Control ContextMenu in a Docking RadPane does not show up

I'm using RadControls for WPF Q1 2010 in WPF solution with the MVVM pattern.
When I implemented the RadDock control the ContextMenu of the controls inside the RadPanes stopped showing up. Instead the RadPane context menu pops up with the options: Floating, Dockable etc. If I place the exact same control (StackPanel in my case) in a data tamplate and reference it from the ContentTemplate property of the RadPane as shown below it work fine. This however is not an acceptable workaround in my case. Please help me.

<telerikDocking:RadSplitContainer Orientation="Vertical" InitialPosition="DockedRight">  
                <telerikDocking:RadPaneGroup> 
                    <telerikDocking:RadPane x:Name="Pane1" Header="Not Working ContextMenu" IsPinned="True"  > 
                        <StackPanel> 
                            <TextBlock TextWrapping="Wrap" Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit."/>  
                            <StackPanel.ContextMenu> 
                                <ContextMenu> 
                                    <MenuItem Header="Add"  /> 
                                    <MenuItem Header="Edit"  /> 
                                    <Separator/> 
                                    <MenuItem Header="Delete" /> 
                                </ContextMenu> 
                            </StackPanel.ContextMenu> 
                        </StackPanel> 
                    </telerikDocking:RadPane> 
                </telerikDocking:RadPaneGroup> 
                <telerikDocking:RadPaneGroup> 
                    <telerikDocking:RadPane Header="Working ContextMenu" IsPinned="True" ContentTemplate="{StaticResource template1}" /> 
                </telerikDocking:RadPaneGroup> 
            </telerikDocking:RadSplitContainer>

Pinning rad pane resets databound comboboxes
I have a number of databound comboboxes in a rad pane that load fine.

I have an issue that when I try and pin the pane all the comboboxes reset and I get

System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='comboItems'

a number of times.

Where combo items is defined as

<DataTemplate x:Key="DrillComboTemplate" >
                    <ComboBox SelectedValue="{Binding Value}" Width="{Binding Width}" HorizontalContentAlignment="{Binding Alignment}" ItemsSource="{DynamicResource comboItems}" />
                </DataTemplate>

Thanks

Another RadTileView Layout question

Hi!

We are using RadTileView control and would like to achieve the attached layout.
We removed the headers from the tiles and would like to have the window resizable (not fixed width tiles in restored form).
The problem is that tile number 3 is either next to tile 2 or in the beginning of the last row.
The XAML is below:

<Window x:Class="WpfApplication2.MainWindow"
        xmlns:Telerik_Windows_Controls_TileView="clr-namespace:Telerik.Windows.Controls.TileView;assembly=Telerik.Windows.Controls.Navigation"

RadGridView not refreshing after ItemsSource changes.
I have a RadGridView where the ItemsSource is a DataTable. The user is able to run a query which returns a List of objects which I convert to a DataTable using a WPF Converter .. All the binding is done through XAML.. Everything works very well so far. If the user reruns the query RadGridView gets correctly updated as expected.

Now the problem is when I add grouping. Rerun the query and now the grid is empty. However if I remove the grouping, all the expected data is displayed on the grid and now if I regroup everything works fine until the ItemsSource on the grid is changed again (by re-running the query). Any idea why this is happening?

I tried removing the GroupingDescriptors and re-adding them .. Also tried rebinding when the ItemsSource changed .. both options did not work. What am I missing here?

Thanks.

DateTimeFormat
Hi!

I am trying to customize a DateTimePicker to show the whole date and time in a custom format.
I found a way to customize the ShortdatePattern and the shorttimePattern separatly, but I would really require the FullDateTimePattern to work, as I have the format in a string (date and time combined) and I don't want to split it. I am using Q12013 WFP RadDateTimePicker

            dtp.SelectedValue = DateTime.Now;
            dtp.Culture = new CultureInfo("")
                              {
                                  DateTimeFormat =
                                      {
                                          FullDateTimePattern = "yyyy : MM : dd HH mm ss", //doesn't work
                                          ShortDatePattern = "yyyy : MM : dd", //works
                                          ShortTimePattern = "tt hh::mm::ss", //works
                                      },
                              };
Thanks in advance,

ScrollIntoViewAsync Exception
My users have been getting intermittent exceptions in the grids where we are scolling down to the new records after an add.  I am attaching the error message.  I added the try/catch to the sync to try to stop the unhandled exception error but it didn't seem to work because another user had an error after this code went out.

We are using version 2012.3.1129.40 (can't upgrade to 2013.1.220 for a few more weeks as this is our busy season).

Here is a sample of the code in one of the gridviews (used similar logic in the other grids):
private void grdCash_RowEditEnded(object sender, GridViewRowEditEndedEventArgs e)
        {
            this.grdCash.KeyboardCommandProvider = new DefaultKeyboardCommandProvider(this.grdCash);
 
            if (e.EditAction == GridViewEditAction.Cancel)
            {
                return;
            }
            else
            {
                //Update the entry in the view model
                if (DataContext is BatchCashViewModel)
                {
                    _batchCashViewModel.UpdateBatchCashRecordCommand.Execute(e.NewData);
 
                    if (e.Row is GridViewNewRow)
                    {
                        try
                        {

GridView ColumnHeader and ColumnGroup lines not matching up
Hi,

I created ColumnGroups for my GridView Columns and found out that Grid lines for ColumnGroup and Columns are not lining up and doesn't look good in UI. Is there any workaround for this? I am attaching a

1) magnified snapshot to illustrate the difference in lines (gridheaderwithcolumngroup_snapshot.png)

I have a sample project as well to show this but couldn't upload it because I am not allowed to attach anything else to this thread apart from image files.

Thanks,
Sandeep

Issue that combobox with VirtualQueryableCollectionView in RadGridView
Hi Guys,

I am very interested with Data virtualization, so I am refractoring my customer's old WPF project. Everything goes well but I encountered one critical issue when I use combobox with VirtualQueryableCollectionView  as GridViewDataColumn.CellEditTemplate.  Let me show it:

1. I make below collection binding to my combobox
private VirtualQueryableCollectionView _dataSource;
public VirtualQueryableCollectionView DataSource
{
    get
    {
        if (_dataSource == null)
        {
            _dataSource = new VirtualQueryableCollectionView(Manager.GetAll().AsQueryable()
                .OrderBy(ExpressionHelper.CreateOrderByExpression<T>(DisplayName)))
            {
                LoadSize = 20,
                VirtualItemCount = _manager.GetCount(),
            };
            //_dataSource.ItemsLoading += ItemsLoading;
            //_dataSource.ItemsLoaded += ItemsLoaded;
        }
        return _dataSource;
    }
    set
    {
        if (Equals(_dataSource, value)) return;
        _dataSource = value;
        OnPropertyChanged("DataSource");
    }
}
2. I used GridViewDataColumn.CellEditTemplate with below 
<telerik:GridViewDataColumn Header="{common:Translate RetailChain}"
                                           x:Name="Test"
                                           DataMemberBinding="{Binding BuyingOrganization.BO_CompanyName}">
                   <telerik:GridViewDataColumn.CellEditTemplate>
                       <DataTemplate>
                           <telerik:RadComboBox ToolTip="{common:Translate RetailChain_TT}"
                                                SelectedValue="{Binding BuyingOrganization}"
                                                ItemsSource="{Binding Source={StaticResource GlobalDataManager},Path= BuyingOrganizations.DataSource}"
                                                DisplayMemberPath="{Binding Source={StaticResource GlobalDataManager},Path= BuyingOrganizations.DisplayName}" />
                       </DataTemplate>
                   </telerik:GridViewDataColumn.CellEditTemplate>
               </telerik:GridViewDataColumn>

3. when I change inner combobox's selection, my viewmodel BuyingOrganization can be changed. From surface,
 it work right.   But if I take this cell out of Edit mode, the Null will be set to this BuyingOrganization. 

I debug it, the VirtualQueryableCollectionView will call MoveCurrentPosition to one null value.

How should I do? Can you give me some tips?

Thanks & Regards
