RadGrid: Predefined GroupDescriptors does not show GridViewDataColumn AggregateFunctions in GroupFooter/Header

RadControls for WPF Q3 2009.
I have predefined GroupDescriptors in XAML on the RadGrid, to show a Particular Group at start.
However the AggregateFunctions do not show up on the Group Footers or Headers. The Group Footers also look broken, as some grid lines are missing.
In the UI, if a user removes the prefined GroupDescriptor, and creates a new group through the UI with the same Column, the AggregateFunctions do show up.

I have also attempted to do this through C#, and get the same results.
Is there a particular way of predefining the GroupDescriptors so the Column's AggregateFunctions show up in the Group Footer?

Additional question. Is there way of defining a Column AggregateFunction to only appear in the GroupFooter, and not the header without writing a new ControlTemplate for the GridViewGroupRow?

Styling and creating own theme for RadGrid

Dear team,

Is there any quick way, that I can completely style the default RadGrid control and also create my own theme in fly? I'm finding it very difficult to style them, since I'm not from development side... It will be great help, if you can send me any samples for this. I found out one (http://www.telerik.com/community/forums/wpf/gridview/authoring-own-theme.aspx), which I was looking for, but this is not working with the Q2 2009 .dlls

We are using Q2 2009 version, which is free for MSDN subscribers (http://www.telerik.com/community/promos/msdn-wpf.aspx)

Many thanks

Column ReLoading Error

I am getting an error trying to change my column collection after it has been previously loaded.
I am using as much of an MVVM approach as I can, to work around some of the gridview properties that aren't DependencyProperties i had to get a little creative. Everything was working fine, but it seems as if something in the last release(2009.3.1208.35) is causing an error.

I have a property in my ViewModel that is a GridViewColumnCollection. A multibinding converter is used to get the Columns property of the Grid and set it into the ViewModel( which is the Datacontext for the Grid)

My Grid is declared as such:

    
            <telerik:RadGridView Name="gridviewRecordList" Margin="0,2,2,2" ScrollMode="RealTime" AutoGenerateColumns="False" IsReadOnly="True"  > 
        
                                <telerik:RadGridView.ItemsSource> 
        
                                    <Binding Path="GetAllRecords" Mode="OneWay"/>  
        
                                </telerik:RadGridView.ItemsSource> 
        
                                <telerik:RadGridView.SelectedItem> 
        
                                    <Binding Path="CurrentRecord"  Mode="Default"/>  
        
                                </telerik:RadGridView.SelectedItem> 
        
                                <telerik:RadGridView.ShowGroupPanel> 
        
                                    <Binding Path="CurrentListToolView.IsGroupingAllowed" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged"  /> 
        
                                </telerik:RadGridView.ShowGroupPanel> 
        
                                <telerik:RadGridView.ShowColumnFooters> 
        
                                    <Binding Path="CurrentListToolView.ShowColumnFooter" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" /> 
        
                                </telerik:RadGridView.ShowColumnFooters> 
        
                            </telerik:RadGridView>

Here's the Xaml for the column binding converter:

    
            <Label.Content> 
        
                            <MultiBinding> 
        
                                <MultiBinding.Converter> 
        
                                    <local:ColumnConverter /> 
        
                                </MultiBinding.Converter> 
        
                                <Binding ElementName="gridviewRecordList" Path="DataContext" UpdateSourceTrigger="PropertyChanged"/>  
        
                                <Binding ElementName="gridviewRecordList" Path="Columns" UpdateSourceTrigger="PropertyChanged"/>  
        
                            </MultiBinding> 
        
                        </Label.Content>

Here's ColumnConverter:

    
             If o IsNot Nothing And o.GetType.BaseType Is GetType(ASISplitWindowVM) And values.Count = 2 Then 
        
                                If values(1).GetType.BaseType Is GetType(GridViewColumnCollection) Then 
        
                                    Dim columnColl As GridViewColumnCollection = CType(values(1), GridViewColumnCollection)  
        
                                    Dim viewModel As ASISplitWindowVM = CType(o, ASISplitWindowVM)  
        
                                    viewModel.ColumnList = columnColl  
        
                                    viewModel.LoadListToolColumns()  
        
                                End If 
        
                            End If

The LoadListToolColumns Method reads through saved column data and creates GridViewDataColumns to add to the ColumnList Object(which since the ColumnList and the GridView.Columns are the same object it will update the UI when the ColumnList is changed).

This was all working fine, and still does work fine the first time it runs, but if I call LoadListToolColumns to try to load a different set of columns( after doing a ColumnList.Clear() ). Then I get an error, it works without error using version 2009.3.1103.35.

This error is thrown after all my code has executed successfully:

    
            System.NullReferenceException was unhandled

Exception from WindowPopupWindowImpl.Move(...)

Hi,

Attempt to set .Left and .Top property on RadWindow produces exception.

I’m trying to open modal RadWindow at the specific location on screen. The WindowStartupLocation is set to “Manual”. The code runs like this :

windowAdjustment.Left = _rightClickPoint.X;

windowAdjustment.Top = _rightClickPoint.Y;

windowAdjustment.ShowDialog();

It works perfectly the first time. But setting .Left property the second time causes exception “{“Object reference not set to an instance of an object"} System.Exception {System.NullReferenceException}”

The top of the stack trace :

at Telerik.Windows.Controls.RadWindowPopup.WindowPopupWindowFactory.WindowPopupWindowImpl.Move(Double left, Double top) in c:\Builds\...\Navigation\Window\WindowPopup\WindowPopupWindowImpl.cs:line 39

at Telerik.Windows.Controls.RadWindow.Move(Double x, Double y) in c:\Builds\...\Navigation\Window\RadWindow.cs:line 2028

at Telerik.Windows.Controls.RadWindow.OnLeftChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) in c:\Builds\...\Navigation\Window\RadWindow.cs:line 1713

Any ideas anyone ?

Sergey

Q309 Prerelease build 1419 references components in unavailable build 1418

Just downloaded build 1419 from the website. The Telerik.Windows.Controls.Docking.dll references build 1418 which is not publicly available. Anyone know a workaround for this until we get another prerelease from Telerik?

Memory leak?

Hello,
In my application I add a usercontrol containing raddocking to the visual tree. When I remove this usercontrol from the visual tree it stays in memory because it seems that raddocking still has a reference to something. See example code below.

    
            <UserControl xmlns:my="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"  x:Class="UserControl1"

RadSplitContainer.ChildrenOfType

hi,

i have this sample code:

                    RadPane FormRadPane = new RadPane() { Header = "Not Document Pane", CanDockInDocumentHost = false };         
            TextBlock txtBlock = new TextBlock();         
            txtBlock.Text = "This Pane Cannot be docked in to document host";         
            FormRadPane.Content = txtBlock;         
                     
            RadPaneGroup NewPaneGroup = new RadPaneGroup();         
            NewPaneGroup.Items.Add(FormRadPane);         
                     
            RadSplitContainer FormSplitContainer = new RadSplitContainer();         
            FormSplitContainer.InitialPosition = DockState.FloatingDockable;         
            FormSplitContainer.Items.Add(NewPaneGroup);         
                     
            MainDockingControl.Items.Add(FormSplitContainer);         

i've put a breakpoint on the last code row.

in the immediate window in run time i write:

                    FormSplitContainer.ChildrenOfType<RadPane>()         

and it i get no items i.e. "Items Count = 0".

meaning - the split container doesn't contain any panes.

is that a bug?

DocumentHost with no panes

hi,
i have a simple DockControl XAML:

    
            <radDock:RadDocking FlowDirection="RightToLeft" DockPanel.Dock="Bottom"> 
        
                            <radDock:RadDocking.DocumentHost> 
        
                                <radDock:RadPaneGroup> 
        
                                    <radDock:RadPane Header="Bottom Docked Control - Pane #1" CanFloat="true"> 
        
                                        <TextBlock>Bottom Docked Control - Pane #1</TextBlock> 
        
                                    </radDock:RadPane> 
        
                                    <radDock:RadPane Header="Bottom Docked Control - Pane #2" CanFloat="true"> 
        
                                        <TextBlock>Bottom Docked Control - Pane #2</TextBlock> 
        
                                    </radDock:RadPane> 
        
                                    <radDock:RadPane Header="Bottom Docked Control - Pane #3" CanFloat="true"> 
        
                                        <TextBlock>Bottom Docked Control - Pane #3</TextBlock> 
        
                                    </radDock:RadPane> 
        
                                </radDock:RadPaneGroup> 
        
                            </radDock:RadDocking.DocumentHost> 
        
                        </radDock:RadDocking>

what happens is when i float (undock) all of the panes from the DocumentHost i can't dock them again in the DocumentHost
only dock them to four sides, the compass doesn't give me the option, it's like the DocumentHost Disappear when it has no Panes
docking inside it, is there a solution to this situation or do i have to make sure that a least on pane will stay in the DocumentHost
so i can dock to it?

thank so much in advance.
