How to set the background color consistent with current theme

Hi

I'm trying to set the background color of a Grid (LayoutRoot) of a RadWindow consitent with application theme (that could be changed); RadWindow has alway a white background color despite any ApplicationTheme I could set.
Currently I'm adding a dummy element

<telerik:RadMenu Name="radMenu" Visibility="Collapsed" Width="0" Height="0"/>

and copy color from radMenu.

layoutRoot.Background = radMenu.Background;

Is there a better way to do that?

Thanks
Ivano

XAML designer crashes. Complains about 'InvertedBooleanToVisibilityConverter'

I have some Telerik controls in my XAML. When I load the designer, it throws an exception:

System.Exception
Cannot find resource named 'InvertedBooleanToVisibilityConverter'. Resource names are case sensitive.
   at System.Windows.StaticResourceExtension.ProvideValueInternal(IServiceProvider serviceProvider, Boolean allowDeferredReference)
   at System.Windows.StaticResourceExtension.ProvideValue(IServiceProvider serviceProvider)
   at MS.Internal.Xaml.Runtime.ClrObjectRuntime.CallProvideValue(MarkupExtension me, IServiceProvider serviceProvider)

I have referenced Telerik.Windows.Controls.dll. Not sure what's causing this as "InvertedBooleanToVisibilityConverter" cannot be found in my source code, but it is indeed present in your WPF examples...

Also, I do have this in my app.xaml:

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/System.Windows.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Chart.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Data.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Diagrams.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Diagrams.Extensions.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Docking.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

How to Complete Cell Edit in Code?

Quick question: Trying this out to make a quick demo and noticed that if you're editing a cell and haven't hit enter to complete then that content doesn't get saved as part of an export. It appears the control also doesn't auto complete the edit when it loses focus for say clicking a save button.

So how do I code it so when the control loses focus or some other event occurs that it completes the in progress cell edit and thus the whole thing will get saved?

Thanks

RadRichTextBox copy&paste of a custom InlineUIContainer object

Hi,
I'd like to know how I can use the copy and paste on objects of type custom using InlineUIContainer class.
I did some tests, but I could not duplicate the object, also using an override CopyableInlineUIContainer with the functions CopyPropertiesFromOverride/CopyContentFromOverride.

The object of type InlineUIContainer contains a control RadButton whose content is an image. I also linked to the button RadButton an event MouseDoubleClick to show custom dialog box.

This is a sample code:

string controlName = "PLACEHOLDER_" + getNewId(); // ex. PLACEHOLDER_1

string controlTag = getNewTag(); // ex. 100231

var button = new RadButton

{

Name = controlName,

Tag = controlTag, // this tag is used to retrieve custom properties from database

Width = 100,

Height = 32,

};

// add the image to content

button.Content = this.getCustomUIElementByPlaceholder(message, controlName);

button.MouseDoubleClick += SelectPlaceHolder; // event fired when user doubleclick the button

// create the UI element

// new class with copyable=true override

var container = new CopyableInlineUIContainer { UiElement = button, Width = button.Width, Height = button.Height, Tag = controlName };

// original code

// var container = new InlineUIContainer { UiElement = button, Width = button.Width, Height = button.Height, Tag = controlName };

// invoke the insert method

// Note: editor if a WPF control of type RadRichTextBox

editor.InsertInline(container);

// add a text coomment

string sContentComment = "Custom placeholder NAME " + controlName + " TAG " + controlTag;

var comment = new Comment(sContentComment) { Name = string.Concat("m", controlTag) };

editor.ShowComments = true;

var startPosition = editor.Document.CaretPosition;

var endPosition = new DocumentPosition(startPosition);

startPosition.MoveToCurrentWordStart();

endPosition.MoveToCurrentWordEnd();

editor.Document.Selection.AddSelectionStart(startPosition);

editor.Document.Selection.AddSelectionEnd(endPosition);

editor.Document.InsertComment(startPosition, endPosition, comment);

If I try to duplicate the object, only the comment is actually copied.

Is there any solution for this?

Thanks,

Crash on delete range containing table

If I try to delete a range containing a table, either via setting a selection and Document.Delete(false) or via Document.Delete(start, end), I get an InvalidCastException:

Unable to cast object of type 'Telerik.Windows.Documents.Layout.TableLayoutBox' to type 'Telerik.Windows.Documents.Layout.ParagraphLayoutBox'.

   at Telerik.Windows.Documents.Model.RadDocument.DeleteParagraphsInRangeInternal(DocumentPosition fromPosition, DocumentPosition toPosition) in c:\TB\102\WPF_Scrum\Release_WPF\Sources\Development\Documents\Core\Model\RadDocument.cs:line 4530

Are there any alternatives or workarounds? Or am I doing something wrong?
