    Hi Mani,

    I am not quite sure whether I understand the scenario correctly. Could you, please, provide ?
    • If you want to bind the HTMLChart to a database assigning to it specific values from the data tables, you can see how this could be done here: SqlDataSource
    • If you want to create the HTMLChart dynamically, accessing values from the code behind, you can refer the following live demo: Programmatic Chart Creation

    If non of the above is the case, could you, please, provide more detailed information on what exactly do you want to achieve?

    Hi Mani,

    Thank you for the clarification, bu unfortunately  RadHtmlChart cannot work with Eval expressions. In order to bind the control to a database you have to use a data source control (e.g., SqlDataSource, ObjectDataSource, LinqSqlDataSource, EntityDataSource) in the way shown in this live demo. You can control the data source and the columns of it which will be used for the HtmlChart with the following properties:
    • 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 table
    • DataLabelsField for the x-axis labels to populate the items for the axis

    If you are using the chart into a template of a databinding control, you can access the HtmlChart in its parent OnItemBound event and configure its values in it.

    I hope this information will be helpful for you.
