MMC 中的普通winform 要FormView 类+UserControl 来实现，FormView是MMC的一个类，UserControl就是普通的那种usercontrol。当然还要实现一些特殊的接口
public class SelectionFormView : FormView
{
private SelectionControl selectionControl = null;
/// <summary>
/// Constructor
/// </summary>
public SelectionFormView()
{
}
/// <summary>
/// Handle any setup necessary
/// </summary>
/// <param name="status">asynchronous status for updating the console</param>
protected override void OnInitialize(AsyncStatus status)
{
// handle any basic stuff
base.OnInitialize(status);
// get typed reference to the hosted control
// setup by the FormViewDescription
selectionControl = (SelectionControl)this.Control;
//// load data in
Refresh();
}
...
public partial class SelectionControl : UserControl, IFormViewControl
{
SelectionFormView selectionFormView = null;
/// <summary>
/// Constructor
/// </summary>
public SelectionControl()
{
// initialize the controls
}
/// <summary>
/// Cache the associated Form View and add the actions
/// </summary>
/// <param name="parentSelectionFormView">Containing form</param>
///
void IFormViewControl.Initialize(FormView parentSelectionFormView)
{
selectionFormView = (SelectionFormView)parentSelectionFormView;
}
...
另外还要给节点一些信息：
FormViewDescription fvd = new FormViewDescription();
fvd.DisplayName = "Users (FormView)";
fvd.ViewType = typeof(SelectionFormView);
fvd.ControlType = typeof(SelectionControl);
// Attach the view to the root node
this.RootNode.ViewDescriptions.Add(fvd);
this.RootNode.ViewDescriptions.DefaultIndex = 0;
