关于EXT上传图片的问题

<ext:Window ID="ShowAddAppDetailsWindow" runat="server" title="应用的添加" AutoShow="false" Modal="true" ShowOnLoad="false" Width="400" Height="300" ButtonAlign="Right">
            <Body>
                <ext:BorderLayout ID="BorderLayout2" runat="server">
                    <Center Margins-Left ="5" Margins-Right="5" Margins-Top="5" Collapsible="true" Margins-Bottom="5">

                            <Body>
                                <ext:FormLayout ID="FormLayout3" runat="server">
                                    <ext:Anchor>
                                        <ext:TextField runat="server" ID="txtAppId" FieldLabel="ID" Width="160" Disabled="true" ></ext:TextField>
                                    </ext:Anchor>
                                    <ext:Anchor>
                                        <ext:TextField runat="server" ID="txtAppConfig" FieldLabel="Key" Width="160" Disabled="false" ></ext:TextField>
                                    </ext:Anchor>
                                    <ext:Anchor>
                                        <ext:TextField runat="server" ID="txtAppName" FieldLabel="名称" Width="160" Disabled="false" ></ext:TextField>
                                    </ext:Anchor>
                                    <ext:Anchor>
                                        <ext:ComboBox ID="txtAppStatus" FieldLabel="状态" runat="server" Width="160" Disabled="false" Editable="false">
                                            <Items>

                                                <ext:ListItem Text="禁用"  Value="1"/>
                                            </Items>
                                        </ext:ComboBox>
                                    </ext:Anchor>
                                    <ext:Anchor>
                                        <ext:FileUploadField ID="fufImage" runat="server"   FieldLabel="图片路径" Width="160"  EmptyText="请选择图片" Disabled="false" ></ext:FileUploadField>
                                    </ext:Anchor>
                                    <ext:Anchor>
                                        <ext:Button ID="btnSaveImage" runat="server" Text="保存图片" Disabled="false" >
                                            <AjaxEvents>
                                                <Click OnEvent="SaveImage_Click" />
                                            </AjaxEvents>
                                        </ext:Button>
                                    </ext:Anchor>上面是前台代码，不知道为什么，我添加了FILEUPLOADFIELD这个控件后，就会报错，说我txtAppConfig为空（我在后台做了验证的）其实是有数据，删掉这个控件又可以，而且我用了Disabled="false"，我编辑的时候Disabled=true改了，画面上也有值，但是点保存画面后，就会提示上面所说的， 那个值为空，求解

  1.   

    你在后台代码中去设置试试，哥们主要去判断回发哦if(!IsPostBack){
      绑定数据
    }string filename = FileUpload1.FileName;              //获取Execle文件名
    你是这样子去拿值的么

    Path.GetFileName(this.fufImage.FileName)我是这样取文件名的

    我把disabled换成readonly了，就OK了，不知道为什么用disabled就是娶不到值
