You can configure the confirm dialog through a ConfirmText property that defines the confirmation text. The boolean result can be exposed in the arguments of the click event. If there is a RadWindowManager on the same page a radconfirm should be used otherwise - the browser one. For the time being the functionality can be achieved manually as illustrated in this demo - http://demos.telerik.com/aspnet-ajax/button/examples/confirm/defaultcs.aspx
I'm waiting too.
I'm waiting for this feature.
This feature has been approved approx. 2 years ago. It would be really convenient and time saving. Any update when we can expect it? Thanks!
I would think that imbedding the javascript functionality into the control, as shown in the above demo, would be a rather easy update. And to clarify: this includes adding a 'ConfirmTextFormatString' and 'ConfirmTextDataFields' in order to customize the resulting dialog.
