RadDataForm not visible with NoXaml and Implicit Styles

Hi,

It's the first time I'm using Implicit Styles and NoXaml so I'm sure I'm doing something wrong and I hope someone can help me.

I have a Prism project. At main WPF application project, I have added references for all dll I need in all modules. Currently, I've added the following ones:
Telerik.Windows.Controls;
Telerik.Windows.Controls.Charts;
Telerik.Windows.Controls.Data;
Telerik.Windows.Controls.Input;
Telerik.Windows.Controls.Navigation;
Telerik.Windows.Controls.ScheduleView;
Telerik.Windows.Data;

At this project, at App.xaml I've merged the following xaml files (the xaml files Telerik WPF extensions added at Themes folder

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.xaml" />

<ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Input.xaml" />

<ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Navigation.xaml" />

<ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Chart.xaml" />

<ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Data.xaml" />

<ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.ScheduleView.xaml" />

</ResourceDictionary.MergedDictionaries>

Now, I have one module (in a separated project) that has references to:
Telerik.Windows.Controls;
Telerik.Windows.Controls.Data;
Telerik.Windows.Controls.Input;
Telerik.Windows.Controls.Navigation;
Telerik.Windows.Data;

One of the Views in this module contains a RadDataform but it's DataFields are not visible when View appears at UI. I've tried to use DataFormDataField control alone with no success. Am I missing something?

Thanks.

Styling of RadAutoCompleteBoxItems

I'v setup applied a custom style to a RadAutoCompleteBox in order to change its visual design. I would also like to customize its RadAutoCompleteBoxItems (e.g. change the RemoveButton). How can this be achieved?

I found a RadAutoCompleteBoxItemStyle in the built-in Themes but it seems like this style is set globally. Which property of the RadAutoCompleteBox can I use to override this default style?

Thanks for your help
Matthias

RadImageEditorUI doesn't accept databinding

Hi all of you,

I'm using this control under trial license. I'm trying to do a very simple binding but it doesn't work at all:

xaml header:

Here you can see the reference to one of my RESX files (I've got one for English and another one for Spanish where every key is named alike.
Names of resources files:

MasterGIT.resx and MasterGIT.en.resx

This line uses one RESX under criteria language:

ResxExtension.DefaultResxName="GIT_CuadroMando.MasterGIT" Language="{UICulture}"

<Window

ResxExtension.DefaultResxName="GIT_CuadroMando.MasterGIT" Language="{UICulture}"

Title="{Resx TitleGestorDocumental}" Height="701" Width="1000" ResizeMode="CanResize" WindowStyle="ToolWindow">

<telerik:RadImageEditorUI x:Name="BodyWorkAndPaintingTool" Grid.ColumnSpan="4" Margin="10,49,33,10" Grid.Row="1" Grid.RowSpan="4">

<telerik:RadImageEditorUI.ImageToolsSections>

<telerik:ImageToolsSection Header="{Resx Disenador_Blur}" >

<telerik:ImageToolItem ImageKey="Resize" Text="Resize" Command="commands:ImageEditorRoutedCommands.ExecuteTool">

<telerik:ImageToolItem.CommandParameter>

<tools:ResizeTool x:Name="resizeTool"/>

</telerik:ImageToolItem.CommandParameter>

</telerik:ImageToolItem>

<telerik:ImageToolItem ImageKey="Resize" Text="Canvas resize" Command="commands:ImageEditorRoutedCommands.ExecuteTool">

<telerik:ImageToolItem.CommandParameter>

<tools:CanvasResizeTool/>

</telerik:ImageToolItem.CommandParameter>

</telerik:ImageToolItem>

code-behind:

Private Sub Window_Loaded(sender As Object, e As RoutedEventArgs)

CultureManager.UICulture = Thread.CurrentThread.CurrentCulture

' Thread.CurrentThread.CurrentUICulture = New CultureInfo("es")

End Sub

ConnectionManipulationCompleted issue

private void diagram_ConnectionManipulationCompleted(object sender, ManipulationRoutedEventArgs e)
{
Here, e.Connector may be null. Why?!
}

Some times, when I drag a connection from a node and then release it before attaching to another connector, the ConnectionManipulationCompleted event is fired with its Connector set to null. It happens maybe 1 out of 10 tries, but after it has occurred it seems to happen more often until I press ESC or perform some other reset operation.

How should I interpret this? Is it a bug or is this a valid state?

UPDATE:
This event is usually not fired when I do the above. Only when it does indeed fire, this weird state is seen. I believe this event is erroneously called from within your code. Also, e.ManipulationStatus is set to ManipulationStatus.Moved. Obviously, I did not move a connection...

Overriding Default Style for AutocompleteTextBox

In all the built in .net WPF controls, you may override the default style, and specify your own custom template. In my usage, it allows me to view a Textbox as a Label, have a button clicked to switch the mode to Edit mode, and switch the style to change the control back to a TextBox.

When I attempt to do the same thing for the Telerik - RadAutoCompleteTextbox, with this style, I get the following error (view mode)

<Style x:Key="RadAutoCompleteBoxViewMode" TargetType="{x:Type telerik:RadAutoCompleteBox}">

<Setter Property="OverridesDefaultStyle" Value="True" />

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type telerik:RadAutoCompleteBox}">

<Label Content="{Binding SearchText, RelativeSource={RelativeSource AncestorType=telerik:RadAutoCompleteBox}}" Style="{StaticResource FormFieldReadOnly}" />

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

Object reference not set to an instance of an object.
at Telerik.Windows.Controls.RadAutoCompleteBox.InitializeBoxesItemsControl() in c:\TB\135\WPF_Scrum\Release_WPF\Sources\Development\Controls\Input\AutoCompleteBox\RadAutoCompleteBox.cs:line 1067

Is there something I'm missing? Is there another way to accomplish this goal ? Should not the concept of lookless controls be supported?

thanks!

[Solved] AutoClose RadWindow

I've been using the "WPFDialogManagement" controls for popup message windows previously and they allow for command like this:

dialogWait = dialogManager.CreateWaitDialog("We're good to go. This message will self destruct in 3 seconds...", DialogMode.Ok);
dialogWait.Show(() => Thread.Sleep(3000));

This pops up the message and then auto closes after 3 seconds if the "ok" button isn't pressed.

Is it possible to get a similar behavior with the RadWindow.Alert or by another means?

Thanks...

I embedded that control in a Window in my WPF desktop project and sometimes everything is stuck and I need to close my IDE throught Task Manager.

<Grid.Background>

<LinearGradientBrush EndPoint="0.985,0.415" StartPoint="0.053,0.415">

<GradientStop Color="#FF99B4D1" Offset="0"/>

Thanks in advance,

Hello,

I'm using the combobox in this example inside a grid as a celledittemplate:

http://www.telerik.com/community/forums/silverlight/combobox/multiselect-option-in-combo-box.aspx

I'm kind of new to wpf binding and I've tried a lot of things to get this done, but cannot achieve my goal.
please help.

Here's the column definition, Choices is the property I need to bind the results of the checked items.

    
            <telerik:GridViewDataColumn Header="Choices"   
        
               DataMemberBinding="{Binding Choices, Mode=TwoWay}">  
        
               <telerik:GridViewDataColumn.CellEditTemplate> 
        
                  <DataTemplate> 
        
                     <telerik:RadComboBox x:Name="ChoicesCombo"
