Greetings,
I have noticed today that the following demo pages are broken when using the latest versions of Chrome & Edge:
https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/dateaxis/defaultcs.aspx
https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/pan-zoom/defaultcs.aspx
Each of these have a series of JavaScript errors that prevent the page from working:
RadHtmlChart.js:79 Uncaught SyntaxError: Invalid or unexpected token
at b.RadHtmlChart._parseObject (RadHtmlChart.js:79:46)
at b.RadHtmlChart._configurePlotArea (RadHtmlChart.js:128:47)

Hi Adam,
Thank you for reporting this issue!
We are working on fixing the broken Chart demos.
The fix will be live soon.

Hello Ralf,
I have checked the demos mentioned above and they all appear to function without any errors being thrown in the console. If you happen to find other broken demos, please share them with us.

Hi,
i got the same error in my own code using the RadHtmlChart.
Telerik have a BUG in the RadHtmlChart.ChartTitle.Text witch costs me 2 days of work because of the intransparent error above!
If you set a CrLf in the ChartTitle you got this error, too. -> Try it!

Hi Ralf,
How exactly is this bug happening on your end? I tried using the code in https://demos.telerik.com/aspnet-ajax/htmlchart/examples/appearance/configuringappearance/defaultcs.aspx and set the ChartTitle to CrLf, but everything works as expected:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ColumnChart.ChartTitle.Text = "CrLf";
}
}
Which version of the controls are you currently using? I have tested with the latest release (2025.3.825) and it works as expected.
I have also attached the sample project where I tested and would like to ask you to try and reproduce the error with the setup, then send it for additional investigation.
