Property 'x' does not exist in namespace

[Unisense]

Hi,

I have had this problem a couple of times now and i dont understand why it happens. 

Every time i try to use a property on for example an AreaSeries, the compiler tells me that this property does not exist in the telerik namespace "http://schemas.telerik.com/2008/xaml/presentation" even though the intellisense suggest the property. 

See attached image.

I have the following code for the graph:

<telerik:RadCartesianChart Grid.Column="1" Grid.Row="0" Grid.RowSpan="2" Margin="0,0,0,3" x:Name="lineSeries" ClipToBounds="False">
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis IsInverse="True" Name="verticalAxis" Title="Depth(µm)"/>
            </telerik:RadCartesianChart.VerticalAxis>

            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:LinearAxis Name="horizontalAxis" Title="Concentration(µmol/l)"/>
            </telerik:RadCartesianChart.HorizontalAxis>

            <telerik:ScatterPointSeries x:Name="pointSeries" XValueBinding="XValue" YValueBinding="YValue" ItemsSource="{Binding}">
                <telerik:ScatterPointSeries.PointTemplate>
                    <DataTemplate>
                        <Ellipse Width="17" Height="17" Fill="Blue"/>
                    </DataTemplate>
                </telerik:ScatterPointSeries.PointTemplate>
            </telerik:ScatterPointSeries>

            <telerik:ScatterLineSeries ItemsSource="{Binding}" StrokeThickness="1.5" x:Name="serie" Stroke="Red" XValueBinding="XValue" YValueBinding="YValue">
            </telerik:ScatterLineSeries>

            <telerik:AreaSeries StrokeThickness="2" Fill="Gray">
                <telerik:AreaSeries.DataPoints>
                    <telerik:CategoricalDataPoint Value="20"/>
                    <telerik:CategoricalDataPoint Value="40"/>
                    <telerik:CategoricalDataPoint Value="35"/>
                    <telerik:CategoricalDataPoint Value="40"/>
                    <telerik:CategoricalDataPoint Value="30"/>
                    <telerik:CategoricalDataPoint Value="50"/>
                </telerik:AreaSeries.DataPoints>
            </telerik:AreaSeries>

            <telerik:RadCartesianChart.Behaviors>
                <telerik:ChartPanAndZoomBehavior ZoomMode="Both" PanMode="Both"/>
            </telerik:RadCartesianChart.Behaviors>

            <telerik:RadCartesianChart.Grid>
                <telerik:CartesianChartGrid Name="chartGrid" MajorLinesVisibility="XY" MajorXLineDashArray="5, 5" MajorYLineDashArray="5, 5">
                    <telerik:CartesianChartGrid.MajorXLineStyle>
                        <Style TargetType="Line">
                            <Setter Property="Shape.Stroke" Value="Gray" />
                        </Style>
                    </telerik:CartesianChartGrid.MajorXLineStyle>
                    <telerik:CartesianChartGrid.MajorYLineStyle>
                        <Style TargetType="Line">
                            <Setter Property="Shape.Stroke" Value="Gray" />
                        </Style>
                    </telerik:CartesianChartGrid.MajorYLineStyle>
                </telerik:CartesianChartGrid>
            </telerik:RadCartesianChart.Grid>
        </telerik:RadCartesianChart>

Hello Jeppe,

I wasn't able to reproduce this issue locally. I prepared a sample project using the code snippet you sent, however please note that I changed the HorizontalAxis to be Categorical as you have defined CategoricalDataPoints in the AreaSeries and I wanted to display them.

The Stroke and the Fill of the area are properly applied and I don't receive any errors. I have referenced the three required assemblies for the ChartView components:

• Telerik.Windows.Data.dll
• Telerik.Windows.Controls.dll
• Telerik.Windows.Controls.Chart.dll

Please have a look at the solution and let me know if you receive any errors regarding the style-related properties.

Hi Tina Stancheva,

I dont get any errors when running your application. It is kind of weird but i must be doing something wrong.

But i have just found out that if i use ScatterAreaSeries it works fine. Still if i switch back to AreaSeries it doesnt work. 

So i think i'll use the ScatterAresSeries - but still dont understand why i cant use AreaSeries in my project :)

Thank you for your time and respons - have a nice christmas.

Best regards,
Jeppe
