Month: November 2014
Earlier this week, I used the ASP.NET AJAX RadScheduler for the first time. Once I set the necessary properties and tried to debug the page on which the RadScheduler (version 2014.2.618.45) control resided, even though I was performing no binding at all yet, I received the following error:
Page_Validators is undefined
After some research, I discovered that client-side validators work differently in ASP.NET 4.5. Microsoft’s methodology utilizes jQuery and when using a RadScriptManager you can encounter difficulties. The expectation is that you will have jQuery in the global jQuery variable, but Telerik provides it via the $telerik field.
Short of registering my own jQuery on the page to get around this, I decided to simply disable the UnobtrusiveValidationMode by adding the following key to my <appSettings> section:
<add key=”ValidationSettings:UnobtrusiveValidationMode” value=”None”/>
