Binding of IsExpanded is broken

[Jaroslav Půbal]

Hello,
I have simple MVVM scenario with RadExpander.

<telerik:RadExpander  IsExpanded="{Binding IsActive, Mode=OneWay}" ...

RadExpander do not reflect changes on IsActive property.


I try to check if it not my mistake. I change to "IsEnabled".

<telerik:RadExpander  IsEnabled="{Binding IsActive, Mode=OneWay}" ...

With "IsEnabled" all working fine.

So I think IsExpanded is broken on your side.

Version 2011.1.223.1040

Hello Jaroslav Půbal,

This is a known issue in this version of RadExpander. The good news is that this is fixed in the official Q1 2011 SP1 (0419) version of RadControls.

Hi Saravanan,

I tested this issue with our official 2011 Q2 release and I confirm that it is fixed there.
Can you please try it and let us know if you still experience any problems?

All the best,

Hi,

I have the same problem, I can´t bind IsExpanded...

I have this property:

private bool _expande;
       public bool Expande
       {
           get { return _expande; }
           set { _expande = value; OnPropertyChanged("Expande"); }
       }

If I did in my constructor of ViewModel Expande = true, this works good, and the expander shows expanded, but if I try do Expande = false in other part of my viewModel doesn´t work.

Any idea why?

Thanks in advance.

Hi Nelson,

Could you please send us more of your code (XAML  and the part of the ViewModel's code that does not work) so that we could investigate and advice you better ? Thank you in advance.

Has this issue been fixed? I cannot bind to IsExpanded either.

Hello Matthias,

 I believe this is fixed long time ago. Please check out our test project with the Q1 2012 assemblies and let us know if you scenario is different.
