Does anyone know how to get a button from a DNN form so it may be enabled and disabled.  I have a javaScript that is called when a row in a grid control changes but can't seem to be able to locate the button.  I know the names have been hashed for the form and I can't access the button directly by its name.  I've tried:

<script type="text/javascript" language="Javascript">

    // Enable or disable the submit button if there are any rows selected
    function radGridCustomerPool_setReportButton(sender, eventArgs)
    {
        //       var row = eventArgs.get_itemIndexHierarchical()
        var selected = eventArgs.get_tableView().get_selectedItems()
//        var cmdReport = dnn.dom.getByTagName("cmdReport");
        var body = dnn.dom.getByTagName("body")[0];
        var form = dnn.dom.getByTagName("form")[0];
        var x = form.cmdReport;
        form);
        x);
//        cmdReport.disabled = (selected.length > 0)
   }

</script>

I've inspected the form in Firebug and have noticed that the HTML button in my last post shows up but the 2 ASP:LinkCommand elements are strangely missing from the form elements.  This accounts for why I can't use the DNN Client API to gain access to them.  So now the question is why are they missing.   Is this an ASP thing or the interaction of DNN with ASP?

There is no substitute for a good understanding of why things happen!

Using dnn.dom.getByTag returns a collection of elements by tag.  Turns out an asp:LinkCommand is translated to an HTML link “<a>”.  Hence this command button is not in the <input> tag collection but the <a> link collection.

It’s important to note the the asp:LinkCommand control must have a “name” attribute to be accessible:

<asp:LinkButton CssClass="CommandButton" ID="cmdReport" runat="server" name="cmdReport" Enabled="true"

                text="Confirm Selected Customers" OnClick="cmdReport_Click"></asp:LinkButton>

In JavaScript to get a list of links on the page using the DNN client API do the following:

        // Tags can be: form, body, select, textarea, input, Script, head, a, etc
        var linkList = dnn.dom.getByTagName("a");        // HtmlCollection
        var theButton = linkList["cmdReport"];         

       // This should disable the link but it doesn’t
      theButton.disabled = true;
