Word 2007 options like dialog

I there any code snippet (or already existing control) on how to make an option dialog like the one of Microsoft Word 2007.

I would like to use Telerik controls so that I can take advantage of the themes.

I'm using PRISM and my goal is to make a "options service" component in which different modules can push options view.

Regards,

Nicolas

Table width when exporting with RadDocument

Hi,

I've implemented this helpful example code (http://demos.telerik.com/silverlight/#GridView/PrintAndExportWithRadDocument) and it is all working as expected, however the table that is created does not take up the whole width of the page. I notice it uses the column widths of the RadGridView, however they are not ideal in the A4 pdf. I would like the table that is created for the pdf to size itself based on content. Is this possible, and if so, how would I do it? I figure it's got something to do with this line:

cell.PreferredWidth = new TableWidthUnit((float)columns[i].ActualWidth);

Thanks

RadTreeView + QueryableEntityCollectionView + Drag & Drop

I'm working on a project where I have a large amount of data stored in a database organized into a tree. I'm using the EntityFramework, so I'm using the QueryableEntityCollectionView to filter my data and a RadTreeView to display it.

However, I also need support for drag & drop to add/move/delete items. By default, the RadTreeView won't let me drop into this tree as it is. If it was an IList or an ObservableCollection, it will let me, but I need to be able to refresh/filter the visible nodes in the tree.

Is there a way to override the d&d support in RadTreeView to allow drops, and run custom code on drop complete?

I did see this post (http://www.telerik.com/community/forums/silverlight/treeview/use-drag-and-drop-to-rearrange-items-and-then-persist-order-back-to-database.aspx) but it's for silverlight and I don't think the WCF side is needed for a WPF + EF application.

Any advice?
Thanks!

Double-fired OnDrop for listbox inside RadTileView

When the list box lives inside a RadTileView, the OnDrop event will get fired twice with the same parameters.

<telerik:RadTileView>

<telerik:RadTileViewItem>

<Grid x:Name="LayoutRoot" Background="White">

<Grid.Resources>

<Style TargetType="ListViewItem">

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

</Style>

<DataTemplate x:Key="ApplicationTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Margin="5" Text="{Binding Name}" VerticalAlignment="Center"></TextBlock>

</StackPanel>

</DataTemplate>

</Grid.Resources>

<ColumnDefinition></ColumnDefinition>

</Grid.ColumnDefinitions>

Limit drop target

I have implemented a basic drag-n-drop using Telerik's new DragDropManager, pretty much the same as instructed here http://www.telerik.com/help/wpf/dragdropmanager-getting-started.html except that I am using ListView instead of ListBox.

Although it works, but I need help on the following two things:

How to I limit the drag-n-drop so that it can only happen between the two listviews? i.e. disallow dropping to the same listview as the drag source.
How to change cursor based on the above criteria? I try to monitor OnGiveFeedback(), but the sender is always the drag source...

Frozen groupheaders

Is it possible to 'freeze' the groupheader row?
This way the current group would always be visible while (vertically) scrolling the data in the gridview.

Custom Dialog Underneath ToolWindows

I have created a custom popup user control. This control covers the entire application with a gray semi-transparent overlay with a message in the middle.

I add the control like this which makes it the last control in the grid and putting it on top of all other objects.

Grid mainGrid = (Grid)App.Current.MainWindow.Content;

mainGrid.Children.Insert(mainGrid.Children.Count, this);

I have a docking control in this grid and as long as everything is docked the overlay works great. However, as soon as I pull one of the RadPanes into a separate ToolWindow that tool window is always on top of my overlay user control. Is there anyway to do an overlay that would be on top of the ToolWindow as well?
