Hi,

I'm using a VisualizationLayer along with MapShapeData to display road routes data on a RadMap.  Since the road routes have many waypoints, I used PolylineData to represent the data, and set up the layer with a collection of these items.

My problem is that at *detailed* zoom levels, the performance of the map suffers greatly.  If I zoom in to a single polyline at the most detailed level, I see the polyline rendering as a series of dozens of individual blurred strokes rather than as a connected line.  

My shot-in-the-dark guess would be that the calculation and rendering of all of these individual items is what causes the map to slow down, and that the rendering switches from a standard polyline to this new schema at a certain zoom level.  Do you know why this is happening and how I might fix it or work around it?

Working with version 2014.1.224.45 timeline. We are using groups to breakout timeline events into classifications.  My client asked if we can nest the groups (child groups).

For example, the high level group might be "Communications" and then we would have three expanders/groups under that which might have 3 different employee name groups. then under each employee name we would display via timeline events the communications.

Are nested groups possible?  If so, how?

I have an application where I use several RadDocumentPanes in the DocumentHost to keep various content. The users are (obviously) able to move panes around as they like. When the application closes the current layout is saved and restored automatically when the application is started again.

When I initially open the application and no saved layout exist the panes in the DocumentHost are showed in the default order. When I save that layout the display order is preserved perfectly in the saved XML output. All is good. If I however start to move panes around within the DocumentHost or move a pane out of the DocumentHost  and back again then the saved layout will not reflect the order in which the panes are displayed. And on load they will obviously be restored in a different order.

This can actually be reproduced easily using the Telerik WPF demo application. Perform the following operations using the "Save/Load Layout" example:

1. Open the example, press the "Save Layout" button and inspect the saved XML in the "Layout XML" pane. Note that the order in the XML of the DocumentHost part reflects the order which the two panes ("Layout XML" and "Document 1") are shown. All is good.
2. Move the "Panel Top 1" inside the DocumentHost and dock it at the end. Save the layout again and check the order of the XML. All is still good.
3. Move the "Panel Right 1" inside the DocumentHost and dock it somewhere in the middle. Save the layout again. Note that the saved order no longer reflects the displayed order.
4. Press the "Load Layout" button and note that the order in the DocumentHost is now switched around.

This problem does as far as I have been able to detect only affect the DocumentHost and not the other pane groups.

The problem is obviously highly annoying and I would like some pointers as to how I can either solve or work around it.

Hi,

is there an easy way to add a drop shadow effect to the docking toolwindow?

I need lazyloading filterable, groupable, sortable grid. Feature is that set of data constantly grows. Another feature is that datasource is wcf service. Can virtualqueryablecollectionview with gridview help in this scenario?
I will be grateful if you put a simple example

the regular - next to 0 works on my RadMaskedTextInput, but the one on the number pad doesn't.  Here is my style I'm using:
    <Style x:Key="UpperCodes6Mask" TargetType="telerik:RadMaskedTextInput">
        <Setter Property="FontFamily" Value="Segoe UI" />
        <Setter Property="Margin" Value="0 0 0 0" />
        <Setter Property="Width" Value="60" />
        <Setter Property="Height" Value="20" />
        <Setter Property="Padding" Value="0" />
        <Setter Property="Placeholder" Value=" " />
        <Setter Property="IsClearButtonVisible" Value="False" />
        <Setter Property="TextMode" Value="PlainText" />
        <Setter Property="SectionsNavigationMode" Value="None" />
        <Setter Property="IsLastPositionEditable" Value="False" />
        <Setter Property="SelectionOnFocus" Value="SelectAll" />
        <Setter Property="Mask" Value=">a6" />
    </Style>

First thank you so much for this control.  It is very useful.

I want to set a value in the search box, but I get a null error when I try

myAutoCompleteBox.SearchText = "TEST1";

How can I set what's in the textbox?  Value or Text isn't.  I suppose I could write a linq query and do selecteditem, but what if I just want to put text into that textbox that doesn't match anything in the list.

Also, I'm guessing there is nothing built in to highlight the matched text.  I can probably do this with templates though.

I'm also guessing that the virtualization is automatic and default.  I don't have to set this like I do in the combobox right?

Hello,
Could you please explain why I can't use the 'using' statement? How am I supposed to dispose the stream and clean up resources?
Thank you

I currently have a custom filter control defined for a column in a RadGridView and I'm trying to set Filter1 and Filter2 to default to "Contains" and the Logical Operator to "Or" in the xaml. However I'm having a hard time figuring it out. The code sample I'm working with is below. Can someone help me figure out how to change Fitler1, Filter2 and the logical operator default value?
