export to excel problem in WPF : GridView

Hi,
I export to Excel and it work fine, but when one of the rows contains a xml value I get an error when opening up the exported file in Excel:

"Problems during load:
Problems came up in the following areas during load:
Table - file cannot be opened because of errors."

The error log is like this:
XML PARSE ERROR: Malformed or illegal processing instruction
Error occurs at or below this element stack:
    <ss:Workbook>
     <ss:Worksheet>
      <ss:Table>
       <ss:Row>
        <ss:Cell>
         <ss:Data>

I guess Excel gets confused when there's two xml tags in the file?
I use 'xml' extension and ExportFormat.ExcelML

I read another thread about export where there was a problem regarding german umlaut letters.
The solution was to use encoding

byte[] buffer = Encoding.UTF8.GetBytes("<meta charset=\"utf-8\">");
stream.Write(buffer, 0, buffer.Length);

I there a similar way to fix this? to somehow format/encode the xml value so that the file can be exported....

Disable resizing column while editing cell

Hi!

I wish to disable column resizing (for example, DataGridViewColumn) while editing cell in standard manner. When I type too long text in cell then column width is growing up that is unnecessary for me. I tried to set column width in design time to "Auto" or to particular width - no effect at all. Can anybody help me?

How Can I Grouping by tags a RadGridView

I have this class

public class myObject

{

public String Name { get; set; }

public List<String> Tags{get;set;}

}

this ViewModel

public class ViewModelMainWindow:ViewModel

{

System.ComponentModel.ICollectionView m_myListOfObject;

public ICollectionView MyListOfObject

{

get { return m_myListOfObject; }

set { m_myListOfObject = value; }

}

I initialize my App

public partial class App : Application

{

MainWindow m_ViewMainWindow;

ViewModelMainWindow m_ViewModelMainWindows;

List<myObject> m_myListOfObject;

protected override void OnStartup(StartupEventArgs e)

{

Init();

m_ViewMainWindow.Show();

}

void Init()

{

m_ViewMainWindow = new MainWindow();

m_ViewModelMainWindows = new ViewModelMainWindow();

PropertyGroupDescription groupDescriptionPorte = new PropertyGroupDescription("Tags");

m_myListOfObject = new List<myObject>();

m_myListOfObject.Add(new myObject());

m_myListOfObject.Last().Name = "Element 1";

m_myListOfObject.Last().Tags = new List<string>();

m_myListOfObject.Last().Tags.Add("Tag 1");

m_myListOfObject.Last().Tags.Add("Tag 2");

m_myListOfObject.Add(new myObject());

m_myListOfObject.Last().Name = "Element 2";

m_myListOfObject.Last().Tags = new List<string>();

m_myListOfObject.Last().Tags.Add("Tag 1");

m_myListOfObject.Last().Tags.Add("Tag 3");

m_myListOfObject.Add(new myObject());

m_myListOfObject.Last().Name = "Element 3";

m_myListOfObject.Last().Tags = new List<string>();

m_myListOfObject.Last().Tags.Add("Tag 2");

m_myListOfObject.Last().Tags.Add("Tag 4");

m_ViewModelMainWindows.MyListOfObject = CollectionViewSource.GetDefaultView(m_myListOfObject);

m_ViewModelMainWindows.MyListOfObject.GroupDescriptions.Add(groupDescriptionPorte);

m_ViewMainWindow.DataContext = m_ViewModelMainWindows;

}

How can I view the groups by tags "Tag 1", "Tag 2", "Tag 3", "Tag 4" in a RadGridView?
In m_ViewModelMainWindows.MyListOfObject I have 4 groups, but in RadGridView of MainWindow I have 3 groups of list.

The MainWindow.xaml is

<Window

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

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

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Class="grouping_by_tags.MainWindow"

Title="MainWindow" Height="350" Width="525">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="137*"/>

<RowDefinition Height="183*"/>

</Grid.RowDefinitions>

<telerik:RadGridView HorizontalAlignment="Left" Height="320" VerticalAlignment="Top" Width="517" ItemsSource="{Binding MyListOfObject}" Grid.RowSpan="2"/>

</Grid>

</Window>

Best regards

Riccardo

PlotArea - Margin not equivalent

Hi,

I got some axis on the left and right side and it turns out the left margin of the plot area is a few pixels thick when the right margin is not.
Left side: https://dl.dropboxusercontent.com/u/55589036/Pictures/Screenshots/20150210105316.png
Right side: https://dl.dropboxusercontent.com/u/55589036/Pictures/Screenshots/20150210105510.png

How can I add the same margin to the right side as it appears on the left side?

Limit connections between shapes

Is there a way to limit which shapes can be connected?

For example, my diagram has three shapes, Ellipse, Hexagon and Star. Ellipse can be connected to Star and Hexagon can be connected to Star; however, Ellipse can never be connected to a Hexagon.
