Binding to an element in the RadPane.TitleTemplate

In my RadPane I have a Listbox that is part of a UserControl in the Content section that I need to bind to a ComboBox in the TitleTemplate section; is this possible? A co-worker suggested searching the visual tree but I'm hoping there's a better way. The code currently falls down on the ItemsSource binding in the UserControl. A XAML solution is preferred but code-behind is fine if that is what is required.

TitleTemplate:

<DataTemplate x:Key="TitleTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="Auto"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<ContentPresenter Content="{Binding}"/>

<StackPanel Orientation="Horizontal" Grid.Column="1">

<ComboBox x:Name="Top" ItemsSource="{Binding Source={x:Static TopLevelElements}}"/>

<ComboBox x:Name="Middle" ItemsSource="{Binding ElementName=Top, Path=SelectedItem.MiddleLevelElements}"/>

</StackPanel>

</Grid>

</DataTemplate>

UserControl:

<UserControl x:Class="BottomItemView">

<Border>

<ListBox x:Name="Bottom" ItemsSource="{Binding ElementName=Middle, Path=SelectedItem.BottomLevelElements}"/>

</Border>

</UserControl>

Code for customized RadPane:

Public Class CustomRadPane

Inherits RadPane

Public Sub New(ByVal title As Object)

MyBase.New()

Me.Title = title

Me.TitleTemplate = TryCast(FindResource("TitleTemplate"), DataTemplate)

Me.Content = System.Activator.CreateInstance(BottomItemView)

End Sub

End Class

ScheduleView Functionality

We are examining your ScheduleView control for a while. We are trying to adapt a special calendar named "Merch Calendar" to your ScheduleView. We think that ScheduleView is a good choice for us. In this adaption we need to customize your Rad ScheduleViewDefinitions section to fulfil our needs. If you look at the upper section of our attached screenshot you will see like 201151 201201 values. Their meanings are: 2011-2012 year information and 51-52 are week information. Additionally, size of the bars which corresponds to appointments should be resized by the users and we need to get these changing date values. In this context, how can we customize the ScheduleViewDefinition section.Will these modifications fulfil our needs or are there any other possible ways.
Thanks, best regards.

Drop Down Menu Styling

Hello,

I am trying to add a drop shadow to the Tab Control DropDownMenu. Currently, I am applying the drop shadow effect to the outermost border within "Telerik_Windows_Controls_TabControl:DropDownMenu" Control Template. The only way I have been able to make the effect visible is by increasing the margins around the containing grid. The problem with this is the margins now push the border/dropdownmenu away from the DropDownMenuButton, so it appears to be floating on its own. Applying a RenderTransform to compensate for the shift only cuts off the drop shadow effect. I have attached an image demonstrating this behavior.

<ControlTemplate TargetType="{x:Type Telerik_Windows_Controls_TabControl:DropDownMenu}">

<Grid x:Name="PopupContentElement"

Margin="40,0,40,80"

RenderTransformOrigin="0,0">

<Grid.RenderTransform>

<TranslateTransform X="-40" />

</Grid.RenderTransform>

<Border BorderBrush="#FF848484"

BorderThickness="{TemplateBinding BorderThickness}"

Background="White">

<Border.Effect>

<DropShadowEffect BlurRadius="40"

Color="Black"

Direction="0"

Opacity="0.85"

RenderingBias="Quality"

ShadowDepth="0" />

</Border.Effect>

Any suggestions how to achieve the drop shadow effect without destroying the layout?

Thanks,
Frankie

Is there a way to use masked inputs for a bound integer column

I have an object property that's an int32. It's really a duration-in-seconds, but for a variety of reasons we can't use a TimeSpan, which also seems not to be supported as a masked-input or column type by Telerik.

I'd like to be able to allow users to input time in minutes:seconds in a column that's bound to this property. When I tried it, I got conversion errors.

Is this supported directly? I'll also trying adding conversion properties to my partial classes (I'm using Entity Framework 4) and see if that works, i.e. binding to the conversion properties.

Multiple Collections for One Item

Hello,

I have been breaking my head over the following problem and I do not get it working fully.

I have a collection of Fase.
The Fase object Has three collectlions namely
Software
Training
Consultancy.

I want my treeview to look like this
Fase1
-Software
--Item1
--Item2
-Training
--Item1
--Item2
-Consultancy
--Item1
--Item2
Fase1
-Software
--Item1
--Item2
-Training
--Item1
--Item2
-Consultancy
--Item1
--Item2

These also all need different template but I am not able to figure out to get the first part working
Fase1
-Software
-Training
-Consultancy

Is it even possible what I try to create with my current dataobjects.

DataGrid with long description hang when scrolling

We have problems in scrolling datagrid with long description column. If the display value for a column is not too long, the scrolling is working properly. However if there is a long description shown in a column as shown in the attached screen, the screen will hang when scrolling in the datagrid and the WPF window cannot be recovered until closed and reopened. The no of records are not that large and are around 600 only. Below is the reference code. Please advice the solution.
