UltraDropDown and Multiple Bands
posted

Is it possible for the UltraDropDown to show hierarchical data in bands?  I see the setup for the child bands but when I have a data set with a relationship of parent and child rows, I only get the parent row with no way of getting to any children.

Any insight would be great.

    Hi Gary,

        No, UltraDropDown does not support hierarchical data.

        If you want to create your own dropdown that supports this, it's probably not as complicated as you might think. What you do is start with an UltraTextEditor and an UltraWinGrid. Use the ButtonsRight collection on the UltraTextEditor and add a DropDownEditorButton and set the Control property of the button to the grid. Presto, instant dropdown grid control. You can even use it in a grid cell by assigning the EditorControl property of the grid column to the UltraTextEditor.

        Then you just have to handle events like BeforeEditorButtonDropDown (to select the appropriate item on the list) and some events of the dropdown grid to handle what happens when the user picks a row.
