Sorting ItemPropertyDefinition.DisplayName

Hi,

I am creating the ItemPropertyDefinition(s) in code-behind. I add the definitions one at a time based on various user selections peculiar to my app. As I add a ItemPropertyDefinition to the ItemPropertyDefinitions collection, I would like the ItemPropertyDefinition display names to be presented in alphabetical order. Can this be done?

Thanks
Rich

Scroll bar problem

Hi,

This is treeview code:

<telerik:RadTreeView Grid.Row="2" IsRootLinesEnabled="False" IsLineEnabled="True" ItemsSource="{Binding DisplayDataList}" PreviewSelectionChanged="RadTreeView_PreviewSelectionChanged" telerik:StyleManager.Theme="{StaticResource MetroStyle}" FontFamily="{StaticResource font_global}" HorizontalContentAlignment="Stretch">

<telerik:RadTreeView.ItemTemplate>

<HierarchicalDataTemplate ItemsSource="{Binding TreeNodeList}">

<TextBlock FontSize="16" Text="{Binding TreeNodeID}" />

</HierarchicalDataTemplate>

</telerik:RadTreeView.ItemTemplate

</telerik:RadTreeView>

And this is tree node modle code:

public class AccountTreeNode

{

private Object treeNodeObject;

public Object TreeNodeObject

{

get { return treeNodeObject; }

set { treeNodeObject = value; }

}

private Type treeNodeType;

public Type TreeNodeType

{

get { return treeNodeType; }

set { treeNodeType = value; }

}

private ObservableCollection<AccountTreeNode> treeNodeList;

public ObservableCollection<AccountTreeNode> TreeNodeList

{

get { return treeNodeList; }

set { treeNodeList = value; Notify("TreeNodeList"); }

}

In the case of treeview's scrollbar displayed. The scrollbar will be uncontrolled movement when clicked one tree node in the treeview.
And tree node can be selected more than one.

If the scroll bar isn't displayed, the above problems would not have occurred.

Clear Description panel

Hi all,

I have a property grid which is populated when an item in a tree view is selected.

The appropriate description appears when you click a property in the grid. However, when a new item in the tree view is selected, although the new set of properties is loaded up the old description remains.

I need to be able to clear this when I click on a new item in my tree view

Thanks is advance

Adding button to busy indicator

Hi I am using the busy indicator while I have a simulator setting it self up. I need to give the user a method to perform an emergency stop if needed. I tried adding a button to the data template but clicking it seems to do nothing. Can this be done? Below is the XMAL and command definition

<telerik:RadBusyIndicator IsIndeterminate="True" IsBusy="{Binding IsVehicleRotating}">

<telerik:RadBusyIndicator.BusyContentTemplate>

<DataTemplate>

<Grid HorizontalAlignment="Center" VerticalAlignment="Center">

<Grid.RowDefinitions>

<RowDefinition></RowDefinition>

<RowDefinition Height="23"></RowDefinition>

</Grid.RowDefinitions>

<diControls:DILabel>

Vehicle is rotating

</diControls:DILabel>

<diControls:DIButton Grid.Row="1">

Emergency Stop

</diControls:DIButton>

</Grid>

</DataTemplate>

</telerik:RadBusyIndicator.BusyContentTemplate>

</telerik:RadBusyIndicator>

private RelayCommand emergencyStopCommand;

public RelayCommand EmergencyStopCommand

{

get

{

return emergencyStopCommand ?? (emergencyStopCommand = new RelayCommand(() =>

{

IsVehicleRotating = false;

vehicleStateController.EmergencyStop();

Cleanup();

}

));

}

.

DataFormatString based on Row not Column

So I have a basic DataFormatString based on columns but there will be rows that are a exception (they show percentage between the other rows) and I need to format those rows as a percentage number.

I've took a look into both Row- and CellStyleSelector and CellTemplateSelector but not sure any of these can do the trick because they don't seem to manage the DataFormatString.

RowStyle with <Setter Property="ContentStringFormat" Value="P" /> does nothing, probably because he tries to apply that to the whole row which of course is not a string.

Get parent grid view row IsSelectionActive Property

HI,

My grid view contains number of rows and one column in the grid view contains a list box.

I am using the below code to change the color of textblock placed inside the list box based on its parent grid view row.

<Style.Triggers>

</DataTrigger>
</Style.Triggers>

</Style>

Though its working fine but i want one more condition in this trigger to check wheather Parent grid view selected row's selection is active or not.For that i modified condition inside the trigger as mentioned below:

<MultiDataTrigger>
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type telerik:GridViewRow}}, Path=IsSelected}" Value="true"/>
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type telerik:GridViewRow}}, Path=Selector.IsSelectionActive}" Value="true"/>
</MultiDataTrigger>

But its not working. Can you please suggest which approach to use to get parent row's Selector.IsSelectionActive property.

Looking forward for your reply.
Thanks And Regards,
Kavita

Backstage vs application menu?

Hey there,
I'm pretty new with the ribbonview but i'm very confused with those 2 sub components, both seem to be pretty much the same thing to me (click on the topleft button, opens a zone).
What differenciates them? Which one should i use in which case? Can and should both be used?
I did look at the doc and manage to use both, but i really don't see where they differ in functional use.

RibbonView and RibbonWindow
