Remove a column permanently from the HeaderMenu context menu.

With GridViewHeaderMenu.IsEnabled="true" settings, I always get all the columns in the context-menu at right click of header for hide/show. But I would want, not to display a column that I am keeping visible=false always. How to do that. Your help would be greatly appreciated.

MapLine within different UserControl

Hi,

I was wondering if it were possible to place MapLine controls into a different UserControl.
In other words, I want to separate the radMap control from the MapLine controls by using a UserControl.
So I would have a parent containing the map and a child containing the lines:

ParentUserControl
<InformationLayer>
<Views:ChildUserControl/>
<InformationLayer/>

ChildUserControl
<MapLine Point="0,0" Point2="10,10"/>

Unfortunately, it doesn't seem to work at all... Any ideas what might be the best solution?

Thank you,
Alexis

Drag drop - html table to Microsoft Word (WPF)

Hi,

I am trying to implement dragging & dropping HTML table to Microsoft word document.

It is a WPF application where I am dragging a RadListBox item to word and if I am setting data objects type to "Text" then plain text is getting dropped in MS word document.
var payload = DragDropPayloadManager.GeneratePayload(null);
payload.SetData("Text", "I am a plain text");

But my requirement is to drag and drop formatted text (with background, border, different font color).

Please advise.

[Solved] Background Zoom (and Pan)

Hi. I'm loving these new controls, but I have a question. Is there a way to make the background of the RadDiagram Zoom and Pan along with the shapes? Right now, the content of the diagram is working just fine, however my background remains at the same zoom level. I'm assuming that is default behavior, but I would like to have the background image zoom as well. Is that possible?

Getting Started with DragDrop

Trying to make my first DragDrop among RadListBox working but not sure what I am missing - but I am sure that I am missing something. I just have two list boxes - one bound to available friends (from where the drag is initiated) and the other one bound to selected friends where the friends are dropped. But at this point, it just shows up as being dragged from the originating Radlistbox - but nothing comes in the other radlistbox. Pls help.
Here is my XAML and ViewModel. How does this work? Whenever I drop a friend - then ViewModel setter is also not called. So - how actually the OtherRadListBox gets bound to the dropped values.

<Window.DataContext>

<local:MainViewModel />

</Window.DataContext>

<Window.Resources>

<Style x:Key="DraggableListBoxItem" TargetType="telerik:RadListBoxItem">

<Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True" />

</Style>

</Window.Resources>

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<telerik:RadListBox ItemContainerStyle="{StaticResource DraggableListBoxItem}"

AllowDrop="True"

Grid.Column="0" ItemsSource="{Binding AvailableDropZones}" DisplayMemberPath="Name">

<telerik:RadListBox.DragDropBehavior>

<telerik:ListBoxDragDropBehavior />

</telerik:RadListBox.DragDropBehavior>

</telerik:RadListBox>

<telerik:RadListBox ItemsSource="{Binding SelectedDropZones}" Grid.Column="1" AllowDrop="True" DisplayMemberPath="Id">

<telerik:RadListBox.DragDropBehavior>

<telerik:ListBoxDragDropBehavior />

</telerik:RadListBox.DragDropBehavior>

</telerik:RadListBox>

</

Grid>



public class MainViewModel :ViewModelBase

{

public MainViewModel()

{

ObservableCollection<Friend> list = new ObservableCollection<Friend>();

list.Add(new Friend() { Id = 1, Name = "Andy" });

list.Add(new Friend() { Id = 2, Name = "Josh" });

list.Add(new Friend() { Id = 3, Name = "Smith" });

list.Add(new Friend() { Id = 4, Name = "Andrew" });

AvailableDropZones = list;

}



ObservableCollection<Friend> availeble;

public ObservableCollection<Friend> AvailableDropZones

{

get

{

return availeble;

}

set

{

if (availeble != value)

{

availeble = value;

OnPropertyChanged("AvailableDropZones");

}

}

}



ObservableCollection<Friend> selected;

public ObservableCollection<Friend> SelectedDropZones

{

get

{

return selected;

}

set

{

if (selected != value)

{

selected = value;

OnPropertyChanged("SelectedDropZones");

}

}

}



}



public class Friend

{

public int Id { get; set; }

public string Name { get; set; }

}

Changing mouse cursor on expanding rows

Hi,

I'm using a TreeListView with many rows and columns. Expanding rows takes some time. That's why I want to change the mouse cursor to a wait cursor during the time the rendering of the rows takes place.
I found a solution for this problem for the TreeView in standard WPF:

private void TreeNodeExpanded(object sender, RoutedEventArgs e)

{

TreeViewItem tvi = e.OriginalSource as TreeViewItem;

if (tvi != null)

{

if (tvi.ItemContainerGenerator.Status != GeneratorStatus.ContainersGenerated)

{

EventHandler itemsGenerated = null;

itemsGenerated = delegate(object s, EventArgs args)

{

if ((s as ItemContainerGenerator).Status == GeneratorStatus.ContainersGenerated)

{

(s as ItemContainerGenerator).StatusChanged -= itemsGenerated;

tvi.Dispatcher.BeginInvoke(DispatcherPriority.DataBind,

(ThreadStart)delegate

{

Mouse.OverrideCursor = null;

});

}

};

tvi.ItemContainerGenerator.StatusChanged += itemsGenerated;

Mouse.OverrideCursor = Cursors.Wait;

}

I tried to rewrite the example for the TreeListView. Unfortunately, the ItemContainerGenerator of the TreeListView does not (unlike other older examples I found in this forum) contain a "Status" property or a "StatusChanged" event.

Is there another way for changing the mouse cursor during rendering time? All I need is an event that is raised when the rendering is finished.

Thanks a lot and best regards,
Frank

Interactive ToolTip

Hi,

In my application, I implemented and Interactive ToolTip which consist to have a tooltip always open with a usercontrol inside of it which contain buttons. When the user click on the buttons, action is taken and the popup is close.

I use it like this :

                    <Button Margin="20" Content="ToolTip" Width="80" HorizontalAlignment="Left">
                        <i:Interaction.Behaviors>
                            <ctrlToolTip:ToolTipCustomBehavior>
                                <local:UCToolTip />
                            </ctrlToolTip:ToolTipCustomBehavior>
                        </i:Interaction.Behaviors>
                    </Button>

What I would like to do is to use my interactive tooltip with each appointments. I mean I would like to do something like the custom tooltip demo for the ScheduleView but with my interactive tooltip, how I can do it?

Thank's
Alain
