In order to prevent clicking on the same button twice, when server-side click button is handled, the RadToolBar should be disabled or the clicked button. For that reason we are going to expose the following property: SingleClick = None/Button/ToolBar. In case that you want SingleClick property on RadToolBarButton, please leave us a comment with your feedback.
More than eight years ago (Sept. 28, 2009), I initiated the thread (https://www.telerik.com/forums/how-to-prevent-double-clicking-of-any-toolbar-button) that necessitated the need for this feature. Has there been any Telerik initiative to implement this on basically any button used anywhere? Because, realistically buttons can be clicked multiple times causing unintended consequences. Thank you.

indeed a great idea
Given that toolbar buttons are often used to submit form data, I think this is a very important feature. Telerik should also look into providing single-click functionality to any of its controls which can be used to save data and which are susceptible to double clicking. For example, (and maybe this already implemented) the "Insert/Update command column icons/link buttons in the grid.
