how to only allow upload one file?

[Ray]

Hi experts,

I know this sounds stupid ... but how to remove 'add' button so user can only upload one single file or a pre defined number of files?

Many thanks,
Ray

Hi Ray,

You can set the MaxFileInputsCount property of the RadUpload. The MaxFileInputsCount property specifies the maximum number of rows that can appear in the RadUpload control. Once the RadUpload control contains this number of rows, the Add button is disabled until a row is deleted.

ASPX:

<telerik:RadUpload ID="RadUpload1" runat="server" MaxFileInputsCount="1">
</telerik:RadUpload>

Princy.

I see, however can I remove both 'delete' button and 'add' button at the same time? although the 'add' button can be disabled but still visible...

Hi Ray,

Try the following code snippet to remove the Add and Delete button after reaching the MaxFileInputsCount.

ASPX:

<telerik:RadUpload ID="RadUpload1" runat="server" MaxFileInputsCount="3" OnClientAdded="OnClientAdded">
</telerik:RadUpload>

JS:

<script type="text/javascript">
function OnClientAdded(sender, args)
   {
      if (sender.getFileInputs().length == sender.get_maxFileCount())
         {
            $telerik.$(".ruDelete").remove();
            $telerik.$(".ruAdd").remove();
         }
   }
</script>

Hope this helps.

Princy.

This seems unnecessarily complicated - I think I'll go back to the OOTB ASP.NET Upload control.

Agreed, such great controls, but you have to jump through silly hoops for some basic functionality.

Hi Kim,

Indeed the RadUpload control has some missing built-in functionalities. Please note that it has been deprecated in the RadAsyncUpload's favor and is not developed any more. The AsynUpload control on another hand can achieve the desired look only with a simple configuration, so you can consider using it in your project:

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" MaxFileInputsCount="1" MultipleFileSelection="Disabled"></telerik:RadAsyncUpload>

I hope this information will be helpful for you.
