HtmlChart - SqlDataSource

Isolate this demo as a stand-alone application
  • About this demo
  • C#
  • VB

This example shows how a RadHtmlChart can be bound to an SqlDataSource. The major properties are:

  • DataSourceID in the main tag sets the declarative data source for the entire chart. The DataSource property can be used for a programmatic data source if you create the connection in the code-behind.
  • DataFieldY for the series to point it to the desired column of the data source.
  • DataLabelsField for the x-axis labels to populate the items for the axis (it can also be applied to the y-axis).
