Row Expander Not working properly with keyboard.
I have used row expander in a grid with rows to expand a row when he click on the Row.
Its working fine with mouse click on the Row.
But when we have focus on the row and when we click right arrow key on the row.
it should get expanded, but it not expanding.
Is it Rowexpander plugin bug with keyboard??
please help me out.
I would not count this as a bug. This feature is currently not implemented. You will need to extend RowExpander to listen to the key event and expand it manually currently.
I will add this to the list of features to concider.
