Aurthorization

[Bill O'Neil]

I would like to use client side binding to a RESTful api that requires a token in the headers for authorization.  Is this  possible?

Hello Bill,

The Add authentication request headers with ClientDataSource KB article demonstrates how to achieve it.

var $ = $ || $telerik.$;
var old_mapTransport = Telerik.Web.UI.RadClientDataSource.prototype._mapTransport;

Telerik.Web.UI.RadClientDataSource.prototype._mapTransport = function () {
    var transport = old_mapTransport.call(this);

    transport.read.beforeSend = beforeSendHandler;
    transport.create.beforeSend = beforeSendHandler;
    transport.update.beforeSend = beforeSendHandler;
    transport.destroy.beforeSend = beforeSendHandler;

    return transport;
}

function beforeSendHandler(xhr) {
    xhr.setRequestHeader('customheader', 'custom header value');
}
