------解决方案--------------------
DataSet ss = new DataSet();
this.Executeprocedure("SelectZhuceCompanyType", ref ss);
Fanwei.DataSource = ss.Tables[0].DefaultView;
Fanwei.DataTextField = "ProductCatalogName_nvarchar";
Fanwei.DataValueField = "ProductCatalogId_nvarchar";
Fanwei.DataBind();
SqlDataReader dr = this.Executeprocedure1("SelectZhuceCompanyType");
if (dr.Read())
{
Fanwei.Items.Insert(0,new ListItem(dr["ProductCatalogName_nvarchar"].ToString(), dr["ProductCatalogId_nvarchar"].ToString()));
}
单步跟踪看看Fanwei.SelectedValue是否有值
