Hi Ömer,

 
It is not very clear what exactly are you trying to achieve. If you are trying to use file filtering please refer to this help topic because it is not supported in all modules of RadAsyncUpload.
 Would you please explain what do you mean with "unavailable selection is still seeing" in the second issue because it is not very clear as well?

Thanks for your reply. but I solve it. I want to select only 5 image  but when i select 6 or more image i want to delete it. anyway. I have another poroblem now. 

  <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1"
MaxFileInputsCount="5" OnClientFileUploading="fileUploading"
</telerik:RadAsyncUpload>
  function fileUploading(radAsyncUpload, args) {
             var upload = $find("<%= RadAsyncUpload1.ClientID %>");
             var inputs = upload.getUploadedFiles();
             var k = inputs.length;
             if (k > radAsyncUpload._maxFileCount - 1) {
        radAsyncUpload.deleteFileInputAt(k);
             }
         }

for (int i = 0; i < RadAsyncUpload1.UploadedFiles.Count; i++)
        {
            string s = RadAsyncUpload1.UploadedFiles[i].FileName;
            string UploadFolder = "Uploads";
            int w = 400;
            
            string imgName = DateTime.Now.Ticks.ToString() + ".jpeg";
            if (RadAsyncUpload1.MaxFileInputsCount > 0)
            {
                string title = RadAsyncUpload1.UploadedFiles[i].GetFieldValue("TextBox");
                Helper.Resize(s, UploadFolder, w, imgName);
                Helper.Resize(s, UploadFolder, 200, "s" + imgName);
                Helper.delete(s, UploadFolder);
                RadAsyncUpload1.MaxFileInputsCount--;
            }
            Helper.delete(s, UploadFolder);
        }

Helper is my created class. Problem is when deleting file.radAsyncUpload.deleteFileInputAt() if its value k  
  although files was deleted, RadAsyncUpload1.UploadedFiles.Count  return the value of before deleting. and i put k-1 instead of k, this time  RadAsyncUpload1.UploadedFiles.Count  return correct value but MaxFileCount return wrong value. what would i do?

best wishes,
Ömer 

Hi Ömer,

You can refer to this forum thread where is shown one way implement similar functionality in the OnClientFilesUploaded event.

If you still observe the unusual behavior would you please let us know which event are you using in the code behind and what exactly is the unusual value of MaxFileCount that you are getting.
