포스트 백에서 오류가 발생했습니다.

Question

그리드가있는 웹 페이지가 있습니다. 편집을 클릭하면 팝업 모달 창이 열립니다. 팝업 모달 창 안에는 표가 있고 그 아래에 드롭 다운 목록과 저장 버튼이 있습니다. 저장을 클릭하면 선택한 값이 모달 창에있는 눈금에 삽입됩니다.

모든 것이 처음에는 잘 작동하지만, 이미 모달 창을 닫고 프로세스를 다시 수행하는 경우 (첫 번째 모눈에서 수정 클릭> 모달 창보기> ddl에서 항목 선택> 적중 저장 버튼)을 누르면 다시 게시 오류가 발생합니다. 임 첫 번째 그리드의 편집 버튼에서

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. 

코드

protected void grd_depreciation_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     Guid DepID = new Guid(grd_depreciation.DataKeys[e.NewEditIndex].Values[0].ToString()); 

     //Show the Depreciation Modal Popup 
     EditModalDepPopup.Show(); 
     //btnModalDepreciation_Click(sender,e); 

     //checks the type of depreciation.. Network or Equipment 
     DropDownList ddldescriptiondep = (DropDownList)(grd_depreciation.Rows[e.NewEditIndex].Cells[0].FindControl("ddlDescriptionDep")); 
     var incotype = (ddldescriptiondep.SelectedItem).ToString(); 
     populategrd_Editdepreciation(DepID, incotype); 

    }

여기 모달 창 (오류를 발생시키는 것) 내부의 추가 버튼의 코드입니다

       select new { a.DepMatrixID, a.IncCapexOpexID }; 

     grd_Editdepreciation.DataSource = x; 
     grd_Editdepreciation.DataBind(); 

     //Populate dropdownlist on edit depreciation modal 

     MarginAnalysi checkmarginanalysisid = MarginAnalysisAssumption_worker.get(a => a.ProjectCode == lbl_projectCode.Text).SingleOrDefault();

문제는 코드 만 업데이트 패널 내부 아니고, 마크 업 된 값이 일부 통제하지 않습니다.
