DropDownList 下拉菜单控件

<asp:DropDownList  ID="DropDownList_spec" runat="server" >
</asp:DropDownList>

数据绑定:

?

DataTable dt = c_pub.GetSqlTable(strSQL);

          DropDownList_spec.DataSource = dt;

          DropDownList_spec.DataTextField = "StyleName";

          DropDownList_spec.DataValueField = "StyleId";

          DropDownList_spec.DataBind();

DataTextField是给用户看的
DataValueField谁给自己用的

<option value=DataValueField>DataTextField</option>
