MainWindow "losts" focus after child RadWindow is closed

Hello,

I have a standard WPF MainWindow, from that I open a modal RadWindow (using .ShowDialog()). When the user clicks on one button I close the dialog and open a new non-modal RadWindow:

ConfigurationComparerWindow comparerWindow = new ConfigurationComparerWindow() { Owner = Application.Current.MainWindow, };

comparerWindow.Show();

//comparerWindow.Closed += (s, a) => { Application.Current.MainWindow.Focus(); };

This works just fine.

But if the user closes the second window I would expect that the MainWindow receives the focus. Instead the MainWindow is sent to back. If I uncomment the Closed event handler it works as I expected.

What is the preferred way of doing this?

Thanks,
Zoltan

RTF containing protected text does not make protected text readonly.

I have below rich text,

{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Times New Roman;}{\f1\fnil\fcharset0 Tahoma;}}
\viewkind4\uc1\pard\protect\f0\fs22 This is protected text\protect0\f1\fs16\par
}

It contains "\protect" tag which indicates the text between this tag is protected and cant be edited.

But when I bind this RTF to RadRichTextBox, it displays the text correctly. But it loses the protection. It does not make the text read-only.

How to make this text read-only?

MailMerge produces identical documents with identical addressee

Dear support,

we are facing rather often but nevertheless unpredictably the problem that the mail merge functionality produces identical documents. This is the part of code

01.public static IList<object> GetMailMergeBinaryResultDocuments

02. (byte[] source, IEnumerable mailMergeDataSource)

03.{

04. if (mailMergeDataSource == null)

05. {

06. throw new ArgumentNullException("mailMergeDataSource");

07. }

08.

09. RadDocument masterDocument = XamlFormatProvider.Import(source);

10. masterDocument.MailMergeDataSource.ItemsSource = mailMergeDataSource;

11. RadDocumentEditor radDocumentEditor = new RadDocumentEditor(masterDocument);

12.

13. radDocumentEditor.ChangeAllFieldsDisplayMode(FieldDisplayMode.Result);

14.

15. List<object> resultDocuments = new List<object>();

16. masterDocument.MailMergeDataSource.MoveToFirst();

17.

18. do

19. {

20. resultDocuments.Add(masterDocument.MailMergeCurrentRecord());

21. }

22. while (masterDocument.MailMergeDataSource.MoveToNext());

23.

24. return resultDocuments;

25.}

where we know that different mail merge information was passed but for some reason was not processed correctly.

Can you help?

Regards Jo

Arrows on a map line

Hi,

is there any easy way to show arrows on a mapline? The alignment should be centered.
Please have a look on my attached example delivery_network.png.

Maybe could caluclate the mid point of two geo coordinates and attach a custom node, but how could i bind the transformation to the edge line?

<telerik:RadMap Provider="{Binding MapProvider}" Center="{Binding Center}">

<telerik:InformationLayer ItemsSource="{Binding Edges}">

<telerik:InformationLayer.ItemTemplate>

<DataTemplate>

<telerik:MapLine Point1="{Binding SourceLocation}" Point2="{Binding TargetLocation}" Stroke="Black" StrokeThickness="2" />

</DataTemplate>

</telerik:InformationLayer.ItemTemplate>

</telerik:InformationLayer>

<telerik:InformationLayer ItemsSource="{Binding Nodes}">

<telerik:InformationLayer.ItemTemplate>

<DataTemplate>

<Border Background="Transparent" telerik:MapLayer.Location="{Binding Location}">

<ToolTipService.ToolTip>

<ToolTip>

<ToolTip.Content>

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

</ToolTip.Content>

</ToolTip>

</ToolTipService.ToolTip>

<telerik:MapLayer.HotSpot>

<telerik:HotSpot X="0.5" Y="0.5" ElementName="Ellipse"/>

</telerik:MapLayer.HotSpot>

<Grid>

<Ellipse Fill="{Binding Fill}" Width="15" Height="15" x:Name="Ellipse" />

<TextBlock Text="{Binding Name}" Foreground="{Binding Foreground}" FontSize="14" FontWeight="Bold" Margin="0 0 0 50" />

</Grid>

</Border>

</DataTemplate>

</telerik:InformationLayer.ItemTemplate>

</telerik:InformationLayer>

</telerik:RadMap>

I've found something similar but it doesn't really help me because binding inside geometry group or segments is not supported.

Thanks for your help.

RadRibbonView with a command defined INSIDE a ViewModel outside MODULE

Hi there.

I'm trying with no success at the moment, to implement a simple PRISM application who uses a RadRibbonView. The complexity resides basically in the command being defined as a member of a ViewModel that belongs to a MODULE of this PRISM application:

Prism application contains:

Shell, with a RadRibbonView containing a RadRibbonButton with a command called AddNewEmployee

EmployeeModule, with a RadGridView whose DataContext is EmployeeViewModel

EmployeeViewModel, defines an AddNewEmployee command.

So, AddNewEmployee command must be called on RadRibbonView, who knows nothing (pretty much like Jon Snow) of the model used in the EmployeeModule.

p.s.: modules are being loaded using RadRibbonTabs, and in the first tab, theres the button who calls the AddNewEmployee command.

Question is: this can be achieved? it is possible?

regards,

Gonzalo.

RadTreeView is applying multiple selection when left-mouse button is down?

I upgraded my Telerik version from 2014.1.331.45 to 2016.2.606.45. RadTreeView Multiple selection mode was working just fine with the older version, multiple selection is applied only when using Ctrl and/or Shift key (as expected). But after upgrading, RadTreeView is applying multiple selection without clicking Ctrl or Shift key, which is strange. The code is the same before and after upgrading:

<telerik:RadTreeView x:Name="lstVariables" Padding="5" BorderThickness="0" Grid.Row="0" ScrollViewer.CanContentScroll="False" IsEditable="True" SelectionMode="Multiple" ItemsSource="{Binding LstAppDataSeriesGrouping}" IsDropPreviewLineEnabled="False" IsDragPreviewEnabled="True" IsDragTooltipEnabled="False" telerik:TreeViewSettings.DragDropExecutionMode="New" IsLineEnabled="True" IsSingleExpandPath="False" IsExpandOnSingleClickEnabled="True" IsDragDropEnabled="True"

KeyDown="lstVariables_KeyDown" ItemTemplateSelector="{StaticResource ItemDataTemplateSelector}">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu x:Name="radContextMenu" Opened="radContextMenuBasic_Opened">

<telerik:RadMenuItem x:Name="mnuEditVariableBasic" Height="23" Header="{Lang:LangCheck Edit}" Click="EditBasicVariable_Click">

<telerik:RadMenuItem.Icon>

<Image Source="{DynamicResource editseries}"/>

</telerik:RadMenuItem.Icon>

</telerik:RadMenuItem>

<telerik:RadMenuItem x:Name="mnuDelete" Height="23" Header="{Lang:LangCheck Delete}" Click="mnuDeleteBasic_Click">

<telerik:RadMenuItem.Icon>

<Image Source="{DynamicResource delete}"/>

</telerik:RadMenuItem.Icon>

</telerik:RadMenuItem>

<telerik:RadMenuItem x:Name="mnuRename" Height="23" Header="{Lang:LangCheck Rename}" Click="mnuRenameBasic_Click">

<telerik:RadMenuItem.Icon>

<Image Source="{DynamicResource rename}"/>

</telerik:RadMenuItem.Icon>

</telerik:RadMenuItem>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</telerik:RadTreeView>

Why I load diagram the whole picture zoom in first the zoom out?

hello,when I load diagram use code like this:

                    StreamReader streamReader = new StreamReader(diagramXmlFile);
                    string data = streamReader.ReadToEnd();
                    streamReader.Close();
                    this.ProjectImageDiagram.Load(data);

                    RadDocumentPane diagramPane = new RadDocumentPane();
                    DataTemplate doctabTemplate = (DataTemplate)CRWindow.TryFindResource("doctab");
                    StackPanel docTab = (StackPanel)doctabTemplate.LoadContent();
                   diagramPane.Header = docTab;
                   UserControl diagramUserControl = new UserControl(diagram, true);
                   diagramPane.Content = diagramUserControl;

And I add diagramPane to RadDocking-DocumentHost-RadSplitContainer-RadPaneGroup, but when I run the program and open this pane, I find that the diagram is zoom in first, and then zoom out to fit the window,why? Hope to answer, Thanks !

Custom Presenters Issue In Q2 2016 SP1

Hi,

We are using custom page presenters (from FixedDocumentPresenterBase),

We have updated the telerik dlls to the last version (2016.2.613) since then we are unable to see our pdfs correctly using the pdfviewer with our custom presenters.

Only the first page is displayed, the other ones are all blank.

Works fine with the default page presenter.

I think that it could be related to a new page caching optimization that has been implemented.

Is there a way to be able to use it in our custom page presenters or maybe a way to disable it ?

Regards,

PDFViewer
