Question

Is there a way to create a SmartArt Hierarchy chart in Word from a treeview that the user creates in a C# Windows Forms application?

Thanks for any help.

try like this:

private void button2_Click(object sender, EventArgs e)
{
    Word._Application oWord;
    Word._Document oDoc;
    oWord = new Word.Application();
    oWord.Visible = true;
    oDoc = oWord.Documents.Add();

    // here try from 1 to 15 until you find the layout you are interested in...
    var myLayout = oDoc.Application.SmartArtLayouts[8];

    var smartArtShape = oDoc.Shapes.AddSmartArt(myLayout, 50, 50, 200, 200);

    smartArtShape.AlternativeText = "xxxx";
}

this puts in the document the SmartArt Shape configured to use the layout nr 8. It’s not really well documented and I spent much time in finding the right articles and samples:

this is very important to understand that you cannot create a SmartArtLayout object with the new keyword but should use any of those provided by the Application’s layout collection…
Application.SmartArtLayouts Property (Word)

Good luck 🙂
