How to make a XRFeaturePictureBox show a user added point location in WF5 and zoom to it?

The default input parameter for a report seems to be an object ID. The XRFeaturePictureBox shows the corresponding feature and zooms to it.

But I would like to pass a point location that a user added in a WF5 form and let the XRFeaturePictureBox

• show the point
• zoom to the point
• at a given extent that is passed to the report in another parameter or that is specified in the report itself (1:1000 and 1:10000 scale)

How can I accomplish this?

Kind regards, Eric
