Hi,

I have a simple grid defined like this:

<telerik:RadGridView Name="OrdersGridView" SelectionMode="Single" ItemsSource="{Binding PagedSource, ElementName=OrdersPager}" AutoGenerateColumns="False" ShowInsertRow="True" UseLayoutRounding="False" CanUserDeleteRows="False" RowEditEnded="OrdersGridViewRowEditEnded" AddingNewDataItem="OrdersGridViewAddingNewDataItem">

<telerik:RadGridView.SortDescriptors>

<telerik:SortDescriptor Member="Id" SortDirection="Descending" />

</telerik:RadGridView.SortDescriptors>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Id}" Header="{x:Static properties:Resources.Id}" UniqueName="Id" IsReadOnly="True" />

<telerik:GridViewComboBoxColumn DataMemberBinding="{Binding status}" Header="{x:Static properties:Resources.Status}" UniqueName="Status" ItemsSource="{Binding Statuses}" SelectedValueMemberPath="Key" DisplayMemberPath="Value" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding SocialSecurityNumber}" Header="{x:Static properties:Resources.SocialSecurityNumber}" UniqueName="SocialSecurityNumber" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding VisitDate}" Header="{x:Static properties:Resources.VisitDate}" UniqueName="VisitDate" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Department}" Header="{x:Static properties:Resources.Department}" UniqueName="Department" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Information}" Header="{x:Static properties:Resources.Information}" UniqueName="Information" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Recipient}" Header="{x:Static properties:Resources.Recipient}" UniqueName="Recipient" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding OrderDate}" Header="{x:Static properties:Resources.OrderDate}" UniqueName="OrderDate" DataFormatString="{} {0:yyyy-MM-dd}" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding OrderedBy}" Header="{x:Static properties:Resources.OrderedBy}" UniqueName="OrderedBy" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ContactEmail}" Header="{x:Static properties:Resources.Email}" UniqueName="Email" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ContactPhone}" Header="{x:Static properties:Resources.Phone}" UniqueName="Phone" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding DocumentId}" Header="{x:Static properties:Resources.DocumentId}" UniqueName="DocumentId" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding LoanDate}" Header="{x:Static properties:Resources.LoanDate}" UniqueName="LoanDate" DataFormatString="{} {0:yyyy-MM-dd}" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding LoanProcessedBy}" Header="{x:Static properties:Resources.LoanProcessedBy}" UniqueName="LoanProcessedBy" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ReturnDate}" Header="{x:Static properties:Resources.ReturnDate}" UniqueName="ReturnDate" DataFormatString="{} {0:yyyy-MM-dd}" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ReturnProcessedBy}" Header="{x:Static properties:Resources.ReturnProcessedBy}" UniqueName="ReturnProcessedBy" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

<telerik:RadDataPager Grid.Row="1" Name="OrdersPager" Source="{Binding Path=Orders}" DisplayMode="First, Previous, Next, Last, Text" IsTotalItemCountFixed="True" />

The data is initiated like this:

Orders = new QueryableDataServiceCollectionView<Order>(ordersContext, ordersQuery) { PageSize = 20, AutoLoad = true };

When I add sorting to the grid (as seen in the xaml above) the grid on first load displays both the 20 orders that should be in the grid and the 20 orders that should have been in the grid if there was no initial sorting defined. When I step to the next page and then back again to the first page, only the 20 orders that should be in the grid remains.

So for instance, the orders in the grid on the first page might initialy be:
1, 2, 3, ..., 20, 100, 99, 98, ..., 81

But it should be:
100, 99, 98, ..., 81

Am I doing something wrong, or is this a bug?

Best regards
Linus

TreeView tool tip

Hi,

I have noticed that (particularly under resource intense processes) that the tool tip can appear at the top left of my application rather than on the node hovered over.

Is there a fix for this

Adding reference to chart controls breaks intellisense in XAML

Trying to familiarize myself with the 4.5 WPF chart controls, but I found that adding a reference to Telerik.Windows.Controls.Charting breaks all intellisense in XAML. Same appears to go for Controls.Chart, and Controls.Data.

I'm using a build that seems to have the .DLLs dated Oct 17th.

Changing MouseOver/Selected slot brushes

Hi,
I am working on a month view in the ScheduleView control, and I've been trying to find a way to change the brushes of the slots (ie the TimeRulerMonthViewItem) when they are hovered over or selected.
Another related issue is srtetching that selection/hover border to fill the entire slot - instead of just under the GoToDayButton I want it to also show behind the button (the button is transparent of course).
Is there a way to apply this style changes?

Please see attached photo (hope it's comprehensible).

Thanks,
Nadav.
