Chart Visual Studio disappears after postback

Question

i develop a website with VS2010.I have added a chart from toolbox that displays a line after a button is clicked.But while the chart appears fine the time i press the button, after a PostBack (for example i change the content of a textbox) the chart disappears.How can i make the chart keep showing after a PostBack?

can show some code? Are you checking IsPostBack before binding data? — Anuraj, Jul 17 '12 at 03:40

set EnableViewState="true"

<asp:Chart runat="server" ID="Chart1" EnableViewState="true">

Dunno why but asp.net charts seem to have viewstate off by default

it must generate a massive amount of jibberish in __viewstate. – Haoest Dec 07 '18 at 01:25
