    how to get the FileUploadField fullpath in code behind use it's ID ??

    How to get the FileUploadField fullpath in code behind use it's ID ,I take " 
    X.GetCmp<FileUploadField>(ID).HasFile
    " is always null !

    In code behind ,I dynamic create FileUploadField :

    Ext.Net.Container lv_Container = new Container();
                lv_Container.ID = "conIportWedge";
                lv_Container.Layout = "FormLayout";
                lv_Container.Set("container", "100%");
                lv_Container.X = 0;
                lv_Container.Y = numY;
                lv_Container.Width = Unit.Parse("380px");
                lv_Container.LabelAlign = LabelAlign.Right;
                Ext.Net.FileUploadField lv_ButJPG = new FileUploadField(); 
                lv_ButJPG.ID = "testFileUpload";               

                lv_ButJPG.Icon =Icon.ImageAdd;
                lv_ButJPG.EmptyText = "Select an Image";
                lv_ButJPG.LabelAlign = LabelAlign.Right;
                lv_ButJPG.FieldLabel = "Test";

                lv_ButJPG.Listeners.FileSelected.Handler = "Ext.net.DirectMethods.GetImage('"+lv_ButJPG.ID+"');";                
                lv_Container.Items.Add(lv_ButJPG);
                this.pnDataItemInfo.Items.Add(lv_Container);
    at DirectMethods :

    [DirectMethod]
        public void GetImage(string v_FileUploadID)
        {
            if (X.GetCmp<FileUploadField>(v_FileUploadID).HasFile)
            {                
                string lv_ImageName = string.Empty;
                if (X.GetCmp<FileUploadField>(v_FileUploadID).PostedFile != null &&
                    X.GetCmp<FileUploadField>(v_FileUploadID).PostedFile.ContentLength > 0)
                {
                    lv_ImageName = X.GetCmp<FileUploadField>(v_FileUploadID).PostedFile.FileName;
                }
            }
        }
    So ,in this way , I get result :
    X.GetCmp<FileUploadField>(v_FileUploadID).HasFile  is   "false"
     X.GetCmp<FileUploadField>(v_FileUploadID).PostedFile = null
    Please help me ,how t o get the FileUploadField selected file path use it's ID ,because i create dynamic at code behind / server side!!
    I tried if create at clint side ,this. IDName.hasFile and this .IDName .PostedFile is OK !

    Hi,

    Confirmed, X.GetCmp() doesn't work with a FileUploadField.

    Please get a file directly from a request.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void RenderFileUploadField(object sender, DirectEventArgs e)
    {
        FileUploadField fileUploadField = new FileUploadField()
            {
                ID = "FileUploadField1",
                Width = 300,
                Listeners =
                {
                    FileSelected =
                    {
                        Handler = @"Ext.net.DirectMethods.GetFileName(this.id, {
                                        isUpload : true
                                    });"
                    }
                }
            };
        this.Form.Controls.Add(fileUploadField);
        fileUploadField.Render();
    }

    [DirectMethod]
    public void GetFileName(string id)
    {
        string fileInPost = id + "-file";
        HttpPostedFile file = this.Request.Files[fileInPost];
        X.Msg.Alert("FileName", file.FileName).Show();
    }
</script>

    It works with Ext.NET v2.

    Example
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
 
<script runat="server">
    protected void RenderFileUploadField(object sender, DirectEventArgs e)
    {
        FileUploadField fileUploadField = new FileUploadField()
            {
                ID = "FileUploadField1",
                Width = 300,
                Listeners =
                {
                    Change =
                    {
                        Handler = @"App.direct.GetFileName(this.id, {
                                        isUpload : true
                                    });"
                    }
                }
            };
        this.Form.Controls.Add(fileUploadField);
        fileUploadField.Render();
    }
 
    [DirectMethod]
    public void GetFileName(string id)
    {
        X.Msg.Alert("FileName", X.GetCmp<FileUploadField>("FileUploadField1").PostedFile.FileName).Show();
    }
</script>
