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

"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!

TreeList with multiple instances of the same object

Hi,

We have encountered an issue with binding a hierarchical object model to a RadTreeList when the hierarchy contains multiples references to the same node instance.
For example, if node A contains two children, both node B.

In this scenario it seems the TreeList display and selection become problematic, with tree levels not getting the correct indentation and selecting a node selecting all appearances of the node in the tree (good) but not unselecting them when selection changes.
Unfortunately, Telerik support informed me that this scenario is not supported by the Grid and TreeList controls.

I was wondering if anyone here encountered a similar issue, and if so if there is a simple workaround to allow me to still use the TreeList without having to completely change my existing data structure.

Thanks!

CreateAppointmentWithDialog Animation And Transparency

Hi,

We are using RadScheduleViewCommands.CreateAppointmentWithDialog() to open the dialog when creating an appointment. Is there anyway I can disable the animation of the Dialog as the window is opened and closed?

Also, is there an easy way to remove the transparency of the dialog chrome?

Cheers,
-Brad

Binding button content in GridViewDataColumn

I want to make a column in my RadGridView clickable, such that clicking on a cell in a particular column opens another view with details for that row. I tried adding a button to the column, but I can't get the button to show the text from the actual column. I've got my RadGridView bound to a System.Data.DataTable, and am defining the column as follows:

<telerik:GridViewDataColumn Header="Action" DataMemberBinding="{Binding commandName}" UniqueName="actionButton">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadButton Content="{Binding commandName}" Click="ActionClicked" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

...but the button shows up as a skinny horizontal line with no text. It shows up as expected if I hard code the button content.
