Object reference not set to an instance of an object.

[sachinj]

Hi,

I am dynamically creating a chart and I am getting the object reference error when I try to run the following code:

System.IO.

StringWriter MyTextWriter = new System.IO.StringWriter();HtmlTextWriter MyHtmlWriter = new HtmlTextWriter(MyTextWriter);chart1.RenderControl(MyHtmlWriter); //Crashes here with the above error

 It works fine some times but crashes other times. I am not able to figure out the reason for the crash. Can anyone provide me with any more insight.

Thanks.

 Here is the call stack for the crash.:
