Examples

The following code example adds a new DropDownListContentControl to the beginning of the document. Users can select the name of a day of the week in the control.

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";
}
Dim dropDownListControl1 As Microsoft.Office.Tools.Word.DropDownListContentControl

Private Sub AddDropDownListControlAtSelection()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Me.Paragraphs(1).Range.Select()
    dropDownListControl1 = Me.Controls.AddDropDownListContentControl("dropDownListControl1")
    With dropDownListControl1
        .DropDownListEntries.Add("Monday", "Monday", 0)
        .DropDownListEntries.Add("Tuesday", "Tuesday", 1)
        .DropDownListEntries.Add("Wednesday", "Wednesday", 2)
        .PlaceholderText = "Choose a day"
    End With
End Sub

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

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

private void AddDropDownListControlAtSelection()
{
    if (this.Application.ActiveDocument == null)
        return;

    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    vstoDoc.Paragraphs[1].Range.InsertParagraphBefore();
    vstoDoc.Paragraphs[1].Range.Select();

    dropDownListControl1 = vstoDoc.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";
}
Dim dropDownListControl1 As Microsoft.Office.Tools.Word.DropDownListContentControl

Private Sub AddDropDownListControlAtSelection()
    If Me.Application.ActiveDocument Is Nothing Then
        Return
    End If

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    vstoDoc.Paragraphs(1).Range.Select()
    dropDownListControl1 = vstoDoc.Controls.AddDropDownListContentControl("dropDownListControl1")
    With dropDownListControl1
        .DropDownListEntries.Add("Monday", "Monday", 0)
        .DropDownListEntries.Add("Tuesday", "Tuesday", 1)
        .DropDownListEntries.Add("Wednesday", "Wednesday", 2)
        .PlaceholderText = "Choose a day"
    End With
End Sub

Remarks

A DropDownListContentControl displays a list of items that users can select.

To access the list of items in a DropDownListContentControl, use the DropDownListEntries property.

To enable users to choose from a list of items or add their own text to the control, use a ComboBoxContentControl.

Note

This interface is implemented by the Visual Studio Tools for Office runtime. It is not intended to be implemented in your code. For more information, see Visual Studio Tools for Office Runtime Overview.

Content Controls

The DropDownListContentControl is one of eight types of content controls that you can use to design documents and templates in Microsoft Office Word. Content controls have a user interface (UI) that has controlled input like a form. You can use content controls to prevent users from editing protected sections of the document or template, and you can also bind content controls to a data source. For more information, see Content Controls.

Usage

This documentation describes the version of this type that is used in Office projects that target the .NET Framework 4 or later. In projects that target the .NET Framework 3.5, this type might have different members and the code examples provided for this type might not work. For documentation about this type in projects that target the .NET Framework 3.5, see the following reference section in the Visual Studio 2008 documentation: http://go.microsoft.com/fwlink/?LinkId=160658.
