DataContext of RadContextMenu

Hello all
I have difficulty with RadContextMenu and particulary DataContext property.
I have a RadWindow ("mainWindow") who contain a RadTreeView. RadTreeView expose Items by HierarchicalDataTemplate, that this items who contains RadContextMenu.
My problem : DataContext of RadContextMenu is always DataContext of Item and I want the DataContext of the RadWindow.
I show you my XAML :

<telerik:RadWindow x:Class="Vue.MainWindow" x:Name="mainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">

<Grid x:Name="mainGrid">

<telerik:RadTreeView x:Name="radTreeView" Grid.Row="1" ItemsSource="{Binding TypeDatabases}"

<telerik:RadTreeView.Resources>

<HierarchicalDataTemplate DataType="{x:Type Modele:EntiteDatabase}" ItemsSource="{Binding Tables}">

<StackPanel Orientation="Horizontal" Height="25">

<Image Source="{Binding SourceIcone}" Stretch="Fill" Height="16"/>

<TextBlock Text="{Binding Description}" TextAlignment="Left" VerticalAlignment="Center" />

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu InheritDataContext="False" DataContext="{Binding DataContext, ElementName=mainWindow}">

<telerik:RadMenuItem Header="Connexion" Command="{Binding OpenDatabase}" />

<telerik:RadMenuItem Header="Déconnexion" Command="{Binding CloseDatabase}" />

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</StackPanel>

</HierarchicalDataTemplate>

</telerik:RadTreeView.Resources>

</telerik:RadTreeView>

</Grid>

</telerik:RadWindow>

In this solution, I have an error : "cannot find ElementName=mainWindow" and I don't understand
I tried others methods to retrieve the DataContext (Tag in my StackPanel, ....)
Thank to you for help

PS : I am sorry for my english

Filter DateTime column by range

Hi,

I am using RadGridView to display some data and one of the columns is of type DateTime. Filtering mode is set to FilterRow. How can I filter the column by date range like I can in ASP.NET AJAX RadGrid?

Changing filtering mode to popup is not an option for me, I need it to be filter row.

I would also like to know how to hide the filter button and set one default filter function like contains? All of these things can be easily done on web RadGrid, but I am not able to do it with WPF RadGrid.

Thank you,

Patrik

How to show dropdown when item list is empty

The RedComboBox displaying list of items for selection and this list will be empty to start with. If this list is empty, user should see an empty drop down so that the User knows there is nothing to select. With my code below, I just see a small 2 pixel line below combo, this give an impression to user that something is wrong with application. If you use windows provided ComboBox then it will a empty dropdown and we want the same behavior from RedComboBox.

How can I enable dropdown even if there are no items in the list?

<RadComboBox

HorizontalAlignment="Left"

Margin="1,1,0,1"

VerticalAlignment="Center"

Name="comboname"

SelectedItem="{Binding Path=Item, Mode=TwoWay}"

ItemsSource="{Binding Path= ItemList}"

IsReadOnly="False"

EmptyText=" - select an item - "/>

ComboBox
