I have a Telerik RadGridView Bound to ObservableCollection of defined type.. On Updating the value of a particular property in that type, the corresponding Observable collection is getting updated but not the RadGridView.. Below is the XAML: <pre><code><ComboBox Grid.Column="4" Width="100" Margin="4" ItemsSource="{Binding Path=ResultUnits, Mode=OneTime}" SelectedValue="{Binding Path=ResultUnit}"/> <telerik:RadGridView ItemsSource="{Binding Path=Results, Mode=TwoWay}" FooterRowStyle="{StaticResource GridViewFooterStyle}" Width="{Binding RelativeSource={RelativeSource AncestorType= ScrollViewer}, Path=ActualWidth}" ColumnWidth="*" RowIndicatorVisibility="Collapsed" EditTriggers="None" IsFilteringAllowed="False" AutoGenerateColumns="False" AllowDrop="False" CanUserFreezeColumns="False" CanUserReorderColumns="False" CanUserDeleteRows="False" CanUserInsertRows="False" ShowGroupPanel="False" ShowColumnFooters="True"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Quantity" DataMemberBinding="{Binding Path=Quantity}"/> </telerik:RadGridView.Columns> </telerik:RadGridView> </code></pre> Below is the View Model Code: <pre><code>public class ViewModel { private const decimal PoundsToKilograms = 0.45359237M; private const decimal GramstoPound = 0.00220462262M; private ObservableCollection<Result> results; public EnvironmentalSummaryViewModel() { this.results= new ObservableCollection<Result>(); } public ObservableCollection<Result> Results{ get { return this.results; } set { this.results = value; } } public string ResultUnit { get { return this.resultUnit; } set { if (this.resultUnit != value) { this.resultUnit = value; this.UpdateGridViewValuesOnResultUnitChanged(); } } } private void UpdateGridViewValuesOnResultUnitChanged() { bool isEnglish = this.resultUnit == this.resultUnits[0]; this.results.ToList().ForEach(result => { decimal weight = isEnglish ? result.Weight * GramstoPound * 1000 : environmental.Weight * PoundsToKilograms; result.Weight = Math.Round(weight, 2); }); ((IHaveOnPropertyChangedMethod) this).OnPropertyChanged("Results"); } } </code></pre> Object Class: <pre><code>public class Result{ public decimal Weight { get; set; } } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
