Prerequisites

We recommend you go through A 'hello world' C# program before going into this example.


Creating a button

  • Add a new class to your project and name it MyCustomUI.
  • Add the following code to your class
  1. // Namespaces of the two Dynamic RibbonX assemblies 
  2. using LogismiX.Interop.DynamicRibbonX;
  3. using LogismiX.DynamicRibbonX.Core;
  4.  
  5. namespace DynamicRibbonXAddin
  6. {
  7.     class MyCustomUI2
  8.     {
  9.         private rxCustomUI _customUI;
  10.  
  11.         public MyCustomUI2()
  12.         {
  13.             // Instantiate a new rxCustomUI in a new context with id 'my_test_cs_ctx'
  14.             _customUI = rxCustomUI.create("my_test_cs_ctx", "Test C# Context");
  15.  
  16.             _customUI.clear();
  17.  
  18.             // Add a new tab and label it
  19.             rxTab myTab = _customUI.ribbon.tabs.add(new rxTab());
  20.             myTab.label = "My C# Tab";
  21.  
  22.             // Add a new group to the tab and label it
  23.             rxGroup myGroup = myTab.groups.add(new rxGroup());
  24.             myGroup.label = "My C# Group";
  25.  
  26.             // Add a new button to the group and label it
  27.             rxButton myButton = myGroup.buttons.add(new rxButton());
  28.             myButton.label = "Click Me!";
  29.  
  30.             // Render the UI
  31.             _customUI.refresh();
  32.  
  33.         }
  34.     }
  35. }
  • Modify class ThisAddin in ThisAddin.cs as follows
  1. namespace DynamicRibbonXAddin
  2. {
  3.     public partial class ThisAddIn
  4.     {
  5.         private MyCustomUI2 _myCustomUI;
  6.  
  7.         private void ThisAddIn_Startup(object sender, System.EventArgs e)
  8.         {
  9.             // Show the custom ribbon
  10.             _myCustomUI2 = new MyCustomUI();
  11.         }
  12.  
  13.         private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
  14.         {
  15.         }
  16.     }
  17. }
  • Run the add-in. If everything went according to plan a new tab labeled 'My C# Tab' will appear when the application starts and it will contain a button labeled 'Click Me!' in a group labeled 'My C# Group':

Code Analysis

  1. // Add a new group to the tab and label it
  2. rxGroup myGroup = myTab.groups.add(new rxGroup());
  3. myGroup.label = "My C# Group";

Each rxTab object has a collection of rxGroup objects (accessible through its groups property). Here we add a new group to our tab's groups and label it 'My C# Group' 


  1. // Add a new button to the group and label it
  2. rxButton myButton = myGroup.buttons.add(new rxButton());
  3. myButton.label = "Click Me!";

Each rxGroup object has a collection of rxButton objects (accessible through its buttons property). Here we add a new button to our group and label it 'Click Me!'


Remarks

  • rxCustomUI contexts are identified by their unique context ids (e.g. 'my_test_cs_ctx' above). When an rxCustomUI is created with a contextId that doesn't correspond to an existing context, the context gets created. Otherwise the rxCustomUI joins the context and shares its state with other rxCustomUIs in it.
  • You can use rxCustomUI.clear to clear a context's state


Making our code more compact

The Dynamic RibbonX API is composable, which we can take advantage to make our code more compact: 

  1. namespace DynamicRibbonXAddin
  2. {
  3.     class MyCustomUI2
  4.     {
  5.         private rxCustomUI _customUI;
  6.  
  7.         public MyCustomUI2()
  8.         {
  9.             // Instantiate a new rxCustomUI in a new context with id 'my_test_cs_ctx'
  10.             _customUI = rxCustomUI.create("my_test_cs_ctx", "Test C# Context");
  11.  
  12.             // Add a new tab and label it
  13.             _customUI.ribbon.tabs.add(new rxTab
  14.             {
  15.                 label = "My First Tab"
  16.             });
  17.  
  18.             // Render the UI
  19.             _customUI.refresh();
  20.         }
  21.     }
  22. }
