Hello,

I tried with code and its works correct.

<telerik:RadBarcode ID="RadBarcode1" runat="server" Text="*123422*" Type="Code39"
            ShowChecksum="False"></telerik:RadBarcode>

Note : Please re-install telerik beta version and check again.

HI..Vasil, i test the example on: IE9, FireFox 12.0, Chrome 19, but the result is equal...

The new component HTMLCHART work, only the PieChart not work, not appear.

The new component ODataDataSource, the first example not work, the example ODataDataSource / Integration with RadListView see to work, the data in the grid appear.

Thank

Hello Aurelio,

Strange really if it does not appear in any browser, it probably is some server side error and the svg is not rendered at all.
Could you test it in the online beta demos here:
http://demos.telerik.com/aspnet-ajax-beta/barcode/examples/firstlook/defaultcs.aspx
And see if you will get different behaviour.

Kind regards,

HI. Vasil...
In the demo http://demos.telerik.com/aspnet-ajax-beta/barcode/examples/firstlook/defaultcs.aspx it's work OK in any Browser...
At this point it seems that the problem is the ASP.NET Development Server, i investigate on this..

Thanks

Hi, with IE9, if set the compatibility View (button in IE9 on the field Url), the barcode appear ok...
This function is avaible only in IE, in chrome  and Firefox actualy the barcode not appear.....(mystery)

Thank
Aurelio

Hello Aurelio,

In compatibility view(and for the older browsers like IE7 and IE8) the SVG markup in the page gets converted to VML dynamically client side using some JavaScript.
This means that the SVG is already transferred to the client, since it is converted successfully in these browsers. So the problem is not in the development server.
You can try to use some developers tools for Firefox like FireBug to inspect the elements and see if the barcode is actually rendered on the page.

I am not sure if the svg as vector format depends on some gpu acceleration that the browsers can use. If so, missing video drivers could cause problems, but it would happen when viewing both online and local demos. Just throwing ideas here, not really sure what can cause the SVG in one page to be non visible and in the same page opened from live to be visible.

</div>

but the line is not visible.

I have found the problem, it's the separator of number, if change witdh firebug the "," width "." the line is draw. (width="1,851852%" change to width="1.851852%" x="98,14815%" to x="98.14815%" the line appear.

Hi Aurelio,

I can confirm that this is a bug in Radbarcode, when creating these strings numbers are formatted to string without specifying a culture, which will means that the current server culture is used. I our server the culture is US and the decimal separator by default is '.' So in SVG's that are rendered from our online demos strings are like width="1.851852%". But in your server, the culture has comma as separator and the SVG is rendered wrong. We will review the code of PieChart for the same issue as well.

We will fix this for the official release so the Barcode's rendering to be independent of the server's culture. Thank you for helping is solving this, as appreciation i am updating your telerik points.
