Use of ProgressBar in WPF also add it in Status bar with animation effect

In this article i will show you, how to use progress bar in wpf (Window Presentation Foundation) and how to add it in status bar dynamically. Actually i explained it with basic information, today i will explain more about it. In this article, first to add a status bar in the page after that add a TextBlock control in it. Now the code look like :


<Grid>

        <StatusBar Name="sbar1" Background="BlueViolet" VerticalAlignment="Bottom">
            <StatusBarItem>
                <TextBlock>Status:</TextBlock>
            </StatusBarItem>
        </StatusBar>
    </Grid>

Now, create a new function just after the InitializeComponent() method, it means you can view your progress bar on window load.  

Code behind code

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media.Animation;

namespace WpfApplication2
{
    /// <summary>
    /// Interaction logic for progressbar.xaml
    /// </summary>
    public partial class progressbar : Window
    {
        public progressbar()
        {
            InitializeComponent();
            
            createprogressbar();
        }

        private void createprogressbar()
        {
            ProgressBar pb2 = new ProgressBar();
            pb2.IsIndeterminate = false;
            pb2.Orientation = Orientation.Horizontal;
            pb2.Width = 100;
            pb2.Height = 25;
           
            Duration dur = new Duration(TimeSpan.FromSeconds(30));
            DoubleAnimation dblani = new DoubleAnimation(200.0, dur);
            pb2.BeginAnimation(ProgressBar.ValueProperty, dblani);
            sbar1.Items.Add(pb2);

        }

  
    }
}

Now, code generate the following output:

Use of ProgressBar in WPF also add it in Status bar with animation effect


Here,
  1. Create a ProgressBar class object also set some data members like width, height etc.
  2. Set the animation by BeginAnimation method( )

Accept only number by TextBox using Jquery

You can say, how to apply restriction on input using Jquery. Here, meaning of restriction is, TextBox accept only numbers. Everyone know that TextBox control take character,string, numeric and special character as a input. But in some application we need only single feature like, it accept only number. So, the first question raise in my mind, how to do this, what is the logic behind this.
Logic behind this:
  1. First to get the key code like number 8 == backspace, some following keycode available here 
  2.  Now, match the keycode with the input character, if match then input character are not allowed.
Here are simple example of it:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Accept only numbers</title>
<script src="scripts/jquery-1.10.2.js"></script>
<script>
$(function () {
$('#Text1').keydown(function (er) {

if (er.altKey || er.ctrlKey || er.shiftKey) {
er.preventDefault();
}
else {

var key = er.keyCode;
if (!((key == 8) || (key == 46) || (key >= 35 && key <= 40) || (key >= 48 && key <= 57) || (key >= 96 && key <= 105))) {

er.preventDefault();
}

}


});

});

</script>

</head>
<body>
    <form id="form1" runat="server">
    <div>
<input id="Text1" type="text" />
    </div>
    </form>
</body>
</html>
Now code generate the following output:

Accept only number by TextBox using Jquery

How to use OpenFileDialog control in wpf to read txt file

Today i am talking about OpenFileDialog control. This control is used for picking some files from computer drive or location. I have already learn about OpenFileDialog control in windows form article. Today, the same article i cover using WPF. The logics are same in all language but some presentation of the language are different Like previous article cover by windows form and this article present by xaml language. Lets take a simple example: In this example, we will pick the text file from computer and read this file by using TextBox.

<Grid>
        <TextBox x:Name="textBox" HorizontalAlignment="Left" Height="44" Margin="39,33,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="300"/>
        <Button x:Name="button" Content="Browse" HorizontalAlignment="Left" Margin="344,33,0,0" VerticalAlignment="Top" Width="130" Height="44" Click="button_Click"/>
        <TextBox x:Name="textBox1" HorizontalAlignment="Left" Height="152" Margin="59,108,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="386"/>

    </Grid>


Code behind file

  private void button_Click(object sender, RoutedEventArgs e)
        {
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.DefaultExt = ".txt";
            ofd.Filter = "Text Document (.txt)|*.txt";
            if(ofd.ShowDialog()==true)
            {
                string filename = ofd.FileName;
                textBox.Text = filename;
                textBox1.Text = File.ReadAllText(filename);
            }

        }
Here OpenFileDialog control is exist in Microsoft.Win32 namespace. So use it by using "using" keyword. If you want to take only text file by this control then use Filter property. After picked file you can read this by using ReadAllText method of  File class.

Now , code generate the following output
