Microsoft .NET Framework 3.5 Chart Controls

June 10, 2009 | In Development |

Microsoft released an add-on to the .NET 3.5 framework last year to provide built-in chart controls for ASP.NET applications. You need to download the chart controls for Microsoft .NET Framework 3.5 and optionally the Add-on for Visual Studio 2008 (this puts the controls in the toolbox for you). There is also an installation guide and API guide.

By default, the Chart control is found in the Data tab in Visual Studio (if you install the add-on) , and can be dragged onto the page as with any other control; this inserts the default mark-up:

  <asp:Chart ID="Chart1" runat="server">
  <Series>
            <asp:Series Name="Series1">
            </asp:Series>
        </Series>
        <ChartAreas>
            <asp:ChartArea Name="ChartArea1">
            </asp:ChartArea>
        </ChartAreas>
    </asp:Chart>

Which produces a graph that looks like this:

You change the properties of the graph in the usual way from the Properties editor, items such as legends, display area, appearance etc, and crucial you can databind to the control from code.
