Restrict upload to 5 files at a time

[Peter]

I would like to restrict the number of a files that can be uploaded at a time to 5.

I reviewed this posting and applied this code:

rfeExplorer.Upload.MaxFileInputsCount = 5

But the upload modal allows an unlimited number of files to be selected.

Hi Peter,

Restricting the file count of the uploaded files is connected with the upload control, which is currently used in FileExplorer. The provided by you code is applicable only when FileExplorer is used with RadUpload (EnableAsyncUpload = "False").

In case you are working with RadAsyncUpload, though, you have two possible options to restrict the file inputs.

• Configure the RadAsyncUpload's MaxFileInputsCount and MultipleFileSelection properties in the following way (a limitation described here):
  

  protected void Page_Load(object sender, EventArgs e)
  {
      rfeExplorer.AsyncUpload.MaxFileInputsCount = 3;
      rfeExplorer.AsyncUpload.MultipleFileSelection = Telerik.Web.UI.AsyncUpload.MultipleFileSelection.Disabled;
  }

• Attach a handler to the asyncUpload's ClientFileSelected event and cancel it in case they exceed the desired count. You will also need to configure the MaxFileInputsCount here:
  

  protected void Page_Load(object sender, EventArgs e)
  {
      rfeExplorer.AsyncUpload.MaxFileInputsCount = 5;
      rfeExplorer.AsyncUpload.OnClientFilesSelected = "filesSelected";
  }

  <script>
      function filesSelected(asyncUpload, args) {
          if (args.get_count() > 5){
              alert("Please, select less than 5 files.");
              args.set_cancel(true);}
      }
  </script>

The main advantage of choosing the second approach is that the users will be allowed to select all 5 files at a time, not one by one. Hope this helps.

Thanks, this first File Explorer implementation is for a few internal users, so I am not concerned about them loosing "multi-file" selection.

Hi Peter,

In such case I am glad that both of the proposed solutions are applicable for your scenario. Should any further questions appear - do not hesitate to contact us again.
