Question

我在 Microsoft Word 文档级自定义中将行（即过程）添加到 table 中时遇到方法 (AddProcedure(Procedure procedure, Word.Table table, int procedureCol, int initialsCol, int dateCol) ) 的问题。

每一行在第 1 列包含一个描述，在第 7 列包含一个下拉列表内容控件，在第 9 列包含一个日期选择器内容控件。添加哪些过程应该取决于字符串成员的值 "engagementType"。

当使用示例 engagementType（即 "Audit"）初始化 engagementType 时，一切正常。但是当 engagementType 用空字符串初始化然后在事件处理程序中分配值 "Audit" 时，事件处理程序调用 SetupProcedures 方法然后调用 AddProcedure 方法（我相信是有问题的方法）只有一行被添加到列中的描述1，然后在尝试添加下拉列表内容控件时在第 7 列失败。

有人知道为什么会这样吗？

这是我的代码：

public partial class ThisDocument
    {
        #region Fields

        private string engagementType = "Audit";

        #endregion Fields

        #region Events

        private void ThisDocument_Startup(object sender, System.EventArgs e)
        {
            PartnerDropdownListControl.Validated += PartnerDropdownListControl_Validated;
            UpdateUI();
        }

        private void PartnerDropdownListControl_Validated(object sender, EventArgs e)
        {
            MessageBox.Show("Partner Dropdown list Validated event handler called.");

            if (PartnerDropdownListControl.Text == "JDI")
            {
                engagementType = "Audit";
                SetupProcedures(engagementType);
            }
            else
            {
                engagementType = "Review";
                SetupProcedures(engagementType);
            }
            // throw new NotImplementedException();
        }


        private void ThisDocument_Shutdown(object sender, System.EventArgs e)

我让它工作了。在调用 setupprocedures 方法之前，我需要 select partnerdropdownlist 内容控件之外的范围。
