to use the ListControlStringCollectionEditor to edit the Items. I believe it is the better solution.

You can expose the DataSource and DisplayItem properties of the internal ComboBox from your usercontrol (and eventually place them in their own category on the toolbox).

How to update dataset to table? I used that code in dataset it's ok, but in database can't update why?

Try
Me.Validate()
Me.CustomerBindingSource.EndEdit()
Me.CustomerTableAdapter.Update(Me.XtremeDataSet.Customer)
MsgBox("Update successful")
Catch ex As Exception
MsgBox("Update failed")
EndTry

 

[Don Delegate]

Show the text of the exception. Then you'll probably know why.
Also: how is this related to this thread?

[COLOR=black][FONT=Courier New][COLOR=blue]Try[/COLOR]
    Validate()
    CustomerBindingSource.EndEdit()
    CustomerTableAdapter.Update(XtremeDataSet.Customer)
[COLOR=blue]Catch[/COLOR] ex [COLOR=blue]As[/COLOR] Exception
    MessageBox.Show(ex.ToString)
[COLOR=blue]End[/COLOR] [COLOR=blue]Try[/COLOR]
[/FONT][/COLOR]
