ExpressionDark theme unreadable on nested properties

Hi,

there is a bug in implicit expression dark theme for RadPropertyGrid when NestedPropertiesVisibility is set to Visible.

Content template of SelectedField is unreadable, because Foreground and Background are almost the same color (light gray)

Here is simple demonstration:

Just select a field in propertygrid and move mouse cursor out of the field

Restrict Image Type

I'm trying to use the Image Editor (WPF Q3 2012 WPF4.0) for the first time. In the open and save dialog is there a way to restrict the user to just JPG files (*.jpg, *.fpeg) types. I don't see how to do this from the documentation.

Multiple textboxes/textblocks in a cell, chooses right one on edit.

I have a GridViewDataColumn with a CellTemplate that contains an ItemsControl which is templated for TextBlocks. The CellEditTemplate has a similar setup only with TextBoxes. Essentially I have several TextBlocks/TextBoxes per cell. What I want is when the user double clicks on a TextBlock the grid goes into editing mode and selects the corresponding TextBox by index. If I double click the third TextBlock in the cell then I want the third TextBox to start editing.

The default behavior is the grid selects the first TextBox upon entering edit mode. I have tried a couple of code behind solutions based on moving through the visual tree when PreviewMouseDoubleClick happens. But when I force the grid to enter edit mode the TextBoxes are not part of the visual tree as I would expect them to be.

I would prefer a pure XAML solution but do not know how that would be done.

TabControl as region in Prism4 doesn't work as expected for Activate method

If you specify a normal tab control as a region and activate one of the views (already added) then the corresponding tab gets selected.
However if the RadTabControl is used as a region then nothing happens when the view is activated (tab doesn't get selected).
Also all tabs remain active views at all times and IsActive property for ViewModel (that implements IActiveAware) doesn't ever change i.e. on switching tabs.

I could have very well used a normal tab control but I want the expression dark theme which is only available for the RadTabControl.

Need Help on loading and controlling RadPanelBar programatically in MVVM mode

Hi,

I need help in loading and controlling RadPanelBar programatically in MVVM pattern start from loading the panelBarItems.
I want to create a RadPanelBar which will have set of items and each item will have the ContentControl (loads an UserControl). I want to control the expand and selection of each item by set of buttons. Let me explain this briefly,

my RadPanelBar has 3 items, each PanelBarItem loads an usercontrol. I should be able to control expand of these panelbar items by a listbox having 3 buttons i.e. 1st RadPanelBar item expands on 1st button click, 2nd item expands on 2nd button click etc.
I should be able to do everything progrmatically i.e. even loading the panelbar items and List box items.

I am attaching the XAML code i have used to achieve this,

<telerik:RadPanelBar x:Name="mybar" Width="830" Height="430" HorizontalAlignment="Left" Grid.Row="0" Focusable="False"

VerticalAlignment="Stretch" BorderBrush="#FFCBD8E8" BorderThickness="1 1 0 1" ExpandMode="Multiple" Margin="10,10,10,10" Background="Transparent"

ItemsSource="{Binding PanelBarItemsList}"

SelectedItem="{Binding PanelBarSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">

<telerik:RadPanelBar.ItemTemplate>

<DataTemplate>

<telerik:RadPanelBarItem x:Name="pnliTopic" IsSelected="{Binding IsSelectedValue, Mode=TwoWay}" IsExpanded="{Binding IsExpandedValue, Mode=TwoWay}" >

<telerik:RadPanelBarItem.Header>

<TextBlock Text="{Binding Name}" />

</telerik:RadPanelBarItem.Header>

<ContentControl x:Name="View" Margin="10,10,10,10" Visibility="Visible" HorizontalAlignment="Left" VerticalAlignment="Top" Width="Auto" Height="Auto"

Content="{Binding UserControlView}" />

</telerik:RadPanelBarItem>

</DataTemplate>

</telerik:RadPanelBar.ItemTemplate>

</telerik:RadPanelBar>

Here is the view model code,

private ObservableCollection<ToolOption> m_PanelBarItems;

public ObservableCollection<ToolOption> SettingsList

{

get { return m_PanelBarItems; }

set

{

m_PanelBarItems = value;

}

Contructor()

{

m_PanelBarItems = new ObservableCollection<PanelBarItem>();

foreach (string strTool in m_LocalCollection)

{

PanelBarItem item= new ToolOption(strTool );

m_PanelBarItems.Add(item);

}

 m_PanelBarItems[0].IsExpandedvalue = true;

 m_PanelBarItems[0].IsSelectedValue = true;

 m_PanelBarItems[0].UserControlView = new UserControlView1();

 PanelBarSelected = m_PanelBarItems[0];

 m_PanelBarItems[0].UserControlView.Visibility = Visibility.Visible;

 this.OnPropertyChanged("PanelBarSelectTool");

}

public object PanelBarSelectTool { get; set; }

//PanelBarItem Class definition

public class PanelBarItem: INotifyPropertyChanged

{

public string Name { get; set; }

private bool selected;

private bool expanded;

public System.Windows.Controls.ContentControl m_View = null;

//private object m_View = null;

public bool IsSelectedValue

{

get

{

return selected;

}

set

{

selected = value;

this.OnPropertyChanged("IsSelectedValue");

}

public bool IsExpandedvalue

{

get

{

return expanded;

}

set

{

expanded = value;

this.OnPropertyChanged("IsExpandedvalue");

}

public System.Windows.Controls.ContentControl UserControlView

{

get

{

return m_View;

}

set

{

if (m_View != value)

{

m_View = value;

}

public PanelBarItem(string name)

{

this.Name = name;

this.IsSelectedValue = false;

this.IsExpandedvalue = false;

}

public event PropertyChangedEventHandler PropertyChanged;

private void OnPropertyChanged(string propertyName)

{

if (this.PropertyChanged != null)

{

this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

}

I hope you understand what i want to achieve.
Let me know if you need more information.

Visual Studio 2012 Designer Error With Implicit Themes

I am encountering a problem when applying implicit themes to a vb.net WPF project. The problem appears to be with the
RibbonView implicit theme: Themes/OfficeBlack/Telerik.Windows.Controls.RibbonView.xaml

I followed the instructions from the help system for implicit themes and created a resource dictionary in the application.xaml file as follows:

<ResourceDictionary.MergedDictionaries>

</ResourceDictionary.MergedDictionaries>

I also referenced the corresponding dlls from the installation directory:
C:\Program Files (x86)\Telerik\RadControls for WPF Q3 2012\Themes.Implicit\WPF40\Metro\Themes

The program compiles and runs OK.
The problem is that the xaml designer has the following error

System.ArgumentException

'{DependencyProperty.UnsetValue}' is not a valid value for the 'Telerik.Windows.Controls.RadRibbonGallery.Icon' property on a Setter.

The stack Trace indicates that the error takes place in the expression designer. This error is listed 3 times.
There are no errors in the xaml code or in the vb.net code
That same error occurs for several of the themes that I have tried (Windows8, windows7, OfficeBlue, OfficeBlack)

The markup for window that I am designing does not use the radRibbonView, nor does it use the RadRibbonGallery.

When I remove the following line from the application Xaml ResourceDictionary merge:
<ResourceDictionary Source="Themes/OfficeBlack/Telerik.Windows.Controls.RibbonView.xaml">

the errors disappear.

Do you have a bug in the RibbonView.xaml?

Thanks for your help in solving this

Thanks

Philippe
