Hi there,
I have a request to creat two chart in the same page and I want to refresh the two chart at the sametime.
I send the update request at the front page, code as below：
JsChartViewer.get('chart4').streamUpdate();
JsChartViewer.get('chart5').streamUpdate();
Then, I want to get the id of the JsChartViewer that sends the current HTTP request, but it didn't work, code as below：
if (RazorChartViewer.IsStreamRequest(Request))
{
Console.WriteLine("clientID=" + RazorChartViewer.GetSenderClientId(Request));
if(RazorChartViewer.GetSenderClientId(Request).Equals(realtimeChartViewer.ID))
return File(realtimeChartViewer.StreamChart(), Response.ContentType);
else
return File(roundMeterChart.StreamChart(), Response.ContentType);
}
The clientID shows empty, so, how can i get the chart id from Http request? Thanks.

Hi Eric,
Thank you very much for reporting this issue to us. We are able to reproduce this problem and is working on a fix. In the mean time, please obtain the clientID with the following code:
string clientID = Request.Query["cdDirectStream"];
The above is how ChartDirector obtains the clientID. For some reasons, it does not work inside our library, but it works if used directly in the razor page .cshtml.cs code.
Best Regards

I appreciate you very much for your help.
Now, I can catch the ID from the front page by using the code you provided.
Best Regards
