I'm implementing a quite complex filter definition. I have to add a custom filter with 2 controls in it

Starting from this sample http://demos.telerik.com/silverlight/#DataFilter/CustomEditors

The class I'm using to save the values is this:

    public class DeltaTime
    {
        public TimeSpan Start { get; set; }
        public TimeSpan End { get; set; }
    }

And the xaml template is:

                    <DataTemplate x:Key="DeltaTimeTemplate">
                        <StackPanel Orientation="Horizontal" DataContext="{Binding Value, Mode=OneWay}">
                            <telerik:RadTimePicker SelectedValue="{Binding Start, Mode=TwoWay, FallbackValue={x:Null}}" DateTimeWatermarkContent="Start" />
                            <telerik:RadTimePicker SelectedValue="{Binding End, Mode=TwoWay, FallbackValue={x:Null}}" DateTimeWatermarkContent="End"  />
                        </StackPanel>
                    </DataTemplate>

It seems working, or at least the controls is displayed correctly. But, when I'm passing all filters, this filter value is <Unset>

We have a Telerik WPF application that uses StyleManager at the moment, after changing to the noXml Binaries, we got the user controls working but the modules do not show anymore and no error is given, this particular application is too complex to create a sample project for, I wanted to know if maybe someone has encountered something like this or maybe the is a way to overcome it.

I have used fussion log, I have double checked all the implementations and the only thing i did was define the Theme in the App.Xaml using the dierct copy of the xaml files or using the Theme dll. The theme in question is the WPF 4.5 Telerik.Themes.Green.DLL. 

I am failry new to telerik and WPF and MVVM, so please forgive my lack on knowledge, I have a Shell that that uses directory searching to find modules that I can load into its regions, Each module has a few views that are have top level elementa radSplitContainer, A few of those views can be opened at one time and each has custom logic when the RapPane is closed

What I did was used event aggregation to publish the closed event, but I cant find a way to know what view called the close event without creating a reference to my view inside my viewmodell. I have tried 

to try and create an interface that both the view and viewModel would implement, but i can never find an object that supports the interface I just created or anyway I can tap into the close event  from the view instead of from the RapDock control.

Is there any example which demonstrates how to create and work with a custom third-party spell checker using Open Office?

I tried https://github.com/telerik/xaml-sdk/tree/8a76eafd48278d8278b4b61d1c2aeb3c0ac8750d/RichTextBox/NHunspellSpellChecking, but it is not working properly (all words are marked as incorrect). I used en_US.aff and en_US.dic files from en_us.oxt (http://extensions.openoffice.org/en/project/us-english-spell-checking-dictionary).

Hello Telerik,

I want to display a ToolTip when mouse passing on specific cell (pink background cell), but I don't find the corresponding event.

I tried to use the CurrentCell but it's every time null. After, I tried to use the casted row to use its Properties Item CurrentCell to get attribut ('IsDiscontinuite') but the result it's every time true.

My work :

So, I want to know what is the find event for this problem ?

Thank you very much !

Valentin.

I would like to handle a double click event on a connector. For shapes there is a OnShapeDoubleClicked, but I can't seem to find a way of handling the double click of an connector.

I tried handling the double-click event of the diagram itself, but can't seem to find the connector at the click location.

Is there an easy way to achieve this?

This is my first time using the masked input and I could use some help. I don't want the placeholder, so I'm using Mask="". In this example, I want to restrict to positive integers only (or blank if it's an optional input). I can restrict the numeric version to digits only, but how do I prevent the negative sign?

I would actually prefer to use the normal masked input and simply limit it to the characters 0-9. However when I use Mask="", I have not been able to restrict the inputs using the FormatString. It's still allowing me to type anything.

I have the following exception popping up from time to time when I scroll fast or use sliders in RadGridView.

Exception: Exception thrown: 'System.Xaml.XamlParseException' in #####.exe

I simply host RadGridView in UserControl:

    <telerik:RadGridView ItemsSource="{Binding #######}"
                         IsReadOnly="True"
                         RowIndicatorVisibility="Collapsed"
                         AutoGenerateColumns="False"
                         ShowGroupPanel="False"
                         GridLinesVisibility="Both"
                         ClipboardCopyMode="All"
                         SelectionMode="Extended"
                         FrozenColumnCount="1"
                         CanUserFreezeColumns="False"
                         Background="Transparent"
    >
        <telerik:RadGridView.Columns>
