Chart :: Random Error

[Kushan Shah]

Hi,

When I am opening any web page that contains Report which is having Telerik BAR Chart, The Report page is giving an error on page load. The error message and stack trace are as below,

 

“Source: Telerik.Charting

Message: An Unexpected error has occurred. Please review the InnerException for more information how to resolve the problem.

Stack trace: at Telerik.Charting.Chart.GetException(RenderEngine renderEngine, Exception ex) at Telerik.Charting.Chart.GetImage(Int32 width, Int32 height) at Telerik.Web.UI.RadChart.RenderClassic(HtmlTextWriter writer) at Telerik.Web.UI.RadChart.RenderContents(HtmlTextWriter writer) at System.Web.UI.WebControls.WebControl.Render(HtmlTextWriter writer) at Telerik.Web.UI.RadDataBoundControl.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.HtmlControls.HtmlForm.RenderChildren(HtmlTextWriter writer) at System.Web.UI.HtmlControls.HtmlForm.Render(HtmlTextWriter output) at System.Web.UI.HtmlControls.HtmlForm.RenderControl(HtmlTextWriter writer) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Page.Render(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) “

 

I am using Telerik.Charting.dll of version 2.0.3.0 in my project built on .NET framework 3.5 and I am binding Generic list to Telerik chart in C#.

 

I don’t face this error frequently but it occurs sometimes only and there is no particular situation for this error, It just occurs randomly.

Please let me know the solution for this asap.

Thanks in advance.

Hi Rikin Shah,

Unfortunately we are neither aware, nor capable of reproducing such a problem. The stack trace provided is very generic and does not help much with identifying the source of the problem. In order to help we would need to be able to repro the issue under controlled conditions in order to provide a fix or a work-around. Any help in that regard will be greatly appreciated.

We apologize for the inconvenience.

Sincerely yours,

I am using the latest version of the ASP.NET Ajax tools and I get the same error.
I have a RadGrid on a ascx control along with the chart. I update the chart when the user selects a Row in the Grid. I tested this on a test page and the code works fine. When I move it to my user control it blows up with the same error.

Any thoughts or help would be appreciated!

Thanks,
Ed

Hi Edward,

We would love to help out, but we need a runnable sample that we can debug for you. Sending in a project will greatly facilitate this process.
