Keyboard Navigation for Grid and other controls

I am starting work on making our WPF application keyboard accessible, starting with the grids.

I am having trouble finding info on:
1. What is already available for keyboard navigation for GridView and other Telerik controls
2. What I need to code myself
3. Samples / tips on best practices for this

I have found a sample project (Silverlight) but it only provides a very small supset of the requirements.

Any help appreciated...

Add items to a VirtualQueryableCollectionView

I'm working on a wpf project with large datasets.
I've searched for simple examples on using the VirtualQueryableCollectionView with a RadGridView and followed you example at

http://www.telerik.com/help/wpf/using-data-virtualization.html

Now I've tried severaly methods of adding an item in the grid, but without success. If I bind to a standard CollectionView I have no problems though. Editing existing items poses no problems either.

Do you have a working example where you bind the RadGridView to the VirtualQueryableCollectionView and support adding items in the gridview?

Thanks in advance

Labels on the X axis angularly

Setting labels on the X axis angularly (45 degrees) causes the resize of the axis - it becomes too big.
See attached files.

"Border" of the last selected item

Hello,
I have a RadToolBar with buttons on it. When I click on a button a "border" appears around it. After focus is moved to another control the border still remains on the button.

Is it possible to remove that "border" after toolbar loses focus?

Multi-Book Multi-Touch

Hi TT,
I'm making an application to surface in wpf.
For this application, I need to instantiate more than one book and there are no problems.
But if I try to browse through more than one book at the same time (such as surface allows), it only works one at a time. To be precise, only works that you are flipping through the book and nothing else.
Is there a way to solve this problem?

Thank you for helping
Chianco

Access to scheduleView in appointment editor view model

Hi,

i have implemented a custom appointment editor dialog using the dialog host factory. Now i need access to the scheduleview instance from within the viewmodel of my appointment editor dialog. Especially i need to know from which viewdefinition (month, day, week...) the dialog was started so i can set the start and end dates appropriately.
I saw that the original appointmentdialogviewmodel (from which i have an instance in my custom editor viewmodel) has a property called DialogHost and this property has another property "ScheduleView" which is in fact the instance i need access to. However the "DialogHost" property on the appointmentDialogViewModel is protected so i can't access it within my viewmodel.
How can i get access to the scheduleview instance from within my custom view model?

best regards

matthias

Data outside of maximum vertical axis plots to top-left corner

Hi,

I've found that plotting data with where the Y value is above the maximum vertical axis plots somewhere to the top-left corner of component (outside of the visible component). Here's an example:

XAML:

<Window

x:Class="RadChartViewSimpleTest"

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

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

xmlns:chart="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Chart"

xmlns:chartView="clr-namespace:Telerik.Windows.Controls.ChartView;assembly=Telerik.Windows.Controls.Chart"

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

Width="300"

Height="300">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<DataGrid

ItemsSource="{Binding}" />

<chart:RadCartesianChart

Grid.Column="1">

<chart:RadCartesianChart.HorizontalAxis>

<chartView:LinearAxis />

</chart:RadCartesianChart.HorizontalAxis>

<chart:RadCartesianChart.VerticalAxis>

<chartView:LinearAxis

Maximum="100" />

</chart:RadCartesianChart.VerticalAxis>

<chart:RadCartesianChart.Series>

<chartView:ScatterLineSeries

x:Name="ScatterLineSeries1"

ItemsSource="{Binding}" />

</chart:RadCartesianChart.Series>

</chart:RadCartesianChart>

</Grid>

</Window>

VB:

Imports Telerik.Windows.Controls

Imports Telerik.Windows.Controls.ChartView

Public Class RadChartViewSimpleTest

Public Sub New()

InitializeComponent()

Dim Points As New List(Of Point)

For i As Integer = 0 To 150 Step 5

Points.Add(New Point(i, i))

Next

For i As Integer = 0 To 150 Step 5

Points.Add(New Point(155 + i, i))

Next

Me.DataContext = Points

Dim genericBinding As New GenericDataPointBinding(Of Point, Double)

genericBinding.ValueSelector = Function(t As Point) t.X

ScatterLineSeries1.XValueBinding = genericBinding

genericBinding = New GenericDataPointBinding(Of Point, Double)

genericBinding.ValueSelector = Function(t As Point) t.Y

ScatterLineSeries1.YValueBinding = genericBinding

End Sub

End Class

The chart has a maximum vertical (linear) axis of 100, however the data generated in code-behind plots from 0 to 150. The resulting graph ends up quite funky (and incorrect).

I've also noted that irrespective of what I set for "RangeExtendDirection" in the vertical linear axis, the maximum range is never extended and the minimum range is always extended, ie. RangeExtendDirection is always acts as Negative irrespective of the value I set it to.

Kind regards,
Dave.

ps. Love the new performance of the ChartView component!
