Hello everyone,
I am facing a strange problem, i have a case in which i have to generate a pie chart using MS Chart control in asp.net. (see the files attached ) . i do it in code behind i.e at run time. Chart get plotted well but problem arise when i click on any segment of pie for further drill down of that set of data. the 1st chart whose click event was fired get cleared up i.e nothing is shown in the chart as displayed but new chart get plotted on the value of post back value bind at run time. so to display chart image i have to call the event which builds the 1st chart again. similary when i try to click on chart2 to generate chart3. chart2 image gets cleared up. i am attaching image files and chart control & its code behind.
thanks nice share :)
