Hi Sameh,

When you are defining the ChartDefaultView in XAML, you need to create and associate the legend with the ChartArea in order to show it (as you are overwriting the default ChartDefaultView instance):

<telerik:RadChart Name="chrtStudent_Sessions" Margin="5" Grid.Column="0">

//...

    <telerik:RadChart.DefaultView>
        <telerik:ChartDefaultView>
            <telerik:ChartDefaultView.ChartTitle>
                <telerik:ChartTitle Content="Total Sessions" FontSize="11" />
            </telerik:ChartDefaultView.ChartTitle>
            <telerik:ChartDefaultView.ChartArea>
                <telerik:ChartArea ItemClick="ChartArea_ItemClick" Legend="{Binding ElementName=MyLegend}" />
            </telerik:ChartDefaultView.ChartArea>
            <telerik:ChartDefaultView.ChartLegend>
                <telerik:ChartLegend x:Name="MyLegend" />
            </telerik:ChartDefaultView.ChartLegend>
        </telerik:ChartDefaultView>
    </telerik:RadChart.DefaultView>
</telerik:RadChart>

All the best,
