I am new to Prometheus, in fact I am new to Telerik. I was very impress to see the online demo of Prometheus so I downloaded the trial and I am now trying to make this work, more specifically the RadChart component. After a complete day I have to say that it's still not working. I am following the instructions found at http://www.telerik.com/help/radcontrols/prometheus/ and I am now at the page "Quick Start: Create a Bar Chart with Simple Static Data" and I am trying my best to make this work but I must say that it is quite a challenge. I guess I choose to worst component to start with and that the others would probably way easier to get up and running.
So after doing what is mentioned in the Quick Start page where are the errors I encounter until now
First Error:
"Parser Error Message: Unknown server tag 'telerik:ChartSeries'."
After a bit of research I found that the instruction <%@ Register TagPrefix="telerik" Namespace="Telerik.Charting" Assembly="Telerik.Charting" %> has to be added to the top of the page. Why is this not done automatically by the wizard or as soon as a chart is drop on the design surface?
Second Error:
"The Chart http handler is not registered. Please, manually add the following line to your Web.config httpHandlers section:
<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2007.3.1425.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />"
Ok so I added this to my web.config but again why is this not done automatically?
Third problem:
"Field not found: 'Telerik.Charting.ActiveRegion.activeRegionList'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I read on the forum to put CreateImageMap="false" solve the problem, not sure why but I did it anyway.
Forth Error:
"Parser Error

Line 38: <FillStyle MainColor="199, 243, 178" SecondColor="17, 147, 7"></FillStyle>"
Ok so now I am stuck, can anyone help me ?
Btw I am using VS 2008, .Net 3.5
Thank you,
Eric

Onto your questions:
- Indeed, RadChart requires two Register directives. They are both added automatically if the chart is put in a page in Design mode. However, putting RadChart in a page in Source mode adds a single <telerik:RadChart> tag in the page, so it is only one Register directive necessary. At this moment there is nothing in the page, which would require the second register directive.
- We will research the possibilities for adding the http handler to web.config automatically. Thanks for this note.
- Please, check this forum thread for more details about this error. This will be fixed with the next official release, expected later this week.
- Can you send us a page in which this is reproducible? We will investigate it we'll get back to you with our findings. Thanks.
All the best,

This is a bit weird, Ves I just deleted the series part in the source and recreated the collection with the chart taks and now it works, it seems that the code has been written differently this time. The fist time I had something like "<telerik.charting.chartseriesitem name="Item 1" yvalue="10000">" and now I have something like "<telerik:ChartSeriesItem Name="Item 1" YValue="10000">"
This is way different, why is this happening?
Also is this normal that when I drag a RadChart in design view sometimes the only thing I see is a missing image icon? I am not using any custom skin but only the default one. And if I am lucky and I see the chart after draging it on the design view, later on when I re-open the same file in design view all I see is the icon of the missing image.
Thanks,
Eric
The problem with the messed up tag seems rather odd and definitely this is not desirable behavior -- can you reproduce it every time on a new website, or does it occur only in a specific project? Do you have a Telerik.Charting assembly in the website's /bin folder or only in the GAC? Does removing the Telerik.Charting assembly from the local /bin folder (if at all present) change the situation?
As for the VisualStudio2008 design-time issue -- we are unfortunately still unable to reproduce the problem in our local tests -- do you see a pattern on your end that leads to the broken image, so we can try to reproduce it here and continue with our investigation?
Looking forward to your reply.

The problem was because I had the Telerik assemblies in a local bin folder.
i.e.
I had them in the BIN folder at the root ->
/bin/Telerik*.dll
and also in one of my subfolders ->
/foo/bin/Telerik*.dll
After deleting the unneeded /foo/bin folder I'm no longer seeing the broken image for my charts or the strange tag behavior.
Thanks!!

I have a chart with an existing series:
<
telerik:ChartSeries
When I go through the Smart Wizard to add another series it adds it in the weird format with all of the Telerik.Charting tags:
<
Telerik.Charting.ChartSeries
<
FillSettings><ComplexGradient>
<
Telerik.Charting.GradientElement Color="222, 202, 152"></Telerik.Charting.GradientElement>
<
Telerik.Charting.GradientElement
We will need some more specific information in order to advise you more accurately -- can you reproduce the problem every time on a new website, or does it occur only in a specific project?
As you have specified, currently you have a Telerik.Charting assembly in the website's /bin folder -- do you have one in the GAC as well, and what version is it? Does removing the Telerik.Charting assembly from the local /bin folder (and referencing the one from the GAC) change the situation?

I can also replicate this issue, when using the chart wizard (bound to a SqlDataSource with two columns returned) deleting all series and adding a new one, clicking apply inserts
| <Telerik.Charting.ChartSeries Name="Hours Worked" dataxcolumn="DayOfYear" | |
| dataycolumn="HoursWorked" type="Line"> | |
| <appearance> | |
| <fillstyle maincolor="213, 247, 255"> | |
| </fillstyle> | |
| </appearance> | |
| </Telerik.Charting.ChartSeries> |
It may also be completely unrelated but VS 2008 Intellisense does not seem to be working at all for telerik:RadChart -> Series -> anything under it.
Thanks

The most probable reason you are experiencing these issues is a missing register directive in the ASPX for the Telerik.Charting assembly that contains core charting classes like ChartSeries.
Let me elaborate a bit more -- in order for the RadChart control to work correctly it needs register directives to the Telerik.Web.UI assembly:
| <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %> |
And to the Telerik.Charting assembly -- if this assembly is referenced from the GAC (by default the installer places it there), the directive should look like this (note you need to supply the correct version you have installed locally if it is not the latest):
| <%@ Register TagPrefix="telerik" Namespace="Telerik.Charting" Assembly="Telerik.Charting, Version=2.0.3.0, Culture=neutral, PublicKeyToken=d14f3dcc8e3e8763" %> |
if the Telerik.Charting assembly is referenced from the local /bin folder, the directive should look like this:
| <%@ Register TagPrefix="telerik" Namespace="Telerik.Charting" Assembly="Telerik.Charting" %> |
If the controls are installed correctly on your workstation and you drag and drop the chart from the toolbox, it should automatically insert both register directives; otherwise you need to add the second one manually.
Hope this helps.

I'm afraid I have already referenced the code like you suggested. To double test it I deleted everything on the page, and dragged a new RadChart component to the page, and bound it to a SqlDataSource. The resulting code was
| <telerik:RadChart ID="RadChart1" runat="server" DataSourceID="sqlHoursWorked"> |
| <Series> |
| <Telerik.Charting.ChartSeries Name="DayOfYear" dataycolumn="DayOfYear"></Telerik.Charting.ChartSeries> |
| <Telerik.Charting.ChartSeries Name="HoursWorked" dataycolumn="HoursWorked"></Telerik.Charting.ChartSeries> |
| </Series> |
| </telerik:RadChart> |
If it helps the page is also bound to a master page.
Thanks

We still believe the problem is triggered by incorrect reference to the Telerik.Charting assembly in the project that results in the incorrect tag prefix being added and the Intellisense not available.
We would suggest you to remove any Telerik.Charting.dll files (also *.refresh files) from your /bin folder, also remove any references to the Telerik.Charting assembly from your web.config file and then try to drag and drop a control from the toolbox.
Could you also confirm which version of the RadControls bundle have you installed, and could you specify the Telerik.Charting assembly version that resides in the GAC? If the problem persists, could you confirm that creating a brand-new project and dragging a control from the toolbox would result in the same erroneous behavior.
