Hello,

I use the following code, I created a pie chart that appears with label displayed in spider mode (SpiderModeEnabled = true). However, did not displayed label of "Foo". (image1.jpg)

MainWindow.xaml

<Window x:Class="Test.MainWindow"

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

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

Title="MainWindow"

Height="250"

Width="495"

xmlns:TelerikChart="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting"

xmlns:TelerikCharting="clr-namespace:Telerik.Windows.Controls.Charting;assembly=Telerik.Windows.Controls.Charting">

<Grid>

<TelerikChart:RadChart x:Name="m_RadChart" />

</Grid>

</Window>

MainWindow.xaml.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

using Telerik.Windows.Controls.Charting;

using Telerik.Windows.Controls;

namespace Test

{

// Data model.

public class ChartRecord

{

public string Legend { get; set; }

public int Value { get; set; }

}

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

// Create data source.

List<ChartRecord> source = new List<ChartRecord>();

source.Add(new ChartRecord() { Legend = "Foo", Value = 50 });

source.Add(new ChartRecord() { Legend = "Bar", Value = 30 });

source.Add(new ChartRecord() { Legend = "Baz", Value = 20 });

m_RadChart.ItemsSource = source;

m_RadChart.DefaultView.ChartArea.SmartLabelsEnabled = true;

PieSeriesDefinition definition = new PieSeriesDefinition();

// Setup label settings.

RadialLabelSettings labelSettings = new RadialLabelSettings();

labelSettings.SpiderModeEnabled = true;

labelSettings.ShowConnectors = true;

definition.LabelSettings = labelSettings;

// Setup mappings.

SeriesMapping seriesMapping = new SeriesMapping();

seriesMapping.SeriesDefinition = definition;

seriesMapping.ItemMappings.Add(new ItemMapping("Value", DataPointMember.YValue));

seriesMapping.ItemMappings.Add(new ItemMapping("Legend", DataPointMember.XCategory));

m_RadChart.SeriesMappings.Add(seriesMapping);

}

In addition, connecter disappeared when after making resize to small window until a pie chart disappears, restore to the original size. (image2.jpg)

Do you have problem solution?

Thanks,

Sort/filter on a column of type RadGridViewComboBox

Hi,

I've a column which is a RadGridViewComboBox. Before it was only a normal text column and I was able to filter /sort on it, but now since it has to be editable, I had to replace this by a RadGridViewComboBox, but now the little funnel isn't displayed anymore.

Why this?

Here is how I made it:

<telerik:GridViewComboBoxColumn Header="Product" Width="2*" DataMemberBinding="{Binding Product}" DisplayMemberPath="FullDescription" ItemsSource="{Binding Products}"/>

Thank you!

Sorting state 'None'

Hi,

I want to handle the sorting state 'None' so as to sort the records in ascending order of first column. I have added following code to implement this

private void playersGrid_Sorting(object sender, GridViewSortingEventArgs e)

{

if (e.NewSortingState == SortingState.None)

{

this.playersGrid.SortDescriptors.Clear();

SortDescriptor descriptor = new SortDescriptor();

descriptor.Member = "Name";

descriptor.SortDirection = System.ComponentModel.ListSortDirection.Ascending;

//ColumnSortDescriptor csd = new ColumnSortDescriptor();

//Telerik.Windows.Controls.GridView.ColumnSortDescriptor csd = new Telerik.Windows.Controls.GridView.ColumnSortDescriptor();

//csd.Column = this.playersGrid.Columns[0];

//csd.SortDirection = System.ComponentModel.ListSortDirection.Ascending;

this.playersGrid.SortDescriptors.Add(descriptor);

}

I have tried to use sort descriptor and ColumnSortDescriptor but none of these worked for me. Please suggest how can i acomplish this behaviour.

left aligned numeric input

Hello,

is it possible to have a left aligned RadMaskedNumericInput field?

Setting the HorizontalContentAlignment to left will show a left aligned value in view mode, but while editing there is a margin on the left side of the value. i tried to set the TextBoxStyle, but with no success.

i know that numeric field typically aligned right, but sometimes there are exceptions ;)

[Solved] Getting an error when upgrading to 2011.3.1116.0

I got a message today, when I got into VS 2010, that there was an upgrade to the Telerik WPF toolkit to 2011.3.1116.0. However, I'm now having problems getting it installed. I think it may be because I hadn't launched VS 2010 as an administrator; I ran it as a regular user. When I did, it complained that it couldn't uninstall something (the preivous version, I believe). Now, every time I get into VS 2010 I get a message saying that VS Extension Manager sees an update from version 2011.2.915.0 to 2011.3.1116.0. When I tell it to run the upgrade, it now fails with the error message:

"Microsoft Visual Studio
The extension could not be installed because the folllwing error occurred:
Telerik WPF VSExtensions is already installed"

I'm running this on a Windows 7 Ultimate machine, 32-bit.

Continuous RadScheduleView

Are there any examples using the RadScheduleView in a continuous manner in the Timeline view. I'd like to hide the date range selection and just allow the user to scroll forever. First thought is I could respond to an event when a new day is scrolled into view and just expand the underlying window. Is this possible? Is there already an example of this somewhere?

Thanks!

Filtering not working?

We seem to have a problem getting filtering working correctly.

The behaviour we are seeing in our application is demonstrable in the demo.

Steps to reproduce:-
1. Run WPF Demos
2. Select TreeListView from All Controls
3. In the Name column select the filter
4. Set “Show rows with a value that” to Starts with
5. Type in “set” and then apply the filter, all works as expected
6. Clear the filter
7. Type in “get” and then apply the filter. Nothing happens; the previous filter based on “set” is applied.

To summarise we seem to be able to set a filter only once, after that you need to close the app to clear the filer.

Apologies if this has been reported before and been fixed in a later build than we are using (Q2 2011 SP1 – 2011.2.920.35)

Regards

John
