后台代码

 protected void ASPxGridDetail_RowUpdated(object sender, DevExpress.Web.Data.ASPxDataUpdatedEventArgs e)

    {



        bool isEdit = ASPxGridDetail.IsEditing;

        //ASPxUploadControl f = (ASPxUploadControl)ASPxGridDetail.TemplateControl.FindControl("uplImage");

        //ASPxUploadControl file = (ASPxUploadControl)(ASPxGridDetail.Columns["PictureUpload"].Grid.TemplateControl.FindControl("uplImage"));

        //ASPxUploadControl f = (ASPxUploadControl)this.ASPxGridDetail.TemplateControl.FindControl("uplImage");

        //GridViewDataColumn gird = (GridViewDataColumn)ASPxGridDetail.Columns["PictureUpload"] ;

        //foreach (TemplateControl ctrl in gird.Grid.TemplateControl)

        //{

        //    string ctrlName = ctrl.ToString();

        //}

        //ASPxUploadControl f = (ASPxUploadControl)ASPxGridDetail.FindEditRowCellTemplateControl(gird , "uplImage");



        string filename = f.FileName;

        string UpdateLog = "Id=" + e.Keys["Id"].ToString();

        DataAccess.SystemLog.InsertLogInfo(LoggingType.Update, "库存管理", "仓库类型维护", UpdateLog);

    }

小弟想在后台取到前台 ID为uplImage 的ASPxUploadControl 控件用了多种方法都取不到，不知道是什么原因.
查了很多帖子都找不到啊....有大神帮忙么?~
------解决方案--------------------

ASPxUploadControl f=((ASPxTextBox)this.ASPxGridView_ID.FindRowCellTemplateControl(0, this.ASPxGridView_ID.Columns["PictureUpload"] as GridViewDataColumn, "uplImage"));

ASPxGridView_ID为dxwgv:ASPxGridView ID="ASPxGridView_ID"
