SharePoint custom EditorPart like default

 

Have you ever want to create the EditorPart for WebPart with the behavior : Expand / Collapse like SharePoint default.

The below code will help you to do that, with a note: Every control you create, you need add them to ControlPanel control

All the EditorPart, you should derive from MyEditorPart class

 

public abstract class MyEditorPart : EditorPart
   {

       public Panel ControlPanel = new Panel();
       Assembly spAssembly = Assembly.Load(@"Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c");
       BindingFlags bindingFlags = BindingFlags.Instance | BindingFlags.Public;
       Panel propertyPanel;
       public MCEditorPart(string PartID, string Title)
       {
           ID = PartID;
           this.Title = Title;
           ControlPanel.Attributes["id"] = this.ClientID;
           ControlPanel.Style.Add("padding", "1px");
           this.ChromeType = PartChromeType.None;
       }

       //Create the controls to render in the custom tool part editor

       protected override void CreateChildControls()
       {
           base.CreateChildControls();
           propertyPanel = (Panel)spAssembly.CreateInstance( "Microsoft.SharePoint.WebPartPages.TPPanel",
              false, bindingFlags, null,
              new object[] { Title, ControlPanel, (this.ChromeState == PartChromeState.Minimized) },
              null, null);
           Controls.Add(propertyPanel);
       }
   }
