asp検証がサーバー上で動作していない

Question

ASP.NET検証がサーバー上で動作しないのはなぜですか？

これは、aspxページで私の検証..です

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
    class="form-control" ControlToValidate="txttitle" ErrorMessage="*" 
    ForeColor="Red" ValidationGroup="lmn"></asp:RequiredFieldValidator>` 

<div class="form-group"> 
    <label for="fileupldimg">Image</label> 
    <asp:FileUpload ID="fileupldimg" runat="server" /> 
</div> 

ボタン：

<asp:Button ID="bannerbtn" runat="server" Text="Submit" 
    OnClick="bannerbtn_Click" ValidationGroup="lmn"/> 

この検証は、ローカルホストに取り組んでいるが、サーバーを使用するときに我々は、エラーを取得：

Server Error in '/' Application.

Could not find a part of the path'G:*********\IMG'
