属性值

类型：Microsoft.Office.Interop.Word.ContentControlListEntries

一个 ContentControlListEntries 对象，其中包含 ComboBoxContentControl 显示的项。

备注

在将 ComboBoxContentControl 添加到文档时默认不包含任何项。若要添加项，请使用 DropDownListEntries 属性的 Add 方法。

示例

下面的代码示例会在文档开头添加一个新的 ComboBoxContentControl。用户可以选择该控件显示的颜色名称，也可以键入新颜色的名称。此示例使用 DropDownListEntries 属性来指定该控件显示的颜色名称。

此版本针对的是文档级自定义项。若要使用此代码，请将其粘贴到项目内的 ThisDocument 类中，然后从 ThisDocument_Startup 方法中调用 AddComboBoxControlAtSelection 方法。

Dim comboBoxControl1 As Microsoft.Office.Tools.Word.ComboBoxContentControl

Private Sub AddComboBoxControlAtSelection()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Me.Paragraphs(1).Range.Select()
    comboBoxControl1 = Me.Controls.AddComboBoxContentControl("comboBoxControl1")
    With comboBoxControl1
        .DropDownListEntries.Add("Red", "Red", 0)
        .DropDownListEntries.Add("Green", "Green", 1)
        .DropDownListEntries.Add("Blue", "Blue", 2)
        .PlaceholderText = "Choose a color, or enter your own"
    End With
End Sub

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";
}

此版本针对的是应用程序级外接程序。若要使用此代码，请将其粘贴到项目内的 ThisAddIn 类中，然后从 ThisAddIn_Startup 方法中调用 AddComboBoxControlAtSelection 方法。

Dim comboBoxControl1 As Microsoft.Office.Tools.Word.ComboBoxContentControl

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

    Dim vstoDoc As Document = Me.Application.ActiveDocument.GetVstoObject()
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    vstoDoc.Paragraphs(1).Range.Select()
    comboBoxControl1 = vstoDoc.Controls.AddComboBoxContentControl("comboBoxControl1")
    With comboBoxControl1
        .DropDownListEntries.Add("Red", "Red", 0)
        .DropDownListEntries.Add("Green", "Green", 1)
        .DropDownListEntries.Add("Blue", "Blue", 2)
        .PlaceholderText = "Choose a color, or enter your own"
    End With
End Sub

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

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

    Document vstoDoc = this.Application.ActiveDocument.GetVstoObject();
    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";            
}
