CS:
public void ddlA_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddlA= (DropDownList)sender;//获取现在的事件触发者：
GridViewRow gvr = (GridViewRow)ddlA.NamingContainer;//ddlA同属于在一个NamingContainer下
DropDownList ddlB= (DropDownList)gvr.FindControl("ddlB");//找到ddlA的DropDownList
ddlB.Enabled = false;
}
