Hi,

I'm using RadSlider in range mode and doing TwoWay databinding on SelectionStart and StelectionEnd properties. I set the values within Minimum/Maximum range. However, the very first time during dialog load the Slider coerces SelectionStart value to 0.

This is the slider code:

<RadSlider Minimum="-10" Maximum="50"

SelectionStart="{Binding Path=CappedMinBitrate, Mode=TwoWay}"

SelectionEnd="{Binding Path=CappedMaxBitrate, Mode=TwoWay}"

IsSelectionRangeEnabled="True"

/>

Initial valud of SelectionStart is set to 3.0. In the attached screenshot you can see how the value is being set to 0 from CoerceSelectionStart method.

Please let me know if I'm doing something wrong or there is a way to fix it.

Thank you,
Ruben

Ticks & Thumb questions

Hello,
First, thanks for making such a great library! I saved many hours by using the WPF controls.
I am working with the Slider with Selection Range enabled at the moment.
My slider should start at -12 and end at 0. This range can change, but will remain from a negative value to 0.
I would like the tick marks to be set every 4 units for instance, but I want the slider to increase or decrease by one only. Do you have any tip on how to achieve such behavior?
I would like also to lock the position of a thumb in a range slider, is that possible?
Thanks in advance for your support.

Many-To-Many hierarchy

TreeView does a good job of representing a One-To-Many hierarchy. However, I need the ability to represent a Many-To-Many hierarchy. What I picture is more of a hierarchical spider diagram. So, I can select a node, it moves into focus and it shows all of the parents (many) and children (many) as legs. Does anyone have a suggested control that does this?

I thought of using 2 TreeViews. So, I'd change the parent TreeView to flow from Right to Left with the selected node in the middle with a Right side orientation. Then, the children would be represented with the traditional TreeView flowing from Left to Right with the selected node in the middle.

This idea would work, but I prefer to have one control that does it all.

Thanks for your ideas,
Joel.

Question about Frame controls

Hello, here's the scenario.

I have a Telerik Window and I have divided it's content to two parts. Left frame and Right frame using Frame Controls. I navigated to the left frame (LeftPage.xaml) by NavigationServices, same as the right frame (RightPage.xaml). Is there a possible way to get the current data that is loaded from the LeftPage.xaml to the RightPage.xaml?

For example: In my behind the code in LeftPage.xaml, I have a code that says textBox1.text = textBox2.text; so normally when I type in the left page on the textbox2 it will automatically get the current data that is being inputted to textbox1. Now my question is it possible to get the current data in textbox2 to the RightPage textbox3?

I tried binding it but it did not work, I tried instantiating the RightPage and access the textbox3 but it still wont work. It basically does not even let me do a evenet on another page from the original page. Am I doing something wrong?

The use of ContentPropertyAttribute in TransitionControl

The thing is, i want to be able to add custom user controls to the TransitionControl. Something like...

<local:CardControl>

<Button Content="Hello" />

</local:CardControl>

...and to be able to implement custom transition logic inside the inherited class.

Now, the class CardControl inherits from RadTransitionControl, like shown below:

[ContentProperty("Items")]

[ContentWrapper(typeof(Collection<UIElement>))]

public class CardControl : RadTransitionControl

{

public static readonly DependencyProperty ItemsProperty =

DependencyProperty.Register("Items", typeof(Collection<UIElement>),



                 typeof

(CardControl), new FrameworkPropertyMetadata(new

Collection<UIElement>(),

FrameworkPropertyMetadataOptions.AffectsRender

, OnItemsChanged));

public Collection<UIElement> Items

{

get { return (Collection<UIElement>)GetValue(ItemsProperty); }

set

{

SetValue(ItemsProperty, value);

}

public CardControl()

{

}

private static void OnItemsChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs eventArgs)

{

(dependencyObject as CardControl).Content = (eventArgs.NewValue as Collection<UIElement>)[0];

}

As you can see, I've added the ContentPropertyAttribute, which in turn, should allow the user to add items in XAML, and store them in the Items property. It works, if i use a single item, but it shows no reaction, when i try to use the collection of UIElements.

Any ideas on how to make it work?
Thanks,

TransitionControl

Exception when changing DataContext
