How to disable RadBusyIndicator in design mode?

We are using a RadBusyIndicator and everything is working fine, except the fact, that the BusyIndicator disables editing of enclosed controls in Design Mode.

Imagine there is a window with some buttons and textboxes and the BusyIndicator encloses these buttons and textboxes. During runtime enabling and disabling these controls via BusyIndicator works fine, but in VS2010 design mode you cannot e.g. shift the buttons around. Of course you can manually change the xaml code, but this is cumbersome.

Question: If I have integrated a BusyIndicator like this, how do I disable it during design time?

<telerik:RadBusyIndicator IsBusy="{Binding IsBusy, FallbackValue=False, TargetNullValue=False}" ...>
Some Buttons and TextBoxes</telerik:RadBusyIndicator>

[Solved] Moving RadPane clears GroupDescriptor

I have a RadGridView in a RadPane. The RadGridView has two fixed GroupDescriptors.

The pane is docked to the left by default and the first image shows the groupdescriptors working as intended. If I move the pane by dragging the header the groupdescriptors are instantly lost and I get the view in the 2nd attachment.

Is this normal behavior? If so is there a way to trap the event and stop this from taking place?

Thanks...

Implicit styles and Visual Studio Designer

Hello,
I'm creating a new WPF application and would like to use implicit styles. The application currently uses the Windows8 theme.
I've added the references to the Telerik assemblies, including Telerik.Windows.Themes.Windows8.
In App.xaml, I have:

<Application.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/System.Windows.xaml"/>

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/>

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Docking.xaml"/>

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</Application.Resources>

In Window1.xaml, I just have added a RadButton.
When I run the application, the button is displayed with the right theme, but the Visual Studio 2012 designer doesn't show the content of the button, as if the theme was not loaded.
How can I have the Visual Studio designer display the button correctly?

public kolekcja()
{

generatedata();
}

private void generatedata()
{
myrow row = new myrow();
row.Imie = "aa";
row.Nazwisko = "bb";
myCollection.Add(row);
myrow row1 = new wiersz();
row1.Imie = "cc ";
row1.Nazwisko = "dd";
myCollection.Add(row1);
}

public ObservableCollection<wiersz> MyCollection
{
get { return myCollection; }
set { myCollection = value; }
}

Is there any option to return filtered radgridview data rows (update myCollection ? or save rows to other collection ?) I would like create graph with the filtered data . I looking for the easiest way to create column header filter from GUI (Just like [DisplayAttribute( AutoGenerateField = false )] )

Remove connections when removing node?

When I remove a node (using the DEL key) I want its connections to be removed too. As it is now, I get these orphaned connections when removing a node.

This is the scenario:
1) Node A is connected - through connection X - to node B.
2) B is selected. I press the DEL key. Both B and X are removed.
3) I press Ctrl+Z. Both the removal of B and X are undone.

This behavior is absolutely necessary for our product. How can I accomplish this?

<Setter Property="Margin" Value="4" />

</Style>

<DataTemplate x:Name ="LeftPageTemplate" >

<StackPanel Margin="10" Background="LightGray">

</StackPanel>

</DataTemplate>

<DataTemplate x:Name="RightPageTemplate" DataType="Grid" >

<StackPanel Margin="10" Background="LightBlue">

<TextBlock HorizontalAlignment="Right"

Bind ADO.NET object to TreeListView cause sub items refersh problem

Recently, I've been working on a prototype to binding ADO.NET object to RadTreeListView for our project.
I have one DataSet which contains one DataTable. This table has 3 columns: ID, ParentID and Description. Create relation for this table between ID and ParentID columns. In another word, this is a self-referenced table.
Now create one DataView upon this DataTable and add needed filter for it.
1. Use the data set as the DataSource of RadTreeListView
2. Binding data view to ItemSource of RadTreeListView
3. Binding relation to ItemsSource of ChileTableDefinitions
See following codes:
<telerik:RadTreeListView Name="radTreeListView_left" DockPanel.Dock=

"Left" ItemsSource="{Binding TreeVM}" SelectedItem="{Binding SelectedEntityRow}">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Source=DataSetVM, Path=TreeRelation}"/>

</telerik:RadTreeListView.ChildTableDefinitions>

</telerik:RadTreeListView>

The hierarchy data can be display correctly in TreeListView. Since I am binding the data view to UI with Two Way mode, so I think if I detele one row in data view, the UI will be updated accordingly. But actually, only delete a root item can refresh correctly. Delete sub items on UI cannot refersh, they need additional refersh manually. For example, I have following structure in TreeListView:
Group 1
|_Item 1
|_Item2
Group 2
Delete Group2 in DataSet, UI will remove Group 2 automatically. But if I remove Item 2 in DataSet, UI will not update unless I refersh UI manually.
So my question is does anybody know how to solve this sub items refersh problem? This is very important for us to decide if choose Telerik or not. So please give any clue you may have.

Hierarchial in RadGridView

Dear Sir

I have a table(in SQL), like this: (there are some hierarchical data in this table)

ID F_ID Title
1 0 Hardware
2 1 Laptop
3 2 Sony
4 2 Toshipa
5 2 Asus
6 1 Monitor
7 6 LG
8 6 Samsung

I have used the RadGridview for hierarchical this data.
The XAML code is:

<telerik:RadGridView Grid.Row="1" Name="radGridView1" ShowGroupPanel="False" AutoGenerateColumns="False" ItemsSource="{Binding}" >
<telerik:RadGridView.ChildTableDefinitions>
<telerik:GridViewTableDefinition>
<telerik:GridViewTableDefinition.Relation>
<telerik:TableRelation IsSelfReference="True">
<telerik:TableRelation.FieldNames>
<telerik:FieldDescriptorNamePair
ParentFieldDescriptorName="ID"
ChildFieldDescriptorName="F_ID" />
</telerik:TableRelation.FieldNames>
</telerik:TableRelation>
</telerik:GridViewTableDefinition.Relation>
</telerik:GridViewTableDefinition>
</telerik:RadGridView.ChildTableDefinitions>
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding ID}" IsGroupable="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding F_ID}" IsGroupable="False" />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Title}" IsGroupable="False" />
</telerik:RadGridView.Columns>
</telerik:RadGridView>

and the C# code is:

private void Window_Loaded(object sender, RoutedEventArgs e)

        {

            MyLinqObjDataContext db = new MyLinqObjDataContext();

            radGridView1.ItemsSource = db.TBLTests;



        }

and the result of these code is shown in R1.png (attached file).

Now, Could you allow me to know:

1) How I could hide the "Laptop", "Sony", "Toshiba", "Asus" from root of radGridView. Because they are the child of "Hardware", I want to see them ONLY when the "Hardware" item, is expanded.

2) How I could hide the "+" icon, from beside of "Sony", "Toshiba", "Asus". Because they have not child (not expandable).

I am waiting for your help, PLEASE?
thanks;
