New to Telerik UI for ASP.NET AJAX? Download free 30-day trial


RadUpload has been replaced by RadAsyncUpload, Telerik’s next-generation ASP.NET upload component. If you are considering Telerik’s Upload control for new development, check out the documentation of RadAsyncUpload or the control’s product page. If you are already using RadUpload in your projects, you may be interested in reading how easy the transition to RadAsyncUpload is and how you can benefit from it in this blog post. The official support for RadUpload has been discontinued in June 2013 (Q2’13), although it is still be available in the suite. We deeply believe that RadAsyncUpload can better serve your upload needs and we kindly ask you to transition to it to make sure you take advantage of its support and the new features we constantly add to it.

The OnClientAdded client-side event occurs when a new row has just been added to the RadUpload control.

This event occurs for the initial rows that are added when the RadUpload control is first loaded, as well as any rows added in response to the Add button or client-side methods such as addFileInput() .

The event handler receives two parameters:

  1. The instance of the RadUpload control firing the event.

  2. An eventArgs parameter containing the following method:

    • get_row returns the row that was just added.

    • get_rowIndex returns the index of the row

    • get_fileInputField returns the input element of the row (<INPUT> element)

Use the OnClientAdded event to perform any last minute changes to the rows in the RadUpload control. This is the point at which you should add controls for custom fields.

The following example shows how to use the OnClientAdded event to add child controls in a different order than the one that arises from using the ControlObjectsVisibility property:

<script type="text/javascript">
    function addControls(upload, args) {
        var row = args.get_row();

<telerik:radupload id="RadUpload1" runat="server" 
    controlobjectsvisibility="AddButton, DeleteSelectedButton"
    onclientadded="addControls" />
