I'm trying to localize the RadColorPicker using resource-files placed in the App_GlobalResources of my website, which is working fine for most of the telerik controls (e.g. RadComboBox). In case of the RadColorPicker, adding these resource files doesn't seem change anything. For example the following code does not use any resource-file values for the texts and tooltips of "No color", "Custom color" as well as the "OK" and "cancel" buttons within the "Custom color" sub-control.
Because I'm using this control in multiple places, I dislike the way localization for RadColorPicker is beeing described in the docs (Telerik Docs: RadColorPicker). Additionally, I'm not able to find the key for at least the cancel-button within the supplied resource files (en, de, fr; which are available for download at https://www.telerik.com/account/product-download?product=RCAJAX).
As for the screenshot, the current Culture of the website is German, so I would expect the RadColorPicker to be displayed using the RadColorPicker.de-DE.resx file. Obviously these values are English though.
Any tips on the missing key for the cancel-button or the fact, that there's no localization at all?
