Q. How do I set tooltips for datapoints, series or other items within Dundas products for Reporting Services?

A. Due to a limitation in Microsoft's implementation of Reporting Services only one tooltip text value per control is available. This is a limitation that affects all custom report items for Reporting Services, including all of our Reporting Services products, and as such there can only be a single tooltip over the entire control rather than over individual elements within the control.

Reporting Services offers alternatives, such as bookmarks and the Jump to Report action. For example, by setting up a Jump to Bookmark action on the chart you can click on a data-point and be re-directed to a section of a Table or Matrix on the report with the correct bookmark set. Another example is to use a Jump to Report action on the chart to reload the report and pass a parameter describing the clicked item, and display the report parameter value in a TextBox. To set these actions up, find the Actions tab of the Chart Values window.

Dundas products are able to offer many more interactive features on the .NET Windows Forms, ASP.NET and SharePoint technology platforms, so consider a move to one of these technologies if a high degree of interactivity is required when visualizing your data.
