Hello:

I have tried to use the BulletGraph First Look sample project for the basis of my work; however, I am having serious issues getting the QualitativeRanges to bind properly to my ViewModel. Here is my xaml to aid with your assistance:

<telerik:RadGridView Grid.Row="1" Name="gridResults" AutoGenerateColumns="False" IsReadOnly="True" ShowGroupPanel="False" RowIndicatorVisibility="Collapsed" CanUserFreezeColumns="False" ItemsSource="{Binding Data}" CanUserDeleteRows="False" CanUserInsertRows="False" CanUserReorderColumns="False" SelectedItem="{Binding SelectedCoverageMeasure}">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="" UniqueName="DrillDown" Width="Auto" IsFilterable="False" IsResizable="False">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadButton Content="..." Command="{Binding DrillDownCommand, Source={StaticResource coverageViewModel}}" CommandParameter="{Binding}" ToolTipService.ToolTip="View Details"/>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Geography" UniqueName="Geography" MinWidth="100" Width="Auto" DataMemberBinding="{Binding Geography}" IsFilterable="True"/>

<telerik:GridViewDataColumn Header="Plan" UniqueName="Plan" Width="65" DataMemberBinding="{Binding Plan}" IsFilterable="True" />

<telerik:GridViewDataColumn Header="Actual" UniqueName="Actual" Width="65" DataMemberBinding="{Binding Actual}" IsFilterable="True" />

<telerik:GridViewDataColumn Header="% of Plan" UniqueName="PercentOfPlan" Width="85" DataMemberBinding="{Binding PercentOfPlanText}" IsFilterable="True" />

<telerik:GridViewDataColumn Header="Current Status" UniqueName="Status" Width="Auto" IsFilterable="False" >

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal" Height="20">

<Grid Width="45" Visibility="Collapsed">

<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="{Binding PercentOfPlanText}" />

</Grid>

<telerik:RadHorizontalBulletGraph Minimum="0" Maximum="100" AutoRange="False" Width="243" QuantitativeScaleVisibility="Collapsed"

ComparativeMeasure="{Binding Target}"

FeaturedMeasure="{Binding PercentOfPlan}"

FeaturedMeasureBrush="{Binding ActualMeasureBrush}"

QualitativeRanges="{Binding QualitativeRanges}"

>

</telerik:RadHorizontalBulletGraph>

</StackPanel>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Trend" UniqueName="TrendData" Width="Auto" IsFilterable="False" >

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadLinearSparkline

ShowFirstPointIndicator="True"

ShowLastPointIndicator="True"

ShowHighPointIndicators="True"

ShowLowPointIndicators="True"

ItemsSource="{Binding ActualMeasures}"

XValuePath="Date"

YValuePath="Value"

Width="150"

Height="20" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

I do have my ViewModel defined within my UserControl.Resources:

<UserControl.Resources>

<model:CoverageViewModel x:Key="coverageViewModel" />

</UserControl.Resources>

The QualitativeRanges property of my Viewmodel is defined as such:

public QualitativeRangeCollection QualitativeRanges;

The collection is being populated, but no qualitative ranges are being displayed in the BulletGraph. I am going crazy trying to figure out why. Does anyone have any ideas?

Thanks.
