Remove Link

[mosswgreentea]

I have a requirement that if the validation of the file selected fails and the onclientvalidationfailed method fires, I want to be able to give a generic error message and then automatically Remove the file.

How do I achieve this? I am able to get handle on the 'Remove' button and use remove.click(). But it does nothing. Am I missing something?

Hi Arvind Ganapathy,

You can use the following sample code to achieve this:

<form id="form1" runat="server">
  <asp:ScriptManager runat="server" ID="ScriptManager1">
  </asp:ScriptManager>
  <script type="text/javascript">
      function clientValidation(sender, args) {

      }

      function validationFailed(sender, args) {
          var $ = $telerik.$;
          var row = $(args.get_fileInputField()).parents("li")[0];
          var index = $(row).index();
          alert('validation failed');

          sender.deleteFileInputAt(index);
      }

  </script>

  <div>
      <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1"
          OnClientValidationFailed="validationFailed"
          AllowedFileExtensions=".jpeg,.jpg">
      </telerik:RadAsyncUpload>

      <asp:Button runat="server"  ID="Button1" Text="Text1" />
  </div>
  </form>

The event will kick off if file with extension different from .jpeg,.jpg is uploaded.

Object doesn't support this property or method.

 var row = $(args.get_fileInputField()).parents("li")[0];

Hello Lenny_shp,

Indeed, the 2010.2.720 version does not have the get_fileInputField() for the eventArgs of the OnClientValidationFailed event. I have logged the issue and updated your Telerik points.

So what is the workaround or substitute method to use in this case?

Hello,

Forth from Q3 2010 you can obtain the file input, if available (it is available only if the IFrame module is being used) using the following code:

<script type="text/javascript">
        function failed(sender, args) {
            var textInput = $telerik.$("input[type='text']", args.get_row())[0];
        }

    </script>

    <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" OnClientValidationFailed="failed"
        AllowedFileExtensions="gif">
    </telerik:RadAsyncUpload>

If you need to obtain the name of the file that has failed validation you can use the

var fileName = args.get_fileName()

property.
