    In this part of tutorial we shall demonstrate work of the grid with large data volumes on the example of Instrument

    browser.

    The business model already contains Instrument class. We shall add only one field (quoting currency) and create a lot of instruments in the application (e.g. 100000). For this purpose we shall modify Provider class and create an arbitrary list of instruments. As before, this list will be available as follows. Now let’s bind the grid to the data source. Memory consumption is one of the most important aspects of displaying large data volumes. When grid connects directly to application business logic, it significantly reduces memory consumption because there are no intermediate objects between the data layer and its presentation.

    Let’s create InstrumentBrowser control and place it at the main panel. We shall add a panel for instrument filtering and

    searching and the grid to this control. We shall configure grid in the designer and link it to the data source.The screenshot below demonstrates the results of application work.

    Let’s note an important detail. The collection of instruments contains about 100,000 elements. It is created when the application is launched. Total memory consumption of the entire application is about 45 MB. This collection is bound to the grid when Instrument browser tab is opened. After that, memory consumption increases to 59 MB. This means that the grid uses about 14 MB to display 100,000 elements. This amount of elements loads for about seconds.These indicators demonstrate of grid performance with realistic numbers of instruments.

    To navigate large data volumes a high performance filter is required. The grid provides a simple API for filter implementation. In this application many instruments have Weight, Shares, Capitalization values equaling 0. For more convenient data interpretation it is better not to display insignificant zeroes. Besides, it is better to add thousand separators for data formatting. Use of formats is the simplest way to implement this functionality. An example of creating a simple format for displaying digital information is provided below.

    Net Grid provides broad functionality of displaying various datagrid elements, such as cells, rows, headers and columns. The main objective of Dapfor is to develop high-performance software, specifically grids. Popular MVVM programming model that extensively uses databinding, data gridview to separate data from presentation.

    Playing different things with right and left hands is one of the most difficult skills the beginner pianist has to learn. Still, this is the core of piano playing and so it is something to be mastered at an early stage.

    I have known very intelligent adults despair to their piano teacher that they’ll ever get anywhere and I’ve known tiny little tots take to it like a duck to water. It’s one of those totally unfair situations when some brains seem to be set up right whilst others have the wiring right for most things but askew for piano playing!

    There is no need for anyone to despair with piano lessons ‘though. Just follow the advice below and you will find it easier to learn to play piano well. Sometimes you may feel you are getting nowhere but, although improvement may be slow it will still be there if you persevere.

    Consider these three steps to success.

    First make sure the piece you are trying is easy enough for you. Don’t try to run before you can walk. Adults often think they can race ahead past the first pieces in the book. Take it steady.

    Remember that it’s not just about training your fingers for the piano keyboard, but your brain has to cope with many, many new commands. So, take your time and take each piece steadily. Think about the hare and tortoise and when you start to play the piano, slow really is the best policy.

    Second, make sure you are confident about playing each hand separately. So well in fact that you would not be put off playing by any minor distractions.

    You should be able to play the left hand and sing the melody of the right hand at the same time or perhaps you might like to try playing the right hand and talking to someone at the same time. In other words, it must become part of your subconscious, so that your hands will just carry on, wherever your mind may be!

    Lastly, be sure to take everything slowly at first. When practicing independent hands take a very slow tempo. Watch your fingers playing the notes and know that you are in control.

    As soon as you start to play with both hands, cut the speed in half (way slower than you think you could play it or that you know it should go) and be very, very precise over how you play the notes. Watch the fingers playing the notes and be aware that you’re in control of every movement they make (you are, aren’t you?)!

    By following these simple steps, you will learn piano very quickly. For some people it will happen almost instantaneously whilst others will have to struggle, but if you persevere and keep repeating these steps the hands will eventually seem to know instinctively which piano notes to play and when.
