I have a grid with more than 150 rows. In that grid, we set AlternationCount property to "2" in order to highlight every 2nd row.
Dynamically, we have the code to select the row and focus the text box column during navigation by up/down key's. While doing that navigation after 15th row is getting struck.
Note: Up/down key's navigation is working properly if this AlternationCount property set to "0".
