Type

BuildingBlock.Type property

Specifies the building block type.

public BuildingBlockType Type { get; set; }

Remarks

The building block type can influence the visibility and behavior of the building block in Microsoft Word.

Corresponds to the docPartPr.types element in OOXML.

Examples

Shows how to add a custom building block to a document.

public void CreateAndInsert()
{
    // A document's glossary document stores building blocks.
    Document doc = new Document();
    GlossaryDocument glossaryDoc = new GlossaryDocument();
    doc.GlossaryDocument = glossaryDoc;

    // Create a building block, name it, and then add it to the glossary document.
    BuildingBlock block = new BuildingBlock(glossaryDoc)
    {
        Name = "Custom Block"
    };

    glossaryDoc.AppendChild(block);

    // All new building block GUIDs have the same zero value by default, and we can give them a new unique value.
    Assert.AreEqual("00000000-0000-0000-0000-000000000000", block.Guid.ToString());

    block.Guid = Guid.NewGuid();

    // The following properties categorize building blocks
    // in the menu we can access in Microsoft Word via "Insert" -> "Quick Parts" -> "Building Blocks Organizer".
    Assert.AreEqual("(Empty Category)", block.Category);
    Assert.AreEqual(BuildingBlockType.None, block.Type);
    Assert.AreEqual(BuildingBlockGallery.All, block.Gallery);
    Assert.AreEqual(BuildingBlockBehavior.Content, block.Behavior);

    // Before we can add this building block to our document, we will need to give it some contents,
    // which we will do using a document visitor. This visitor will also set a category, gallery, and behavior.
    BuildingBlockVisitor visitor = new BuildingBlockVisitor(glossaryDoc);
    // Visit start/end of the BuildingBlock.
    block.Accept(visitor);

    // We can access the block that we just made from the glossary document.
    BuildingBlock customBlock = glossaryDoc.GetBuildingBlock(BuildingBlockGallery.QuickParts,
        "My custom building blocks", "Custom Block");

    // The block itself is a section that contains the text.
    Assert.AreEqual($"Text inside {customBlock.Name}\f", customBlock.FirstSection.Body.FirstParagraph.GetText());
    Assert.AreEqual(customBlock.FirstSection, customBlock.LastSection);
    // Now, we can insert it into the document as a new section.
    doc.AppendChild(doc.ImportNode(customBlock.FirstSection, true));

    // We can also find it in Microsoft Word's Building Blocks Organizer and place it manually.
    doc.Save(ArtifactsDir + "BuildingBlocks.CreateAndInsert.dotx");
