TreeListView error on while we import to XamlFormatProvider

Hi,

We have a WPF RadTreeListView in one of our RichText box we are able to succesfully export this to XAML and save to DB.
But when we import the xaml from DB to show it back as a document we are getting the following error:

'No matching constructor found on type 'Telerik.Windows.Controls.TreeListView.TreeListViewKeyboardCommandProvider'. You can use the Arguments or FactoryMethod directives to construct this type.'

Please help us as this is very critical for our project.

Hyperlink underline disappearing

Hello,

I observe strange bahavior with hyperlink when you press "Backspace" button. More detail.
Open RadRichTextBox sample in "Demos - RadControls for WPF". In opened document place caret in place after last hyperlink letter (for example, after http://www.telerik.com). Press "Backspace" button. Instead delete the last letter, disappears hyperlink underline. If you press "Backspace" button again - last hyperlink letter will be deleted.

Is it possible to realize standard behavior (delete last letter after first "Backspace" button press)?

Style GanttTask Event highlight background

HI,

I would like to know if there is a way to change the color of an event's background when it is highlighted/hovered over and when it is selected, preferably without having to resort to creating a ControlTemplate. Right now, I know how to change every other property of the event within a intrinsic style for EventContainer, and using style triggers i can change these properties depending on the state of the event. However, the Background property doesn't appear to work when using triggers. An example: Here is my EventContainer Style:

<Style TargetType="g:EventContainer">

<Setter Property="Background" Value="Green"/>

<Setter Property="Foreground" Value="White"/>

<Setter Property="BorderThickness" Value="0"/>

<Style.Triggers>

<Trigger Property="IsMouseOver" Value="True">

<Setter Property="Foreground" Value="Red"/>

<Setter Property="BorderThickness" Value="0"/>

</Trigger>

<Trigger Property="IsFocused" Value="True">

<Setter Property="Foreground" Value="Red"/>

<Setter Property="BorderThickness" Value="0"/>

<Setter Property="Background" Value="Blue"/>

</Trigger>

</Style.Triggers>

</Style>

When the event is hovered over, the title text of the event correctly changes from white to red, as defined in the style, but when the event is selected, the background does not change from green to blue. As I stated, I would like to avoid using ControlTemplate if it is possible, as ControlTemplates require a lot of extra useless markup, and a knowledge of the underlying infrastructure, which is impossible to get for the Telerik libraries.

How to keep the size of a floating pane equal to the size of the pane being docked?

I have panes that are docked, and for example have a size of 640 * 480 while docked. When I move the pane outside the application the floating pane now gets a different size, 220 * 300.

I want to keep the size equal, the floating pane should keep the size of the docked pane. I tried setting RadDocking.SetFloatingSize on the splitcontainer, but that does not help.

How can I solve this?

No values displayed (but object data source method called)

I am attempting a simple example. I have a class with appropriate method to return a list of user objects. I've declaratively bound it to the autocompletebox. When I debug it, the select method does get called, but does not display anything?

I used the same code on some other machine, it works.

Does this need 4.5? as one of the box has it (where it works) and other does not.

This style works "somehow" but when I use it on a diagramshape and select the shape at runtime I no longer have the "connectors adorner".

Furthermore (I think this is a more common problem) I'm no longer theme aware.
I set my theme at runtime - "unstyled" controls change their appearance - but styled ones do not.

The primary problem is that I want to change some behaviour and need to style the control - without loosing the connector adorner.

Limit drop to existing Nodes

Hi,

my approach (using MVVM) is something like your "OrgChart" example.

Assume this example, where you start with the CEO predefined.
Then from a list the user can drag employees to the chart.
Employees can change their position (by being dragged to a different "chief / leader").
Every Employee is assigned to another one.
There are kind of employees which may not "rule" others (let's say trainees). These employees can't act as "drop destination"

So the rules are:
- One node is fixed (CEO)
- the user must drop the new / existing Node on an existing one
- depending on the node type dropping is enabled or not (Visual feedback should be provided - like containers do)

After a drop operation I recalculate the Org-Model add / remove connectors and redraw the chart.

Is there an easy way to achieve this?
