how to restrict duplication of items in RadListBox in WinForms Q3 2009 SP1

Hi,
i use the RadListBox that comes with WinForms Q3 2009 SP1 in my C# project. One major difficulty i face now is i want to perform a condition on adding items to the radListBox. i.e, all items must be added only once.no duplication of same item must be present. In the standard listbox of Windows Forms i used if(!listbox1.item.contains(s)) to enter a string s, but i need to know how to implement this using RadListBox.

No tabbed child views

Hello,

How do I disable tabbed child views that belongs to the same parent but have different columns. I want to be able to expand many childs to see data from them at same time - not tab between them.

Example: Parent has two childs that are from different dataset and have different columns and data in them. Is there a way of not getting them tabbed when setting up their relations to the parent.

Regards

TextChanged event with SpinEditor and DateTimePicker doesn't work

Hello

I need to enable the update button in a form whenever the value of any control in the form change its value. It works fine for RadTextBox, RadComboBox, but it doesn't work either for RadSpinEditor nor RadDateTimePicker.

                     Private Sub Text_Changed(ByVal sender As System.Object, ByVal e As System.EventArgs) _         
                        Handles RadTextBox1.TextChanged, _         
                                RadComboBox1.TextChanged, _         
                                RadDateTimePicker1.TextChanged, _         
                                RadSpinEditor1.TextChanged         
                     
                    If RadTextBox1.ContainsFocus Or _         
                       RadComboBox1.ContainsFocus Or _         
                       RadDateTimePicker1.ContainsFocus Or _         
                       RadSpinEditor1.ContainsFocus Then         
                         Me.UpdateButton.Enabled = True         
                    End If         
                     
                            
                End Sub         

I tried a more generic way to do it with this procedure, that didn't work too:

                             
            Private Sub Text_Changed(ByVal sender As System.Object, ByVal e As System.EventArgs) _         
                        Handles RadTextBox1.TextChanged, _         
                                RadComboBox1.TextChanged, _         
                                RadDateTimePicker1.TextChanged, _         
                                RadSpinEditor1.TextChanged         
                     
                           
                    If HasFocus(sender) Then         
                        Me.RadButton1.Enabled = True         
                    End If         
                     
            End Sub         
                     
                     
            Public Function HasFocus(ByVal sender As System.Object) As Boolean         
                    Dim radElemento As Telerik.WinControls.RadElement         
                     
                    If sender.GetType Is GetType(Telerik.WinControls.UI.RadTextBox) Then         
                        radElemento = DirectCast(sender, Telerik.WinControls.UI.RadTextBox).FocusedElement         
                    End If         
                    If sender.GetType Is GetType(Telerik.WinControls.UI.RadComboBox) Then         
                        radElemento = DirectCast(sender, Telerik.WinControls.UI.RadComboBox).FocusedElement         
                    End If         
                    If sender.GetType Is GetType(Telerik.WinControls.UI.RadSpinEditor) Then         
                        radElemento = DirectCast(sender, Telerik.WinControls.UI.RadSpinEditor).FocusedElement         
                    End If         
                    If sender.GetType Is GetType(Telerik.WinControls.UI.RadDateTimePicker) Then         
                        radElemento = DirectCast(sender, Telerik.WinControls.UI.RadDateTimePicker).FocusedElement         
                    End If         
                    If sender.GetType Is GetType(Telerik.WinControls.UI.RadCheckBox) Then         
                        radElemento = DirectCast(sender, Telerik.WinControls.UI.RadCheckBox).FocusedElement         
                    End If         
                     
                    If Not radElemento Is Nothing AndAlso radElemento.ContainsFocus Then         
                        Return True         
                    Else         
                        Return False         
                    End If         
            End Function         

Thank you

Collapsible Pane Issues

I am using the CollapsiblePane example to learn more about this control. I am having problems setting the text property of the control. If I use the Theme Manager, I can set the property but, I cannot set it in the properties or in code. The component always seems to default to "CollapsiblePane". Is there something I am overlooking in setting the text property for the object?

Thanks

Show a normal arrow cursor over the splitter when the splitter is fixed?

Is it possible to do this? I want to selectively turn on and off the resize ability using the 'Fixed' property on the SplitterElement. It would be nice to not still show the resize arrows when resizing will not work.'

Thanks!
