Implementation Guidelines and Conventions

When implementing IGridProvider, note the following guidelines and conventions:

Grid coordinates are zero-based with the upper left cell having coordinates (0, 0).
Merged cells will report their Row and Column properties based on their underlying anchor cell as defined by the UI Automation provider. Typically, it will be the topmost and leftmost row or column.
IGridItemProvider does not provide for active manipulation of the grid such as merging or splitting cells.
Controls that implement IGridItemProvider can typically be traversed (that is, a UI Automation client can move to adjacent controls) by using the keyboard.
