回答by Shell
Selected text is actually text which you selecting through mouse drag or by press shift key to copy/paste or delete text. You need to use just .Textinstead of .SelectedText
所选文本实际上是您通过鼠标拖动或按 shift 键复制/粘贴或删除文本选择的文本。你需要使用 just.Text而不是.SelectedText
ddlWorkType.Text = "writing"
myddlvalue = ddlWorkType.SelectedValue
if the text does not exist in assign datasource then combobox SelectedIndex will return -1 and SelectedValue will return Nothing.
如果文本在分配数据源中不存在，则组合框 SelectedIndex 将返回 -1，SelectedValue 将返回 Nothing。
