                                                                        </itemtemplate>

</fields>                                                                

while (reader.Read())
        {
            doDate = reader["DoDate"].ToString();
            doNumber = reader["DoNumber"].ToString();
            customerId = reader["CusId"].ToString();
            comp = reader["CompName"].ToString();

            

            DoNotb.Text = doNumber;
            doDatetb.Text = doDate;
            cidtb.Text = customerId;
            Label compname = DetailsView1.Rows[1].Cells[0].FindControl("complbl");
            comp = compname.Text;
            compname.Text = comp;
 
        }

我收到错误消息，因为"

I am getting error as "

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

在服务器端，您只需要将数据表分配给gridview的DataSource.
DataTable中应该有complbl，compAddress列

让我知道是否有任何疑问
如果解决了您的问题，请标记为解决方案

At Server side you just need to assign datatable to DataSource of gridview.
There should be column complbl,compAddress in DataTable

let me know if any queries
