Remarks

This differs from Instance bindings in that the property is then shared by all instances that use that type. Changing the parameter for one type affects all other instances that use that type.

Example

public bool SetNewParameterToTypeWall(UIApplication app, DefinitionFile myDefinitionFile)
{
    // Create a new group in the shared parameters file
    DefinitionGroups myGroups = myDefinitionFile.Groups;
    DefinitionGroup myGroup = myGroups.Create("MyParameters");

    // Create a type definition
    ExternalDefinitionCreationOptions option = new ExternalDefinitionCreationOptions("CompanyName", SpecTypeId.String.Text);
    Definition myDefinition_CompanyName = myGroup.Definitions.Create(option);

    // Create a category set and insert category of wall to it
    CategorySet myCategories = app.Application.Create.NewCategorySet();
    // Use BuiltInCategory to get category of wall
    Category myCategory = Category.GetCategory(app.ActiveUIDocument.Document, BuiltInCategory.OST_Walls);

    myCategories.Insert(myCategory);

    //Create an object of TypeBinding according to the Categories
    TypeBinding typeBinding = app.Application.Create.NewTypeBinding(myCategories);

    // Get the BingdingMap of current document.
    BindingMap bindingMap = app.ActiveUIDocument.Document.ParameterBindings;

    // Bind the definitions to the document
    bool typeBindOK = bindingMap.Insert(myDefinition_CompanyName, typeBinding,
      GroupTypeId.Text);
    return typeBindOK;
}
