Thanks for your help! That works fine!

Hi, I guess my import code works fine. When I import the same xml file once, twice or three times without reseting it just adds the contents to the form.

When I bind the list entries of the dropdown (properties dialog) to the datasource, only an empty row and the first entry is shown ...

Hi, I want to populate a dropdown list when the form is openend. The values should appear depending on a select from a database, e. g. only rooms which are not booked should appear in the list.
