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.

How to limit available weekdays in Telerik WPF RadDatePicker within RadGridView based on model configuration

I need to limit available weekdays to select in Telerik WPF RadDatePicker. This RadDatePicker is in column of Telerik WPF RadGridView. Configuration of weekdays available to select should be different for each row.

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

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">

<telerik:RadRibbonBackstageItem Header="New" telerik:KeyTipService.AccessText="N" Click="RadRibbonBackstageItem_Click" />

<telerik:RadRibbonBackstageItem Header="Open" telerik:KeyTipService.AccessText="O" Click="RadRibbonBackstageItem_Click_1"/>

</telerik:RadRibbonBackstage>

</telerik:RadRibbonView.Backstage>

<telerik:RadRibbonTab Foreground="Black" Header="Edit" telerik:KeyTipService.AccessText="E">

<telerik:RadRibbonGroup Header="Clipboard" telerik:ScreenTip.Title="Clipboard"

telerik:ScreenTip.Description="Bla Bla"

telerik:KeyTipService.AccessText="FO">

<telerik:RadRibbonGroup.Variants>

<telerik:GroupVariant Variant="Medium" Priority="0"/>

</telerik:RadRibbonGroup.Variants>

<StackPanel Orientation="Horizontal">

<telerik:RadRibbonButton Text="Paste"

Size="Large"

telerik:ScreenTip.Title="Paste"

Click="RadRibbonButton_Click"

telerik:ScreenTip.Description="Paste"

telerik:KeyTipService.AccessText="V">

</telerik:RadRibbonButton>

</StackPanel>

</telerik:RadRibbonGroup>>

</telerik:RadRibbonTab>

</telerik:RadRibbonView>

<Grid Grid.Row="1">

<TextBox Width="100" VerticalAlignment="Top" HorizontalAlignment="Left"/>

</Grid>

</telerik:RadRibbonWindow>

Run the project, and click the TextBox so it will get keyboard focus. Press the Escape key, and you'll see what I mean.

Is there any workaround?

Can you please fix it.

Thanks

Manual setting merge field result

I'm trying to set merge field values manually and I can't get anything to work, or find anything indicating how I can do this directly. Here's an example of my code:

                        var span = new Span("Testing");
                        var fragment = DocumentFragment.CreateFromInline(span);

                        start.Field.SetFragmentByDisplayMode(FieldDisplayMode.Result, fragment);

start.Field is a MergeField, and basically other than the end result being blank. When I look at the MergeField objects properties after making this call I see that the ResultFragment shows as empty. What am I missing here? If this won't work is there some way to just remove the field and insert my text?

I realize the documentation is angled towards mail merge but my situation doesn't make that feasible.
