C# 在Excel中以编程方式制作下拉列表(VSTO)的我的(好的?)方法_C#_Excel_Drop Down Menu_Vsto - Fatal编程技术网

C# 在Excel中以编程方式制作下拉列表(VSTO)的我的(好的?)方法

C# 在Excel中以编程方式制作下拉列表(VSTO)的我的(好的?)方法,c#,excel,drop-down-menu,vsto,C#,Excel,Drop Down Menu,Vsto,下面是我编写的在Excel单元格中创建下拉列表的方法,方法是从同一工作表/工作簿中的某个范围中获取可能的值 private void MakeDropDownList(string strSrcSheetName, string strDestSheetName, string strSrcRange, string strDestCell) { var currentSheet = Application.Sheets[strDestSheetName];

下面是我编写的在Excel单元格中创建下拉列表的方法,方法是从同一工作表/工作簿中的某个范围中获取可能的值

private void MakeDropDownList(string strSrcSheetName, string strDestSheetName, string strSrcRange, string strDestCell)
    {
        var currentSheet = Application.Sheets[strDestSheetName];

        var inv = Application.Sheets[strSrcSheetName];

        var items = inv.Range[strSrcRange];

        var list_items = new List<string>();

        foreach (Excel.Range cell in items)
        {
            list_items.Add(cell.Value2.ToString());
        }

        Range xlsRange;
        xlsRange = currentSheet.Range[strDestCell];

        Excel.DropDowns xlDropDowns;
        Excel.DropDown xlDropDown;
        xlDropDowns = ((Excel.DropDowns)(currentSheet.DropDowns(Missing.Value)));
        xlDropDown = xlDropDowns.Add((double)xlsRange.Left, (double)xlsRange.Top, (double)xlsRange.Width, (double)xlsRange.Height, true);

        //Add item into drop down list
        for (int i = 0; i < list_items.Count; i++)
        {
            xlDropDown.AddItem(list_items[i], i + 1);
        }
    }
但是,最终的结果是这样的:

MakeDropDownList("Units", "ReceiveBonds", "B1:B5", "E9:E18");

如您所见,下拉列表小于
E
列宽,更糟糕的是,在我从下拉列表中选择一个值后,单元格保留其原始值,即
选择单位

我做错什么了吗

我想要的是:

  • 使此下拉列表看起来像Excel的常规验证下拉列表,或者
  • 能够触发事件,将列表中的选定值设置为相应的单元格

只需在前面添加
列宽即可
