In the RC1 of expressapp framework the XtraReport has the ability to show a dialog based on filters used in the report. Is this something that might become a standard feature ? If not how can we implement this outside of the expressapp framework ? 

Hello Cornel,

Sorry, this feature is supported by XAF, but not by XtraReports. The problem is that XAF uses only XPO as a report's datasource, and in XtraReports a report can be bound to a wide range of different datasources. However, for now unlike XtraReports, the FilterContol, which is used in XAF to provide filtering, doesn't support all kinds of datasources. So, there are some problems with integrating the same approach into the XtraReports designer.

Nevertheless, we're planning to implement this feature in the future. If you wish it to be implemented, please track the following suggestion, and you'll be notified when it's implemented: http://www.devexpress.com/issue=AS2752.

To implement this feature manually, inherit from an XtraReport class and add the FilterOptions property to it to store your particular filter options. Then you need to handle a report's BeforePrint event and show the Filter dialog to end-users, and then apply the specified filter to a report's datasource. If this doesn't work for you, please contact our Support Team at http://www.devexpress.com/sc, and they'll certainly help you.
