I'm setting the PeriodEnd on the Timebar control without any time component, i.e. 3/7/2011 12:00:00 AM. When selecting dates on the UI, I can only select until 3/6/2011? Is there a way to change this to display/select the PeriodEnd being passed in? I'm by default selecting the full date range (PeriodStart - PeriodEnd).

Hello. I'm trying to change the standard behaviour of LeftClick (zoom) to RightClick, and also stop the event from firing on left click so I can set up my own behaviour. Is this possible?

Problem with tabbing in gridview

Hello,

I've got a problem with a gridview.

The first cell is set to IsReadOnly=true, so the cursor starts at the 2nd cell, but when I press tab the focus is on the "frame" of cell 3, not inside it, and i'm unable to tab to the next cell or type anything in the cell. I have to click with the mouse inside the cell, and then everything works fine.

I've attached 2 screen shots.

Any ideas/solutions to this problem?

Cheers

Hosting TreeView in WinForms Window - drag/drop does not work

We are hosting the RadTreeView in our application inside of a winforms window and the drag/drop functionality (exact same code) that works in a WPF does not work when hosted in a winforms window. Is there a reason for this behavior?

Thanks!

RadListbox + popup

Hi,

i'm using the example "RadListBox Drag and Drop":

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<Border Grid.Row="0" Height="22" BorderBrush="#FFD6D4D4" BorderThickness="0,0,0,1"

VerticalAlignment="Top" Background="#FFF7F7F7" HorizontalAlignment="Stretch">

<TextBlock Style="{StaticResource HeaderTextBlockStyle}" Text="Final tournament" Margin="6 2 2 2" />

</Border>

<telerik:RadListBox Grid.Row="1" AllowDrop="True" ItemsSource="{Binding GroupD}"

ItemTemplate="{StaticResource ListBoxItemTemplate}">

<telerik:RadListBox.DragVisualProvider>

<telerik:ScreenshotDragVisualProvider />

</telerik:RadListBox.DragVisualProvider>

<telerik:RadListBox.DragDropBehavior>

<telerik:ListBoxDragDropBehavior AllowReorder="True" />

</telerik:RadListBox.DragDropBehavior>

</telerik:RadListBox>

</Grid>

Now i want to add a "popup-control" to the ListboxItems.

<Popup x:Name="popUpnotifyIcon" AllowsTransparency="True" PopupAnimation="Fade" Placement="Top" PlacementTarget="{Binding ElementName=yahoo}" HorizontalOffset="0" VerticalOffset="20" >

<Viewbox VerticalAlignment="Top" >

<TextBlock Text="dfsdfsdf" />

</Viewbox>

</Popup>

But how do i open the popup when i click a Listboxitem or onmouseover on listboxitem?

Thanks
Rene

Apply Programmatic Custom Sorting Automatic RadGridView/RadTreeListView?

I can sort columns programmatic like the example in documentation using ColumnSortDescriptors
http://www.telerik.com/help/wpf/gridview-sorting-programmatic.html
Also I have a Custom Sorting defined using the GridView Sorting event:
this.radGridView.Sorting += this.radGridView_Sorting;
http://www.telerik.com/help/wpf/gridview-sorting-custom.html
This event only is fired when the user click in the column header it's not fired automatic. How can Sort automatic?

Thank you.

ScheduleView not rendering contents?

Hi guys,

Maybe I am just doing something wrong, but I have lost a lot of time on this already and have no idea what is going on.

I basically have a RadScheduleView Control inside of a Grid on a UserControl. This control is then placed inside of a Grid on a Window. Pretty simple and working perfectly.

My UserControl:

<UserControl x:Class="MonitoringRounds"

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"

mc:Ignorable="d"

d:DesignHeight="600" d:DesignWidth="1000" >

<UserControl.DataContext>

<local:MonitoringRoundsViewModel/>

</UserControl.DataContext>

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="0.05*" />

<RowDefinition />

</Grid.RowDefinitions>

<TextBlock Grid.Row="0">Monitoring Rounds</TextBlock>

<telerik:RadScheduleView Grid.Row="1" Name="radsvMonitoringRounds" Padding="5" MaxHeight="400" MaxWidth="600" AppointmentsSource="{Binding Appointments}" ResourceTypesSource="{Binding ResourcesTypes}">

<telerik:RadScheduleView.ViewDefinitions>

<telerik:MonthViewDefinition />

<telerik:TimelineViewDefinition />

</telerik:RadScheduleView.ViewDefinitions>

</telerik:RadScheduleView>

</Grid>

</UserControl>

My Window:

<Window x:Class="LSpecs"

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

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

<mp:MonitoringPrograms Grid.Row="1" Name="ctrlMonitoringPrograms" Visibility="Hidden"/>

<mr:MonitoringRounds Grid.Row="1" Name="ctrlMonitoringRounds" Visibility="Hidden"/>

</Grid>

</Window>

On the ViewModel behind the window I basically set the visibility of the control to visible when a user clicks on a button. All this works fine.

Also at the moment I am not even trying to add any Appointments. I commented that bit of the code out to eliminate sources of problems. All I want is the control to display properly with the default view and no appointments.

When the control is rendered in run time all the header/menu structure renders fine, but the content area is blank. See attached photo for image of this.

At design time it appears to be fine since it displays the usual "Please set an Appointments Source" message.

Any idea what might be causing this?

Using:
Visual Studio 2010
Targeting .NET Framework 4.0
Windows 7
Telerik.Windows.Controls.ScheduleView vs. 2012.1.326.40

Thanks for your help in advance.

DisplayMemberPath for data binding not working

Hi

I am trying to implement a RadContextMenu and am not seeming to be able to get the DisplayMemberPath to work

The following code does not display the correct label on the menuitem ( the menu items do display)

<telerik:RadButton cal:Message.Attach="Show" BorderBrush="{x:Null}" Background="{x:Null}"

Foreground="Black" FontFamily="Arial" Margin="1,3">

<Grid>

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu ItemsSource="{Binding Items}"
Placement="Right" DisplayMemberPath="DisplayName" / >

</telerik:RadContextMenu.ContextMenu>

<TextBlock VerticalAlignment="Top"

Foreground="Red"

HorizontalAlignment="Right"

Margin="2"

Text="{Binding Status}" />

<StackPanel>

<Image Source="{Binding Icon}" HorizontalAlignment="Center" VerticalAlignment="Center" />

<TextBlock Text="{Binding IconName}" Foreground="White" HorizontalAlignment="Center" />

</StackPanel>

</Grid>

</telerik:RadButton>

But this code does

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu ItemsSource="{Binding Items}" Placement="Right" DisplayMemberPath="DisplayName" >

<telerik:RadContextMenu.ItemTemplate>

<DataTemplate>

<TextBlock Text="{Binding DisplayName}" />

</DataTemplate>

</telerik:RadContextMenu.ItemTemplate>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

I don't want to use the second code I would like to use DisplayMemberPath. I also tried setting ToString() on the buisness object as stated in the documenation (http://www.telerik.com/help/wpf/radcontextmenu-populating-with-data-data-binding-support-overview.html ) But this did not work either.

Does anyone have any idea why this isn't working?

thanks

Murray

Auto column with minimum width

I would like my application GUI to be able to scale with the amount of screen estate available. Using a TileView, seems like the only options to control the column width are:

set ColumnsCount of the TileView, which will cause the tile to resize as the view resizes
set ColumnWidth, which gives each column a fixed width regardless of the size of the view, number of column would change according to the view width.

I quite like the second method, except that it leaves a rather ugly empty void on one side of the TileView.

Is there an option to either:

Cause the tile to stretch similar to when ColumnsCount is set? maybe with a MinimumColumnWidth property... For example, if MinimumColumnWidth=300 and the TileView width is 1100, each of the 3 columns will have the width of 366, and when the TileView has a width of 1200, one more column will appear with width of 300 each.
Evenly space the columns across the whole width of the TileView?
