Hello, now i find out that the issue is produced by following theme

"syncfusionskin:SfSkinManager.Theme="{syncfusionskin:SkinManagerExtension ThemeName=MaterialLight}"

with that line i get the exception postet above.  If i use a other Theme example "FluentLight" the same issue.
But without theme it is working.


i cant reproduce the issue at your solution, because i have more views, and the issue is show if i swith the view as example from the schedule view to a contactsview with contacts and there the data is load async from a db.

i can sent you the hole solution if it helps.

now i think when i look at the stacktrace of the exception that there is a problem with the 

System.Windows.DependencyObject.SetValueCommon() methode wich cant get the high
from Syncfusion.UI.Xaml.Controls.DataPager.NumericButton ? 
and the theme "MaterialLight" has a issue wich let trhow the error
""NaN" ist not a valid value for property MaxHeight.
greets.

Hi, now i think i have found my mistake ?

i should use to set the Theme:

SfSkinManager.SetTheme(this, new Theme() { ThemeName = "MaterialLight" });

not set with:

syncfusionskin:SfSkinManager.Theme="{syncfusionskin:SkinManagerExtension ThemeName=MaterialLight}"

at the mainView

Second different i see at your examples, you dispose the schedule view every time

and call SuppressFinalize(this);

Should we dispose all Syncfusion controls this style ?

Disposing Schedule Control:


    protected override void Dispose(bool disposing)

    {

        if (this.Schedule != null)

        {

            this.Schedule.Dispose();

            this.Schedule = null;

        }

        base.Dispose(disposing);

    }


and the base class implements

IDisposable

:

        public void Dispose()

        {

            // Dispose of unmanaged resources.

            Dispose(true);

            // Suppress finalization.

            GC.SuppressFinalize(this);

        }

Hi Johannes,


#Query1: Regarding theme change for SfScheduler

We are glad to know that you have found the solution from our end. You can also refer to our UG documentation to know more about changing Syncfusion controls themes,


UG: https://help.syncfusion.com/wpf/themes/skin-manager?cs-save-lang=1&cs-lang=csharp#set-theme


#Query2: Regarding Dispose calling for the SfScheduler

Calling the Dispose method for the custom control (like SfScheduler) in order to clear the local objects stored in the local.


GC.SuppressFinalize is called to request the CLR that the object is disposed and there is no need to call the finalizer for that object. We are following Microsoft guidelines to dispose objects and SuppressFinalize usage. Kindly refer to the Microsoft documentation for the same,

Implement a Dispose method

SaiGanesh Sakthivel
