Hello guys,
Pls help with the above issue, I tried using dotnet.highchart for avoiding above problems but it got stuck in updatepanel refresh issue.
Not sure why highchart and dotnet.highchart having implementation differences.
In Highchart:
  • Have to add tag in web.config and use it in ascx like <highchart:PieChart .
  • Works prefect in updatepanel postbacks and usercontrols etc.
  • Problem is that it don't provide enough properties to handle dynamic colors setting and legend click handling.
In DotNet.Highchart:
  • Have to use label in ascx and from codebehind lbl.text=chart.tohtmlstring.
  • It provides dynamic color setting and legend click handling.
  • But this code do not handle updatepanel refresh properly, it got disappear on updatepanel postback.
Guys ............pls....
