Run IExternalCommand by pressing custom RibbonButton

Anonymous — Thu, 28 Jan 2021 08:43:51 GMT

Hello!

I apologize in advance for the question, which had already been raised, but I can't solve my problem.
I want make custom tab with button to run my external command:

public class CopySheets : IExternalCommand { public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) { UIApplication uiapp = commandData.Application; UIDocument uidoc = uiapp.ActiveUIDocument; Document doc = uidoc.Document; using (CopySheetsForm csf = new CopySheetsForm(doc, uiapp)) { csf.ShowDialog(); } return Result.Succeeded; } }

I was following this post https://thebuildingcoder.typepad.com/blog/2009/12/custom-ribbon-tab.html to write my IExternalApplication:

class App : IExternalApplication { public Result OnStartup(UIControlledApplication a) { adWin.RibbonControl ribbon = adWin.ComponentManager.Ribbon; RibbonControl ribbonControl = adWin.ComponentManager.Ribbon; RibbonTab tab = new RibbonTab(); tab.Title = "MyPlugins"; tab.Id = "MYPLUGINS_TAB_ID"; ribbon.Tabs.Add(tab); Autodesk.Windows.RibbonPanelSource srcPanel = new Autodesk.Windows.RibbonPanelSource(); srcPanel.Title = "Functions"; Autodesk.Windows.RibbonPanel panel = new Autodesk.Windows.RibbonPanel(); panel.Source = srcPanel; tab.Panels.Add(panel); adWin.RibbonButton button = new adWin.RibbonButton(); button.CommandHandler = new AdskCommandHandler("ScriptsV01.dll", "ScriptsV01.CopySheets"); adWin.ComponentManager.UIElementActivated += new EventHandler<adWin.UIElementActivatedEventArgs>(ComponentManager_UIElementActivated); panel.Source.Items.Add(button); return Result.Succeeded; } public Result OnShutdown(UIControlledApplication a) { return Result.Succeeded; } }

Then I created class, as in the above example, to be able to run my command:

public class AdskCommandHandler : System.Windows.Input.ICommand { string AssemblyName { get; set; } string ClassName { get; set; } public AdskCommandHandler(string assemblyName, string className) { AssemblyName = assemblyName; ClassName = className; } public event EventHandler CanExecuteChanged; public bool CanExecute(object a) { return true; } public void Execute(object a) { System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom( AssemblyName); IExternalCommand command = assembly.CreateInstance( ClassName) as IExternalCommand; ExternalCommandData commandData = null; string message = string.Empty; ElementSet elements = null; command.Execute(commandData, ref message, elements); } }

The promblem is, when I press button, it returns an error:

I saw a similar problem here: https://forums.autodesk.com/t5/revit-api-forum/implement-icommand-with-actual-externalcommanddata-not-null/m-p/9891057#M51380
but the solution didn't help.
So how can I run my command by pressing custom button? Any help you could provide would be much appreciated.

Hi,

Download the Revit SDK, it has loads of sample also for making you're own RibbonTab with command buttons.

See the sample "Ribbon". About the Revit SDK
