This version is for a document-level customization. To use this code, paste it into the ThisDocument class in your project, and call the AddDropDownListControlAtSelection method from the ThisDocument_Startup method.

private Microsoft.Office.Tools.Word.DropDownListContentControl dropDownListControl1;

private void AddDropDownListControlAtSelection()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    this.Paragraphs[1].Range.Select();

    dropDownListControl1 = this.Controls.AddDropDownListContentControl("dropDownListControl1");
    dropDownListControl1.DropDownListEntries.Add("Monday", "Monday", 0);
    dropDownListControl1.DropDownListEntries.Add("Tuesday", "Tuesday", 1);
    dropDownListControl1.DropDownListEntries.Add("Wednesday", "Wednesday", 2);
    dropDownListControl1.PlaceholderText = "Choose a day";
}

    End With
End Sub

This version is for an application-level add-in that targets the .NET Framework 4 or the .NET Framework 4.5. To use this code, paste it into the ThisAddIn class in your project, and call the AddDropDownListControlAtSelection method from the ThisAddIn_Startup method.

The following code example creates a new DropDownListContentControl for every native drop down list that the user adds to the document.

This version is for a document-level customization. To use this code, paste it into the ThisDocument class in your project. For C#, you must also attach the ThisDocument_DropDownListContentControlAfterAdd event handler to the ContentControlAfterAdd event of the ThisDocument class.

void ThisDocument_DropDownListContentControlAfterAdd(Word.ContentControl NewContentControl, bool InUndoRedo)
{
    if (NewContentControl.Type == Word.WdContentControlType.wdContentControlDropdownList)
    {
        this.Controls.AddDropDownListContentControl(NewContentControl,
            "DropDownListControl" + NewContentControl.ID);
    }
}

Private Sub ThisDocument_DropDownListContentControlAfterAdd(ByVal NewContentControl As Word.ContentControl, _
    ByVal InUndoRedo As Boolean) Handles Me.ContentControlAfterAdd

    If NewContentControl.Type = Word.WdContentControlType.wdContentControlDropdownList Then
        Me.Controls.AddDropDownListContentControl(NewContentControl, _
            "DropDownListControl" + NewContentControl.ID)
    End If
End Sub

This version is for an application-level add-in that targets the .NET Framework 4 or the .NET Framework 4.5. To use this code, paste it into the ThisAddIn class in your project. Also, you must attach the ActiveDocument_DropDownListContentControlAfterAdd event handler to the ContentControlAfterAdd event of the active document.

void ActiveDocument_DropDownListContentControlAfterAdd(
    Word.ContentControl NewContentControl, bool InUndoRedo)
{
    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    if (NewContentControl.Type == Word.WdContentControlType.wdContentControlDropdownList)
    {
        vstoDoc.Controls.AddDropDownListContentControl(NewContentControl,
            "DropDownListControl" + NewContentControl.ID);
    }
}

Private Sub ActiveDocument_DropDownListContentControlAfterAdd( _
    ByVal NewContentControl As Word.ContentControl, _
    ByVal InUndoRedo As Boolean)

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    If NewContentControl.Type = Word.WdContentControlType. _
        wdContentControlDropdownList Then
        vstoDoc.Controls.AddDropDownListContentControl(NewContentControl, _
            "DropDownListControl" + NewContentControl.ID)
    End If
End Sub

Remarks

Use this method to add a new DropDownListContentControl that is based on a native content control in the document at run time. This is useful when you create a DropDownListContentControl at run time, and you want to recreate the same control the next time the document is opened.
