I'm missing RadDateRangePicker and nothing else?

[Russell]

The thing about the below error is that I have working controls on the page I'm using, it's just this one control that's missing. Why is that? Is my version too old and this isn't available in that version? The Telerik.Web.UI version is 2014.1.416.35, and yes, I know it's old, but it's what I've got. 

Help?

Hi Russell,

RadDateRangePicker is introduced in R3 2021 (version 2021.3.914) of Telerik UI for ASP.NET AJAX and to be able to use it you should upgrade to this version or a later one.

On a side note, version 2014.1.416.35 is pretty old and vulnerable to some critical vulnerabilities. It is strongly recommended to upgrade to at least R1 2020 (version 2020.1.114) or later where the known vulnerabilities in the suite are fixed. You can find more information in the Allows JavaScriptSerializer Deserialization article.

Best Regards,

I'm told we have a perpetual license for our current version - does the 2020.1.114 version include that?

I am afraid that RadDateRangePicker is not available in 2020.1.114. It has been introduced in version 2021.3.914.
