Binding problem with nested childtabledefinitions

// 1) Classes that define each of the levels (NodeItem being the base class)

public class NodeItem

{

public string Name { get; set; }

public string Path { get; set; }

}

public class SourceDirectoryItem : NodeItem

{

public SourceDirectoryItem()

{

this.Children = new ObservableCollection<NodeItem>();

}

public ObservableCollection<NodeItem> Children { get; set; }

}

public class SourceFileItem : NodeItem

{

public SourceFileItem()

{

this.Functions = new ObservableCollection<NodeItem>();

}

public ObservableCollection<NodeItem> Functions { get; set; }

}

public class FunctionItem : NodeItem

{

}

// 2) XAML

<telerik:RadTreeListView

AutoGenerateColumns="False"

ItemsSource="{Binding Nodes}">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}">

<telerik:TreeListViewTableDefinition.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}">

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Functions}" />

</telerik:TreeListViewTableDefinition>

</telerik:TreeListViewTableDefinition.ChildTableDefinitions>

</telerik:TreeListViewTableDefinition>

</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="NAME">

</telerik:GridViewDataColumn>

</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

// 3) In the VM there is nothing special, this is how I populate the nodes:

private void InitNodes()

{

SourceDirectoryItem root = new SourceDirectoryItem() { Name = "c:\\", Path = Name };

SourceDirectoryItem firstLevel = new SourceDirectoryItem() { Name = "c:\\folder1", Path = Name };

SourceDirectoryItem secondLevel01 = new SourceDirectoryItem() { Name = "c:\\folder1\\temp", Path = Name };

SourceDirectoryItem secondLevel02 = new SourceDirectoryItem() { Name = "c:\\folder1\\programfiles", Path = Name };

firstLevel.Children.Add(secondLevel01);

firstLevel.Children.Add(secondLevel02);

root.Children.Add(firstLevel);

SourceFileItem sf = new SourceFileItem();

sf.Name = "foo.cs";

sf.Path = "c:\\temp";

sf.Functions.Add(new FunctionItem() { Name = "Method001" });

sf.Functions.Add(new FunctionItem() { Name = "Method002" });

sf.Functions.Add(new FunctionItem() { Name = "Method003" });

secondLevel01.Children.Add(sf);

SourceFileItem sf1 = new SourceFileItem();

sf1.Name = "bar.cs";

sf1.Path = "c:\\programfiles";

sf1.Functions.Add(new FunctionItem() { Name = "AnotherMethod" });

secondLevel02.Children.Add(sf1);

this.Nodes.Add(root);

}

private ObservableCollection<NodeItem> nodes;

public ObservableCollection<NodeItem> Nodes

{

get

{

return this.nodes;

}

set

{

this.nodes = value;

this.OnPropertyChanged("Nodes");

}

So my issue is that if I leave the binding for Functions in the XAML I get what you can see in pic 1 (issue.jpg) the third level directory entries are not expandable; if I remove that binding then I get the hierarchy working, of course up until the source file level (no_functions_binding.jpg).

Any idea what could be going on?

Thanks,
Jose

MouseMove event doesn't get fired

internal WndMain()

{

InitializeComponent()

this.GridViewLocalizations.MouseMove += new MouseEventHandler(GridViewLocalizations_MouseMove);

}

void GridViewLocalizations_MouseMove(object sender, MouseEventArgs e)

{

}





"GridViewLocalizations_MouseMove" does not get called on moving the mouse over the GridView. Why?

How can I trap MouseMove events on a GridView?



And why can't I write outside of this code block anyway?? Man, Telerik sometimes...

Add other controls in TileView

hi,
Is there a way to add controls that are not text inside the expanded Tile?
I want to create a navigation system, where the application menu items would be available in minimized form. and then when they expand the tile, a lis of sub items would show up. Like for example, I want to include an expander inside one tile. And some other control like bunch of RadSplitButtons in other.
A working example would be great?
thanks
Sri

ScrollIntoView still not working

This issue is similar to this issue.

We're using the RadScheduleView only with MonthViewDefinition.
There's room on the screen for 4 weeks only (and Oct. 2011, for example, takes 6 weeks: 25/09/2011 is the first week, 30/10/11 is the last).

When the view is scrolled to its top (Showing first 4 weeks), and an appointment is being selected (from an external list, updated via binding of SelectedAppointment) that starts on the 5'th week, ScrollIntoView method does not scroll to the proper week, and the appointment, although being selected, stays off the view.

We're using this attached behavior:

public static class RadSchedule

{

public static bool GetEnsureVisibilityOfSelectedAppointments(DependencyObject obj)

{

return (bool)obj.GetValue(EnsureVisibilityOfSelectedAppointmentsProperty);

}

public static void SetEnsureVisibilityOfSelectedAppointments(DependencyObject obj, bool value)

{

obj.SetValue(EnsureVisibilityOfSelectedAppointmentsProperty, value);

}

public static readonly DependencyProperty EnsureVisibilityOfSelectedAppointmentsProperty =

DependencyProperty.RegisterAttached("EnsureVisibilityOfSelectedAppointments", typeof(bool), typeof(RadSchedule), new UIPropertyMetadata(false, EnsureVisibilityChanged));

private static void EnsureVisibilityChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

{

if (d == null)

{

throw new ArgumentNullException("d");

}

var view = d as RadScheduleView;

if (view == null)

{

throw new NotSupportedException("This attached behavior can only be set on a Telerik RadScheduleView.");

}

var shouldEnsureVisibility = (bool)e.NewValue;

if (shouldEnsureVisibility)

{

view.AppointmentSelectionChanged += view_AppointmentSelectionChanged;

}

else

{

view.AppointmentSelectionChanged -= view_AppointmentSelectionChanged;

}

static void view_AppointmentSelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)

{

if (sender == null)

{

throw new ArgumentNullException("sender");

}

var view = sender as RadScheduleView;

if (view == null)

{

throw new NotSupportedException("This attached behavior can only be set on a Telerik RadScheduleView.");

}

if (view.SelectedAppointment == null)

{

return;

}

view.ScrollIntoView(view.SelectedAppointment, true);

// According to http://www.telerik.com/community/forums/wpf/scheduleview/scrollntoview-not-working.aspx,

// this should have solved this issue:

view.CurrentDate = view.SelectedAppointment.Start.Date;

}

What am I missing?

Thanks in advance,
Idan Felix.

What's the rectangle above the drag cue when dragging?

When I'm dragging an item, I update the drag cue text, which is correct, but just above it, and to the left of the mouse pointer, is a small, yellow/orange rectangle/box.

What is this and how do I make it go away? Thanks.

Refresh/Update RadScheduleview user interface

Hi,
I want to force the radscheduleview to refresh. Because when I call the ScrollIntoView(slot,true), it is not reflected in the scheduleview. But when I change the date from the navigation panel the UI is refreshed and scrolls to the specified slot. So I just want to force the Scheduleview to update its UI elements. Please help..

With Regards,
Jeyakumar

Binding by RtfDataProvider

Hello!
I am trying to load a .rtf document in the RadRichTextBox using bindings in XAML.
Here is my XAML:

<UserControl.DataContext>

<DutyRegulations:DutyRegulationsViewModel/>

</UserControl.DataContext>

<UserControl.Resources>

<DataTemplate x:Key="TabContentTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<telerik:RadRichTextBox x:Name="radRichTextBox" IsReadOnly="True" Grid.Column="0" Width="500" Height="500"/>

<Rtf:RtfDataProvider Rtf="{Binding FileSource}" RichTextBox="{Binding ElementName=radRichTextBox}"/>

</Grid>

</DataTemplate>

</UserControl.Resources>

<Grid>

<telerik:RadTabControl HorizontalAlignment="Stretch" Name="radTabControl" VerticalAlignment="Stretch" ItemsSource="{Binding Path=StaffDutyRegulations}" DisplayMemberPath="Staff.Name" ContentTemplate="{StaticResource TabContentTemplate}"/>

</Grid>

What type should be the object that is bound to the "Rtf" property of RtfDataProvider? Can I pass an array of bytes? Can I do it without any code-behind? I can see in the output that my code always throws an exception : "A first chance exception of type 'System.NullReferenceException' occurred in Telerik.Windows.Documents.dll". Thank you in advance.

Sincerely yours,
Mike.

RowDetails collapse after 10 seconds

Hi,

I have implemented RadGridView with row details. The RowDetailsVisibilityMode="VisibleWhenSelected" , when I expand a row, the details is shown, but it collapses after 10 seconds.

Is there a setting to control this behavior?
