Performance differences between PowerBuilder and mobile

Limitations

DataWindows in TreeView presentation style are restrained by all limitations for DataWindows in Group presentation style.

Collapsing, Collapsed, Expanding, and Expanded events cannot be triggered if the nested TreeView DataWindows.

The height for the Tree.level band cannot be negative value.

You can not set a column to current column using SetColumn function if the column cannot be focused.

If the ScrollNextPage function is called in the last page, the current row on mobile will be set to the last row. This is different from that in PowerBuilder.

On mobile, the SetSort function sorts data before groups data. This is different from that in PowerBuilder.

Event sequence difference

Difference

The TreeNodeSelecting, TreeNodeSelected, RowFocusChanging and RowFocusChanged events cannot be triggered in the preview mode.

Selecting Tree Node on mobile will sequentially trigger the events TreeNodeSelecting, TreeNodeSelected, RowFocusChanging, RowFocusChanged.

Clicking the TreeView DataWindow on mobile will trigger the following events in sequence: LButtonDown, RowFocusChanging, RowFocusChanged, TreeNodeDelecting and TreeNodeSelected.

On mobile calling ScrollNextPage function will trigger the following event in sequence: Rowfocuschanging, Rowfocuschanged, and ScrollVertial.

Collapsing or expanding the tree node will trigger the collapsing(/expanding), collapsed(/expanded) and Resize events on mobile in sequence.

Do not assign values to rows in the grouping column in a loop. You can use dot notation to directly assign values to corresponding rows.
