將數據綁定到網格視圖不起作用

Question

在下面的代碼中，我在會話中獲得了 2 個變量，我嘗試通過傳遞客戶端 ID 來綁定自定義控件中的值，在另一種情況下，我嘗試通過傳遞 doumnet id 將另一個值綁定到網格視圖。但是自定義控件綁定成功但是網格視圖無法綁定它會拋出錯誤。請幫我解決這個問題

頁面加載：

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                var SearchDoc = (SearchDoc)Session["Documentname"];
                var oDocumentID = SearchDoc.ClientID;
                var odoc = SearchDoc.DocumentID;
                DocumentServiceClient Doc = new DocumentServiceClient();
                DataSet dsField = Doc.GetClientFields(oDocumentID);
                DataSet dsField1 = Doc.GetDocumentsByDocumentID(odoc);//
                gmaFieldsContr.dtFieldsInfo = dsField.Tables[0];
                gmaFieldsContr.BindData();
                Attchdwnld.DataSource = dsField1.Tables[0];
                Attchdwnld.DataBind();}}

我解決了這個問題

 var SearchDoc = (SearchDoc)Session["Documentname"];
                var oDocumentID = SearchDoc.ClientID;
               string odoc = SearchDoc.DocumentID.ToString();
                DocumentServiceClient Doc = new DocumentServiceClient();
                DataSet dsField = Doc.GetClientFields(oDocumentID);
                DataTable dtDocument = Doc.GetDocumentsByDocumentID(odoc).Tables[0];
                gmaFieldsContr.dtFieldsInfo = dsField.Tables[0];
                gmaFieldsContr.BindData();
                Attchdwnld.DataSource = dtDocument; 
                Attchdwnld.DataBind();
