Are you familiar with how to create a Window like the one you show?

You need to create an instance of the Window and pass it as the argument to ShowModalWindow().

You are not showing the relevant code.

In the code you showed you have a question mark as the argument. What are you passing as that argument?

Which button you click? Since you showed the code of RibbonCommandHandler, I assume the RibbonCommandHandler is SUPPOSED to be assigned to a RibbonCommandItem (typically a RibbonButton) created by your code. So, does your code creates a such RibbonCommandItem? If yes, show the code. If not, I do not see the code of RibbonCommandHandler is relevent when it is not used anywhere. It might be too much for someone who is not yet very familiar to AutoCAD .NET API programming to figure out how to create a RibbonCommandItem in order to just show an UI in AutoCAD. You should begin with creating a simply CommandMethod to show either "Hello AutoCAD" at command line, or show a UI:

[CommandMethod("ShowMyUI")]

public static void ShowMyMainWindow()

{

var win=new MainWindow()

win.DataContext=MyMainViewModel; // If you do know WPF well, you should do MVVM

var result = Application.ShowModalWindow(win);

if (result.HasValue && result.Value)

{

// If the modal UI is oked by user

// you might want to do something based on the user inputs in the UI

}

With this command "ShowMyUI" available, and you indeed created a RibbonCommandItem, which is assigned the RibbonCommandHandler, then you can set the RibbonCommandItem's CommandParameter property with this command, like

MyRibbonButton.CommandHandler = RibbonCommandHandler;

MyRibbonButton.CommandParameter = "ShowMyUI ";

...

Then in the RibbonCommandHandler, you can:

... public void Execute(object parameter) { Document doc = acadApp.DocumentManager.MdiActiveDocument; if (parameter is RibbonButton) { var commandString=((RibbonButton)parameter).CommandParameter.ToString(); var dwg=Application.DocumentManager.MdiActiveDocument; if (dwg != null) { dwg.SendStringToExecute(commandString, true, false, false); } } } ...

Hi Yuan, I created my first button and WPF UI. Next, I need to develop the MVVM pattern. Above, I pasted the ribbon button code. Could you please help me? when I'm clicking that button window not showing.

If you read my reply carefully, you should have seen this

<QUOTE>

MyRibbonButton.CommandHandler = RibbonCommandHandler;

MyRibbonButton.CommandParameter = "ShowMyUI ";

</QUOTE>

That is, in your code, simply add 1 line code:

try { RibbonButton btn = new RibbonButton(); btn.Text = "Lable"; btn.ShowText = false; btn.CommandParameter = ""; btn.ShowImage = true; btn.Image = Images.GetBitmap(@"C:\WSP\code\civil 3d c#\LabelsCross\LabelsCross\Resources\pipe.png"); btn.Orientation = System.Windows.Controls.Orientation.Vertical; btn.CommandHandler = new RibbonCommandHandler(); // Set CommandParameter to an existing command, // be it a built-in one, or your own command btn.CommandParameter = "ShowMyUI " panelSource.Items.Add(btn); btn.Size = (RibbonItemSize)250; } catch (System.Exception ex) { Application.ShowAlertDialog(ex.Message); }

Of course, you need to update your RibbonCommandHandler code as I showed in my previous reply and you would have a CommandMethod that defines the corresponding command "ShowMyUI", also showed in my previous reply.

Also, I assume your code is just concept-proving code. That is, in real world, you would not run the CreateRibbonBtn() method directly in the IExtensionApplication.Intialize(). This has been discussed in this forum many times, years. You can search "Ribbon" in this forum for the past discussion, and especially pay attention to the answers provided by @ActivistInvestor

Hi yuan i tried what you are showing the code still not working

Re: stuck in Ribbonbutton.CommandHander , i have created wpf UI

There is nothing I can tell without see all the code. I only know you have a RibbonButton available. So, the first question is: did you debug the ribbonbutton click by placing a break point in the RibbonCommandHandler? If the break point is hit, you should clearly see what the issue is, such as whether the command assigned to the CommandParameter is executed by Document.SendStringToExecute().
