System_CAPS_noteNote

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.

The ComboBoxContentControl 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.

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.

The following code example adds a new ComboBoxContentControl to the beginning of the document. Users can select a color name displayed by the control, or they can type the name of a new color.

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

private Microsoft.Office.Tools.Word.ComboBoxContentControl comboBoxControl1;

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

    comboBoxControl1 = this.Controls.AddComboBoxContentControl("comboBoxControl1");
    comboBoxControl1.DropDownListEntries.Add("Red", "Red", 0);
    comboBoxControl1.DropDownListEntries.Add("Green", "Green", 1);
    comboBoxControl1.DropDownListEntries.Add("Blue", "Blue", 2);
    comboBoxControl1.PlaceholderText = "Choose a color, or enter your own";
}

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 AddComboBoxControlAtSelection method from the ThisAddIn_Startup method.

private Microsoft.Office.Tools.Word.ComboBoxContentControl comboBoxControl1;

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

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

    comboBoxControl1 = vstoDoc.Controls.AddComboBoxContentControl(
        "comboBoxControl1");
    comboBoxControl1.DropDownListEntries.Add("Red", "Red", 0);
    comboBoxControl1.DropDownListEntries.Add("Green", "Green", 1);
    comboBoxControl1.DropDownListEntries.Add("Blue", "Blue", 2);
    comboBoxControl1.PlaceholderText = "Choose a color, or enter your own";            
}
