Bind To Image Data Source

I'm attempting to conform to the MVVM paradigm for my project. I'm already binding to a LocationCollection, which I use to plot points for a polygon on the map. This is working fine using the following:

<telerik:InformationLayer Name="informationLayer">

<telerik:MapPolygon Points="{Binding MyPolygon}" />

</telerik:InformationLayer>

I'd like to add additional information in the form of images that are dragged and dropped onto the map. I have no problem manually adding images using the following in the code behind:

RadMap map = (RadMap)e.Options.Destination;

Location dropCursorLocation = Location.GetCoordinates(map, e.Options.RelativeDragPoint);

Image img = new Image { Source = new BitmapImage(new Uri(@"..\Resources\MyImage.png", UriKind.Relative)) };

MapLayer.SetLocation(img, dropCursorLocation);

informationLayer.Items.Add(img);

I'm fine with everything in the view model up until I add the image to the information layer. The MapPolygon typed works well for my polygon, but what should I use for my images? Should I add another type under the InformationLayer section? If so, which type should I use?

Trouble getting started with DragDrop

The example in the documentation for Drag and Drop in RadTreeView indicates that setting IsDragDropEnabled="True" will allow elements to be dragged both into other elements and before/after said elements. However, in my experience I cannot get elements to successfully drag before/after other elements even with the very simple example code (pasted below). What am I missing?

        <telerik:RadTreeView x:Name="radTreeView" Grid.Row="2" IsDragDropEnabled="True" IsDropPreviewLineEnabled="True">
            <telerik:RadTreeViewItem Header="Sport Categories">
                <telerik:RadTreeViewItem Header="Football">
                    <telerik:RadTreeViewItem Header="Futsal"/>
                    <telerik:RadTreeViewItem Header="Soccer"/>
                </telerik:RadTreeViewItem>
                <telerik:RadTreeViewItem Header="Tennis">
                    <telerik:RadTreeViewItem Header="Table Tennis"/>
                </telerik:RadTreeViewItem>
                <telerik:RadTreeViewItem Header="Cycling">
                    <telerik:RadTreeViewItem Header="Road Cycling"/>
                    <telerik:RadTreeViewItem Header="Indoor Cycling"/>
                    <telerik:RadTreeViewItem Header="Mountain Bike"/>
                </telerik:RadTreeViewItem>
            </telerik:RadTreeViewItem>
        </telerik:RadTreeView>

RadSplitButton with ContextMenu in DropDownContent

I've got a form with a RadSplitButton on it. I've set the control's DropDownContent to a RadContextMenu. When I click on the DropDown indicator, the context menu shows. However, when you click on an item in the context menu, the context menu does not close.

How do I make the context menu close once an item in the menu has been clicked? There doesn't seem to be a Close method in the RadContextMenu class, though there are Closing & Closed events.

Also, is there a way that I can change the width of the Drop Down Indicator? There doesn't seem to be a property for it. I'm working on a WPF application with touch screen support that will run in a police car, so everything has to be large for a cop to make effective use while driving. The buttons are rather large & the drop down indicator is down-right puny & easily missed at its current size.

IndexOutOfRangeException when adding new rows

Hi,
when I am using an observable collection of the following class as ItemsSource for the datagrid I get an exception when I add a new Row (via UI, ShowInsertRow is enabled) and the row is commited.

ArgumentOutOfRangeException: "Specified argument was out of the range of valid values. Parameter name: index".
Source: "Telerik.Windows.Data"
Stacktrace: "bei Telerik.Windows.Data.QueryableCollectionView.GetItemAt(Int32 index) in c:\TB\102\WPF_Scrum\Release_WPF_40\Sources\Development\Core\Data\Collections\QueryableCollectionView.cs:Zeile 1766."
File Version of Telerik.Windows.Controls.GridView.dll is 2011.2.712.40.

This happens only when binding a list of ParameterView. ViewModelBase just implements INotifyPropertyChanged.

public class ParameterView : ViewModelBase<ParameterView>

{

private string _name;

public string Name

{

get { return _name; }

set { _name = value; Notify(x => x.Name);}

}

private string _value;

public string Value

{

get { return _value; }

set { _value = value; Notify(x => x.Value); }

}

public ParameterView() : this(string.Empty,string.Empty)

{

}

public ParameterView(string name, string value)

{

Name = name;

Value = value;

}

public override string ToString()

{

return string.Format("Name: {0}, Value: {1}", _name, _value);

}

public bool Equals(ParameterView other)

{

if (ReferenceEquals(null, other)) return false;

if (ReferenceEquals(this, other)) return true;

return Equals(other._name, _name);

}

public override bool Equals(object obj)

{

if (ReferenceEquals(null, obj)) return false;

if (ReferenceEquals(this, obj)) return true;

if (obj.GetType() != typeof(ParameterView)) return false;

return Equals((ParameterView)obj);

}

public override int GetHashCode()

{

unchecked

{

return ((_name != null ? _name.GetHashCode() : 0) * 397) ^ (_value != null ? _value.GetHashCode() : 0);

}

Theme of custom control ComboBox

Hi,

i am having a (maybe?) simple question. In our framework, we have a custom control derivation for each telerik control we use. This works pretty good, but sometimes i have problems to set the theme of the nested controls within such a derivation. One of these problematic cases is the ComboBox. The Vista theme is assigned via Generic.xaml:

<Style TargetType="{x:Type data:ComboBox}" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:VistaTheme, ElementType=telerik:RadComboBox}}">

<Setter Property="Height" Value="23"></Setter>

<Setter Property="ItemContainerStyle">

<Setter.Value>

<Style TargetType="{x:Type telerik:RadComboBoxItem}" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:VistaTheme, ElementType=telerik:RadComboBoxItem}}">

</Style>

</Setter.Value>

</Setter>

</Style>

In the code file, we force the usage of the new theme:

Shared Sub New()

' Connect new template

DefaultStyleKeyProperty.OverrideMetadata(GetType(ComboBox), New FrameworkPropertyMetadata(GetType(ComboBox)))

End Sub

Protected Overrides Sub OnInitialized(ByVal e As System.EventArgs)

' Call base class method

MyBase.OnInitialized(e)

' Ensure template

Me.DefaultStyleKey = GetType(ComboBox)

End Sub

This works good. The ComboBox and the items are using the Vista theme. But now, i want the Box to be editable. The TextBox, the Button and the ScrollViewer are still using the default theme. How can i archive, that the named controls use the Vista theme? I want to define that in the Generic.xaml.

I hope you can help me. Styling and templating are not my favourite tasks ;-)

Greeting from germany, Carsten

File load error referencing new internal build 2011.2.808.40

When going into design mode of my ApplicationResource.xaml file, I see the following error come up. Everything seems to compile fine but my outlinging expansion and intellisense no longer works in the xaml file. Wondering if this has to do with the load error. Here is the stack trace...

System.NotSupportedException

An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.
