We are using ASP.NET and Telerik Version 2017.2.711.45 and have the following problem:
In some situations we are showing a radconfirm window using the following code:
var RWM = GetRadWindowManager();
var wdw = RWM.radconfirm(msg, CallbackFn, "auto", PUHeight + "px", null, "", "");
In IE11 everything works as expected and no request is send to the server. Unfortunately, in Firefox and Chrome RWM.radconfirm sends a request to the server. In some pages we are doing several things only if not isPostBack is true (normally only if the page is processed for the first time). Because of the unexpected request of radconfirm we are running into trouble.
Is there a way to avoid this request using radconfirm in Firefox and Chrome? If not: Is there a way to identify, that the request was send by radconfirm?
