推荐答案
请查看:
您必须在后面的代码中找到该下拉菜单的控件.
然后像往常一样绑定该下拉菜单.
您可以找到下拉列表，例如:
You have to find the control of that dropdown in code behind.
then bind that dropdown as usual you bind dropdown.
You can find Dropdown like:
DropDownList drp=GridView1.FindControl("dropstatus");
现在drp是位于GridView内的DropDown.
现在绑定drp.
喜欢
Now drp is your DropDown which is inside GridView.
Now bind drp.
like
if ds contain your dataset with records then drp.DataTextField="Name"; drp.DataValueField="1" drp.DataSource=ds; drp.DataBind();
