Examples

Here is how to use a DesignerHost in the C# code:

using System.Collections.Generic;
using System.ComponentModel;

using Alternet.FormDesigner.WinForms;

public partial class Form1 : Form
{
    private void Form1_Load(object sender, EventArgs e)
    {
        var formDesigner = new FormDesignerControl();
        formDesigner.AutoSaveToSource = false;
        formDesigner.Dock = System.Windows.Forms.DockStyle.Fill;
        formDesigner.Parent = this;
        IList<IComponent> list = new List<IComponent>();
        foreach (IComponent component in formDesigner.DesignerHost.Container.Components)
        {
            list.Add(component);
        }
    }
}

Here is how to use a DesignerHost in the Visual Basic code:

Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports Alternet.FormDesigner.WinForms

Partial Public Class Form1
    Inherits Form

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim formDesigner = New FormDesignerControl()
        formDesigner.AutoSaveToSource = False
        formDesigner.Dock = System.Windows.Forms.DockStyle.Fill
        formDesigner.Parent = Me
        Dim list As IList(Of IComponent) = New List(Of IComponent)()

        For Each component As IComponent In formDesigner.DesignerHost.Container.Components
            list.Add(component)
        Next
    End Sub
End Class

Remarks

DesignerHost works with the WinForms designer architecture to support the designer transaction and component management. You can get an object that implements IDesignerHost by calling <xref:System.ComponentModel.Design.DesignSurface.GetService*> method.
