Changing Implicit Styles RadRibbonView Backstage

I am trying to change the application theme at runtime using the approach provided on the Rad Controls for WPF website.

I'm clearing the default MergedDictionaries instantiated in App.xaml and updating with new MergedDictionaries from the NoXaml binaries that I have referenced in the project. The button to execute this code is located on the Backstage via DelegateCommand. When the code is executed, it appears to affect the rest of the application but not the Backstage itself. If I navigate to a different ribbon tab and back to the Backstage, then much of the styling is updated, but with the loss of the hover effects and some of the styling of the strips on the left hand side.
I have references to Telerik.Windows.Controls.xaml, Telerik.Windows.Controls.Input.xaml, Telerik.Windows.Controls.Navigation.xaml, and Telerik.Windows.Controls.RibbonView.xaml being updated when the code runs.

Is there something that I should be doing differently? Thanks for your help!

RibbonWindow/RibbonView - Title Style and Icon

1st issue - We're new to the Telerik controls. When using the RibbonWindow and the RibbonView, the Title of the Window is black without a white blur behind/around it, making the title very difficult to see. Which style do I need to change to add the BlurEffect? Also, on Windows 7 with Aero turned on, could not this blur not be the default style.

2nd issue - The interaction between the RibbonWindow and RibbonView, the title, and the IconVisibility/WindowIconVisibility properties is quite confusing. In our sample applications, the window icon shows up perfectly to the left of the QAT. But we cannot get the icon to display in our Win32 application with integrated Telerik controls nor does the window menu open when clicking on it. The RibbonWindow/RibbonView and QAT display correctly. I seem to have tried all combinations of IconVisibility/WindowIconVisibility property settings. I don't know what else to try. Any guidance would be appreciated.

Maximum Typing Delay for AutoComplete

Some of my users are slow typists. Is there a way to adjust the maximum delay between key strokes before the combobox assumes you are starting a new word?

In other words, if the following items are bound to the combo box:

12345
12346
12347
4111

And the user starts typing 1234, if they pause long enough between the 3 and the 4, the selection will go to the 4111 item. I want to be able to edit the amount of time they are allowed to take between key strokes before it it assumes they're starting a new search.
Thanks.

The header of GridViewColumnGroup doesn't gets refreshed when set programatically.

Hi Telerik Team,

I have added a GridViewColumnGroup to a WPF RadGridView (version 2011.3.1220.40).

<Telerik:RadGridView.ColumnGroups>

<Telerik:GridViewColumnGroup Name="gvGroup" Header="Header"></Telerik:GridViewColumnGroup>

</Telerik:RadGridView.ColumnGroups>

The header text is dynamic in my case. The gridview data gets refreshed on click of an hyperlinkcolumn of the same grid, so the header text of the GridViewColumnGroup also needs to refreshed. I tried changing the header text programmatically as given below.

The data in the gridview gets refreshed but the header text of the GridViewColumnGroup is not getting refreshed consistently.
Sometimes it does gets refreshed where as sometimes it doesn't .

foreach (GridViewColumnGroup item in radgvPrerequisiteRelType.ColumnGroups)

{

if (item.Name == "gvGroup")

{

item.Header = null;

item.Header = "ProjectId [" + lngProjectId + "]";

}

Could you please let me know the solution for this problem.

Thanks,
Regards,
Mausami

Collection.Add(new TileView() { Content = "Item14", RestoredHeight = 100, RestoredWidth = 122 });

Collection.Add(new TileView() { Content = "Item15", RestoredHeight = 100, RestoredWidth = 245 });

Collection.Add(new TileView() { Content = "Item16", RestoredHeight = 100, RestoredWidth = 245 });

Self-Referencing Binding

Hi,

I have got model:

public class Category

{

public int Id { get; set; }

public string Name { get; set; }

public int? ParentCategoryId { get; set; }

public virtual Category ParentCategory { get; set; }

public virtual ICollection<Category> SubCategories { get; set; }

}

And in MVVM:

private ObservableCollection<Category> _categories;

public ObservableCollection<Category> Categories

{

get { return _categories; }

set

{

if (_categories == value) return;

_categories = value;

OnPropertyChanged("Categories");

}

I found an example, but I don't want to create a new model, and even more so to edit an existing one.
Could you explain to me step-by-step, how I can bind the data to treeview (with parents and their childs')?
