Synchronised scrolling of two instances of Scheduleview control

I have two instances of the ScheduleView control on one page ( a bit like this demo: http://demos.telerik.com/silverlight/#ScheduleView/Grouping/Basics). Is there a way to synchronise the vertial scrolling of both controls e.g. Control 2 automatically scrolls vertically as Control 1 scrolls vertically. The page I am developing allows the user to compare two sets of daily appointments. It would be really useful if both calendars scrolled together.

Regards

Myles

PdfViewer not showing documents with Identity-H encoding

Hi,

I am getting pdf files in a byte array form from the MS Reporting Services PDF Rendering Extension 11.0.0.0. Fonts are embeded and everything works fine, but if there are some special characters like letters with apostrophe the document is not displayed. If I save that document and open it with Adobe Reader it looks fine. The only difference that i'm aware of is that this documet has also an embeded subset of type 'TrueType (CID)' with encoding 'Identity-H'. Verdana is the only font in the document. Is there a solution to this problem?

Thanks in advance

Used Old 2017 Telerik Silverlight UI for Excel File Exporter - Fails with Cannot Load Assembly Error

Hi Telerik,

I used the old Telerik Silverlight UI to create a simple *.exe file that creates an excel file. The *.exe uses .NET framework 4 and references the below libraries from the 2017 Telerik Silverlight UI:

using Telerik.Windows.Documents.Spreadsheet;

using Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.xlsx;

This old *.exe no longer works when run on newer Windows 64-bit consoles with .NET 4.5 Framework installed. The *.exe terminates with the below error stacktrace:

----------------------------

Could not load file or assembly 'System.Windows, Version=5.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.

at Telerik.Windows.Documents.Spreadsheet.Model.Workbook..ctor()
at OracleExcelExport.Program.ProcessConfigFile(String configFile) in C:\Users\183639\Documents\Visual Studio 2010\Projects\OracleExcelExport\OracleExcelExport\Program.cs:line 61
at OracleExcelExport.Program.Main(String[] args) in C:\Users\183639\Documents\Visual Studio 2010\Projects\OracleExcelExport\OracleExcelExport\Program.cs:line 30

------------------------------

I am thinking it maybe 32-bit to 64-bit compatibility problem. Either way, there is bad reference from Telerik.Windows.Documents.Spreadsheet.Workbook..ctor()

Let me know if you can help.

Localization support for separate nuget packages

What is the suggested way to use the built-in localization for separate nuget packages. I can't find any localization dll inside.

If i would use the big single nuget package the dll for my language is included. By the way, this is not an option to me.

Kind regards,

Enrico

RadTreeView Freeze/Delay when displaying a RadGridView in a Item

Hi,

We've been using a RadTreeView to display a RadGridView as one of its items, recently we updated to the latest Telerik Silverlight controls and there is a major delay in showing the RadGridView (previously it was pretty instant).

<telerik:RadTreeView Name="AlertTree"

HorizontalAlignment="Left"

Margin="0,0,0,0"

VerticalAlignment="Top"

IsVirtualizing="True"

telerik:TreeViewPanel.IsVirtualizing="True"

telerik:TreeViewPanel.VirtualizationMode="Standard">

The RadGridView only has 100 rows - it loads at normal speeds into the tree when collapsed (i.e. not visible). The problem occurs when the tree is expanded to display the RadGridView. The UI appears to freeze and to display the 100 rows with 6 columns takes a minimum of 10 seconds (previously 1 or 2). The memory also jumps considerably when RadGridView finally becomes visible.

// Create the grid view
RadGridView aGridView= new RadGridView();
aGridView.ItemsSource = new Telerik.Data.DataTable(e.Result);

// Attach the grid view to the Tree
RadTreeViewItem aItem = new RadTreeViewItem();
aItem .Header = " Header Info";
aItem .Items.Add(aGridView);

As mentioned before, this was working fine previously.

Thanks
Oliver

Best way to set MaxLength on GridViewDataColumn

The TextBox control has a useful property called MaxLength which limits how many characters you can enter in it.

There does not seem to be an obvious/simple way to do the same thing with a GridViewDataColumn.

The way I got this to work was:

<Controls:GridViewDataColumn DataMemberBinding="{Binding ProductCode,Mode=TwoWay}" Header="Product Code" Width="150">

<Controls:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<TextBox Text="{Binding ProductCode,Mode=TwoWay}" MaxLength="50"/>

</DataTemplate>

</Controls:GridViewDataColumn.CellEditTemplate>

</Controls:GridViewDataColumn>

Is there a better/simpler/less verbose way of achieving this?

Telerik Silverlight Bing Map No Longer Working

Hi. I have an old Silverlight application that uses the Telerik Silverlight Map control using the Microsoft Bing Map provider. Silverlight is obsolete, but we are trying to keep it running for as long as we can.

The Telerik Silverlight Bing Map stopped working. The map control loads, but no map is being displayed. A http packet trace shows an HTTP 404 error against http://dev.virtualearth.net when requesting clientaccesspolicy.xml. See screenshot:

Is there a way to fix this?

Pproblem with the Windows 7 theme

Hello,

I have an old Silverlight application using the `Windows 7` theme.

In this application, I'm using many controls and the `app.xaml` file contains the following theme files:

      <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/System.Windows.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.Docking.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.GridView.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.ImageEditor.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.Input.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.Navigation.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.RibbonView.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.RichTextBoxUI.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Controls.xaml" />
        <ResourceDictionary Source="/VisManager;component/Themes/Themes/Windows7/Telerik.Windows.Documents.xaml" />
      </ResourceDictionary.MergedDictionaries>

After installation Ui for Silverlight R1 2022 SP1, the application no more starts: it complains about a referenced static resource that is missing, in the `Telerik.Windows.Controls.RichTextBoxUI.xaml` file.

Replacing this file with the one from version R1 2022 makes it work again.

You should really test Silverlight application while you're adding new functions!
