Property Value

Type: Grid..::..GridHighlighting
The highlighting settings.


While Cell highlighting, the Grid blends the highlighting color with the background color of the Cell. It takes into account the alpha-channel of the Color to prevent from the background color erasing. 255 value of the alpha channel means that the highlighting color is opaque, 0 - transparent.

If the fading effect is enabled, the alpha-value of the highlighting color will evaluate with time. During the highlighting Interval each RefreshInterval the Cell will be repainted with a new highlighting color.

    //Set a refresh interval of 30 milliseconds to repaint the cell

    //The object will notify the grid through the INotifyPropertyChanged, and the grid will automatically 
    //start the highlighting process for the affected cell.
    //If the call comes from the non-GUI thread, the grid will synchronize them without blocking the calling thread.
    product.Price = 12.34;

    //Another way to highlight the cell. The cell will be highlighted for 2 seconds with the red color and fading effect
    Cell cell = grid.Rows[0]["Price"];

Thread Safety

The returned class is not thread safe, but notifications from the data object are safe.
