WPF experience-Dialog Box call

It has been a long time before the blog was launched. Continue ....

Compared with winform, WPF has fewer dialog control. But it's all a family. You can use it if necessary.

Make a simple program to call a dialog. :

Simple call, code:

 

Code

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
    public partial class MainWindow : Window
    {
public MainWindow()
        {
            InitializeComponent();
        }       

public static string PicturePath = "";

private void btnShow_Click(object sender, RoutedEventArgs e)
        {
            Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

// Set filter for file extension and default file extension 

            dlg.DefaultExt = ".jpg";

            dlg.Filter = "JPEG Files (*.jpg)|*.jpg|PNG Files (*.png)|*.png|BMP Files (*.bmp)|*.bmp|All files (*.*)|*.*";



// Display OpenFileDialog by calling ShowDialog method 

            Nullable<bool> result = dlg.ShowDialog();


// Get the selected file name and display in a TextBox 

if (result == true)
            {

// Open document 

string filename = dlg.FileName;

                PicturePath = filename;

            }


this.image1.Source = GetImage();
this.image1.Width = this.picPanel.Width;
            image1.Height = picPanel.Height;


        }

private static BitmapImage GetImage()
        {
            BitmapImage image = new BitmapImage();
            image.BeginInit();
            image.UriSource = new Uri(PicturePath);
            image.EndInit();
return image;
        }


private void btnClear_Click(object sender, RoutedEventArgs e)
        {
this.image1.Source = null;
        }

private void btnSetBG_Click(object sender, RoutedEventArgs e)
        {
            System.Windows.Forms.ColorDialog color = new System.Windows.Forms.ColorDialog();
if (color.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
this.picPanel.Background = new SolidColorBrush(Color.FromArgb(color.Color.A,color.Color.R,color.Color.G,color.Color.B));
            }
        }

private void btnClose_Click(object sender, RoutedEventArgs e)
        {
this.Close();
        }


    }
}

Don't forget to reference system. Windows. form !!

 

By the way, there is a bug here: only the last button changes while stretching the form, and the rest remains unchanged. What's the problem? To be studied...
