Display the revision selection dialog

To display the revision selection dialog for a configuration-managed model file, call the SelectRevision method of the ICommonUI object.

public void SelectRevision(ICommandContext c, ICommandParams p) 
{ 
var model = c.App.Workspace.CurrentModel; 
var modelUnit = model.ModelUnit; 

ICommonUI commonUi = c.App.Window.UI; 

IScmRevision revision = null; 

switch (modelUnit.Type) 
{ 
case "Project": 
//If the unit type is project, call the method without specifying the model unit. 
rev = commonUi.SelectRevision(); 
break; 
case "Model": 
//If the unit type is model, call the method with the model unit. 
rev = commonUi.SelectRevision(modelUnit); 
break; 
} 

if (revision == null) 
{ 
c.App.Output.WriteLine("sample", "No revision was selected."); 
return; 
} 

c.App.Output.WriteLine("sample", $"Selected revision: {revision.Revision}"); 
}
