Cell/Row selection when mouse right click

Hello,
I'm using Q1 2010 RadGridView in an application where I have a context menu that displays options based on the cell value.

It works perfectly when the user clicks on the cell (CurrentCell property is being loaded) and then right click on it to get the context menu. However, I'd like to provide a behavior like excel in which, when the user rightclicks on any cell, it gets selected and the corresponding context menu will consider the actual cell value.
I couldn't find any property like "SelectCellOnMouseRightClick" or workaround that could help me achieve this. Is there a way I can have this behavior in my RadGridView?

My SelectionMode="Extended", as there are other operation that require multiple row selection.

Thanks in advance

Vertical scrolling on scroll wheel

Hello, is there any way to scroll the RadTimeline vertically with the scroll wheel?

Ideally I'd like to have the zoom behaviour be restricted to the horizontal scrollbar (user can drag the horizontal bar's edges to zoom in and out etc), but I'd like to bind the vertical scroll position to the scroll wheel. I've achieved this with a RadChart using the PanAndZoomBehavior, but there is no equivalent for the Timeline.

Is there at least a way to programatically scroll the TimelineScrollBar from behind code when I capture the mouse wheel event?

Problem when using ResourceTypesSource and SpecialSlotStyleSelector

Hi,

When I use ResourceTypeSource and SpecialSlotStyleSelctor I dont get the style for the HighlightItem. When I remove the ResourceTypeSource I get the style returned by the specialSlotStyleSelector. I dont know where I made mistake.. Plz Help...

Here is my ScheduleView

<sv:RadScheduleView x:Name="Scheduler" AppointmentsSource="{Binding Appointments}" Loaded="Scheduler_Loaded"

MouseLeftButtonUp="Scheduler_MouseLeftButtonUp" ShowDialog="Scheduler_ShowDialog"

ResourceTypesSource="{Binding ResourceTypes}" AppointmentCreating="Scheduler_AppointmentCreating" >

<sv:RadScheduleView.ViewDefinitions>

<sv:DayViewDefinition ShowAllDayArea="True" MajorTickLength="1h" MinorTickLength="30min" />

<sv:WeekViewDefinition ShowAllDayArea="True" MajorTickLength="1h" MinorTickLength="30min" />

<sv:MonthViewDefinition />

</sv:RadScheduleView.ViewDefinitions>

<sv:RadScheduleView.GroupDescriptionsSource>

<sv:GroupDescriptionCollection>

<sv:DateGroupDescription />

<sv:ResourceGroupDescription ResourceType="Speaker" />

</sv:GroupDescriptionCollection>

</sv:RadScheduleView.GroupDescriptionsSource>

</sv:RadScheduleView>

And the SpecialSlotStyleSelector...

class SpecialSlotStyleSelector:ScheduleViewStyleSelector

{

private Style nonworkingHourStyle;

public Style NonworkingHourStyle

{

get

{

return this.nonworkingHourStyle;

}

set

{

this.nonworkingHourStyle = value;

}

public override Style SelectStyle(object item, DependencyObject container, ViewDefinitionBase activeViewDefinition)

{

return this.NonworkingHourStyle;

}

And here is the style..

<s:SpecialSlotStyleSelector x:Key="SpecialSlotStyleSelector">

<s:SpecialSlotStyleSelector.NonworkingHourStyle>

<Style TargetType="{x:Type sv:HighlightItem}">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate>

<Border Background="LightGray" Opacity="0.8" />

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

Modify color of PointSeries in code?

I am charting multiple PointSeries. I am creating each PointSeries in code. How do you control the color of each PointSeries?

Code:

var chartViewModel = Grid.DataContext as ChartViewModel;

var pointSeries = new PointSeries

{

ItemsSource = chartViewModel.DataPoints,

CategoryBinding = new PropertyNameDataPointBinding("DateTime"),

ValueBinding = new PropertyNameDataPointBinding("Point"),

PointSize = new Size(3, 3)

};

Chart.Series.Add(pointSeries);

XAML:

<telerik:RadCartesianChart x:Name="Chart">

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis LineThickness="1"

MajorTickLength="5"

TickThickness="1"/>

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:DateTimeCategoricalAxis DateTimeComponent="Minute"

LabelFormat="M/d H:mm"

LineThickness="1"

MajorTickInterval="60"

MajorTickLength="5"

TickThickness="1"/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid MajorLinesVisibility="XY" />

</telerik:RadCartesianChart.Grid>

</telerik:RadCartesianChart>

Crash on resize GanttView

Hello,

I'm intensively testing RadGantt on different machines. I noticed that the component crashes on every resize on 1 specific machine.
The machine is an Asus N56VM with win 7 installed.

When starting the machine in safe mode, there is no crash. After some research I noticed it is the graphics card (Intel HD Graphics 4000) that causes the crash.

Is this something new to you guys? If not, could you provide me with a solution?

All other machines work like a charm, even a 5-6 year old one with Win XP.

Kind Regards

Inherited/Custom DatePicker

I want to extend RadDatePicker. I've created this class:

public class CustomRadDatePicker : RadDatePicker

{

// no code yet

}

As you can see there is absolutely no code yet in this class but when adding CustomRadDatePicker instead of RadDatePicker in XAML there is no control displayed at design time and runtime. I've extended many other of your controls and there were no Problems so can you please tell me what's wrong here? I need to extend RadDatePicker.
