FormView에서 파일 업로드 (매개 변수로)

Question

FormView는 ItemTemplate, EditItemTemplate 및 InsertItemTemplate의 세 가지 상태로 있습니다.

<asp:LinkButton runat="server" OnCommand="GetBenefitPdf" CommandArgument='<%# Eval("benefit_id") %>' Text="Get PDF" /> 

과 : ItemTemaplate에서 , 나는 외부 방식으로 데이터베이스에서 파일을 다운로드하는 것이 가능하게 한

protected void GetBenefitPdf(object sender, CommandEventArgs e) 
{ 
    int benefit_id = int.Parse(e.CommandArgument.ToString()); 
    Response.Redirect("GetPdf.aspx?id=" + benefit_id + "&page=ManageBenefits.aspx"); 
} 

그러나 나는 또한 InsertItemTemplate과 EditItemTemplate에서 파일 (첨부 파일)을 업로드해야 . 나는이 만든 위의 모두에서 :

<asp:FileUpload ID="filedata" runat="server" /> 

그러나 SQL 명령은 (매개 변수가 주어진다) 예외하고 있습니다 :

문자열이나 이진 데이터는 잘립니다 것입니다. 그 진술서는 만료되었습니다.

어떻게 처리해야합니까?

편집이 : SQL이 주어진다 :

또한 매개 변수가 :

<asp:Parameter Name="original_filedata" Type="Byte" /> 
<asp:Parameter Name="filedata" Type="Byte" /> 

Answer 1

좋아, 나는 그것을 해결했다.

protected void Attach(object sender, SqlDataSourceCommandEventArgs e) 
{ 
    var file = ((FileUpload)FormViewManageBenefits.FindControl("filedata")).FileBytes; 
    e.Command.Parameters["@filedata"].Value = file; 
}
