How to know when the RadMap is finished rendering

I'm trying to render the RadMap as an image at the request of a user via a command. I need the command to be disabled until the RadMap is finished rendering otherwise it is possible for the rendered image to be missing parts of the map. How do I know when the RadMap is finished rendering?

TextBox with Outlook "To" field functionality

Hi.

I need to create a control that behaves like the "To" field in Outlook. In short words it´s a TextBox with AutoComplete and the items that have been added by the AutoComplete are styled differently from text entered manually.

Another important thing is how backspace works, Backspace on a manually entered text will remove a char. Backspace on an item added by AutoComplete will remove the whole item.

Do you have any tips on how this can be achieved in WPF with the use of the Telerik library?

Best regards
Øystein

When I hover over a RadComboBox and scroll the mouse wheel the selecteditem changes. I get this behavior with a ComboBox only when the control has focus. I want the RadComboBox to work the same. Is there anyway for me to disable that on the RadComboBox?

Thanks,

Using ItemsSource and DataTemplate

I have a drop down button that contains a context menu as the drop down content. I'm binding my ItemsSource of the ContextMenu to a collection of Items on my view model. Because it's inside a DropDownButton, I'm handling the ItemClick event to close the drop down. But I'd like to also use a command on my view model and pass the bound object as the parameter.
Right now, I'm using a DataTemplate, but then I get a menuItem inside a menuItem.
Here is my button and context menu code.

<telerik:RadDropDownButton Content="Assign" DockPanel.Dock="Right" Margin="3" Name="RolesMenu">

<telerik:RadDropDownButton.DropDownContent>

<telerik:RadContextMenu ItemsSource="{Binding RolesList}" ItemClick="RolesMenu_ItemClick">

<telerik:RadContextMenu.ItemTemplate>

<DataTemplate>

<telerik:RadMenuItem Header="{Binding RoleName}" Command="{Binding AssignRole}" CommandParameter="{Binding DataContext, RelativeSource={RelativeSource Mode=Self}}" />

</DataTemplate>

</telerik:RadContextMenu.ItemTemplate>

</telerik:RadContextMenu>

</telerik:RadDropDownButton.DropDownContent>

</telerik:RadDropDownButton>

How can I do the same thing as above without getting a menuItem inside a MenuItem?

public XAxisTest()

{

InitializeComponent();

Context = new Context();

DataContext = this;

}

public Context Context { get; set; }

}

public class Context

{

public Context()

{

Charts = new ObservableCollection<ChartDataHolder> { new ChartDataHolder(1), new ChartDataHolder(100) };

}

public ChartDataHolder FirstData

{

get

{

return Charts[0];

}

public ObservableCollection<ChartDataHolder> Charts { get; private set; }

}

public class ChartDataHolder

{

public ChartDataHolder(double delta)

{

ChartData = new ObservableCollection<ChartDataItem>();

for (int i = 0; i < 20; i++)

{

ChartData.Add(new ChartDataItem() { ValueX = DateTime.Now.Second + i, ValueY = DateTime.Now.Second * delta + i });

}

public ObservableCollection<ChartDataItem> ChartData { get; private set; }

}

public class ChartDataItem
