Hi,

with the Q2 2013 update the SelectionChanged event of RadListBox does not fire anymore if an item is selected via code and the RadListBox is currently not visible. Is this new behaviour intended? I've switched back to the previous version.

Regards,
Michael

Multiple instances of RadMap with Tile Caching enabled

Hello.

In our solution we have to display multiple maps in different views of the application. We use different instances of the BingMapProvider for each of the map created. If we enable Tile Caching on at least two of the providers soon we run into the problem of accessing to the same cache file from two threads simultaneously, resulting in exception.

Is there any workaround for this issue?

Thanks.

Edittemplate selector in Outlookbar with Gridview

Hello

I am trying something that I think the Outlookbar isn't created for, but I've no way else to do it (that I know of so please correct me if I'm wrong). Here is the story:
The view that i am creating has a gridview with grouping. The user can click on an item and edit its value. This can be a string, int, enum and so on. So i created a edittempateselctor that selected the right template. Everything worked, but then the costumer wanted something like the outlookbar to display the values. So I created that, but my problem is that my edittemplate isn't working anymore. The selected template is null.
This is the working grid code:

<UserControl.Resources>

<custom:EditTemplateSelector x:Key="EditTemplateSelector" />

</UserControl.Resources>

<telerik:RadGridView Grid.Row="2"

ItemsSource="{Binding ListCollectionView, Mode=TwoWay}"

SelectionMode="Single"

AutoGenerateColumns="False"

CanUserDeleteRows="False"

CanUserFreezeColumns="False"

CanUserReorderColumns="False"

CanUserInsertRows="False"

RowHeight="30"

ColumnWidth="200"

BorderThickness="0"

ShowColumnHeaders="False"

ShowGroupPanel="False"

RowIndicatorVisibility="Collapsed"

EditTriggers="CellClick">

<telerik:RadGridView.Columns>

<aucxis:GridViewDataColumn DataMemberBinding="{Binding SubID}" IsReadOnly="True"/>

<aucxis:GridViewDataColumn DataMemberBinding="{Binding DataValue}"

CellEditTemplateSelector="{DynamicResource EditTemplateSelector}"

Width="Auto"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

this is the edittemplateselector.cs:

public class EditTemplateSelector : DataTemplateSelector

{

private IMessageBoxHandler _messageBoxHandler;

public DataTemplate BoolDataTemplate { get; set; }

public DataTemplate FloatDataTemplate { get; set; }

public DataTemplate IntDataTemplate { get; set; }

{

if (_messageBoxHandler == null)

_messageBoxHandler = DependencyInjection.Container.Resolve<IMessageBoxHandler>();

var dataObject = (DataObject)item;

if (dataObject == null)

{

const string nullValue = "This item has a nullvalue and can't be edited";

if (_messageBoxHandler != null)

_messageBoxHandler.Show(nullValue, "Let op!", MessageBoxButton.OK, MessageBoxImage.Warning);

PolarChart Degrees Clockwise?

Hi there,

to display some wind directions it would be nice if it is possible, to set the degrees in the PolarChart clockwise.
But they always appear counter clockwise.
Is it possible to that?

Best regards

RadGrid sometimes shows phantom rows

We are seeing a problem occasionally where, when switching the data displayed in the grid, some of the prior rows continue to display (see attached). These rows seem to just hang there since their location is not necessarily immediately following a valid row. Which is one way we know these are not actual rows that are part of our dataset.

One way to make this happen is to go into insert mode on a cell and then click elsewhere (in our case it is in a tree control) to make the grid reload with new data that has fewer rows than it originally had. The hard part of this is that I have not been able to reproduce this in a sample application. Our actual application's use of the grid is quite rich with features (virtualization, attached properties, non-auto generated columns, asynch dataloading) so it is not easy to bring all this over to a sample. I do have my sample using the above except for the attached properties.

Has anyone seen anything like this? Any clues as to how to prevent? It doesn't just happen if you are in insert mode but that is a sure-fire way to make it happen. I've tried having the code call CancelEdit on the grid before it switches the data but that did not help.

I've attached 2 screen shots. One shows the phantom rows without having been in insert mode prior to capturing this screen. The other shows the case when the user was in insert mode. You can see the phantom row showing the insert indicator on the left. I've drawn a red box around these phantom rows in these screen shots.

Thank you, Valerie

Keep Item In List after drag/drop

I am using two RadListBoxes as well as a ItemCollection. The are bound to observable collections of business objects. When I drag items between them, I don't want the item to be removed from the collection, but rather just a copy placed where it was dragged to. How would I keep the items in the list? It seems no matter what I do, the item is removed from the list that it was drug from.
