Unknown server tag 'radC:ChartSeries'.

[pmwhelan]

Hi
I have an ASP.NET website which works fine.
One one page I use the radchart and it's all working fine.
at the top of that working page I have ...

<%

@ Register Assembly="RadGrid.Net2" Namespace="Telerik.WebControls" TagPrefix="radG" %>

Now I create a new page and I want a radchart on it

I do this ...

 

<%

@ Register Assembly="RadChart.Net2" Namespace="Telerik.WebControls" TagPrefix="radC" %>

and i put in this code ....

 

<

 

radC:RadChart ID="RadChart1" runat="server" Width="480px" Height="290px">

 

 

 

 

 

 

 

 

 

</radC:RadChart>

and it says "Chart has no or empty series?"

but if I put in this code ....

 

<

 

radC:RadChart ID="RadChart1" runat="server" Width="480px" Height="290px">

 

 

 

 

 

 

 

<Series>

 

 

 

 

 

<radC:ChartSeries Name="1">

 

 

 

 

 

<Items>

 

 

 

 

 

<radC:ChartSeriesItem YValue="1" Name="1"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="2" Name="2"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="3" Name="3"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="4" Name="4"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="5" Name="5"></radC:ChartSeriesItem>

 

 

 

 

 

</Items>

 

 

 

 

 

</radC:ChartSeries>

 

 

 

 

 

<radC:ChartSeries Name="2" YAxisType=Secondary>

 

 

 

 

 

<Items>

 

 

 

 

 

<radC:ChartSeriesItem YValue="10" Name="1"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="20" Name="2"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="30" Name="3"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="40" Name="4"></radC:ChartSeriesItem>

 

 

 

 

 

<radC:ChartSeriesItem YValue="50" Name="5"></radC:ChartSeriesItem>

 

 

 

 

 

</Items>

 

 

 

 

 

</radC:ChartSeries>

 

 

</Series>

 

 

 

</radC:RadChart>

It says 
Error 1 Unknown server tag 'radC:ChartSeries'.

Ok I got it
I had to do

<%

@ Register Assembly="RadChart.Net2" Namespace="Telerik.WebControls" TagPrefix="radC" %>

 

<%

@ Register Assembly="RadChart.Net2" Namespace="Telerik.Charting" TagPrefix="radC" %>

Now If I want to modify the chart in the code behind I get an error

Error 2 Type 'Series' is not defined.

Hi,

The class name is actually ChartSeries, so you need it like this:

Dim series As New ChartSeries("Series 1")

Hello Rishi,

The tag should be telerik:ChartSeries and not telerik:ChartsSeries.
