No MouseOver effect on the child control inside RadPane

Sorry, Problem solved, this is not due to RadDocking implementation but application bug.
Please ignore this issue
Thanks

********************************
Hi,

Basically in my main window i have a left hand browse list and right hand side document host displaying radpane in tab form using MVVM

<telerik:RadDocking Grid.Row="1" Grid.ColumnSpan="2" BorderThickness="0" Padding="0" IsEnabled="{Binding Path=IsWebLoading, Converter={StaticResource ibcConverter}}" PreviewClose="RadDocking_PreviewClose">

<telerik:RadSplitContainer InitialPosition="DockedLeft">

<telerik:RadPaneGroup>

<telerik:RadPane Header="Menu" telerik:RadDocking.SerializationTag="PaneLeft">

<views:BrowsePanelView Margin="0" VerticalAlignment="Stretch" x:Name="browsePanelView" DataContext="{Binding Path=BrowsePaneVM}"/>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup modules:PaneGroupExtensions.ItemsSource="{Binding Path=DocPanelTabCollection}" SelectionChanged="RadPaneGroup_SelectionChanged">

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

</telerik:RadDocking>

However, i encountered strange behavior, i.e. the child control inside the RadPane does not have Mouse Hover effect (neither Left or right hand side), i.e. the cursor will not turn to "hand" when mouse over a button or a link inside the child control. But mouse click function work as per normal.

Anything i did wrong here?

Thank you

Column Selection Color

Hello, when selecting a cell, the row is highlighted. I would like to have the cells on selection by column, not by row. I'm using dynamic columns, so I'm not sure how to do this. I tried e.Cell.Background = Brushes.Red; at the cell level but the colors didn't change.

Thanks,
Scott

Load VirtualQueryableCollectionView items based on ID instead of index

We are using the RadGridView with a VirtualQueryableCollectionView as Itemsource using WPF and EF.
This works great for paging and scrolling, however we can't figure out how to deal with the following situation:

- We sort the grid by a property, name for instance.
- Then, outside of the grid, the name property is altered
- Our viewmodel receives a message that the item has changed

What we want to do now, is to refresh the grid, with the current item still selected.
However, since the name has changed, we don't know the index that has to be queried to get the item with the id of the changed item.

So the question is: knowing the ID of an entity, how can you make VirtualQueryableCollectionView load the item with that ID into the grid?The same situation arises when we want to select a entity (with known id) that has been newly created outside of the viewmodel.

We use the following VirtualQueryableCollectionViewHelper to create the set the VirtualQueryableCollecitonView.

QueryGenerator(QueryableXenoxContext) returns an EntityQuery

public class VirtualQueryableCollectionViewHelper<T> where T : Entity

{

public IEventAggregator EventAggregator { get; set; }

public

VirtualQueryableCollectionViewHelper(Func<QueryableXenoxContext, EntityQuery<T>> queryGenerator, queryableXenoxContext queryableXenoxContext, XenoxGridView gridView)

{

EventAggregator = ClientIocContainer.Instance.GetExportedValue<IEventAggregator>();

QueryGenerator = queryGenerator;

QueryableXenoxContext = queryableXenoxContext;

GridviewControl = gridView;

DoNothing = i => { };

View = new VirtualQueryableCollectionView<T>

{

LoadSize = 30,

VirtualItemCount = 100

};

View.ItemsLoading += (sender, args) => LoadInternal(args.StartIndex, args.ItemCount, DoNothing);

View.FilterDescriptors.CollectionChanged += (sender, args) => LoadInternal(0, View.LoadSize, DoNothing);

View.FilterDescriptors.ItemChanged += (sender, args) => LoadInternal(0, View.LoadSize, DoNothing);

View.SortDescriptors.CollectionChanged += (sender, args) => LoadInternal(0, View.LoadSize, DoNothing);

if (gridView == null)

{

ScrollIndexIntoView = DoNothing;

}

else

{

ScrollIndexIntoView = i => gridView.ScrollIndexIntoCenterOfView(i);

}

public void Load(int currentIndex, int pageSize)

{

LoadInternal(currentIndex, pageSize, ScrollIndexIntoView);

}

public void Refresh(bool scrollToIndex = false, int currentIndex = 0)

{

var postLoadAction = scrollToIndex ? ScrollIndexIntoView : DoNothing;

LoadInternal(currentIndex, View.LoadSize, postLoadAction);

}

public IEnumerable<T> GetAllCollectionItems()

{

return QueryableXenoxContext.Load(QueryGenerator(QueryableXenoxContext)).Entities;

}

private void LoadInternal(int currentIndex, int pageSize, Action<int> onLoaded)

{

if (currentIndex < 0) currentIndex = 0;

//also load content above current item

pageSize = pageSize*2;

var loadStartIndex = currentIndex - pageSize / 2 < 0 ? 0 : currentIndex - pageSize / 2;

var entityQuery =

QueryGenerator(QueryableXenoxContext)

.Sort(View.SortDescriptors)

.Where(View.FilterDescriptors)

.Skip(loadStartIndex)

.Take(pageSize);

entityQuery.IncludeTotalCount = true;

try

{

QueryableXenoxContext.Load(entityQuery, LoadBehavior.RefreshCurrent, lo => {

if (lo.TotalEntityCount != -1 && lo.TotalEntityCount != View.VirtualItemCount) {

View.VirtualItemCount = lo.TotalEntityCount;

}

View.Load(loadStartIndex, lo.Entities);

onLoaded(currentIndex);

}, null);

}

catch (InvalidOperationException)

{

EventAggregator.Publish(new ErrorReportedEvent("Error loading items. Possible cause: too many items selected"));

}

Row double click

Hello. I have a problem with row double click. I use next code:

protected override void OnMouseDoubleClick(MouseButtonEventArgs e)

{

var element = InputHitTest(e.GetPosition(GetRowForItem(SelectedItem)));

if (element != null)

{

if (DoubleClickCommand != null && DoubleClickCommand.CanExecute(DoubleClickCommandParameter))

DoubleClickCommand.Execute(DoubleClickCommandParameter);

}

base.OnMouseDoubleClick(e);

}

And some times InputHitTest return null. I can see that it happens when I scroll (Horizontal) to the right to the columns which aren't located in visible area. But if I resize gridView and some new columns will be located in visible area, InputHitTest will return right value. (My visual tree = RadDocumentPane -> ScrollViewer -> Canvas -> ContentControl -> RadGridView) Thanks.

FocusManager and RadWindow

Hello,
I have a RadWindow with just a label and a textbox :

    
            <telerik:RadWindow x:Class="TestWpf.MainWindow"    
        
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    
        
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    
        
                    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"    
        
                    Header="Test" Width="400" Height="200"    
        
                    FocusManager.FocusedElement="{Binding ElementName=tbxUser}">     
        
                <Grid>    
        
                    <Label Content="User : " Height="28" Name="lblUser" />    
        
                    <TextBox Height="23" Name="tbxUser" Width="120"/>     
        
                </Grid>    
        
            </telerik:RadWindow>

When I open the window I would have the focus in the textbox. So I add the FocusManager.FocusedElement attribute to the RadWindow but it doesn't work.
If I transform RadWindow to standard Window it works.
Is there another way to do this ?

Thanks in advance for your answer.
