I am using a chart (column chart) to show variable data. That is, the user selects the critiera they wish to chart, then press a button, and the data is generated and displayed on the chart. They then repeat this process till their hearts content.
This all works fine, so long as the chart is not visible (on a tab which is not visible). But if it is, I get the error:
Invalid data source, this type is unsupported data type. Supported data types accepted as valid data source are DataTable, DataView, DataSet, Array and IList
I am binding the chart to a datatable. Roughly, the code I'm using is:
dt = new DataTable();// Generate dt dataultraChart1.DataSource = dt;ultraChart1.DataBind();
What am I doing wrong here? How can I load new data while the user is viewing the chart?
Hi fweeee,
From the information provided, I am unable to make any concrete conclusions; as dynamically modifying the data source or providing a new data source entirely, (granted that the provided data meets the criteria for the chart type) should not generate this error.
I have constructed and attached a sample to model your scenario, where the expected behavior is observed. Please take a look at this implementation and feel free to modify it so that it resembles your project more closely or if possible, please provide an isolated sample of your own that I can review, where this behavior is produced.
If you have any further questions regarding this issue in the meantime, please let me know.

Thanks Chris,
Your right - there was nothing wrong with my implementation as I had described it. The problem ended up being that I had assigned a binding source as the datasource for the chart at design time. As soon as I set the datasource to nothing in the designer, it all started working right.
Thanks for your help.
