  How can I create a combobox with pre-defined static items to be able to use in different xaml? Thanks

  WPF (not using MVVM) I have a list of Items ex. 1,2,3,4,5,6 . I was added this list to combobox from code behind. I have grid with rows(AllUsers and SomeUsers related data), When I click on AllUsers data row then in selection changed i was adding 1,2,3,4,5,6 through item source from code behind. when I click on SomeUsers data row then in selection changed i was adding 2,5,6 through itemsource from code behind. Here I was using observable collection for grid data and combobox(it is sub list of observable collection). Combobox is in outside the grid. What ever data is selected in combobox it will automatically updated to my grid model(i was using two way binding in combobox). Problem :- when selection changed happens I was adding relevant data to combobox through Item source from code behind , at that time previously selected value is getting null in the model property(especailly 'AllUsers' data when property contains 1 or 3 or 4 values because those are not exist in combobox list of SomeUsers data

  Is possible to add and delete items with images dinamically?

    Yes anything is possible. Each element in XAML or WPF is represented independently and can be removed.

  Is it possible to scroll through the values of combo box without having to use scroll bar, can i simply scroll the values using touch. or is there an alternate component for doing such things

    You can enable scrollbars but its not possible without implementing it :)

    This is very interesting. I would like to discuss this and figure out the psychology behind it. Are you local in New Delhi area? I am coming to INDIA on 22nd and will be at C# Corner Delhi Chapter event on 28th. If you come there, remind me. I want to spend some time discussing this. We can kill the fear, we can build soldiers.

  Well, if somebody needs here is the code that worked for me:<code> ////ItemTemplate Style estilo = new Style(); estilo.TargetType = typeof(ComboBoxItem); estilo.Setters.Add(new Setter(ComboBoxItem.ForegroundProperty, item.Foreground.SelectedBrush)); comboBoxFactory.SetValue(ComboBox.ItemContainerStyleProperty, estilo); comboBoxFactory.SetValue(ComboBox.ForegroundProperty, item.Foreground.SelectedBrush); </code>

  Hey man, very good tutorial!! Let me make a question... how do I color the Items in the combobox direct in the code? I tried this: <code> var dtFact = new FrameworkElementFactory(typeof(TextBlock)); dtFact.SetBinding(TextBlock.TextProperty, new Binding(String.Format("[{0}]", item.GetHashCode()))); comboBoxFactory.SetValue(ComboBox.ItemTemplateProperty, new DataTemplate { VisualTree = dtFact }); </code> but it Didn't work.. t.i.a.

  Gangadhar, I would say, just go to WPF section of this site and read my articles one by one. I have written ton of articles on WPF and they are very easy to follow. Good luck!

  "Text property of ComboBox represents the text of the current selected item in a ComboBox" Text is the contents of the TextBox part and is not necessarily in the ComboBox item list. It may therefore differ from the selected item

    Thanks for noticing Paul. Appreciate it. I will fix it. This is what happens when you use previous written articles as template.

  Ilya Tsilikov16y agoPosted Sep 23, 2010, 9:32 AM

  I want to note that the proposed definition of ComboBox items is no good at all. Such items don't display properly. You can check it.

    Mahesh Chand16y agoPosted Nov 7, 2010, 5:20 PM

    That is possible Ilya. You get the idea and improve from there. Please share here if you come up with better solutions. Thank you!
