SelectionTool is used for array group selection like select odd values or select even values from particular numbers range. This also select groups like 2, 3, 4, 1 etc... SelectionTool Class API SelectionTool class is main class of SelectionTool. This class provides rich options to select all, deselect all, select left half, select right half, select left half from already selected values, select right half from already selected values. Add custom group selection using 'Add' button. Properties Here in SelectionTool class has only two properties. The 'Range' used to define 'from value' to 'to value'. The 'SelectedRange' gives list of selected values from 'Range' value. Syntax public Range Range public List<int> SelectedRange Constructors This is one and default constructor. Syntax public SelectionTool() Events Here only one event 'SelectedRangeChanged' which fire when selected range changed from any source. For examples: Sele

NSSlider is WPF slider's alternative. Here NS means N-North and S-South. So, NSSlider is vertical slider in WPF. In this post, I will show reference API of this UI. NSSlider Class API NSSlider has one class and this is main class. NSSlider provides Minimum, Maximum, Change, Format, Value and Caption properties with one event which is ValueChanged event. Properties Here basic commons properties with syntax is below. Syntax public decimal Minimum public decimal Maximum public decimal Change public string Format public decimal Value public string Caption  Constructors This is one and default constructor. Syntax public NSSlider() Events Here is only an event ValueChanged. This event fire when Value property value being changed. Syntax public event EventHandler ValueChanged;  Example Of NSSlider <gui:NSSlider x:Name="NS1" Minimum="-50" Maximum="20" Change="0.1" Format="00.00$" Value="5" Caption="Demo"/> NS1.

There are three class(es) in color palette tool. 1] ColorPalette, 2] ColorCell, 3] AddColorCell. Today, I will write reference and example about color palette. This tool is available for private use only. And the API is written in WPF C#. 1] ColorPalette Class API This is a main class of my color palette tool. This class provides functionalities for set current color, add new cell, remove exist cell, and remove all exist cells. Also has an event fire while current color change. We also set functionalities of importing and exporting ColorPalette. Properties This property stores color and also fire an event CurrentColorChanged. Syntax public Color CurrentColor Constructors This is one and default constructor. Syntax public ColorPalette() Methods These methods are used for adding and removing ColorCell from the ColorPalette. Also used for importing and exporting ColorPalette. Syntax public void AddColorCell(ColorCell ColorCell) public void RemoveColorCell(ColorCell ColorCell) public void

Today we will discuss about async and await keyword. And will know some examples about Task. private async void MyTask() { await Task.Run(() => { // Code Here }); } Avoid use of void. use Task or Task<return_type>. private async Task MyTask() { await Task.Run(() => { // Code Here }); } It can use for non return value. private async Task<int> MyTask() { await Task.Run(() => { // Code Here }); return int; } Returns int values.

How To Get Removable Devices? Before using this code, You need to enable (check) Removable Storage in Capabilities (in Package.appxmanifest). Warning : Due to async and await keywords, The debugger might not receive some values at breakpoints.  StorageFolder Instance = KnownFolders.RemovableDevices; This how you can get Removable Devices. How To Get List Of Removable Devices? StorageFolder Instance = KnownFolders.RemovableDevices; IReadOnlyList<StorageFolder> Devices = await Instance.GetFoldersAsync(); How To Get Removable Devices By Array Index? Get devices using array index like Devices[0] indicate first device for example "C:", Devices[1] indicate second device for example "D:". If index out of range then it will gives you exception. StorageFolder Instance = KnownFolders.RemovableDevices; IReadOnlyList<StorageFolder> Devices = await Instance.GetFoldersAsync(); StorageFolder Device = Devices[0]; How To Get All Directories And All Files From Current Pat

I will create number validation in TextBox. This algorithm only allow numbers while user press any key. TB.PreviewTextInput += (sender, e) => { if (e.Text != "0" && e.Text != "1" && e.Text != "2" && e.Text != "3" && e.Text != "4" && e.Text != "5" && e.Text != "6" && e.Text != "7" && e.Text != "8" && e.Text != "9") { e.Handled = true; } }; Here is little demo on PreviewTextInput. I am researching on validations for TextBox. In future, I will create more detail about it.

This is little experiment about memory management and time management in WPF while we create millions of objects in small amount of time. Let's see first example while we create one simple class with no properties (empty class). Before we start, we must define some properties in MainWindow. private readonly int TotalObjects = 10000000; private int i = 0; private List<PointClass> Objs = new List<PointClass>(); private Stopwatch Timer = new Stopwatch(); private TimeSpan TS = new TimeSpan(); TotalObjects is variable. And this number used in loop for repeating same process. It means we will create PointClass's object in each cycle and store in Objs List<>. The 'i' is index for loop. Using Stopwatch we will calculate the time and store elapsed time in TimeSpan TS. This experiment uses two loop; 1] for loop and 2] while loop. public class PointClass { } First create empty class. This class hasn't any property. See the below example to see How much time

First we need to set some properties for window. The property WindowStyle will be None. Property AllowsTransparency will be true. WindowStartupLocation property will be CenterScreen. And The Background will be Transparent. Now you need to use Clip property for window reshape. <Window x:Class="Saatody.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:Saatody" Title="MainWindow" Height="500" Width="500" WindowStyle="None" AllowsTransparency="True" WindowStartupLocation="CenterScreen" Background="Transparent"> <Window.Clip> <PathGeometry>

Today I will show you, How to get pixel color from particular UIElement. Here we need two main class(es). RenderTargetBitmap and CroppedBitmap.
