I have a Chart inside an UpdatePanel that is bound to a SqlDataSource. Outside the UpdatePanel, I have a dropdownlist. The SqlDataSource uses the selected value of the drop down list as a control parameter when selecting data that is used in the chart. By itself, this setup is working great. When I change the drop down list value, the chart updates. If the SqlDataSource returns 0 records, the chart shows the EmptySeriesMessage
However, I tried adding a Click event in the code behind. This is all I added:
Protected Sub RadChart1_Click(ByVal sender As Object, ByVal args As Telerik.Charting.ChartClickEventArgs) Handles
Can anyone help me? Is this a bug with the RadChart?
