Hello,

Our android App compiles and runs normally. However, we are facing problems when compiling our application on IOS with an error that refers to the calendar component of telerik. The error is the following:

 

XCode version 13.4

Xamarin ios SDK 15.2.0.17

Telerik Version: 2022.1.222.1

Xamarin Forms Version: 5.0.0.2337

Visual Studio: 16.11.15

MAC S.O Monterey 12.3

Thanks for the support.

An error occurred: 'Object reference not set to an instance of an object.'. Callstack: '  at Telerik.XamarinForms.PrimitivesRenderer.iOS.SideDrawerRenderer.OnElementAttached (Telerik.XamarinForms.Primitives.RadSideDrawer newElement) <0x103c213b8 + 0x00054> in <3815ecfd73d84df698419fd5cca8ff43>:0

I get this error on Iphone 5s & Ipad mini with the demo code for sidedraw

Hi all,

I am wondering if it is possible to programmatically update a menu item (for instance change the text) or also hide and then re-show an item.

I can get the items by the Items property of the TKSideDrawerSection but when the update in the item doesn't update the view, is there a way to force the menu redrawing ?

Hello,

Just curious if there's anyway to use an override for a selection color (when the user is tapping - before the action is completed so like a TouchesBegan)? I'd like t set a color as a highlight but I don't see a way to do this in the API docs or the getting started docs (or while browsing the assembly in Xamarin Studio). Is there a way to do this out of the box? Or, if not, is there a way to do this using something like TouchesBegan? I've tried to override TouchesBegan but it doesn't seem to work in the TKSideDrawerDelegate class.

Thank you!

When using SideDrawerController how can I get the current storyboard so that I can perform segue to other view controllers on side drawer item selection?

I'm confused as to how to read the comparison table on the overview page for this (http://www.telerik.com/xamarin-ui/sidedrawer)

There's nothing listed on the Windows Phone column but there is for Xamarin.Forms, which runs on Windows Phone? So if I'm using Xamarin.Forms I can use this control on Windows Phone or not?

Thanks

The SideDrawer documentation mentions a SideDrawerToggle class that can bind a drawer to a Toolbar.

Unfortunately i cannot find the class in any dll. Am i missing something or is this feature simply not enabled in the Xamarin.Android Components?
