Disappearing Properties

I have discovered what I believe is a bug in PropertyGrid.

Here is a simplified explanation of the issue.

I have a MainWindow that has a PropertyGrid that has its Item property bound to a CurrentWidget. I have a ListBox that has its ItemSource bound to a Widgets collection and its SelectedItem bound to CurrentWidget (TwoWay).

I have a MainWindowViewModel that has a CurrentWidget property and a Widgets collection (Observable).

The Widget class just has four basic properties (ints, bools).

As you click through the Widgets in the ListBox (or arrow up/down), the properties of the selected widget are loaded into the PropertyGrid, but as you move through the items one less property is added to the PropertyGrid until the property count is zero and then it starts back at all of the properties and continues to work down to zero properties, etc.

We have noticed that this is only happening when we have AutoGeneratePropertyDefinitions set to true (the default).

I have created a small proof-of-concept application that isolates and illustrates the bug. Please advise on how to get this to you guys.

Thanks in advance!

Can't load RadDocking after saving the layout to IsolatedStorage

Child table ignoring relationship

Hi,
I have a single data context and within my edmx model I have 2 tables.

Table 1 (Parent Table) (Loads grdSAPBatches)
AUFNR Primary key
BATCH_Type
ENGINE_TYPE
START_DATE
START_TIME
PROGRAMMED_QTY

Table 2 (Child Table) (Loads grdSAPComponents)

AUFNR FK1
TAG_POSITION FK2
COMPONENT
MESSAGE

I have a Grid and I have set as follows following the sample to show Table 1 data and on expand of row I would want to see filtered table 2 data with the relationship being AUFNR - but the child table seems to be ignoring the relationship I specified in xaml and just loading all the table 2 data?

I have changed self reference to False and True and it makes no difference....

The VB I am using to load the data is as follows

Dim vwSAPBatchesViewSource As System.Windows.Data.CollectionViewSource = CType(Me.FindResource("TblSAP_BatchesViewSource"), System.Windows.Data.CollectionViewSource)

vwSAPBatchesViewSource.Source = context.fnGetSapBatches

Child Table

Dim vwSAPComponentsViewSource As System.Windows.Data.CollectionViewSource = CType(Me.FindResource("TblSAP_ComponentsViewSource"), System.Windows.Data.CollectionViewSource)

vwSAPComponentsViewSource.Source = context.fnGetSapComponents

The bold items are the imports in edmx to SP's in sql server - neither fn's take parameters as I assumed the grid would filter the child data automatically once the relationship was set?

RadDocking Multiple Custom Themes?

Hello,

I am attempting to theme two different RadDocking controls, within the same solution, each with its own custom theme. I have followed the instructions/example mentioned here and have been able to get the first theme applied. Is it possible to create a second theme to be applied to another RadDocking control?

I would also like to apply each theme in XAML, as demonstrated here in the RadDockingTheming Overview.

Thanks,
Frankie

How to Change the Description of Column Filter in RadGridView

Hi,

I am working on a RadGridView with a Column Filter. For some columns it's a Combo Box with list of values and their description.
I would like to display the description into the Column Filter, instead of their underlying value, which is not very meaningful for the users.

How can we achieve this?

Thanks
Ric Yik

XBap RadWindow adorner error on startup

Binding to an element in the RadPane.TitleTemplate

In my RadPane I have a Listbox that is part of a UserControl in the Content section that I need to bind to a ComboBox in the TitleTemplate section; is this possible? A co-worker suggested searching the visual tree but I'm hoping there's a better way. The code currently falls down on the ItemsSource binding in the UserControl. A XAML solution is preferred but code-behind is fine if that is what is required.

TitleTemplate:

<DataTemplate x:Key="TitleTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="Auto"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<ContentPresenter Content="{Binding}"/>

<StackPanel Orientation="Horizontal" Grid.Column="1">

<ComboBox x:Name="Top" ItemsSource="{Binding Source={x:Static TopLevelElements}}"/>

<ComboBox x:Name="Middle" ItemsSource="{Binding ElementName=Top, Path=SelectedItem.MiddleLevelElements}"/>

</StackPanel>

</Grid>
