How to get the current style

I have a need to get the current style of a document. The GetCurrentSpanStyle method of RadRichTextBox is protected, so I cannot use this. The only way that I have been able to get the current style is to create a override of RichTextBoxCommandBase for this purpose.

public class GetCurrentSpanStyleCommand : RichTextBoxCommandBase

{

public GetCurrentSpanStyleCommand(RadRichTextBox editor) : base(editor)

{

}

protected override void ExecuteOverride(object parameter)

{

}

public Span ExecuteGetCurrentSpanStyle()

{

return base.GetCurrentSpanStyle();

}

Is there a better way to do this?

On using ItemsSource

I've created a class inheriting from RadPane, and I'm binding a list of istances of this class to the ItemsSource property of the RadDocking. If I add elements to the list and then update (fire the PropertyChanged event for the property) it works great, but it crashes when I try to delete an element from the collection and then refresh the property.

If I create a custom factory for the control and I override the RemovePane method, I get null pointers when the method is called.

Has somebody any idea of what I am doing wrong? I can provide a sample if needed.

Thanks!

Load next data during expand (XMLA)

Hallo,
We look for a component package in WPF for new ERP system. We want thin desktop and web client.
Now I analyze data binding of component for pivot table.
You have it perfectly solved in web package Kendo UI (http://demos.telerik.com/kendo-ui/pivotgrid/index). A next data are loaded only if user expands next level. Can I achieve this behavior in WPF?
In your WPF trials it seems that all data are loaded once and while expanding these are only shown. I try XmlaDataProvider (demo XmlaStyleRaggedHierarchies) and I defined expand behavior for collapse all levels.

I've created model with available weekdays configuration, but I don't know how to simply attach such functionality to RadGridView.

Thanks in advance for any help.

change the content of tab in SettingsPane depending on the Shape

Hello,

I have many different custom shapes.
I've added a new tab to the SettingsPane. How can I change the content of this tab depending on the custom shape that the user has dropped it or selected?
Any event for SettingsPane can help me?
I need event fires when I press the SettingsPane button!
I tried (PreviewAdditionalContentActivated) and (AdditionalContentActivated) but both are fired when I dropped any shape now when I press the SettingsPane icon.

Thank you

[Solved] RibbonView is taking focus when Escape is pressed

We use a custom autocomplete textbox, and it's been working fine with Telerik Controls from 2012.

We've recently upgraded the DLL, and I've noticed that there is a new problem. When the Autocomplete is focused and Escape is being pressed, the textbox still has logical focus, but the keyboard focus is lost (The cursor is still on the textbox, but it is not blinking anymore).

After debugging it, I've found out that KeyTipService.HandleEscape is being called, and this specific code takes the keyboard focus:

if (this.Ribbon != null)

{

#if WPF

Keyboard.Focus(this.Ribbon.SelectedTab);

#endif

if (this.Ribbon.IsBackstageOpen)

{

this.Ribbon.IsBackstageOpen = false;

}

I've tested this issue on a test project, and I can reproduce the issue, even with a regular textbox:

<telerik:RadRibbonWindow x:Class="RibbonTakesFocusFromAutoComplete.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<Grid x:Name="contentToDisable">

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<telerik:RadRibbonView Name="MainRibbon" HelpButtonVisibility="Visible" HelpCommand="{Binding ShellHelpFileCommand}" GotKeyboardFocus="MainRibbon_GotKeyboardFocus"

ApplicationName="Bob"

telerik:KeyTipService.IsKeyTipsEnabled="True"

MinimizeButtonVisibility="Visible"

Foreground="Black"

IsBackstageOpen="false"

IsMinimized="False">

<telerik:RadRibbonView.Backstage>

<telerik:RadRibbonBackstage telerik:KeyTipService.AccessText="F">
