    I set the ImageURL property of the TreeView Nodes during the NodeDataBound event.  I want to set the text for the "alt" attribute of the image.  If I set the ToolTip property of the Node, it adds the ToolTip text to the alt property of the Node image, but it also adds a "title" property with the same text to the entire text of the node.  This is unwanted.

    So, the question is: How can I set the image alt text on a node, during binding in code, without adding the same text as the title attribute for the text?

    Hello Jon,

    Thank you for contacting Telerik Support team,

    One really easy and convenient approach to achieve this behavior is to use javascript and jQuery. You could use this piece of code:

    <script type="text/javascript">
        var $ = $telerik.$;  
        $(document).ready(function () {
         $('.rtImg').each(function () {
      var $img = $(this);
      var filename = $img.attr('src')
      $img.attr('alt', filename.substring(0, filename.lastIndexOf('.')));

    Here you can find some detailed information about client-side approach.

    If you have any further questions, don't hesitate do contact us again.
