support for upcoming Silverlight 5 Beta

[Sean]

Hi Telerik,

Now that the Silverlight 5 Beta has been announced for release next week, does your team have a timeline for beta controls to support it?  
Thanks,

Sean Elliott

Hello Sean,

 We believe that our current Silverlight assemblies will work normally with the upcoming Silverlight 5 Beta. Later this year when we start adding Silverlight 5 specific features we will provide native Silverlight 5 assemblies. 

All the best,

It looks like they have enhanced the DataGrid control, because I'm trying to use the newly feature from Silverlight 5 to create dynamic properties at runtime and while with the DataGrid it works fine, the GridView from Telerik doesn't populate the columns.

This article refers to the feature I'm talking about: http://blogs.msdn.com/b/silverlight_sdk/archive/2011/04/25/binding-to-dynamic-properties-with-icustomtypeprovider-silverlight-5-beta.aspx

Hello,

 Indeed later this year (as I've posted earlier) we will add SL5 specific features ... like this for example.

"We believe that our current Silverlight assemblies will work normally with the upcoming Silverlight 5 Beta."

Unfortunately they don't. :(

I can't open a UserControl in the Blend 5 Preview that contains a RadTabControl.
I keep getting an error "Error HRESULT E_FAIL has been returned from a call to a COM component."

Any ideas?

cheers

Hello,

 Can you check the inner exception for more info?

Hi Vlad,

Thanx for your reply!

InnerException: None.

And the Xaml ist super-simple.

 

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    mc:Ignorable="d"
    x:Class="MEFSample.TabControlError"
    d:DesignWidth="640" d:DesignHeight="480">

    <Grid x:Name="LayoutRoot">
        <telerik:RadTabControl HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
            <telerik:RadTabItem telerik:HeaderedContentControl.Header="RadTabItem">
                <Grid Background="Transparent"/>
            </telerik:RadTabItem>
        </telerik:RadTabControl>
    </Grid>
</UserControl>

Is that reproducible for you?
Are you interested in a screenshot?

cheers,
Thomas

Hello Thomas Mutzl,

Please accept my apology for the delayed response.

I tested the RadTabControl in ExpressionBlend5 Preview and it works as expected. However, I noticed that you are trying to set the RadTabItem Header using the telerik:HeaderedContentControl.Header. Can you try setting it through the RadTabItem Header property instead. I attached my test application just in case. Let me know if it works for you or if I am missing something.

Hello Tina,

Yup - I can confirm that it opens in Expression Blend 5 correctly.
Even my code from last week opens no correctly in design view. I have no idea what went wrong when I wrote the post.

Thanks for your answer!

After installing SL5 beta and tools, silverlight plugin crashes when I try to browse your demos. All other SL apps seems to be working just fine. I'm experiencing this problem on all machines with SL5 beta (32-bit and 64-bit Win XP).

Hello Andrew,

Have you tried running the demos with Internet Explorer? I tried and they work okay. 

Kind regards,

[Andrew]

I get the same error in FF, Chrome, or IE. The very same thing happens on my home computer; they both have SL5 beta and tools and your samples used to work before I installed it. Is there anything I can do to diagnose the problem? I'm surprised that no one else seems to be having this problem...

[Milan]

Hi Andrew,

I am afraid that there are no specific steps that I can recommend you to try. We will keep on trying to reproduce the error. 

All the best,

Hi
We are currently working on supporting Silverlight 5 in our product and in that context are seeing a serious problem with the radrichtextbox.
The problem is as follow: If you immediatly start typing (fast) after the app/richtextbox has loaded, the whole browser goes down. If you type one character, wait a few secs and then start typing everything works just fine.
We see this on both Macs and pc's (with SL5).
We manage to reproduce the problem in a simple test solution containing nothing but the richtextbox (link below).
We use version 2011.2 712 (have also tested with your latest internal build, without success).

We know that SL5 beta isn't officially supported, but can you help us with this?
Is this a known issue?
Is there any (temporarily) workaround?

Link to the test solution (without the telerik dll's): http://db.tt/GW3CfbA

Thank you!

I have managed to create a workaround to get around the problem.
This is really a hack, but it works :-)

So, in the loaded event of the editor, I set some content. Then I create and set a timer to do a callback after 10ms I clear the textbox. After this, everything seems to work just fine.

Thought this could be of interest for you..

Here's the code behind on the page hosting the RadRichTextBox:

public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private Timer m_timer;

        private void RadRichTextBoxLoaded(object sender, RoutedEventArgs e)
        {
            radRichTextBox.IsReadOnly = true;
            radRichTextBox.Document = (new TxtFormatProvider()).Import("loading...");
            m_timer = new Timer(RadRichTextBoxLoadedComplete, sender, 10, Timeout.Infinite);
        }

        private void RadRichTextBoxLoadedComplete(object sender)
        {
            Dispatcher.BeginInvoke(() =>
                                       {
                                           radRichTextBox.Document = (new TxtFormatProvider()).Import("");
                                           radRichTextBox.IsReadOnly = false;
                                       });
            m_timer.Dispose();
        }
    }

Hi Øivind,

Thank you for following up on this issue. It is good to know that you have managed to workaround the problem for now, even if it is a hack.
We will continue to look into the behavior of the rich text box with Silverlight 5 and try to solve the issues on our end whenever such appear.

Kind regards,
Iva
