Suggestion about behavior

Hello again,

I want to suggest a better behavior for this control that would help it stay 508 compliant. When I use the RadTabControl in my applications, and a user attempts to change the tab using just the keyboard, this control behaves in a way that is not typical. For starters, the RadTabItem’s default IsTabStop value is “false”. Second, even when we set the IsTabStop to “true”, the focus is automatically changed from the Tabs to the first control in the tab being activated. This is not a typical behavior as seen in the stock TabControl that Microsoft wrote (or any other Tab control to speak of). Finally there is the matter of the AutomationPeer (as in there is none for either the RadTabControl or RadTabItem). This presents an issue for customers like me who are required to make our products accessible.

AutomationPeer for RadTabControl and RadTabItem

Hello All,

Is Telerik planning on completing the AutomationPeer implementations of these two controls? The current implementation returns null for both control's OnCreateAutomationPeer() methods.

Set DateTimeWatermarkContent from Style

Hi

I wanted to set the default DateTimeWatermarkContent for RadDatePicker from Style. At first it seemed not working (the default "Enter date" text appeared), later I have defined the property for each RadDatePicker manually and later removed these manual overrides for some reason. Surprisingly, the Style definition seemed to work now, but only in Visual Studio (I could even change the default value and the designer followed the changes). However, when I have run the application, my style definition was not used ("Enter date", again). Even stranger that from this point on, the designer "forgot" to use the style again as well.

What am I doing wrong? It is possible to set this property from Style?

My code:

<Window.Resources>

</Style>

</ResourceDictionary>

</Window.Resources>
...
<telerik:RadDatePicker Grid.Column="1" Grid.Row="0"></telerik:RadDatePicker>
<telerik:RadDatePicker Grid.Column="1" Grid.Row="2"></telerik:RadDatePicker>

...

Any ideas?

Thanks for the help in advance!

Modal Dialog is not truely Modal

Hello,

I wanted to make a suggestion for your next release of RadWindow. When it is active in a modal state (i.e. prompt or ShowDialog), it does not behave as one would expect. The Tab, Control, and Directional navigation does not operate in a manner that the customer would expect. If you go to your online demo, activate one of the Prompt samples. Than place focus in the address bar and start tabbing. You will notice that the controls behind the prompt get keyboard focus as well as Control and Navigation focus.

It would be great if your prompt was the only thing a user can focus to. I don't have to tell you how much of a problem this is in the case of protected (meaning that if I wanted a user to do something before gaining access to the main application a user can bybass my prompt and interact with the protected controls).

Multibinding in RadTreeView

Hi, i've got a problem.
in my project i've a class like this :

public class Progetto

{

public Progetto()

{

ID = 0;

Descrizione = String.Empty;

Stringhe = new ObservableCollection<Stringa>();

Sprites = new ObservableCollection<Sprite>();

}

public int ID { set; get; }

public String Descrizione { set; get; }

public ObservableCollection<Stringa> Stringhe { set; get; }

public ObservableCollection<Sprite> Sprites { set; get; }

}

In my RadTree i'd like to see under the root node (Progetto) the two items "stringhe" and "sprites". I Tried with HierarchicalDataTemplate but with no result because under the root node i can only see "Stringhe" or "Sprites"... how to see that together ?? :

here my Hierrarchical..

<HierarchicalDataTemplate x:Key="Stringa">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding Ciao}" Foreground="Black" FontWeight="Bold" FontSize="12" />

<TextBlock Text="{Binding Descrizione}" Foreground="Black" FontWeight="Bold" FontSize="12" />

</StackPanel>

</HierarchicalDataTemplate>

<HierarchicalDataTemplate x:Key="Sprite">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding ID}" Foreground="Black" FontWeight="Bold" FontSize="12" />

<TextBlock Text="{Binding Descrizione}" Foreground="Black" FontWeight="Bold" FontSize="12" />

</StackPanel>

</HierarchicalDataTemplate>

<HierarchicalDataTemplate x:Key="Progetti" ItemsSource="{Binding Stringhe}"

ItemTemplate="{StaticResource Stringa}">

<StackPanel Orientation="Horizontal" >

<TextBlock Text="{Binding ID}" Foreground="Black" FontWeight="Bold" FontSize="12" />

<TextBlock Text="{Binding Descrizione}" Foreground="Black" FontWeight="Bold" FontSize="12" />

</StackPanel>

</HierarchicalDataTemplate>

Any Idea.. THANX IN ADVANCE
