Hello Meppy,

I'd like to bind the Dates Property to a DateCollection, which is in another class.

This is my XAML Code so far:
<planner:Calendar Theme="{Binding Path=Theme}">
   <planner:Calendar.TimetableSettings>
      <planner:TimetableSettings Dates="{Binding
          Path=DateCollection}"> ...

Now you see that I already did that with the Theme Property of the Calendar and it works perfectly. But it won't work with Dates, although I did the Binding exactly like the Theme Binding.
I tried to debug it and it doesn't even go inside get{...}.

I saw some answers how to deal with that problem in the code-behind, but I have to work strictly with the MVVM pattern.

Thanks in advance  :)

Hi,

Binding worked in my test project -
https://mindfusion.eu/_samples/DatesBinding.zip

Check if your DateCollection is a public property and of same MindFusion.Scheduling.Wpf.DateCollection type as TimetableSettings' one.

Thanks for your response, but sadly it didn't help. As I already said, I did everyting just like with the Theme and there everyting worked perfectly.

I tried to debug the DataBinding with the System.Diagnostics class and this is what I get:

System.Windows.Data Warning: 56 : Created BindingExpression (hash=53954942) for Binding (hash=11903911)

With the working Binding it looks like this:

I can't find any solution online  :(

Please attach a test project reproducing that - e.g. modify mine above to show your setup, and our developer will investigate.

Here's the small version of the solution.
Thanks for your help. :)

Below is wham I'm getting, is it the expected result? If yours is different, maybe you have older version of the control than one I'm testing with. Try replacing your assemblies with the one from my test project above.

It works now with your assemblies. Thank you very much!  :) ;D
