In this section we are going to learn how to use Windows Forms Controls in WPF. If you have ever compared the Windows Forms toolbox to that of the WPF toolbox then you will find many controls that are not in the WPF toolbox. However Microsoft has provided a way through which we can use of Windows Forms controls in WPF.
For doing this we must refer to two namespace; they are:
- System.Windows.Forms (that basically contains all the controls we can use, such as TextBox, Label, Timer, PictureBox etc.)
- System.Windows.Forms.Integration (Which basically provides a wrapper by which we can add our Windows Forms control to a WPF control, because we cannot directly add Windows controls in WPF.)
For more information about these two namespace kindly search the search engines such as Google, ask.com or any other.
Moving forward to our project, what we are going to do in this exercise is to try to create an app that will allow a user to select a folder. On Selection of the folder, all top-level files and folders within the selected folder will be displayed. The following image shows that:
Here we tried to make use of a UserControl for displaying the images along with their name. The following is the code file and design file for it.
Our UserControl consists of a PictureBox control and a Label Control wrapped inside a splitcontainer whose orientation is set to horizontal.
The following is the code behind for that.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WpfApplication2
{
public partial class DisplayPic : UserControl
{
public DisplayPic()
{
InitializeComponent();
}
public string FileName { get; set; }
public Image Image { get; set; }
public void SetData()
{
if (Image != null && FileName != "")
{
pictureBox1.Image = Image;
lblName.Text = FileName;
}
}
}
}
