I've included the map in one of my project. I took the example from the help documentation just to play a little bit with it before actually implemented in a production apps. The problem is that I cannot see any tiles. Everything else seem working (pan, zoom,...).

Anything that can help me? Maybe is because it have issue connecting to the web?

Accessing the dbf file

Is it possible to access the dbf file during the binding (see below):

this

.StateLayer.Reader.DataSource = new Uri(string.Format(ShapeRelativeUriFormat, "usa_states.dbf"), UriKind.Relative);

I would like to append some text to each of the state names, if I could do some sort of loop / foreach that would be great. Can you provide sample code?

Regards
Thomas

using data row with cell template selector

I need to apply a data template to a grid view cell using a cell template selector similar to the approach provided in one of the grid view demo's. My template looks like this:

</DataTemplate>

The data grid is bound to a data table, so I use the dataRowConverter to try to get the right column value out of the data row that is passed to it by this template. My problem is that in the converter, I do not have the index to the data row to get the corresponding value for the grid view cell being processed. How am I able to pass as a converter parameter the current cell header or name to the converter? Thanks for your help.

Object reference not set to an instance of an Object

I'm getting the error with a fresh installed machine (Windows 7) with a fresh install of Visual Studio 2010 Ultimate. My question is has anyone tried to install the WPF controls without having an earlier version of Visual Studio on the PC like VS 2008.

I ask this question because we took the same image I have (Windows 7) and added Visual Studio 2008 to the PC then added Visual Studio 2010 and the Install and controls from telerik work fine.

On my VS 2010 only I don't have some of the .net files like net 3.5 is not there just the major version ( IE 1.0, 2.0, 3.0 and 4.0) but there is no net 3.5 like on the VS 2008/VS 2010 machine.

I can't add any controls to the design space without getting the error. I hate to reimage my PC and add VS 2008 just to get the telerik controls to load.

Performance Issues

Hi,

I have started developing an application using the RadControls for WPF framework and have noticed that the performance of the docking and map controls aren't very good. When I drag the docking windows they are slow to respond to my mouse moves. The map is also also slow to respond to my panning actions in that the map is trailing quite a bit my mouse moves.

I don't have much in my application. Just the ribbon with 3 tabs and 1 group each (at the moment), the rad docking with a map in one of the panes and two other panes with Rad grids without any rows.

I am running a Core i7 so it should be fairly snappy, certainly if VS2010 is any indication of how fast a WPF application can be.

Cheers,
Clint

DragDrop XP problems

I'm dragging and dropping from two different listboxes. This works perfectly in Windows7. However, one of my clients who is on XP can't get this to work.

I've loaded up an XP VM and sure enough, it doesn't. I added some logging and found that in the DropInfo handler, DropImpossible is being passed in as the Status when they let go of the mouse on top of the control. When hovering over the control with the mouse down, it is passing DropPossible. However, it will not pass DropComplete upon release.

If you need me to set up a simple project as an example, let me know.

On a related note, the DragCue is not showing in XP as well. This may or may not be related. I set the e.Options.DragCue to a TreeViewDragCue in the DragInfo for DragStatus.DragInProgress.

RadComboBox ItemsSource Refresh removes selectedValue Binding

Hello,
I have a RadComboBox bound to an ItemsSource that is an ObservableCollection. When that ObserableCollection is changed the RadComboBox SelectedValue is set to -1 instead of the binding in the SelectedValue. The underlying object is not changed and still has the correct value.

Here is my binding.
<telerik:RadComboBox Name="cmbLocation" Margin="0 8 0 0" IsEditable="False" Width="95" ItemsSource="{Binding Lookup.LuLocation}" DisplayMemberPath="LocationDescription" SelectedValuePath="LocationId" SelectedValue="{Binding Path=Line.LocationId, Mode=TwoWay}" HorizontalAlignment="Left" />

How do I keep the binding as the ObservableCollection changes?

Thank you,
Rick

RadPane context menu in every child control

Hello,

I have a visual studio like docking layout.
Right clicking on controls that are placed within a RadPane always triggers a context menu that belongs to the RadPane itself ("Movable, Dockable, ..., Hide") and is not the built in context menu of that particular control where the event was triggered from (eg TextBox, FlowDocument, TreeView).

Is there a way to stop this behaviour? I guess it must be something really trivial, I am sorry for that.

Thanks for your kind help.

Marc

Edit: Handling MouseRightButtonUp in the toplevel parent container under RadPane and setting Handled to true will suppress the radpane context menu, but the context menues for any other control like treeviews, textboxes and flowdocuments as well.
