Method Detail

render

void render(RendererCellReference cell,
            T data)

Called whenever the Grid updates a cell.

For optimal performance, work done in this method should be kept to a minimum since it will be called continuously while the user is scrolling. It is recommended to set up the cell's DOM structure in ComplexRenderer.init(RendererCellReference) and only make incremental updates based on cell data in this method.

Parameters:

cell - The cell. Note that the cell is a flyweight and should not be stored outside of the method as it will change.

data - The column data object
