下拉列表中存在问题。我无法将数据库下拉列表的下拉列表清空。 任何人都可以帮我解决这个问题吗？谢谢你。
答案 0 :(得分：0)
问题不是很清楚，因为这是一个错字。但是我注意到你的代码中可能有无意识的东西：你将一个项目插入到dropdownlist然后调用Databind，这实际上是覆盖了Items集合。
如果您的问题没有重新插入的项目，请切换插入位置和数据绑定调用，例如：
ddlDepoId.DataSource = entity.tblDepoes.ToList();
ddlDepoId.DataBind();
ddlDepoId.Items.Insert(0,
new ListItem
{
Enabled = true,
Text = GetLocalResourceObject("whichideas").ToString(),
Value = "0"
});
