Hi Jayesh,

The described issue is very strange. We have not encountered it so far and we are not sure what could be the reason for experiencing the problem. Could you please post your RadGrid declaration with the related code behind and WebService code. Also it will be helpful if you could provide us a live URL. Thus we will be able to gather more details about your scenario and provide you with more to-the-point answer.

Looking forward for your reply.

Kind regards,

Hi,

Thanks for your quick response.

"http://trykcentretcrm.live2.dev.radixweb.net/MasterData/Pages/managecultures.aspx"  is the live url which you will find some images are display and some are not if you refresh same twice.

Below is code for radgrid declaration

                       </telerik:RadGrid>

In Above declaration "CultureImage" columns describes Image field.

In Code behiand code is as below

protected void grdCulture_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
       {
           try
           {

               ObjWebservice = new CRMWebService();
               List<CultureBE> lstcultureBE = null;
               if (!string.IsNullOrEmpty(txtSearch.Text))
               {
                   lstcultureBE = ObjWebservice.SelectAllCulture(txtSearch.Text, string.Empty, string.Empty, string.Empty, null, string.Empty).ToList<CultureBE>();
               }
               else
               {
                   int? ISOCode = null;
                   if (!string.IsNullOrEmpty(txtISOCode.Text))
                   {
                       ISOCode = int.Parse(txtISOCode.Text);
                   }
                   lstcultureBE = ObjWebservice.SelectAllCulture(string.Empty, txtCultureName.Text, txtCurrency.Text, txtCurrecyCode.Text, ISOCode, txtCultureCode.Text).ToList<CultureBE>();
               }
               if (lstcultureBE != null)
               {
                   grdCulture.DataSource = lstcultureBE;
               }
           }
           catch (Exception ex)
           {
               ExceptionHandler.HandleException(ex);
               CommonFunctions.ModelPopupShowErrorMessage(this.Page, Common.ApplicationMessage._INTERNALEXCEPTION);
           }
       }

-- WebService code is simple as we are using 3-tire layers. it is as below

/// <summary>
      /// Method for Selecting All Culture Records
      /// </summary>
      /// <param name="SearchField">it is search criteria from it will filter from all fields</param>

      /// <returns></returns>
      [WebMethod]
      public List<CultureBE> SelectAllCulture(string SearchField, string CultureName, string Currency, string CurrecyCode, int? ISOCode, string CultureCode)
      {
          try
          {

              return new CulturesDomain().SelectAllCulture(SearchField, CultureName, Currency, CurrecyCode, ISOCode, CultureCode);
          }

Hi Jayesh,

I reviewed the code snippets which you sent us and they look correct.
Could you please verify that the web site is not hosted into the Web Farm or Web Garden, because RadBinaryImage doesn't work in WebFarm / WebGarden scenarios.
Looking forward for your reply.

All the best,

Hi,

I have checked, my site is not hosted on web farm /web garden.

Hello Jayesh,

Unfortunately we are unable to recreate the described behavior. To offer a solution we need you to send us a simple running project with which we can reproduce the issue. You could open a formal support ticket from your Telerik account and attach a ZIP file there.

Additionally could you please check if you use some kind of URL rewriting.
Looking forward for your reply.

Best wishes,

HI,

This issue came only on deployment server. on development server it is working fine.

Looking forward to your response.

Hello Jayesh,

Like I said in my previous post we are unable to reproduce the described behavior on our side. The described behavior could be caused by URL rewriting or using Web Farm or Web Garden where cached images are saved on the different web servers. Could you please try deploying the application on different server or on your PC's IIS and let me know if the issue still exists. Also it will be helpful if you could send us a small runnable example. Thus we will be able to gather more details about your scenario, deploy the application and investigate the problem.

Looking forward for your reply.

All the best,
