Create New screen with child and grandchildren RRS feed

  • Question

  • I have three tables in the database and here are their relationships:

    Asset [0..1 to 1] Computer [1 to Many] HardDisk

    I have succeeded in creating a screen that allows user to create an "Asset" and its child "Computer". However, I wanted to add a datagrid of HardDisks that links to Computer. How can I achieve that both for CreateNew and Details screen?

  • In screen designer to the left you will have your 'Computer' property and listed in that should be an item named 'Add HardDisks'. Click on this to add a 'HardDisks' collection property. Add this collection to your screen, likely below the asset/computer details.

    If this is HTML client then add some button(s)/item-click for the in-built HardDisks-AddAndEditNew/EditSelected. If it is Silverlight the datagrid will have these buttons already.

  • Thanks for your reply! However, while it works for child entity, the grandchildren does not appear to work this way i.e. "Add HardDisks" does not appear at all.

  • Would you mind providing us a screen shot of the screen designer to which you want to add the Harddisks collection?
