I am using Hiearchial DataTemplates with normal DataTemplate that i saw in one of the forums in here. But i have a problem when the items are displayed properly but it is not expanded when clicked on the items. here is the code that i am using to Display two items at present.
The Link that i saw this way to display can be found here

XAML:

<Window.Resources>

<DataTemplate x:Key="PanelBarItemTemplate">

<StackPanel Orientation="Vertical">

<TextBlock Text="{Binding PropertyName}"/>

<TextBlock Text="{Binding PropertyValue}"/>

<TextBlock Text="{Binding Comments}"/>

</StackPanel>

</DataTemplate>

<HierarchicalDataTemplate x:Key="PanelBarHeaderTemplate"

ItemsSource="{Binding Items,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"

ItemTemplate="{StaticResource PanelBarItemTemplate}">

<TextBlock Text="{Binding Title}" />

</HierarchicalDataTemplate>

</Window.Resources>

<Grid>

<DockPanel>

<DockPanel DockPanel.Dock="Right" Width="350">

<Label />

</DockPanel>

<DockPanel DockPanel.Dock="Right" VerticalAlignment="Bottom">

<telerik:RadPanelBar ItemsSource="{Binding AccordionItems,UpdateSourceTrigger=PropertyChanged,Mode=TwoWay}"

ItemTemplate="{StaticResource PanelBarHeaderTemplate}" telerik:StyleManager.Theme="Windows7"/>

</DockPanel>

RichTextBox as DataForm field

I'm trying to create a DataForm that uses a RichTextBox as one of the entry fields. My problem comes in when I try to programmatically set the binding of the RichTextBox. Here's what I have:

private void editCabinetForm_AutoGeneratingField(object sender, Telerik.Windows.Controls.Data.DataForm.AutoGeneratingFieldEventArgs e)

{

if (e.PropertyName == "CabinetName")

{

e.DataField.Label = "Cabinet Name";

}

else if (e.PropertyName == "BriefDescription")

{

e.DataField.Label = "Brief Description";

}

else if (e.PropertyName == "Comments")

{

RadRichTextBox commentsBox = new RadRichTextBox();

//commentsBox.SetBinding(???, new Binding("Comments"));

e.DataField.Content = commentsBox;

e.DataField.Label = "Comments";

}

else

{

e.Cancel = true;

}

(Comments is a string variable)

I'm not quite sure what to use for the dependency property - any suggestions?

binding doesnt work for the first time

hi there,

in row_loaded method, we create a multibinding for background. converter is not called in first run.

-populate table (set binding in row_loaded)

-set background on viewmodel

-converter not called.

-clear table

-populate table (again create binding)

-set background, then it is called.

While in debug, when I checked PropertChanged.Target, in first run it is System.ComponentModel.PropertyChangedEventManager (doesnt work),
and in the second run, it is Telerik.Windows.Data.WeakEvent.WeakListener<System.ComponentModel.PropertyChangedEventArgs>.

Telerik version : 2011.1.411.40

MultiBinding multiBindingBackground = new MultiBinding();

multiBindingBackground.Converter = cellColorConverter;

Binding background = new Binding("Background");

background.Source = row.Item;

background.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;

//background.Mode = BindingMode.TwoWay;

multiBindingBackground.Bindings.Add(background);

multiBindingBackground.Bindings.Add(rcBinding);

Binding isBackgroundForBackground = new Binding();

isBackgroundForBackground.Source = true;

multiBindingBackground.Bindings.Add(isBackgroundForBackground);

multiBindingBackground.Bindings.Add(new Binding());

cellBase.SetBinding(GridViewCellBase.BackgroundProperty, multiBindingBackground);

BringIntoView for MVVM?

Hello,

I have a RadTreeView using a templated ItemsSource bound to a node collection in the view model. I have implemented a search on the tree, and the found node is programmatically selected within the view model (there is no code in the view). Do you have an example of how to bring the selected node into view using this type of MVVM structure?

Thanks for any help.

Polygon Point Coordinates

I'm drawing polyline objects, and when plotted I'm making them draggable. How can I get the coordinates for each point of the polyline after it's been dragged to a different location on the map?

Update: Figured it out (doh!):

MapPolygon thePolygon = item as MapPolygon;
                if (thePolygon != null)
                {
                    int pointCount = thePolygon.Points.Count - 1;
                    Debug.WriteLine("Number of Points: "+ pointCount);
                }

                Location[] locArray = thePolygon.Points.ToArray();

                foreach(Location loc in locArray)
                {
                    Debug.WriteLine("" + loc.Latitude.ToString());
                    Debug.WriteLine("" + loc.Longitude.ToString());
                }
