I have a pie chart which can display up to 20 slices. I have to manually set the color for each slice using a converter.

My biggest issue is that the "object value" being passed into the converter isn't the slice datapoint but is the datacontext of the entire chart. Hence, the hard-coded converter parameter (0, 1, ...) so that I know which dataPoint slice is being converted.

So my xaml looks like this (one style per slice (20) which is BAD for maintaining):

<chartView:PieSeries.SliceStyles>

<Style TargetType="Path">

<Setter Property="Stroke" Value="Gray"/>

<Setter Property="StrokeThickness" Value="1"/>

<Setter Property="Fill" Value="{Binding Converter={StaticResource pieChartSliceToColorConverter}, ConverterParameter=0}"/>

</Style>

<Style TargetType="Path">

<Setter Property="Stroke" Value="Gray"/>

<Setter Property="StrokeThickness" Value="1"/>

<Setter Property="Fill" Value="{Binding Converter={StaticResource pieChartSliceToColorConverter}, ConverterParameter=1}"/>

</Style>

Is there a different style which would eliminate the number of styles I have to maintain? OR a different approach?

Thanks in advance.

AlldayEvent not correct shown - urgent

Dear Telerik Team!

I have a RadScheduleView Control in WeekDayView and want to show some AllDayEvents.

The Problem now is, i have defined a Start and Endtime (this is essential for the control)

<scheduleView:RadScheduleView.ViewDefinitions>

<scheduleView:WeekViewDefinition VisibleDays="7" Title="Wochenansicht - " FirstDayOfWeek="Monday" TimerulerMajorTickStringFormat="{}{0:HH:mm tt}" MajorTickLength="1h" MinorTickLength="30min" MinTimeRulerExtent="1" DayStartTime="06:00" DayEndTime="20:00" ShowAllDayArea="True"/>

</scheduleView:RadScheduleView.ViewDefinitions>

So now, when i have some AllDayEvents in the AppointmentSource they will be shown in complete wrong way
eg.: Allday Event from

08.03.2012 00:00 to 09.03.2012 00:00 will be shown from 07.03 - 08.03 in WeekDayView AllDayArea

when i delete the DayStartTime and DayEndTime Definitions, they will be shown correctly in all Views

is this a known bug ?
I need there some Solution very urgently ...

regards
Rudi

Setting colors in chart view

Hello,
I am using Telerik version 2012.1
What I am trying to do is to build a chart with a single source of data. But the source, the chart type, and the color should be able to be selected in drop down comboboxes. I am having trouble figuring out how to get the color set, don't know if it is because I have a generic chart in the XAML and am setting the series definition in an attached property, or if there is another reason. Below is a sample of my code, let me know if you need more. Thank you,

Eli

<charting:RadChart Grid.Row="3"<br> PaletteBrushesUseSolidColors="True"<br> Name="lineChart"><br> <br> <attached:SeriesMapper.BindingInfo><br> <attached:SeriesBindingInfo DataTable="{Binding DataTable}"

Using button to select next/previous row?

I have a page with a telerik RadGridView and a couple of buttons. I'd like clicking the buttons to select the previous/next rows from the grid. So I'm trying out RadGridViewCommands from the button's Click events:

private void prevButton_Click(object sender, RoutedEventArgs e)

{

var cmd = RadGridViewCommands.MovePrevious as RoutedUICommand;

cmd.Execute(null, myGrid);

}

The various move commands change the focus, but they do not change the selected row.

I've tried MoveUp, followed by SelectCurrentItem, but that doesn't seem to change the selection at all.

Ideas?

Drag & Drop Object From RadTreeview To Textbox

This has probably been asked / answer previously - I couldn't find what I was looking for in my searches, though.

I've got a WPF RadTreeView set up, on WPF 4, with the last 2010 release of the Telerik WPF 4 controls. I've enabled drag & drop within my Treeview, and I am able to correctly drag the selected object (an "Equipment" class) within my treeview.

I've looked at the sample apps that show how to drag an item from a RadTreeview to a Textbox and set up everything correctly, according to the sample. Dragging a basic piece of text, like the example shows, works. However, dragging my Equipment class from the treeview to the Textbox (a standard WPF textbox) does not work. It constantly tells me that the drop is not allowed, even though I've implemented the DragQuery event and set e.QueryResults = true

any tips, tricks, or tutorials to help me get my situation working?

RowStyleSelector and AlternateBackground

Hi!

Maybe its better i start a new Thread for this.
I reffer to this old Topic: http://www.telerik.com/community/forums/wpf/gridview/need-to-change-background-color-of-a-row-based-on-a-condition.aspx

i'am using the StyleSelector to change the background of an GridViewRow in runtime. But i also want to implement an AlternateRowBackground, but - as Tony in the other Topic said - when i set the AlternateRowBackground and AlternationCount-Property in my Grid the StyleSelector doesnt work.
I don't want to create two different Styles for normal Rows and AlternateRows.
Is it possible to set both, RowStyleSelector and AlternateRowBackground or is their a way to implement the AlternateRowBackground in my StyleSelctor? Can i differ if the call comes from the AlternateStyleSelctor or from the RowStyleSelector?

Thank you for your help
Alex

Navigating in Backstage

When I open Backstage in - let say - Word, I can (at once) navigate with the arrow and tabkeys.
I can navigate to buttons like Close and Save and then use the enter-key to execute the methods.
I try to do the same in the RadViews backstage, but it won't work.
How could I get this expected behavior in this backstage?
I tried IsSelectable, IsStapstop and more, but could not get i right.
The keyboardnavigation in Telerik example of the BackStage (Telerik editor) does not work either.

<telerik:RadRibbonBackstage>
<telerik:RadRibbonBackstageItem Header="Modules" IsDefault="true">
<Grid>
....
</Grid>
</telerik:RadRibbonBackstageItem>

<telerik:RadRibbonBackstageItem Header="Setup">
<Grid>
....
</Grid>
</telerik:RadRibbonBackstageItem>

<telerik:RadRibbonBackstageItem CloseOnClick="True" Header="Open" Icon="open.png" Click="OpenClick" />
<telerik:RadRibbonBackstageItem CloseOnClick="True" Header="Edit" Icon="edit.png" Click="EditClick" />
<telerik:RadRibbonBackstageItem CloseOnClick="True" Header="Save" Icon="save.png" Click="SaveClick" />

<telerik:RadRibbonBackstageItem IsGroupSeparator="True"/>

<telerik:RadRibbonBackstageItem CloseOnClick="True" Header="Close" Icon="close.png" Click="CloseClick" />

</telerik:RadRibbonBackstage>

BringDataItemIntoView doesn't work in some circumstances

Hi,

I use Telerik V2010.3.1314.35

I have a TabControl with 2 TabItems, the first one contain a text and the second one contain RadCarousel with 3 images. Of course, the default TabItme is the first one (the one who contain the text). When I star my application, I add my text to my first TabItem and I add my 3 images into my carousel. After adding my images to my carousel, I do the following:

carousel.BringDataItemIntoView(carousel.Items[0]);

After finishing reading my text, I click on my second tab to see the first image of my carousel and it's not there, I have to click on the carousel navigation button to see my images...

xaml:
                                    <telerik:RadCarousel Background="Transparent" ToolTip="{StaticResource ObtainCarouselFullscreen}" Name="SignCtxDocsCarousel" MouseRightButtonDown="SignCtxDocsCarousel_MouseRightButtonDown" VerticalScrollBarVisibility="Hidden" HorizontalScrollBarVisibility="Hidden" IsSynchronizedWithCurrentItem="True">
                                                <telerik:RadCarousel.ItemsPanel>
                                                    <ItemsPanelTemplate>
                                                        <telerik:RadCarouselPanel Path="{StaticResource horizontalPath}"/>
                                                    </ItemsPanelTemplate>
                                                </telerik:RadCarousel.ItemsPanel>
                                            </telerik:RadCarousel>

code:
-------

carousel.Items.Add(img);

if

(carousel.Items.Count > 0)

{

carousel.BringDataItemIntoView(carousel.Items[0]);

}

Thank's

Carousel
