    Default Weblist Drag and Drop Problem

    Dragging from a non DataAware Weblist and Dropping to a non DataAware Weblist, does not display the data in the drop to Weblist. What could I be doing incorrectly? Or is this not suppose to work?

    I was able to add some code to get it to work, but just wondering if it should work as is?

    I believe nothing is “auto” when dealing with drag and drop.

    It is your responsibility to handle the data being sent and received.

    Have you looked at the sample code in weborder workspace?

    Copied the example exactly. Looked at their class also. Their example does not have non DataAware lists.

    After reviewing Dennis's (I think) DemoDynamicObjects.wo, I think I see that it is necessary to have different code for manually loaded lists.

    Also wondering if it is possible to Drag and Drop between Lists that have different tables and columns? Dennis?

    Demo 'Drag n' Drop between controls' does exaclty that!

    3 different grid/lists with different columns on all of them...

    It's up to you to handle it...

    Hi Sam,

    Just wanted to mention that if you are working to add some drag & drop to a project, Harm did a great demo at EDUC 2022 and that takes about 30 minutes to watch. The demo is part of the Hot Features course and it includes the use of OnManualLoadData. You can find the recording at the DataFlex Learning Center - https://learning.dataaccess.com/courses/educ-2022

    Note that there is a charge to have access to that content. Please, see https://support.dataaccess.com/Forum...arning-Center!
