I which control are we supposed to host the RibbonView?
The documentation uses a UserControl.

In my test this results in navigation arrows being displayed and the Quick Access Toolbar not being shown in the windows title bar.
See screenshot attached.

<UserControl x:Class="MainWindow"

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

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

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

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

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="300">

<Grid>

<Grid x:Name="LayoutRoot" Background="White">

<telerik:RadRibbonView>

<telerik:RadRibbonView.QuickAccessToolBar>

<telerik:QuickAccessToolBar>

<telerik:RadRibbonButton Text="Save" Foreground="White"/>

</telerik:QuickAccessToolBar>

</telerik:RadRibbonView.QuickAccessToolBar>

</telerik:RadRibbonView>

</Grid>

</UserControl>

Are we supposed to use the RibbonWindow?

Making RadRibbonWindow IsWindowsThemeEnabled = false

I have seen that the documentation says - http://www.telerik.com/help/wpf/radribbonview-ribbon-window-wpf.html

RadRibbonWindow.IsWindowsThemeEnabled = false;

and setting a theme to make the ribbonwindow theme aware. I want exactly the documentation example. But I didn't find any such property in Q2 release of 2011 edition. Can you please correct me if was wrong there?

vertical cell joining

my customer would like to have a visual indicator, when vertical cells contain the same value. I've found a way to get it to work basically but some of my code looks pretty awfull.

<DataTemplate x:Key="Group_GridCellTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="auto"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<style:CRowJoiner Template="{StaticResource MM_RJI}">

<style:CRowJoiner.DataContext>

<MultiBinding Converter="{StaticResource RJ}">

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}" Path="Column" />

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}" Path="ParentRow" />

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}" Path="Value" />

</MultiBinding>

</style:CRowJoiner.DataContext>

</style:CRowJoiner>

<ContentControl Grid.Column="1" Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}, Path=Value}" ContentTemplateSelector="{StaticResource GCTS}" />

</Grid>

</DataTemplate>

as you can see i am using the gridviewcell extensively. is it possible to simply pass the gridviewcell as a whole to a converter? currently i am passing 3 properties from the same object and thats just stupid. my converter uses the information provided to do the cell joining, its not exactly simple though.

X Axis - Text Wrap?

I have a Bar series and the X axis contains the description of each bar. Some of the text is a bit long and runs into the text of the bar next to it. Does RadChart (2011 Q3) support text wrapping on the X axis? I don't see a property for it.

Thanks very much.

Filter Descriptor Limit?

Is there a limit to the number of FilterDescriptors that can be added to the FilterCollection? I seem to be receiveing a StackOverflowException in System.Core.dll if i try to add a significant number.

I need to limit the records in my Grid based upon specific ID numbers, so I am trying to add a filter desciptor for each ID to have it show only those records. My Grid has about 53,000 records, and in one example, I have 17,151 records that I need to display. How can I handle this? It works if i don't have a large number of results (i'm unsure of what the record limit before i get the error is)

I am just declaring a filter descriptor like this:
Dim filterDescriptor As New FilterDescriptor("ID", FilterOperator.IsEqualTo, id)
And then adding it to the collection

Any way to make Month View slots (Saturday & Sunday) "hidden" or "minimized"? Any way to set the width of slots or make it resizable as ScheduleView?

Hi all,

I'm working on RadScheduleView to resemble a Month Calendar, and the only option is to use Month View Definition.
In my applicaiton, users only have Appointments on working days (Mon to Fri) and the screen space of Sat/Sun empty slots on Month View will be wasted.

Question (1):
I read my posts in this Forum and found out hiding Saturday and Sunday in Month view is not supported by RadScheduleView.
Then I try to find a work-around solution to set Styles of TimeRulerMonthViewItem and TimeRulerMonthViewGroupItem . This is what I have done, setting Visibility property binding to a convert to return Collapsed for Sat and Sun:

<telerik:OrientedTimeRulerItemStyleSelector x:Key="TimeRulerItemStyleSelector"

MonthViewGroupStyle="{StaticResource timeRulerMonthViewGroupItemStyle}">

<telerik:OrientedTimeRulerItemStyleSelector.MonthViewTickStyle>

<Style TargetType="local:TimeRulerMonthViewItem">

<Setter Property="Background" Value=

"{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.DateTime.Date, Converter={StaticResource ResourceKey=calendarDateColorConverter}}"

/>

<Setter Property="Visibility" Value=

"{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.DateTime.Date, Converter={StaticResource ResourceKey=calendarDateCollapsedConverter}}"

/>

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="local:TimeRulerMonthViewItem">

<Border Background="{TemplateBinding Background}"

BorderBrush=

"{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.DateTime.Date, Converter={StaticResource ResourceKey=currentDateCalendarDateColorConverter}}"

BorderThickness="2" >

<Grid Background=

"{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.DateTime.Date, Converter={StaticResource ResourceKey=calendarDateColorConverter}}"

>

<telerik:RadButton Padding="0" VerticalAlignment="Top" Height="22" Command="local:RadScheduleViewCommands.SetDayViewMode" CommandParameter="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.DateTime.Date}"

Background=

"{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.DateTime.Date, Converter={StaticResource ResourceKey=plainCalendarDateColorConverter}}"

Style="{StaticResource ResourceKey=GoToDayButtonStyle}">

<ContentPresenter Margin="{TemplateBinding Padding}" />

</telerik:RadButton>

<telerik:RadToggleButton Visibility="{Binding ExpandButtonVisibility}" IsChecked="{Binding IsExpanded, Mode=TwoWay}" HorizontalAlignment="Right" VerticalAlignment="Bottom"

Content="More..." FontSize="9" />

</Grid>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</telerik:OrientedTimeRulerItemStyleSelector.MonthViewTickStyle>

</telerik:OrientedTimeRulerItemStyleSelector>

And I set the Border visibility property as well with the same binding and converter. The outcome of the ScheduleView is showing empty slots but Sat/Sun are still there and Appointments for Sat/Sun on empty slots.
Is there any thought on how to actually hide and making the slot collapsed?

Question 2:
Is there any way to set the width and height of the slot in Month View?
I had customized Appointment template which shows at least three lines of information for an Appointment. And I don't want the user to always click Expand button to see all the details. Is there any way to always show "Expanded" slot in Month View?

Many many thanks!

Frankie
